How to Install PHP 5.6 on Oracle Linux 7

Oracle Linux is a free RHEL based Linux distro. We will install PHP 5.6 on an Oracle Linux 7 server.

First, enable EPEL repo

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Enable Remi repo

yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Install yum-utils package

yum install yum-utils

Enable remi-php56

yum-config-manager --enable remi-php56

Install PHP 5.6 with

yum install -y php php-bcmath php-cli php-common php-devel php-gd \
    php-imap php-intl php-json php-ldap php-lz4 php-mbstring php-mysqlnd \
    php-soap php-intl php-opcache php-xml php-pdo

This will only install the CLI version of PHP 5.6. To make Apache work with PHP 5.6, install

yum install php-pecl-http.x86_64

This will create file /etc/httpd/conf.d/php.conf, that enable PHP module in Apache.

Restart apache webserver

systemctl restart httpd

Now Apache will be able to serve PHP files.
