[HowTo]Upgrade PHP 5.6 to PHP 7.2 on CentOS VestaCP

[xorro]

In this tutorial I’ll show you how to upgrade PHP 5.6.xx which is by default installed by Vesta CP during installation to PHP 7.2.xx latest, I’ve tested on many server before writing this tutorial and its just working fine without any issue hence it is safe to upgrade to PHP 7.2, part of this tutorial is copied from remi repository.

Why upgrade to php 7.2 – Because it will give you security & performance boost + KICK, since WordPress will load much faster and uses less resources.

STEP 1 :

Install Remi Repository and EPEL Repository on your server :

RHEL 7

Code: Select all

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm
subscription-manager repos --enable=rhel-7-server-optional-rpms

RHEL 6

Code: Select all

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
wget http://rpms.remirepo.net/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6.rpm epel-release-latest-6.noarch.rpm
rhn-channel --add --channel=rhel-$(uname -i)-server-optional-6

CentOS 7

Code: Select all

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7.rpm epel-release-latest-7.noarch.rpm

CentOS 6

Code: Select all

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
wget http://rpms.remirepo.net/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6.rpm epel-release-latest-6.noarch.rpm

STEP 2 :

After you have installed repository you need to follow some extra configurations :
Run this command one by one for RHEL or CentOS

Code: Select all

yum install yum-utils
yum-config-manager --enable remi-php72

STEP 3 :

Now just run this command :

Code: Select all

yum update -y

You’ll see php packages are getting updated, After the update process you need to restart Apache server/php-fpm-(nginx) and check the php version from by below mentioned command:

Code: Select all

php -v

Code: Select all

[root@server ~]# php -v
PHP 7.2.7 (cli) (built: Jun 20 2018 08:21:26) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.2.7, Copyright (c) 1999-2018, by Zend Technologies

Troubleshoot

If php upgrade process fails (no update/nothing happens) or you upgraded previously from 5.6 to 7.0/7.1 then you need to run this commands to disable php 5.6/7.0/7.1 :

Code: Select all

yum-config-manager --disable remi-php56
yum-config-manager --disable remi-php70
yum-config-manager --disable remi-php71

After that follow the tutorial from STEP 2 again.

I'm stuck with (CentOS 6)

Code: Select all

[root@celebraza ~]# rhn-channel --add --channel=rhel-$(uname -i)-server-optional-6
-bash: rhn-channel: command not found

It's strange that topic starter didn't face this since rhn-channel not in standard configuration. The only googled related page
https://support.nagios.com/forum/viewto ... =6&t=50150
has solutions that don't work for me.

Can anybody help?

Hey guys!
I just followed steps like written above to update from 5.6 to 7.2 version.
After all i rebooted server, and when i do php -v i get this:

Code: Select all

PHP Warning:  Module 'mcrypt' already loaded in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library 'mysql.so' (tried: /usr/lib64/php/modules/mysql.so (/usr/lib64/php/modules/mysql.so: undefined symbol: mysqlnd_connect), /usr/lib64/php/modules/mysql.so.so (/usr/lib64/php/modules/mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
PHP Warning:  Module 'json' already loaded in Unknown on line 0
PHP 7.2.33 (cli) (built: Aug  4 2020 09:54:49) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
[root@server etc]#

I tried to find mcrypt and json in php.ini and remove those, but there are no such lines?
Also, when i upload phpinfo(); file on my server it's showing my php version is -> PHP Version 5.4.45, how is that possible? My WP installations stopped working, it's throwing errors:

Your server is running PHP version 5.4.45 but WordPress 5.4.1 requires at least 5.6.20.

Do you have any ideas what may be wrong?

Thanks! :)

See /etc/php.d folder

Dont forget to reboot apache or php-fpm after change php version.
