Note, selecting 'cmdtest' instead of 'yarn'

This is because there is a different yarn that is part on cmdtest package and is older than the yarn you are trying to install.

Solving this very simple. Instead of installing via apt or apt-get install it via npm

sudo npm install -g yarn

You can now check the version of yarn with this command

yarn -v

That’s it.

There are multiple ways to install WSL. You can directly download an Linux distribution from windows store and it will install WSL2 and your chosen Linux distribution.

The way recommended by Microsoft is by using command line. In this tutorial we will install WSL using command prompt.

Step 1: Open command prompt

Type command prompt in the search box on the taskbar. If you do not have a search box then you can click on the search icon and start typing. If you do not have that too. You can click on the windows button and start typing command prompt to search for it.

Once you find the command prompt right click on it and click on the run as administrator on the popup menu.

Step 2: Install WSL2

Run following command in the command prompt window to install WSL2. This command will also install ubuntu which is the default Linux distro for WSL. You can always install other distros afterward.

wsl --install

Windows will start downloading and installing the WSL2 and then Ubuntu to set up the Linux environment.

Step 3: Set up UNIX user and password

After the installation it will ask for a Unix username. You can choose any username it does not have to be same as windows username. Type your username and press enter.

After the username it will ask for password. Type a password of your choice for this user and press enter.

If everything goes well WSL2 and ubuntu will be successfully installed on your system.

You can verify WSL by using this command

wsl --status 

This is will you a screen like the pic below.

I you face any problem please comment below.

I searched through the web but nothing was working. So I decided to go through the server log. I know I should have done this first.

I found these lines in the syslog file:

The issue was in iptables and I needed to flush it

I ran the command highlighted in the the image above

/usr/sbin/netfilter-persistent flush 

It gave following output

I tried to to connect to the port 80 and the default nginx page loaded in browser.

Problem solved.

But doing this messed up my OpenVPN server. OpenVPN client was connecting but internet was not accessible.

So I rebooted the system to see if it fixes the problem.

It did fixed OpenVPN.

But again port 80 was inaccessible.

I checked the status of ufw and it was disable. I had enabled it before I rebooted. Iptable rules were all reset. I googled why ufw was disabled and found iptables-persistent conflicts with ufw.

I disabled iptables-persistent using this command

sudo systemctl disable netfilter-persistent

I rebooted the system again and this time ufw stayed enabled and I was able to access the port 80 and also OpenVPN was working as intended.

Nodejs can be installed directly from Ubuntu’s repository or can be installed from the Nodesource repository. As mentioned above it is developing very fast it is advisable to install it from the Nodesource repository as it contains all the latest updates.

We will be using the Nodesource repository to install Nodejs in this guide. Also, we will be installing the LTS version of nodejs which is 12.x currently. If you want to install the latest version you can check here for the versions available.

Let’s start installing Nodejs

Step 1: Update your OS:

Doing this is a good practice before installing any new package. Use these commands to update your system

sudo apt update

sudo apt upgrade

Step 2: Add Nodesource Repository

Good people at Nodesource have written this bash script that makes sit easier to add the repository. Download and run the script by using this command

curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -

If you are installing any other version change the text marked in red with the version number in the above command.

Step 3: Install Nodejs and npm 

Use the command below to install the nodejs package. It will also install the npm package that will help you download the nodejs libraries later on.

sudo apt-get install -y nodejs

Step 4: Verify installation

If everything goes well you will have Nodejs and npm installed on your system.

To check use following commands to verify the version of both npm and nodejs installed on your system.

For nodejs:

node -v

For npm

npm -v

If everything has gone well you will see something like this

If you face any problem let me know in the comments below so we can fix the problem together.

Many people prefer it to a bash shell as it is faster to use and way more configurable according to the user.

To know more about zsh you can read their FAQ here.

Installing zsh in Ubuntu is pretty straight forward.

Step 1: Update the apt index

We need to update the apt index so we can get the latest binaries available. Use the following command to update the apt index

sudo apt update

Step 2: Install zsh

Use this command to download and install the latest zsh from the ubuntu repository.

sudo apt install zsh

If everything goes well you will have zsh installed

Check it by switching to zsh by typing

zsh

If zsh is installed correctly you will see zsh prompt instead of normal bash one. If its first time you are logging to zsh it will show you a few options. Choose one which is right for you.

To go back to the bash shell type

bash

you will switch to the regular bash shell again.

If you face any problem let me know in the comments section below.

Most used feature of Openresty is the the built in Lua plugin that helps in writing Lua web app directly inside the web server without any need on installing other software. As Lua is built into the web server it makes it faster.

You can always download the source and compile it yourself but that is cumbersome and makes updating Openresty later on difficult.

For this guide, I will be using the prebuilt binaries provided by the Openresty repository.

Lets get Started

Step 1 : Import GPG Key:

GPG key helps in verifying the authenticity of the package. Run following command to get the GPG key from the official Openresty server and add in to your server.

wget -qO - https://openresty.org/package/pubkey.gpg | sudo apt-key add -

Step 2 : Add Openresty repository:

We need to be sure that ‘apt-add-repository’ command is available in our server. Run below command and it will install the required packages if not available.

sudo apt-get -y install software-properties-common

Now to add the repository use below command. It will detect the version of Ubuntu running on your server and add the appropriate repository.

sudo add-apt-repository -y "deb http://openresty.org/package/ubuntu $(lsb_release -sc) main"

Step 3 : Install Openresty

Update the apt index first

sudo apt-get update

Now run below command to download and install Openresty web server

sudo apt-get install openresty

If no error occurs you will have Openresty web server successfully installed and running on your server.

Visit your server’s IP address and you will be presented with a page like this

If you face any problem please comment below and we will try to solve it together.

We can install it easily by adding the percona’s repository to ubuntu or by downloading the source and compiling it ourselves. For this guide, I will be using the first method because that makes upgrading very easy later on.

For this guide, I will be using a freshly created 1GB VPS from Vultr hosted in Singapore.

After logging into the server via SSH go through these steps using sudo if you are not logged in as root.

Step 1: Add Percona’s repository:

To add their repository percona has created a .deb file that we need to download and install. Let’s start by downloading the package with this command:

wget https://repo.percona.com/apt/percona-release_latest.$(lsb_release -sc)_all.deb

Now install this package with this command:

dpkg -i percona-release_latest.$(lsb_release -sc)_all.deb

This will add the repository and other requirements.

Step 2: Enable the repository:

We need to enable this freshly added repository. To do so run this command:

percona-release enable psmdb-42 release

4.2 is the latest version at the time of writing and we are enabling repository for this version by the above command.

Step 3: Install Percona MongoDB

Update the local package information first

apt update

Now run this to install

apt install percona-server-mongodb

This will install the percona mongodb on your server and start it.

Check the status of mongodb by running this command:

service mongod status

You will see something like this

If the server is not running you can use this command to start

service mongod start

To stop the server you can use

service mongod stop

and to restart mongodb server

service mongod restart

If you need to change the configuration MongoDB configuration file is located at /etc/mongod.conf

Discourse is a modern style free and open source forum system that runs on Ruby on rails, uses PostgreSQL as database system and redis cache. It is used by many top companies to develop communities around their products and to provide support.

For installation Discourse team recommends a VPS or dedicated server with 2 GB RAM, although for smaller communities it can be installed on server with 1GB RAM with swap enabled . You also need SMTP for sending email and CDN for delivering static content.

You can get all these services at Alibaba Cloud. Register with Alibaba Cloud to get $300 credit to check out these and many more services.

In this guide we will be installing Discourse on Alibaba Cloud’s Elastic Compute Service (ECS) and use Directmail for sending emails and Cloud CDN for static content delivery.

Prerequisites

For this tutorial we will be needing:

• • ECS instance with at least 2GB RAM and 1 vCPU
  • A domain name or subdomain that resolve to your ECS instance
  • Cloud CDN setup to speed up our forum
  • Directmail SMTP credentials for sending email from our forum

We will need to setup all these before beginning the actual installation because discourse installer will ask for these information at the beginning of setup process.

I. Creating the ECS instance

Although if you already have a VPS or dedicated server with any other service you can use it to install Discourse but I highly recommend using ECS to reduce the latency between server and Directmail as well as CDN.

To create an ECS instance login to your Alibaba Cloud console by click here. This link will take you directly to instance selection page.

You can find the steps to creating new instance in ECS quick start guide.

This is the configuration we need in the server to install Discourse:

• An instance with 1 or more vCPU depending on your choice and at least 2GB RAM.
• For Image select Ubuntu 16.06 64 bit version.
• In storage section select Ultra Cloud Disk 40 Gib.
• Open Ports 80(http), 443(https) and 22(SSH) in security group section on networking page.

Note the IP address of the instance as we will be needing it in next steps.

II. Setting Domain name

We are doing this step early because DNS propagation takes some time. We want it propagated before we run the installer as lets encrypt require it to generate SSL certificate.

For this step you only have to add an A record in DNS configutaion of your domain that point your domain or subdomain to ECS instance’s IP address.

This is what you need to add:

Record type: A

Name: forum.example.com

Value: your.server.ip.address (eg. 192.168.1.1. You will get this in you ECS console)

This is how it looks in my DNS settings:

III. Setting up CloudCDN

This I am describing in detail as these are few setting we have to do to make it work with Discourse. For offilcial CloudCDN documentation you can go to the CloudCDN quickstart guide.

We will need to perform four main steps here:

1. Adding the CDN domain

Head over to CDN console by clicking here.

Click on the CDN Domain Name List under the CDN menu.

Click on the Add domain button on right side.

You will see a form to setup your CDN domain and origin.

In the CDN Domain field enter a subdomain of your domain name. For example cdn.example.com

In Business type select Images and Small file.

In Origin Site Type select Origin Site Domain Name.

Enter the domain name you will be using for your forum in the field that appears.

In Port field select Port 443 as Discourse installer will install Letsencrypt SSL certificate and serve your forum on port 443.

In Accelerating Region select Global Acceleration if you want to use POPs in Mainland China as well as rest of the world or you can choose Overseas Acceleration(non-chinese mainland) if you want to use only POPs putside China. To use only Chinese POPs you should select Chinese Mainland from the menu.

This is how it should look

Click on Next Button.

Your CDN will be configured in few minutes and you will be given an unique URL. You will have to create an CNAME in your domain’s DNS setting pointing yo this url.

2. Installing the SSL certificate for CDN

We need to setup SSL certificate for the CDN subdomain. If you already have the certificate you can install it and if not you can either buy it from Alibabacloud or can find free SSL certificate by a simple web search.

To install the certificate click on the manage link in front of the url in cdn url list and then click on the pen icon in front of HTTPS Secure Acceleration

Turn on the Certificate Status switch.

In Select Certificate field choose Custom Upload.

Enter a name of your choice in Certificate Name field.

Enter Certificate content and Private key in marked textboxes. These are provided to you by the certificate provider.

In Redirect Type click on the radio button that says HTTP -> HTTPS.

It should look like this

Click OK to save.

3. Setting Back-to-source Host

This setting is required so your CDN does not do a 301 redirect to your origin server.

Click pen icon in front of Back-to-source Host under Basic Configuration section.

A overlay window will open.

Switch on the Back-to-source Host button.

From the Type dropdown menu select domain name of your origin.

It should look like this

Click on OK button to save.

4. Setting the CORS HTTP header

Now click on the Set HTTP Header on side menu.

Click on Add HTTP header button on right side

A window will open.

Select Access control allow origin from the dropdown menu. And in value add *

After saving it should look like this

Note the CDN URL, we will be needing it later.

This is it for the CDN setup.

IV. Get Directmail SMTP credentials

Directmail is email service by Alibabacloud and it is one of the cheapest and most reliable service available.

Note: Email setting is the most common step where most of the new users break their forum and have to rebuild it. So be careful.

Head over to the Directmail console by clicking here.

If you have not activated it before it will ask you to do so.

For detailed documentation you can read the Directmail documentation but I will give you a short version here because there are few things we need to do to make it work with discourse.

You need to setup Directmail in 3 steps:

1. Add sender domain

This will be the domain from where the email will be send. You need to use your forum domain as it is important. For example forum.example.com.

Click on the New Domain button on the top right. A popup window will open.

Enter your forum’s domain in the the Domain field and click OK button.

A domain verification is needed to activate it.

Click on the configure link in front of your domain.

You will be presented with the DNS configuration data. You need to add these in enties DNS panel of your domain.

After you have added the DNS records to your domain’s configuration click on the Confirm Changes button at the bottom.

Now click on the verify link in front of your domain.

You will be able to send mails only after the domain status changes to Available. If the it fails to verify even after correct configuration wait for a while then verify again, sometime DNS changes takes time to take effect.

2. Add sender email address

Click on the Sender Addresses in the left menu.

Click on Create Sender Address button on the top right.

A Overlay window will open where you need to enter the data.

Fill all the fields like this to setup sender email:

Email Domains: select your forum’s domain from dropdown menu.

Account: noreply (This is important to put only noreply as account or authentication will fail and your forum will not ne able to send email.

Reply-to Address: Any email address you like where you will like to receive replies.

Mail Type: Triggered Emails.

It should look like this

Press OK to create sender address.

3. Set SMTP password

Click on the Set SMTP password link in front of the sender email address you set in previous step.

A overlay window will open where you can set your password.

Read the instructions carefully as it requires mix of lower case upper case letter and number. Use atleast 2 different uppercase letter, 2 different lowercase letters and 2 different digits for your password.

Note the sender email address and SMTP password. It will be needed while running the Discourse installer. You will also need SMTP service address that you can find here. Choose the one for the region you set your directmail account in.

V. Running the Discourse Installer

Discouse team have made it quite easy to install discourse. You only have to install docker first and download and run the installer. After few minutes and couple of question you will get your new discourse forum ready.

Login to you server via SSH

ssh root@192.168.1.1

*Replace 192.168.1.1 with your IP address.

After successful login run the following command to update your system first.

sudo apt-get update && apt-get upgrade -y

All the steps will be run as root user so run this command first

sudo -s

Install Docker

Discourse forum runs inside docker container so we will first install the latest docker

wget -qO- https://get.docker.com/ | sh

Above command will install the docker in your server.

Install GIT

apt-get install git

Download Discourse installer

Create a directory to install discourse

mkdir /var/discourse

Clone discourse doscker image inside this folder

git clone https://github.com/discourse/discourse_docker.git /var/discourse

Change to to this directory

cd /var/discourse

Run Discourse installer

Initiate setup script

./discourse-setup

Discourse will create a swap space first and then you will be asked for these information

Hostname for your Discourse? [discourse.example.com]: 
Email address for admin account(s)? [me@example.com,you@example.com]: 
SMTP server address? [smtp.example.com]: 
SMTP port? [587]: 
SMTP user name? [user@example.com]: 
SMTP password? [pa$word]: 
Let's Encrypt account email? (ENTER to skip) [me@example.com]:

Let me explain these

• Hostname for your discourse: This is the domain or subdomain that you want to use with your forum. We set it in the Step II while adding A record in your domain’s DNS.
• Email address for admin accounts: Here you enter the email address of the admin account of your forum. You can add multiple admin email separated my comma(,). this is not your SMTP sender address.
• SMTP server address: This is the address of the SMTP server of Directmail. You can find it on this page. Choose the one for the region where you have created your Directmail account. You can see your region at the top of the Directmail console.
• SMTP port: Enter 80 here as this is the port that Directmail uses for SMTP connection.
• SMTP user name: Here you enter the sender email address we created in Step V.
• SMTP password: Enter the SMTP password we set in step V.
• Let’s Encrypt account email: This is the email address that let’s encrypt uses to generate SSL certificate for your domain and send notifications regarding expiration and renewal failure. You can skip it but I suggest you do enter an email address you check regularly. Also make sure your DNS has been propagated before running the installer as it is important for generating let’s encrypt certificate.

After you have entered the information setup will show all the information you gave on the screen for review and ask for confirmation. Check it carefully and if all is correct press ENTER key. If you need to change something type n and then ENTER.

After confirmation will take around 10 minutes to setup everything.

After the setup finishes you can see your forum in the browser by visiting the URL you entered.

At this stage although your forum is working but it is not currently using CloudCDN. We will set up this now.

VI. Setting up CloudCDN

Go to the discourse directory if you are not already into it.

cd /var/discourse

Open the app.yml file in nano for editing

nano containers/app.yml

Scroll down until you find this line.

#DISCOURSE_CDN_URL: //discourse-cdn.example.com

And paste this line right below it. Make sure you keep the same indentation as line above.

DISCOURSE_CDN_URL: //cdn.example.com

*replace the url with CDN url we set in the step IV.

Press control+O and ENTER to save changes.

Press control+X and then ENTER to exit nano.

Now rebuild the app

./launcher rebuild app

Rebuild process will take about 10 minutes.

Your forum will now use CloudCDN to serve static content.

Now visit enter your forum’s URL and you will be greetied with this message

Click on the register button and fill all the fields as required to create administrator account for the forum. Forum will send you email to confirm your email address. If you do not get the email review your Directmail settings and make sure you have followed the tutorial carefully. If you need to change the SMTP setting in forum you can run the setup again by using this command inside discourse directory.

 ./discourse-setup

You will be asked all the information again and installer will also show you all the information you gave earlier.

After confirmation of your email go through the initial Discourse setup and you will be soon see your forum’s homepage.

Enjoy your new Discourse forum 🙂

Conclusion

You can install Discourse forum software quite easily on Alibabcloud’s infrastructure. You don’t have to buy from multiple providers as you get all the required services like server, SMTP and CDN from Alibabacloud and most of them are cheaper but more reliable than other providers. If you have not signed up yet register and get $300 credit to check out the Alibabacloud services.

Openresty has many built-in Nginx modules that make it a powerful web app server. A most popular feature of Openresty is built-in Lua programming language support. You can directly use Lua scripts inside the Nginx conf files. You can write a high performance web application in Lua without having to install any other package other then Openresty.

For this guide, I will be using a fresh 1GB server from Vultr hosted in Germany.

There are 2 ways to install Openresty. Either you can use the prebuilt binaries or you can download the source and compile it yourself.

For this guide, I will be using the first method as it is easier and also it makes it easier to update Openresty later.

Step 1: Import the GPG key:

We need to import a GPG key as the package we will be downloading is encrypted and this key helps in verifying the package’s authenticity. Run following command to download and add the GPG key from the Openresty official server.

wget -qO - https://openresty.org/package/pubkey.gpg | sudo apt-key add -

Step 2: Add Openresty repository:

Let us first add the apt-add-repository command

sudo apt-get -y install software-properties-common

Now run below command to add the repository. This command will detect the version of ubuntu you are using and add the appropriate repository.

sudo add-apt-repository -y "deb http://openresty.org/package/ubuntu $(lsb_release -sc) main"

Now you will have the official Openresty apt repository added to your system.

Step 3: Install Openresty:

First let’s update the apt index. Use this command to do so

sudo apt-get update

Now run this command to download and install the Openresty from its official repository

sudo apt-get install openresty

If everything goes well you will have Openresty successfully installed of your server.

Check it by visiting the IP address of your server. You will see a page like this:

Bonus tip:

If you are trying to replace previously installed Nginx with Openresty rather the installing it on fresh server then disable and stop the Nginx before following this tutorial.

Disable Nginx with this command

sudo systemctl disable nginx

and stop Nginx with this command

sudo systemctl stop nginx

If you face any problem while installing openresty please let me know in the comments section so we can solve it together.

For installing nodeBB with Nginx reverse proxy you will need to install these components:

1. NodeJS
2. MongoDB
3. Git
4. NodeBB forum software
5. Nginx

We will install them one by one by configuring each one along the way.

For this tutorial, I will be using digitalocean’s 1 GB droplet at their Bangalore datacenter.

1. Installing NodeJS:

At this time the nodeBB team suggests we should install nodejs version 8 for nodeBB. Use these commands to install it

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - 

sudo apt-get install -y nodejs

After installing verify your nodejs and npm version:

node -v  
npm -v

You will get output like this:

2. Installing MongoDB:

We will be installing MongoDB version 3.6 in this tutorial. Use these steps to install:

2.1: Import public key:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

2.2: Create a list file for MongoDB:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

2.3: Reload local package database:

sudo apt-get update

2.4: Install MongoDB packages:

sudo apt-get install -y mongodb-org

Verify MongoDB version:

mongod --version

You will get output like this: 

2.5: Configure MongoDB:

2.5.1: Open mongo shell:

mongo

only if it fails to open shell then try this command and try the above command again to enter shell:

sudo service mongod restart

2.5.2: Switch to the built-in admin database:

use admin

2.5.3: Creating users and setting passwords:

Here we will create an administrative user for MongoDB, create a new database for nodeBB and create another user for this newly created database

2.5.3.1: Create an administrative user by using this command:

db.createUser( { user: "admin", pwd: "<Enter a secure password>", roles: [ { role: "readWriteAnyDatabase", db: "admin" }, { role: "userAdminAnyDatabase", db: "admin" } ] } )

*replace <Enter a secure password> with your chosen password.

2.5.3.2: Create new database for nodeBB by using this command:

use nodebb

Now create user and password for this new database. This will be used to install nodebb.

db.createUser( { user: "nodebb", pwd: "<Enter a secure password>", roles: [ { role: "readWrite", db: "nodebb" }, { role: "clusterMonitor", db: "admin" } ] } )

*again replace <Enter a secure password> with your chosen password.

2.5.4: Exit mongo shell:

quit()

The screen should look like this:

2.5.5: Enable database authorization in the MongoDB configuration file:

Edit MongoDB config file by using nano:

nano /etc/mongod.conf

Move the cursor to the bottom of the file and paste these lines:

security: 
    authorization: enabled

remember indentation in configuration files matter. If indentations are the wrong MongoDB will fail to restart.

Your screen should look like this:

Now

press ctrl + O then enter to save

press ctrl + X to exit nano

2.5.6: Restart MongoDB

sudo systemctl restart mongod

2.5.7: Verify the administrative user created earlier can connect:

mongo -u admin -p your_password --authenticationDatabase=admin

if everything is good you will see a screen like this:

Quit MongoDB shell by using

quit()

3. Install Git:

This is a short and simple step. Just run this command:

sudo apt-get install -y git

There are chances git is already installed on your system. In either case move to the next step.

4. Install NodeBB:

Make a directory for web content:

mkdir /var/www

Go to the newly created directory by using:

cd /var/www

Clone nodeBB in this directory by this command:

git clone -b v1.9.3 https://github.com/NodeBB/NodeBB.git nodebb

*replace v1.9.3 with the latest version listed here.

Enter NodeBB directory with

cd nodebb

Initiate the installation by using this command:

./nodebb setup

This will install modules from npm and then enter the setup utility.

You will be asked a few questions regarding the database and the username password. Most of the default options will do. You will need to enter the username and password we set in step 2.5.3.2 that is the name of the username and password for the nodebb database we created.

After the database setup, it will ask for the credentials for the admin user for the new forum.

Don’t get confused. Your setup screen will look like this. I have marked the places where you will need to enter information with arrows. For the rest of the places just hit enter.

This will install the NodeBB.

Now start NodeBB by this command:

./nodebb start

Now you can view your freshly installed nodeBB forum in the browser by going to address:

http://your.server.ip.address:4567

*Replace the red text with your server’s IP address.

Here 4567 is the port number.

You will see your new forum like this:

5. Installing Nginx

In this step, we will install the Nginx web server and configure it so that you can access the forum using your domain name.

5.1: Add Nginx repository:

sudo add-apt-repository ppa:nginx/stable

Hit enter when it asks.

5.2: Update the local package database and install Nginx:

sudo apt-get update

sudo apt-get install -y nginx

Nginx is now installed. Verify it by using the command:

nginx -v

it will give something like this:

Start Nginx by using this command:

sudo systemctl start nginx

5.3: Configure Nginx:

Go to Nginx sites-available directory

cd /etc/nginx/sites-available

create a new configuration file using this command:

sudo nano forum.example.com

*Change forum.example.com with your domain name.

Paste this configuration

server {
    listen 80;

    server_name forum.example.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:4567;
        proxy_redirect off;

        # Socket.IO Support

*Again change the forum.example.com with your domain name. Your configuration file should look like this:

press ctrl + O then enter to save

press ctrl + X to exit nano

Now enter this command to go to sites-enabled directory:

cd ../sites-enabled

now link the configuration file from here:

sudo ln -s ../sites-available/forum.example.com

Reload Nginx by this:

sudo systemctl reload nginx

Now you can see your forum by entering your domain in a browser.

Just one last little thing to do to fix frequent disconnection error.

Go to nodebb directory:

cd /var/www/nodebb

Open config.json in nano

nano config.json

Change the localhost:4567 with your domain name. It should look like this:

Enter your domain name where I have put http://forum.installing.in. Do not delete the parentheses(“”)

press ctrl + O then enter to save

press ctrl + X to exit nano

restart nodeBB by:

./nodebb restart

If all went well you will now have a fully functional ubuntu + nodeBB + Nginx setup. Visit your forum by entering your domain in a browser and you can log in as administrator by using the username password we set in the setup process.

Enjoy your new nodeBB forum 🙂
