How to install OpenLiteSpeed on Ubuntu

OpenLiteSpeed is a open source web server version of LiteSpeed Web Server Enterprise by LiteSpeed Technologies. Known for being lightweight, PageSpeed Optimization, Intelligent Cache Acceleration and more.

Getting Started

In this How to, we'll guide you step by step to install apps OpenLiteSpeed on your Ubuntu 18.04 machine.


Successfully tested with WSL (Windows Subsystem for Linux) Ubuntu 18.04 LTS (19/07/2019)

Step 1: Update your system

$ sudo apt-get update && sudo apt-get upgrade

Step 2: Remove any HTTP web servers

Remove any HTTP web server installed on your system (apache,nginx)

$ dpkg -l | grep 'apache\|nginx'

Step 3: Install required dependencies

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

Step 4: Add LiteSpeedTech Repository

$ wget -O - | bash
$ sudo apt-get update

if bash Permission denied (else skip to next Step)

If you received permission denied flags while previous command failed to execute and received similar message blow:

bash: line 32: /etc/apt/sources.list.d/lst_debian_repo.list: Permission denied register LiteSpeed GPG key /etc/apt/trusted.gpg.d/lst_debian_repo.gpg: Permission denied /etc/apt/trusted.gpg.d/lst_repo.gpg: Permission denied update the repo 

Solution: wget to your home directory


Change permissions to

chmod -x 

Execute bash (Same issue? sudo on your own risk)


Step 7: Install OpenLiteSpeed

The default directory is /usr/local/lsws after installation

$ apt-get install openlitespeed

To start the server

$ /usr/local/lsws/bin/lswsctrl start

Navigate to http://ip-here:8088 in your browser. If OpenLiteSpeed logo and a text saying Congratulations, well you know what that means. To stop the server, run the above command and replace start with stop.

To access the WebAdmin console navigate to http://ip-here:7080 (Port can be changed) with default login credensional admin : 123456

Step 8: Install PHP

OpenLiteSpeed does not come with PHP 7.2 included.

$ sudo apt-get install lsphp72 lsphp72-common lsphp72-curl lsphp72-dbg lsphp72-dev lsphp72-imap lsphp72-intl lsphp72-json lsphp72-ldap lsphp72-modules-source lsphp72-mysql lsphp72-opcache lsphp72-pgsql lsphp72-pspell lsphp72-pspell lsphp72-recode lsphp72-snmp lsphp72-sqlite3 lsphp72-sybase lsphp72-tidy

All avalible PHP versions can be found here or in your terminal:

$ apt-cache pkgnames lsphp

PHP will be located in /usr/local/lsws/lsphpXX after version you installed.

Step 9: Firewall configurations (optional)

If a firewall is installed on the machine, ensure ports to be open:

  • 80
  • 443
  • 8080
  • 7080


iptables -I INPUT -p tcp --dport 80 -j ACCEPT
iptables -I INPUT -p tcp --dport 443 -j ACCEPT
iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
iptables -I INPUT -p tcp --dport 7080 -j ACCEPT

For ufw

$ sudo ufw allow http
$ sudo ufw allow https
$ sudo ufw allow 8088/tcp
$ sudo ufw allow 7080/tcp
$ sudo ufw reload

Step 10: Configure port 80

OpenLiteSpeed default http port is 8080. In the WebAdmin console, go to Listeners under Listeners List locate adminListener and click on the Listeners Name to View.

Locate Address Settings and on its right hand side you will find the edit button. Change the fields to your needs. For sake of this guide, we will only change port 8080 to 80. For the changes to take effect you need to do a Graceful restart by pressing the Green button next to LSWS PID.

Step 11: Configure PHP 7.2 as new handler

Navigate to Server Configuration then External App and locate LiteSpeed SAPI App and edit. Make the following changes from data below.

Field New value
Name lsphp72
Address uds://tmp/lshttpd/lsphp72.sock
Max Connections 35
Command $SERVER_ROOT/lsphp72/bin/lsphp

Save and find Script Handler tab and locate LiteSpeed SAPI and edit. Change Handler Name to lsphp72 hit Save and do Graceful restart

Step 12: Cant access WebAdmin Console port problem

If you by mistake edit the port and/or cant access WebAdmin Console, stop the server and edit /usr/local/lsws/admin/conf/admin_config.conf and change adress under listener adminListener.
