Install LiteSpeed Web Server¶

We recommend installing LiteSpeed Web Server via litespeed.sh, and this is the procedure we cover here in the New Installations section below. We've also provided instructions for installing LSWS from SSH as root as a failsafe.

If you are looking for something else, here are some alternatives:

• Install LiteSpeed on CloudLinux
• Set up LiteSpeed Web Server AMI on AWS
• Use a LiteSpeed Web Server Docker Image

New Installations¶

cPanel, Plesk, and DirectAdmin users may prefer to use our pre-configured options to automate the installation process.

Otherwise, install interactively by executing the following command as root user:

bash <( curl https://get.litespeed.sh ) YOUR_SERIAL_NO

Be sure to replace YOUR_SERIAL_NO with the serial number you were given in the Welcome email.

Failsafe Installation¶

If the script listed above fails to download or install the software, you can install manually. These steps will not affect your current installations, and there will be no service downtime.

Download¶

Download the LiteSpeed Web Server tarball from the LiteSpeed Technologies website.

Run the following commands from SSH as root:

cd /root
wget http://www.litespeedtech.com/packages/6.0/lsws-6.0.12-ent-x86_64-linux.tar.gz

Unpack¶

Use the following command to unpack the tarball:

tar zxfv  lsws-*-ent-x86_64-linux.tar.gz

Run Installation Script¶

Access the unpacked folder:

cd lsws-*

Create a serial.no file containing your paid license serial number or your trial key:

echo "YOUR_SERIAL_NO" > serial.no

Replace YOUR_SERIAL_NO with your actual license serial number or trial key. (Double quotes are optional in this context.)

Run the install script:

./install.sh

The installer will ask you a number of questions covered in detail here.

Tips¶

• Select Upgrade if you are upgrading a current LSWS installation and want to keep your existing server configuration
• Choose the default setting when in doubt.
• For the LiteSpeed process username and groupname, set the same values as you would for Apache. Choosing the LiteSpeed default of nobody:nobody may create a file permission problem.

Install PHP¶

Enable the LiteSpeed repository and download LSPHP according to these instructions. You may have a default php.ini file installed through RPMs.
