In this tutorial, we will show you how to install OpenLiteSpeed on Debian 10 server.

Requirements

• A server running Debian 10.
• A root password is configured on your server.

Getting Started

First, you will need to update your packages with the latest version. You can update them by running the following command:

apt-get update -y
apt-get upgrade -y

Once your packages are updated, restart your system to apply configuration changes.

Next, install required dependencies with the following command:
apt-get install install build-essential libexpat1-dev libgeoip-dev libpcre3-dev libudns-dev zlib1g-dev libssl-dev libxml2 libxml2-dev rcs libpng-dev libpng-dev openssl autoconf g++ make openssl libssl-dev libcurl4-openssl-dev libcurl4-openssl-dev pkg-config libsasl2-dev libzip-dev

Once all the required dependecies are installed, you can proceed to the next step.

Install and Configure OpenLiteSpeed

By default, OpenLiteSpeed is not available in the Debian 10 default repository. So, you will need to install OpenLiteSpeed from source.

First, download the latest version of OpenLiteSpeed with the following command:
wget https://openlitespeed.org/packages/openlitespeed-1.5.2.tgz

Once the download is completed, extract the downloaded file with the following command:
tar -xvzf openlitespeed-1.5.2.tgz

Next, change the directory to the openlitespeed-1.5.2 and install OpenLiteSpeed with the following command:
cd openlitespeed-1.5.2
sh install.sh

After installing OpenLiteSpeed, you will need to configure the administrative password for the web interface. You can do it with the following command:
/usr/local/lsws/admin/misc/admpass.sh

Create admin user and password as shown below:
Please specify the user name of administrator.
This is the user name required to login the administration Web interface.

Password:
Retype password:
Administrator's username/password is updated successfully!


Next, start the OpenLiteSpeed web service with the following command:
/etc/init.d/lsws start

OpenLiteSpeed is now running and listening on port 8088. Open your web browser and type the URL http://your-server-ip:8088. You will be redirected to the following page:

Install MariaDB for OpenLiteSpeed

By default, MariaDB is available in the Debian 10 default repository. You can install it by just running the following command:
apt-get install mariadb-server mariadb-client -y

Once the MariaDB is installed, start MariaDB and enable it to start after the system reboot with the following command:
systemctl start mariadb
systemctl enable mariadb

Next, you will need to secure your MariaDB installation. You can secure it by running the following script:
mysql_secure_installation

This script will setup the root password, Remove anonymous users, Disallow root login remotely and Remove test database.
mysql_secure_installation

Answer all the questions as shown below:
Enter current password for root (enter for none):
Set root password? [Y/n]: N
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y


Once the MariaDB is secured, log in to MariaDB shell with the following command:
mysql -u root

Next, disable the plugin authentication by running the following commands:
MariaDB [(none)]>use mysql;
MariaDB [(none)]>update user set plugin='' where User='root';

Next, flush the privileges and exit from the MariaDB shell with the following command:
MariaDB [(none)]>flush privileges;
MariaDB [(none)]>exit;

Once you have finished, you can proceed to the next step.

Install PHP for OpenLiteSpeed

By default, PHP is not available in the OpenLiteSpeed repository. So, you will need to compile PHP from OpenLiteSpeed web interface.

To access the OpenLiteSpeed admin panel, open your web browser and type the URL http://your-server-ip:7080. You should see the following page:

Now, provide your admin user name and password which you have created earlier and click on the Login button. You should see the OpenLiteSpeed dashboard in the following page:

Now, log in to your server from terminal and run the pre-generated script as shown below:
/usr/local/lsws/phpbuild/buildphp_manual_run.sh

This script will download and compile PHP and related modules to your system.

You can check the installation process with the following command:
tail -f /usr/local/lsws/phpbuild/buildphp_1563016683.8.log

Once the installation has been completed successfully, you should see the following output:
