How to Install OpenLiteSpeed on Ubuntu 20.04

Step 1: Update System and Install Required Packages

Before installing OpenLiteSpeed, it is important to update your system to ensure you have the latest security patches and software updates. Run the following command:

sudo apt update && sudo apt upgrade -y

After updating your system, install the required dependencies. These are necessary libraries and tools that OpenLiteSpeed relies on to function properly:

sudo apt-get install build-essential libexpat1-dev libgeoip-dev libpcre3-dev zlib1g-dev libssl-dev libxml2-dev rcs libpng-dev

Install PHP and Required Extensions

OpenLiteSpeed is optimized for PHP-based applications. To ensure proper functionality, install PHP and commonly used extensions:

sudo apt-get install php php-common php-curl php-mysql php-opcache php-imap php-opcache php-cli php-mbstring php-xml php-zip

Install MySQL

If you are planning to host a website or application that requires a database, install MySQL:

sudo apt-get install mysql-server

After installation, secure MySQL by running the following command and following the on-screen instructions:

sudo mysql_secure_installation

Step 2: Install OpenLiteSpeed

There are multiple ways to install OpenLiteSpeed on Ubuntu 20.04, and we will cover three different approaches.

Option 1: Install from the Repository

This method installs OpenLiteSpeed using the official LiteSpeed repository, ensuring you get the latest stable version.

Download the OpenLiteSpeed repository script using:

wget http://rpms.litespeedtech.com/debian/enable_lst_debian_repo.sh

Run the script to enable the repository:

sudo bash enable_lst_debian_repo.sh

Install OpenLiteSpeed:

sudo apt-get install openlitespeed

Start the OpenLiteSpeed service:

sudo systemctl start lsws

Enable OpenLiteSpeed to start at boot:

sudo systemctl enable lsws

Option 2: Install from Binary File

For those who prefer a manual installation, downloading and compiling the binary package is another option.

Download the latest stable version of OpenLiteSpeed:

wget https://openlitespeed.org/packages/openlitespeed-1.7.14.tgz

Extract the downloaded archive:

tar -xvzf openlitespeed-1.7.14.tgz

Navigate to the extracted directory:

cd openlitespeed

Run the installation script:

sudo bash install.sh

Start OpenLiteSpeed:

sudo /usr/local/lsws/bin/lswsctrl start

Option 3: One-Click Install for WordPress Users

If you are setting up a WordPress site, the one-click install script simplifies the entire process by installing OpenLiteSpeed, PHP, MySQL, and WordPress in one go.

Download the script:

wget https://raw.githubusercontent.com/litespeedtech/ols1clk/master/ols1clk.sh

Run the script:

sudo bash ./ols1clk.sh

Step 3: Configure OpenLiteSpeed

Once OpenLiteSpeed is installed, configure the administrator username and password for the web interface:

sudo bash /usr/local/lsws/admin/misc/admpass.sh

You will be prompted to enter a username for the administrative user. If you press ENTER without specifying one, the default username admin will be used. You can choose any administrative username you prefer.

Next, you will be asked to create and confirm a new password for the account. Enter your desired administrative password and press ENTER again.

Once completed, the script will confirm that the update was successful.

Output
Administrator's username/password is updated successfully!

Step 4: Configure Firewall Settings

To ensure that OpenLiteSpeed functions properly, you need to allow traffic through the necessary ports:

sudo ufw allow 8088/tcp
sudo ufw allow 7080/tcp
sudo ufw enable

• Port 8088 is used for accessing the OpenLiteSpeed web server.
• Port 7080 is used for logging into the OpenLiteSpeed admin panel.

Step 5: Access OpenLiteSpeed Web Interface

Now that OpenLiteSpeed is installed and configured, access the web interface by opening a browser and entering your server’s IP address followed by the relevant port.

To check if OpenLiteSpeed is running, visit:

http://your-server-ip:8088

To log in to the OpenLiteSpeed Web Admin, go to:

http://your-server-ip:7080

Enter the credentials set in the previous step.

Step 6: Additional Configurations

Change Default Port

By default, OpenLiteSpeed runs on port 8088. To change this, log in to the admin panel and modify the listener settings.

Enable SSL for Secure Connections

To enable HTTPS, generate an SSL certificate and configure it in OpenLiteSpeed’s admin panel.

sudo certbot --apache -d yourdomain.com
