I have forked the geerlingguy's PHP role in order to add the configuration of the php.ini file for the CLI environment.
Installs PHP on RedHat/CentOS and Debian/Ubuntu servers.
Must be running a separate web server, such as Nginx or Apache.
Available variables are listed below, along with default values (see defaults/main.yml
):
php_packages: []
A list of the PHP packages to install (OS-specific by default). 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).
php_enable_webserver: true
If your usage of PHP is tied to a web server (e.g. Apache or Nginx), leave this default value. If you are using PHP server-side or to run some small application, set this value to false
so this role doesn't attempt to interact with a web server.
php_webserver_daemon: "httpd"
The default values for the HTTP server deamon are httpd
(used by Apache) for RedHat/CentOS, or apache2
(also used by Apache) for Debian/Ubuntu. If you are running another webserver (for example, nginx
), change this value to the name of the daemon under which the webserver runs.
php_enablerepo: ""
(RedHat/CentOS only) 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_executable: "php"
The executable to run when calling PHP from the command line. You should only change this if running php
on your server doesn't target the correct executable, or if you're using software collections on RHEL/CentOS and need to target a different version of PHP.
PHP-FPM is a simple and robust FastCGI Process Manager for PHP. It can dramatically ease scaling of PHP apps and is the normal way of running PHP-based sites and apps when using a webserver like Nginx (though it can be used with other webservers just as easily).
When using this role with PHP running as php-fpm
instead of as a process inside a webserver (e.g. Apache's mod_php
), you need to set the following variable to true
:
php_enable_php_fpm: false
You will also need to override the default php_packages
list and add php-fpm
(RedHat/CentOS) or php5-fpm
(Debian/Ubuntu) to the list.
This role does not manage fpm-specific www pool configuration (found in /etc/php-fpm.d/www.conf
on RedHat/CentOS and /etc/php5/fpm/pool.d/www.conf
on Debian/Ubuntu), but rather allows you to manage those files on your own. If you change that file, remember to notify the restart php-fpm
handler so PHP picks up the new settings once in place. Settings like pm.max_children
and other pm.*
settings can have a dramatic impact on server performance, and should be tuned specifically for each application and server configuration.
php_use_managed_ini: true
By default, all the extra defaults below are applied through the php.ini included with this role. You can self-manage your php.ini file (if you need more flexility in its configuration) by setting this to false
(in which case all the below variables will be ignored).
php_memory_limit: "256M"
php_max_execution_time: "60"
php_max_input_time: "60"
php_max_input_vars: "1000"
php_realpath_cache_size: "32K"
php_upload_max_filesize: "64M"
php_post_max_size: "32M"
php_date_timezone: "America/Chicago"
php_sendmail_path: "/usr/sbin/sendmail -t -i"
php_short_open_tag: false
php_error_reporting: "E_ALL & ~E_DEPRECATED & ~E_STRICT"
php_display_errors: "Off"
php_display_startup_errors: "On"
php_expose_php: "On"
Also, the PHP CLI environment uses the same variables as the web server by default, but you can redefine some of them with the following variables:
php_cli_memory_limit: "256M"
php_cli_max_execution_time: "60"
php_cli_max_input_time: "60"
php_cli_max_input_vars: "1000"
php_cli_realpath_cache_size: "32K"
php_cli_date_timezone: "America/Chicago"
php_cli_short_open_tag: false
php_cli_error_reporting: "E_ALL & ~E_DEPRECATED & ~E_STRICT"
php_cli_display_errors: "Off"
php_cli_display_startup_errors: "On"
php_cli_expose_php: "On"
Various defaults for PHP. Only used if php_use_managed_ini
is set to true
.
The OpCache is included in PHP starting in version 5.5, and the following variables will only take effect if the version of PHP you have installed is 5.5 or greater.
php_opcache_enabled_in_ini: false
When installing Opcache, depending on the system and whether running PHP as a webserver module or standalone via php-fpm
, you might need the line extension=opcache.so
in opcache.ini
. If you need that line added (e.g. you're running php-fpm
), set this variable to true.
php_opcache_enable: "1"
php_opcache_enable_cli: "0"
php_opcache_memory_consumption: "96"
php_opcache_interned_strings_buffer: "16"
php_opcache_max_accelerated_files: "4096"
php_opcache_max_wasted_percentage: "5"
php_opcache_validate_timestamps: "1"
php_opcache_revalidate_freq: "2"
php_opcache_max_file_size: "0"
OpCache ini directives that are often customized on a system. Make sure you have enough memory and file slots allocated in the OpCache (php_opcache_memory_consumption
, in MB, and php_opcache_max_accelerated_files
) to contain all the PHP code you are running. If not, you may get less-than-optimal performance!
php_enable_apc: true
Whether to enable APC. Other APC variables will be ineffective if this is set to false.
php_apc_enabled_in_ini: false
When installing APC, depending on the system and whether running PHP as a webserver module or standalone via php-fpm
, you might need the line extension=apc.so
in apc.ini
. If you need that line added (e.g. you're running php-fpm
), set this variable to true.
php_apc_cache_by_default: "1"
php_apc_shm_size: "96M"
php_apc_stat: "1"
php_apc_enable_cli: "0"
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 just enable it for one codebase if you have a lot of code on a server). 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).
If you use APC, you will need to make sure APC is installed (it is installed by default, but if you customize the php_packages
list, you need to include APC in the list):
- On RHEL/CentOS systems: Make sure
php-pecl-apc
is in the list ofphp_packages
. - On Debian/Ubuntu systems: Make sure
php-apc
is in the list ofphp_packages
.
You can also install APC via pecl
, but it's simpler to manage the installation with the system's package manager.
If you need a specific version of PHP, or would like to test the latest (e.g. master) version of PHP, there's a good chance there's no suitable package already available in your platform's package manager. In these cases, you may choose to install PHP from source by compiling it directly.
Note that source compilation takes much longer than installing from packages (PHP HEAD takes 5+ minutes to compile on a modern quad-core computer, just as a point of reference).
php_install_from_source: false
Set this to true
to install PHP from source instead of installing from packages.
php_source_version: "master"
The version of PHP to install from source (a git branch, tag, or commit hash).
php_source_clone_dir: "~/php-src"
php_source_install_path: "/opt/php"
Location where source will be cloned and installed, respectively.
php_source_make_command: "make"
Set the make
command to make --jobs=X
where X
is the number of cores present on the server where PHP is being compiled. Will speed up compilation times dramatically if you have multiple cores.
php_source_configure_command: >
[...]
The ./configure
command that will build the Makefile to be used for PHP compilation. Add in all the options you need for your particular environment. Using a folded scalar (>
) allows you to define the variable over multiple lines, which is extremely helpful for legibility and source control!
A few other notes/caveats for specific configurations:
- Apache with
mpm_prefork
: If you're using Apache with prefork as a webserver for PHP, you will need to make sureapxs2
is available on your system (e.g. by installingapache2-prefork-dev
in Ubuntu), and you will need to make sure the option--with-apxs2
is defined inphp_source_configure_command
. Finally, you will need to make sure thempm_prefork
module is loaded instead ofmpm_worker
ormpm_event
, and likely add aphpX.conf
(whereX
is the major version of PHP) configuration file to the Apache module config folder with contents likephp7.conf
. - Apache with
mpm_event
ormpm_worker
: If you're using Apache with event or worker as a webserver for PHP, you will need to compile PHP with FPM. Make sure the option--enable-fpm
is defined inphp_source_configure_command
. You'll also need to make sure Apache's support for CGI and event is installed (e.g. by installingapache2-mpm-event
andlibapache2-mod-fastcgi
) and thempm_event
module is loaded. - Nginx: If you're using Nginx as a webserver for PHP, you will need to compile PHP with FPM. Make sure the option
--enable-fpm
is defined inphp_source_configure_command
.
None.
