If you are a relatively new Linux user and you manage a server with PHP, it is important that you know that after editing the php.ini file , you must restart the PHP service.
PHp is associated with your web server or with your external FastCGI process manager. In most cases, after editing the php.ini file , you only need to restart your server, which is probably Apache, Nginx or Lighttpd, depending on what you have installed on your operating system. In this way you can apply the new saved configuration .
We will see how to restart PHP, for which, you must restart your web server. Depending on your web server, you must execute one of the following commands:
Restart Apache to restart PHP
If you use Apache, type the following command:
# /etc/init.d/apache2 restart
Or also:
# apache2ctl restart
Or also, with the service command:
# service apache2 restart
If you use CentOS, the server will have the name of httpd instead of Apache2:
# service httpd restart
Restart Nginx to restart PHP
If you use the Nginx web server, type the following command to restart it:
# /etc/init.d/nginx restart
You can also use the service command:
# service nginx restart
Or also this command:
# nginx -s reload
Restart Lighttpd to restart PHP
If you use the Lighttpd web server, type the following command to restart it:
# /etc/init.d/lighttpd restart
Or also:
# service lighttpd restart
Restart PHP-FAM FastCGI to restart PHP
If you use PHP from the PHP-FAM fastcgi manager , use one of the following commands. Depending on your version of Linux, it may be one or the other:
# /etc/init.d/php-fpm restart
For PHP5 you can also run:
# /etc/init.d/php5-fpm restart
Or also:
# service php-fpm restart
Or also:
# service php5-fpm restart
And finally you can also try:
# restart php-fpm
