Changing PHP Settings
PHP settings are controlled using php.ini files. When you deploy a server via SpinupWP, a default php.ini file is created with sensible default values. However, you are free to update these values.
Each version of PHP has its own php.ini file, which is located here:
/etc/php/{PHP_VERSION}/fpm/php.ini
Any changes made to this file will impact all sites on the server running that version of PHP, unless they are overridden by per-site settings. After you’ve made the desired configuration changes, you must reload PHP for the changes to take effect.
sudo service php{PHP_VERSION}-fpm reload
Per-Site Settings
Each site deployed via SpinupWP is created with it’s own PHP pool. This means that you can override the settings in your php.ini file on a per-site basis. Any value in your php.ini file can be overridden by adding the value to your /etc/php/{PHP_VERSION}/fpm/pool.d/{SITE_USER}.conf file, like so:
php_value[upload_max_filesize] = 64M
php_value[post_max_size] = 64M
php_value should not be used to set boolean values. Instead, use php_flag:
php_flag[display_errors] = Off
It’s also possible to prevent config values from being overridden by ini_set by using php_admin_value and php_admin_flag.
php_admin_value[upload_max_filesize] = 64M
php_admin_value[post_max_size] = 64M
php_admin_flag[display_errors] = Off
Remember to reload PHP when making any changes to your PHP pool config files.
sudo service php{PHP_VERSION}-fpm reloadArray Based Syntax
Note that per-site configuration files use array based syntax. This is a slightly different syntax than found in default php.ini files.
Setting the upload_max_file_size in a per-site file:
php_value[upload_max_filesize] = 64MSetting the upload_max_file_size in a default php.ini file:
upload_max_filesize = 64M
