OpenResty is a robust, high-performance web platform based on NGINX and LuaJIT, known for its ability to handle a significant number of concurrent connections without any issue. Whether you are looking to build scalable web applications or RESTful web services, OpenResty can be an ideal choice. In this tutorial, we will walk through the process of installing OpenResty on an Ubuntu 22 system.
Prerequisites:
Note: If you have Nginx server already installed, you should stop and disable NGINX before proceeding with the installation. You can do this with the below commands.
sudo systemctl disable nginx
sudo systemctl stop nginx
Let’s get started!
Step 1: Update Your System Before we begin, it's a good practice to update the package lists for upgrades and new package installations. Open your terminal and execute the following command:
sudo apt update && sudo apt upgrade -y
Step 2: Install the prerequisite packages for the OpenResty installation.
sudo apt install --no-install-recommends wget gnupg ca-certificates
Step 3: Add the GPG key for the OpenResty repository with the following command for Debian and Ubuntu versions before 22.
wget -O - https://openresty.org/package/pubkey.gpg | sudo gpg --dearmor -o /usr/share/keyrings/openresty.gpg
Step 4: Add the OpenResty repository to the APT package manager. This step varies depending on your system’s distribution and its version.
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/openresty.gpg] http://openresty.org/package/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/openresty.list > /dev/null
Step 5: Update the package manager’s index, then install OpenResty.
sudo apt update
sudo apt install openresty
You can verify that the installation was successful by checking that the OpenResty service is running.
sudo systemctl status openresty
OpenResty serves as a simple welcome page by default, similar to the default NGINX page. You can access the welcome page by navigating to the server’s remote IP address in a web browser.
