For installing Openresty on Debian 10 follow these simple steps

Step 1: (Optional) Stop Nginx 

This step is only required if you are already running Nginx on your system. Without stopping Nginx installation of openresty might fail.

Run these commands to stop and disable Nginx

sudo systemctl disable nginx
sudo systemctl stop nginx

Step 2: Import GPG key

Run these commands to import the GPG key

sudo apt-get -y install --no-install-recommends wget gnupg ca-certificates

Above command will install some dependencies to import the key

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

This command will import the GPG key into your system

Step 3: Add Openresty repository

First, get the version of the Debian OS of your system. This command will get the version codename and save it to variable “codename”. We will use this variable in next command to add the appropriate repository for your system.

codename=`grep -Po 'VERSION="[0-9]+ \(\K[^)]+' /etc/os-release`

Now add the openresty repository for your version

echo "deb http://openresty.org/package/debian $codename openresty" \ | sudo tee /etc/apt/sources.list.d/openresty.list

Step 4: Update apt index

Use this command to update the apt index so we can download the latest package from the repository

sudo apt-get update

Step 5: Install Openresty

Now download and install the Openresty package from the repository by using this command

sudo apt-get -y install openresty

If everything goes well you will have openresty installed on your system.

You can visit the IP Address of your server to verify openresty is running. You will be greeted with a screen like this

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

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
