Installing PHP From The LiteSpeed Debian/Ubuntu Repository

For LSWS native and OpenLiteSpeed, Installing PHP with LiteSpeed SAPI from our repository is much faster and easier than compiling it yourself. If you are not used to compiling PHP you will likely find this method more comfortable. We currently maintain LiteSpeed PHP (LSPHP) for Debian 10 (Buster), Debian 9 (Stretch), Debian 8 (Jessie), Debian 7 (Wheezy), Ubuntu 12.04 (Precise Pangolin), Ubuntu 14.04 (Trusty Tahr), Ubuntu 16.04 (Xenial Xerus), Ubuntu 18.04 (Bionic Beaver) and Ubuntu 20.04 (Focal Fossa) in this repository. As the Debian/Ubuntu Operating Systems become EOL (End of Life) we will stop updating packages for those Operating Systems in this repository without notice.

As of October 27th 2016 we have updated our signing key and encryption for better protection and safety. Do not worry if you receive an error like:

W: GPG error: http://rpms.litespeedtech.com/debian xenial Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 011AA62DEDA1F085
W: The repository 'http://rpms.litespeedtech.com/debian xenial Release' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: Invalid 'Date' entry in Release file /var/lib/apt/lists/rpms.litespeedtech.com_debian_dists_xenial_Release
W: There is no public key available for the following key IDs:
011AA62DEDA1F085 

This is because keys changed. It is a very easy fix all you have to do is run one of the following commands:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 011AA62DEDA1F085

or

sudo wget -O /etc/apt/trusted.gpg.d/lst_repo.gpg http://rpms.litespeedtech.com/debian/lst_repo.gpg

If the key that it is asking for does not match 011AA62DEDA1F085 or EDA1F085. Do not continue, check your “/etc/apt/sources.list.d/lst_debian_repo.list” file, and re-run the install script.

All the information on the new key can be found here:

If you encounter any other issues please let us know and we will help!

1. Add the LiteSpeed Debian Repository with the following command: (You must have wget installed )
   
   

   wget -O - http://rpms.litespeedtech.com/debian/enable_lst_debian_repo.sh | bash

2. Install LiteSpeed PHP with apt-get:
   
   

   apt-get install lsphpXX (XX can be 54,55,56,70,71,72,73,74)

To install other php packages for lsphpXX:

Here is a list of packages that you can install: LiteSpeed PHP Repository Packages

For example:

apt-get install lsphp73 lsphp73-mysql lsphp73-pdo lsphp73-opcache

Available packages can be checked using the following command:

apt-cache search lsphpXX (XX can be 54,55,56,70,71,72,73,74)

When you run the enable_lst_debian_repo.sh script, it will automatically execute these lines of code:

echo "deb http://rpms.litespeedtech.com/debian/ demo main" > /etc/apt/sources.list.d/lst_debian_repo.list

This detects your OS Ubuntu/Debian distro (demo in this example) and adds associated LiteSpeed Debian/Ubuntu Repository info to Debian's source list folder.

wget -O /etc/apt/trusted.gpg.d/lst_repo.gpg http://rpms.litespeedtech.com/debian/lst_repo.gpg 

This fetches LiteSpeed Tech's GPG public key and adds it to APT's trusted key zone.

apt-get update

This updates the APT package list. Packages installed from the LiteSpeed repository with the apt-get command will automatically authenticate the GPG signature of the repository.

REMEMBER: You do not need to execute these steps yourself! The enable_lst_debian_repo.sh script does it for you!

• LiteSpeed PHP XX will be installed to /usr/local/lsws/lsphpXX. This is not the usual directory LSWS checks for PHP so we will need to direct LSWS to this directory after installation.
  
  To do this, open the WebAdmin Console and navigate to Configuration » Server » External App and click “Edit” next to the “LSAPI App” Type. Change the path in the Command field to /usr/local/lsws/lsphpXX/bin/lsphp and click “Save” at the top right. LSWS should now be using the newly installed lsphp binary.
• A “php.ini” file will have been installed to /usr/local/lsws/lsphpXX/etc/php.ini. You may modify and otherwise tailor this file to suit your needs.
• Packages in the apt repo are usually only built for Long Term Support (LTS) releases due to the fact that regular releases have too short of a life span before End of Life (EOL). In most cases, non-LTS releases will still work with packages from the prior LTS release.
• For opcache module, you won't find separate packages such as lsphp5x-opcache, but it has been included in the main package. The module location is /usr/local/lsws/lsphp55/lib/php/20121212/opcache.so. By default, it is not enabled in php.ini. You should modify the main php.ini such as /usr/local/lsws/lsphp55/etc/php.ini by adding the following:

zend_extension=opcache.so
opcache.enable=1
