Hello all,

For native OpenLiteSpeed/LiteSpeed, we can install PHP from LiteSpeed official repository.

  1. wget -O - | sudo bash


Since the image should have this repository installed, we can simply install packages directory like this

Example for lsphp80

  1. apt-get install lsphp80 lsphp80-common lsphp80-mysql lsphp80-memcached lsphp80-redis lsphp80-opcache lsphp80-curl lsphp80-imagick -y

OpenLiteSpeed comes with PHP detached mode by default, so need to restart PHP with the command killall -9 lsphp to make settings take effect.


In your case, you can replace lsphp80 with lsphp74 and it should work

Thank you @qtwrk

  1. When I do php --version I get “PHP 7.4.3” and should be 7.4.9 Already reboot the droplet and nothing changed.

About the PHP73 I am afraid to remove it again, so I decided to leave it.

Thanks for all
