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 7.3.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 7.3 please be sure your script is compatible with php 7.3, part of this tutorial is copied from remi repository.
Why upgrade to php 7.3 – Because it will give you security & performance boost + KICK, since WordPress will load much faster and uses less resources. And php 7.3 is 5% faster than any other previous version.
Upgrade to php 7.4 : https://www.uxlinux.com/how-to-install-upgrade-to-php-7-4-on-rhel-centos-vestacp/
STEP 1 :
Install Remi Repository and EPEL Repository on your server :
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
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
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
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
yum install yum-utils yum-config-manager --enable remi-php73
STEP 3 :
Now just run this command :
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:
[root@server ~]# php -v PHP 7.3.0 (cli) (built: Dec 4 2018 16:12:20) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.0-dev, Copyright (c) 1998-2018 Zend Technologies with Zend OPcache v7.3.0, Copyright (c) 1999-2018, by Zend Technologies
If php upgrade process fails (no update/nothing happens) or you upgraded previously from 5.6 to 7.0/7.1/7.2 then you need to run this commands to disable php 5.6/7.0/7.1/7.2 :
yum-config-manager --disable remi-php56 yum-config-manager --disable remi-php70 yum-config-manager --disable remi-php71 yum-config-manager --disable remi-php72
After that follow the tutorial from STEP 2 again.
