different php.ini settings for various virtualhost (php-fpm)

Question

I searched allot here on serverFault and found this solution...

Including this in virtual host should work:

  php_admin_flag register_argc_argv = On
  php_value max_execution_time = 1000
  php_value session.gc_maxlifetime = 15000
  php_admin_flag magic_quotes_gpc = on

But than it dawned me, I'm not using mod_php at all. I have php-fpm installed. And I really cannot find any information if my method will work, or if there is an alternative way...

So, what do I do if I've php-fpm and would like to have different settings for virtualhost?

Answer 1

On php-fpm, you usually set this in the fpm pool of the domain. The pools are included from php-fpm's main conf-file, which is located on my server at /etc/php/fpm-php5.3/php-fpm.conf:

...

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ; 
;;;;;;;;;;;;;;;;;;;;

include=/var/www/*/conf/fpm-pool.conf

In the fpm-pool-config, you can set php_admin_flag and php_admin_value like this:

...

;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'. 
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
php_flag[display_errors]            = on
php_admin_value[error_log]          = /var/www/cloud/logs/php_err.log
php_admin_flag[log_errors]          = on
php_admin_value[memory_limit]       = 1024M
#php_value[max_execution_time]       = 30
php_admin_value[upload_max_filesize] = 4G
php_admin_value[post_max_size]      = 4.2G
php_admin_value[max_input_time]     = 3600
php_admin_value[max_execution_time] = 3600

Answer 2

I had a RAM-hungry server and wanted to avoid configuring multiple pools for each of the low-traffic sites I was running. I also didn't like the security concerns of directory-based .user.ini’s, so I implemented a different solution using php.ini "sections":

http://php.net/ini.sections

You can define sections of php.ini (in my case, /etc/php5/fpm/php.ini) that are either path, or host, specific. At the bottom, I have:

[HOST=host1.example.com]
auto_prepend_file = '/var/www/something'

[HOST=host2.example.net]
upload_max_filesize = 5M

I read elsewhere that if you use the host method, you must use the specific value defined in ServerName in the VirtualHost config, not any of the aliases.

P.S. This was all done on Debian Jessie 8.4

Answer 3

You can include these flags in an .htaccess file under each virtual host that you want these settings. See: http://www.php.net/manual/en/configuration.file.per-user.php

Answer 4

For nginx use this solution:

Since PHP 5.3.3 you can use this command in your nginx-vhost-file.

Example for setting the maxlifetime of sessions:

server {
    listen 80;
    listen [::]:80;

    ...

    location ~ \.php$ {
        ...

        fastcgi_param PHP_VALUE "session.gc_maxlifetime=604800";
        fastcgi_param PHP_VALUE "session.cookie_lifetime=604800";
    }
}
