Install WordPress and PHP 7 on CentOS

With PHP 7 around the corner, we wanted to create a dev environment to test some apps and prepare for its arrival.
PHP 7 installation for CentOS is not difficult and can be found here. With the precompiled builds, we created a VM with the appropriate software to start testing WordPress: Apache2, MariaDB and PHP 7. For this VM, we used Vagrant and VirtualBox.
VM setup involves two files: Vagrantfile, with centos.sh as a provisioner.

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(“2”) do |config|
# All Vagrant configuration is done here. The most common configuration
# options are documented and commented below. For a complete reference,
# refer to the online documentation at vagrantup.com.
# Every Vagrant virtual environment requires a box to build off of. We use CentOS.
config.vm.box = “chef/centos-7.0”
config.vm.network “private_network”, ip: “192.168.33.13”
config.vm.provision :shell, :path => “centos.sh”
# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing “localhost:8080” will access port 80 on the guest machine.
config.vm.network :forwarded_port, guest: 80, host: 8080
config.vm.synced_folder “.”, “/vagrant”, :mount_options => [“dmode=777″,”fmode=777”]
config.ssh.forward_agent = true
config.vm.provider :virtualbox do |vb|
vb.customize [“modifyvm”, :id, “–memory”, “1024”]
vb.name = “simple-php7-vagrant-centos”
end
end

centos.sh

You can find the complete VM installation guide here. It will install everything you need, and once cloned, a simple vagrant up will start the VM creation and provision process. The result will be a ready-to-install WordPress running on PHP7.
Once the provisioning is done you should be abl to access your installation on http://127.0.0.1:8080/ and see a complete phpinfo() at http://127.0.0.1:8080/info.php
The database information for installation is as follows:

  • User: wp
  • Pass: password
  • Database: wp

This is intended to be a test environment and we do not recommend implementing this on a production server. At Nexcess, we are working hard to officially support PHP7, stay tuned for more info and related posts to come!
