If you have a barebones install of CentOS 7 with PHP or need to install the latest PHP, it’s super easy with the REMI Yum Repository.
Download Remi and EPEL Repository packages
First, download Remi and EPEL Repository packages:
$ wget -q http://rpms.remirepo.net/enterprise/remi-release-7.rpm $ wget -q https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm $ yum -y install yum-utils yum-config-manager
Enable Remi and EPEL Repository
Install both previously downloaded packages and enable Remi PHP 7 repo:
# rpm -i remi-release-7.rpm epel-release-latest-7.noarch.rpm FOR PHP 7.0 EXECUTE: # yum-config-manager --enable remi-php70 FOR PHP 7.1 EXECUTE: # yum-config-manager --enable remi-php71 FOR PHP 7.2 EXECUTE: # yum-config-manager --enable remi-php72 FOR PHP 7.3 EXECUTE: # yum-config-manager --enable remi-php73
Current latest PHP version from Remi repository is 7.1. Amend the above command for any other subsequent PHP releases.
Install or Upgrade to PHP 7
Whether you already have PHP 5 installed on your system or you are performing a new PHP 7 installation, the below command will cater for both:
# yum install php
Alternatively, upgrade entire system with yum update command:
# yum update
Check your current PHP version
