Steps to install PHP 7 on CentOS 7.3

Step 1. Remove any previous PHP

First we need to remove PHP installed on CentOS. If you haven’t installed PHP, you can skip this step.

yum remove php

Step 2. Add EPEL and REMI Repository

Now we need to add or install EPEL and REMI Repository on CentOS 7.3.

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

You may need to install wget first if you don’t have it yet.

yum install wget

Now we need to enable REMI repository

nano /etc/yum.repos.d/remi-php71.repo

Now change to Enabled=1

[remi-php71]
name=Remi's PHP 7.1 RPM repository for Enterprise Linux 7 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/7/php71/$basearch/
#mirrorlist=https://rpms.remirepo.net/enterprise/7/php71/httpsmirror

enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
