How to Install LiteSpeed

Many control panels like cPanel will come with an auto Installer for LiteSpeed. However, if you want to install LiteSpeed but you either don't have a supported control panel or you have a standalone Apache server, these instructions will help guide you through the installation process.

  1. Run the following commands from SSH as root:
    • cd /root
    • Note: Make sure to replace the values in the URL for your specific OS and the version of LiteSpeed you wish to download
      • lsws-4.2.12-ent-x86_64-linux = LSWS Enterprise 4.2.12 for 64-bit Linux
      • lsws-4.2.10-std-i386-linux = LSWS Standard 4.2.10 for 32-bit Linux
      • lsws-4.2.12-ent-x86_64-freebsd6 = LSWS Enterprise 4.2.12 for 64-bit FreeBSD 6.x
  2. Unpack the ZIP file with tar -zxvf lsws-4.2.19-ent-x86_64-linux.tar.gz
  3. Type in cd lsws-4.2.19 into your command terminal
  4. Next, run the installation script:
    • cd lsws-4.2.12
    • For the Enterprise Edition, make sure to put the license file (trial.key or paid license file in the unpacked folder)
  5. Accept the EULA for Litespeed
  6. Click Enter for the default (/usr/local/lsws)
  7. Set up an Admin username (Don't use Admin!)
  8. Set up the password for your Admin account
  9. Set up the email address for your Admin account
  10. Set your control panel if you have one. (InterWorx = 5)
  11. "0" to replace Apache
  12. "1" to use SuEXEC or "2" if you have DirectAdmin
  13. "Y" to start it automatically when the server starts
  14. Click Enter
  15. If you have Apache still on, turn it off using:
    • service httpd stop
      chkconfig httpd off
  16. "Y" to start LiteSpeed now

Your LiteSpeed Web Server should now start successfully. Now you should test and switch everything to LiteSpeed if it didn't automatically change. If your application doesn't allow you to run an offest prot for LSWS, then you should stop your Apache web server and start LSWS for testing.

Go to http://your-ip:7080/ after you've started running your server to verify.

If that's the case, the first thing you need to do is compile PHP with LSAPI.

If you get an error on the first step, you need to install patch:

yum install patch
