How Can I upgrade PHP7.0 to PHP 7.4?

Hello,

Do you get a specific error when you try to install the newer version?

I could suggest following the steps from the first answer here:

https://www.digitalocean.com/community/questions/how-to-upgrade-php-version-from-7-2-to-php-7-3-in-ubuntu-16-04

Make sure to first backup your Droplet, as this is a major upgrade, so if anything goes wrong, you would be able to revert back to the working version of your website/server.

Alternatively, what you could do is to deploy a new server with Ubuntu 20.04 and the latest PHP version via this link here:

https://marketplace.digitalocean.com/apps/openlitespeed-wordpress

Then once the server is up and running you could move your website over using a plugin like this one here:

Best,

Hi @angus,

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

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

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
