Ansible Role: PHP

Installs PHP on RedHat Enterprise Linux or CentOS 6.x servers.

Requirements

None.

Role Variables

Available variables are listed below, along with default values (see vars/main.yml):

php_enablerepo: ""

If you have enabled any additional repositories (might I suggest geerlingguy.repo-epel or geerlingguy.repo-remi), those repositories can be listed under this variable (e.g. remi,epel). This can be handy, as an example, if you want to install the latest version of PHP 5.4, which is in the Remi repository.

php_memory_limit: "256M"
php_max_execution_time: "60"
php_upload_max_filesize: "64M"

Some commonly-adjusted PHP ini directives. Adjust to suit your system.

php_apc_cache_by_default: "1"
php_apc_shm_size: "96M"

Two APC ini directives that are often customized on a system. Set php_apc_cache_by_default to 0 to disable APC by default (so you could enable it on a host-by-host basis). Set the php_apc_shm_size so it will hold all your application code in memory with a little overhead (fragmentation or APC running out of memory will slow down PHP dramatically).

This Ansible role assumes you're including php-pecl-apc in the list of php_packages below. It's rarely a good idea to run a PHP < 5.5 installation without some kind of opcode cache, and APC works great for PHP 5.3 and 5.4.

php_date_timezone: "America/Chicago"

Explicitly set PHP's date timezone system-wide.

php_packages: []

A list of the PHP packages to install. You'll likely want to install common packages like php, php-cli, php-devel and php-pdo, and you can add in whatever other packages you'd like (for example, php-gd for image manipulation, or php-ldap if you need to connect to an LDAP server for authentication).

Dependencies

• geerlingguy.apache

Example Playbook

- hosts: webservers
  vars_files:
    - vars/main.yml
  roles:
    - { role: geerlingguy.php }

Inside vars/main.yml:

php_memory_limit: "128M"
php_max_execution_time: "90"
php_upload_max_filesize: "256M"
php_packages:
  - php
  - php-cli
  - php-common
  - php-devel
  - php-gd
  - php-mbstring
  - php-pdo
  - php-pecl-apc
  - php-xml

TODO

• Make role more flexible, allowing APC to be excluded from php_packages list.
• Use lineinfile rather than templates to make configuration changes.
• Remove apache dependency (better way of using handler?).
