All commands – with sudo

sudo yum -y update
sudo yum groupinstall "Development Tools" -y
sudo wget
sudo tar -zxvf lsws*
sudo cd lsws-5.3.7
sudo ./
rpm -ivh

LiteSpeed is alternative to the Apache web server that offers greater performance  capabilities and uses less server resources. LiteSpeed has all the features of Apache including mod_rewrite, .htaccess, and mod_security. LiteSpeed also loads Apache configuration files directly and functions as a drop-in replacement for the Apache web server.


LiteSpeed is proprietary software and requires a licence to use. For evaluation purposes you can to obtain a trial license key from LiteSpeed and copy it to the installation directory. If you already have a production license, copy the serial number from the confirmation email to the installation directory before you start the installation.

This tutorial is specific to CentOS 7 server and assumes you have root access. If you are not logged in as a root then switch to the root user.

System Update

Before starting up any installation it’s best to perform a system update first.

yum -y update

This will be executed at the command line. The “y” switch will pass the automatic confirmation to the yum package manager.

Installing the Developer Tools for LiteSpeed

The first part of the installation is to install the Development Tools. You can install Development Tools by executing the following command in the terminal.

yum groupinstall "Development Tools" -y

The following modules and dependencies will be installed.

Downloading LiteSpeed

We need to download the latest stable release of LiteSpeed web server. You can check for latest release on the LiteSpeed Website . 

Right-click the download button and copy the link and execute on your server using the wget command as shown below.


The downloaded LiteSpeed package is in compressed format. We will need to extract it to a convenient location.

tar -zxvf lsws*

Installing LiteSpeed

Change directory to the newly created LiteSpeed directory.

cd lsws-5.3.7

Install the package by executing the script


The first step of the installation is agreeing to the Terms of Service. Go through the terms and type “Yes” to continue the installation.

Important: In order to continue installation you must agree with above 
           license terms by typing "Yes" with capital "Y"!

Do you agree with the above license?

Next, the installation will ask to specify the directory to install LiteSpeed. Choose a custom destination for the installation; or to install it in the default directory simply press ‘Enter’.

Note: You must have permissions to create and manage the installation directory.

Please specify the destination directory. You must have permissions to 
create and manage the directory. It is recommended to install the web server 
at /opt/lsws, /usr/local/lsws or in your home directory like '~/lsws'.

ATTENTION: The user 'nobody' must be able to access the destination

Destination [/usr/local/lsws]:

Enter a preferred username for the administrator.

Please specify the user name of the administrator.
This is the user name required to log into the administration web interface.

User name [admin]:

If you want to use the name “admin”, simply press ‘Enter’. Best practice is to choose a unique username. This makes it more difficult for hackers to guess. Enter a custom username for the administrator and press ‘Enter’.

You will now be asked to enter a password for the administrator account which is used to access the web interface.

Please specify the administrator's password.
This is the password required to log into the administration web interface.


The username and password are required to log into the administration web interface. Please make sure to keep the username and password somewhere safe for further use.

The next prompt asks you to provide a valid email address to send notifications about anything related to your server/LiteSpeed install. LiteSpeed will send notifications/alerts to the email addresses that you specify.

Please specify administrators' email addresses.
It is recommended to specify a real email address,
Multiple email addresses can be set by a comma 
delimited list of email addresses. Whenever something
abnormal happened, a notification will be sent to 
emails listed here.

Email addresses [root@localhost]:

Next, provide the user under which this server should run. You can either create a new user with non-root privileges or press ‘Enter’ to choose the default user “nobody”.

As you are the root user, you must choose the user and group
whom the web server will be running as. For security reason, you should choose
a non-system user who does not have login shell and home directory such as

User [nobody]:

Do the same for the next prompt.

Please choose the group that the web server running as.

User 'nobody' is the member of following group(s): nobody
Group [nobody]:

Next, specify the port number for LiteSpeed.

Please specify the port for normal HTTP service.
Port 80 is the standard HTTP port, only 'root' user is allowed to use 
port 80, if you have another web server running on port 80, you need to
specify another port or stop the other web server before starting LiteSpeed
Web Server.
You can access the normal web page at http://<YOUR_HOST>:<HTTP_PORT>/

HTTP port [8088]: 80

We have to setup the administration web interface that manages LiteSpeed web server. This web interface will need to run on another port, 7080 (default). Please leave it as default, unless you want it to listen on another port.

Please specify the HTTP port for the administration web interface,
which can be accessed through http://<YOUR_HOST>:<ADMIN_PORT>/

Admin HTTP port [7080]:

You will now be able to reach the administration web interface by typing

Next, choose whether or not to enable PHP to use a CMS (WordPress or Joomla). Type “Y” to enable PHP or “n” not to use it.

You can setup a global script handler for PHP with the pre-built PHP engine
shipped with this package now. The PHP engine runs as Fast CGI which 
outperforms Apache's mod_php. 
You can always replace the pre-built PHP engine with your customized PHP 

Setup up PHP [Y/n]: Y

The next prompt is for advanced users. Simply press ‘Enter’ to continue.

Suffix for PHP script(comma separated list) [php]:

Next, you will be asked if you want to enable AWStats. AWStats is an open source Web analytics reporting tool that generated statistics so that you can see detailed information about your site visitors.

Type “y” if you need AWStats, or “N” if you don’t need this.

AWStats is a popular log analyzer that generates advanced web server 
statistics. LiteSpeed web server seamlessly integrates AWStats into 
its Web Admin Interface. AWStats configuration and statistics update
have been taken care of by LiteSpeed web server.

Note: If AWStats has been installed already, you do not need to
install again unless a new version of AWStats is available.

Would you like to install AWStats Add-on module [y/N]? N

The next prompt allows you to start LiteSpeed automatically after the server restarts, to prevent downtime. It is recommended to type “Y”.

Would you like to have LiteSpeed Web Server started automatically
when the server restarts [Y/n]? Y

To start LiteSpeed now, type “Y” or If you want to start it later manually, type “n”.

[OK] The startup script has been successfully installed!
Would you like to start it right now [Y/n]? Y

If you see the following message, then the installation has been completed successfully.

LiteSpeed Web Server started successfully! Have fun!
