  2. And OpenLiteSpeed packages.
  3. How to delete the old PHP 7.3 ?

Thanks for all

Hello there, You can try this way- Open a terminal window on your Ubuntu Server. Issue the command sudo apt-get install phpmyadmin php-mbstring php-gettext -y. When prompted, type your sudo password. Allow the installation to complete. I hope this will help Best regards

Hello all,

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

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

Thank you @qtwrk for your support. The last step “apt remove lsphp73” breaks my wordpress site, maybe, somewhere is using the old 7.3.

I need to find what and where is using 7.3

Thanks for all your kindness
