Nginx cannot change php version

Hi, virtualmin install script with LEMP flag on centos 8 have php7.2 installed by default. I have created a virtual server. After installing php 7.4 as recommended here my virtual server does not change its php version to 7.4, even after I run yum remove php72.

Changing php version on virtualmin > server configuration > PHP options is not working, PHP script execution mode does not have FCGId nor FPM checked.

How to change my virtual server php version?

After the install, did you click on System Settings → Re-Check Config and what does it detect?

It clearly detects two, though? (But you don’t have a php-cgi package installed for the 7.4.19 version, so it obviously cannot use that version for CGI and FCGI.)

You should be using php-fpm, unless you have a compelling reason to do otherwise.

You almost certainly shouldn’t uninstall the default php version. But, that’s not what you’re doing with this command…you’re not doing anything with this command, as there is no php72 package on a stock CentOS 8 system. But, even if you got the package names right, it’s not the right thing to do (you’d make a mess).

Oh, wait…now that I look closer, I think you have succeeded in removing the default PHP packages (that wasn’t the command that did it, though). The default version is 7.2.24 on my systems, but the package names are not php72*.

Our docs definitely don’t tell you to do that.

And, that explains why you can’t select things (though it’s a bug that it’s not letting you fix it). You removed the version Virtualmin had configured for your sites and now it’s confused…something outside of its understanding has happened.

So, two things:

Use FPM. It’s the preferred/recommended execution mode for most deployments.
Show us what php packages you have installed if you continue to have problems (rpm -qa|grep php).

It’s maybe possible that switching to FPM can sort things out. There is some kind of UI bug here, triggered by PHP versions that were in use being removed. But, I’m pretty sure you should be able to select a version that is available.

I cannot chose either FCGId nor FPM. No radio button checked, and after checking it, and save it, the radio button become not checked again.

I can return the enabled version back to centos appstream 7.2 if needed. Since I removed the default PHP installed from virtualmin script, should I install it again using this command?
dnf -y install php72-php-{cli,pdo,fpm,zip,gd,xml,mysqlnd,opcache}

I have tried to install php 7.4 from remi repo. Should I change back to default? How can I do it?

Whoops · November 19, 2021, 7:51am

It may be slightly corrupted. You have 2 versions of 7.4 - its fine to remove default 7.2 on a new server but it needs to be a clean uninstall before you change stream to 7.4, I use 7.4.26 and only FPM or disabled option enabled. Thats my choice and personal preference but I would recommend FPM.

One option is to remove both 7.4 versions completely. Disable 7.4.19 stream and re install 7.4.26 or back to 7.2

yum --enablerepo=remi-php74 install php
yum --enablerepo=remi-php7.4 install php

Thats your 2 versions. Disable the one you dont need. Make sure everything is removed before reinstalling version you want. yum remove “php-*” -y

Get one version working first then add a different version later as needed if this is required.

Assume you already have these repos:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf install dnf-utils

See available PHP versions:
sudo dnf module list php

sudo dnf module install php:remi-7.4
sudo dnf install -y php-fpm php-cli php-common php-zip php-gd php-mcrypt php-mbstring php-curl php-xml php-pear php-bcmath php-json php-pdo
sudo systemctl enable php-fpm
sudo systemctl restart httpd
