Linux php ini reload

Find the correct php.ini file

I am currently trying to locate the correct php.ini file to edit it and restart apache so the changes will take place and I’m stumped. I have found three different php.ini files (no idea why there are three) this is how I found the files

$ sudo find / -name php.ini /etc/php5/cli/php.ini /etc/php5/apache2/php.ini /etc/php5/cgi/php.ini 

$ sudo php -i | grep 'Configuration File' Configuration File (php.ini) Path => /etc/php5/cli Loaded Configuration File => /etc/php5/cli/php.ini 

sudo service apache2 restart 

* Restarting web server apache2 

echo ini_get('post_max_size'); 

Which was supposed to be changed to 20M but was still only 2M I tried rebooting my computer thinking maybe that would stop the apache server and reload the php.ini file with the correct setting, but alas that attempt also failed. Is there any chance there could be another php.ini file that could be interfering?

@Michael The file is /etc/php/5.6/apache2/php.ini in Ubuntu 16.04 LTS Xenial Xerus, where 5.6/ is the version of php installed. First copy the file to php.original.ini then open for editing with sudo gedit /etc/php/5.6/apache2/php.ini

The three files you have there are each meant for different uses.

/etc/php/5.6/cli/php.ini is for the CLI PHP program, which you found by running php on the terminal.

/etc/php/5.6/cgi/php.ini is for the php-cgi system which isn’t specifically used in this setup.

/etc/php/5.6/apache2/php.ini is for the PHP plugin used by Apache. This is the one you need to edit for changes to be applied for your Apache setup which utilizes the in-built PHP module to Apache.

/etc/php/5.6/fpm/php.ini is for the php5-fpm processor, which is a fastcgi-compatible ‘wrapper’ for PHP processing (such as to hand off from NGINX to php5-fpm ) and runs as a standalone process on the system (unlike the Apache PHP plugin)

For versions of Ubuntu lower than 16.04, /etc/php/5.6/ , /etc/php/7.0/ , /etc/php/7.1/ , and so on, are replaced by /etc/php5/ and so on. Otherwise, these paths remain accurate. Adapt this accordingly for your environment, replacing the 5.6 or number with the actual version folder that exists on your environment.

How to force reloading php.ini file?

I configured a web server last week, it worked fine. Today I request its homepage, I see a timezone error, as it should be configured into my php.ini file. I try a phpinfo(); on my webserver, it gives me:

Configuration File (php.ini) Path /opt/rrh/php/lib 

 ls -la /opt/rrh/php/lib -rwxrwxrwx 1 apache root 68448 Nov 22 10:10 php.ini

TL;DR; If you’re still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don’t always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I’ve taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn’t trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart # typical /etc/init.d/php5-fpm restart # debian-style /etc/init.d/php7.0-fpm restart # debian-style PHP 7 

Using service wrapper script

service php-fpm restart # typical service php5-fpm restart # debian-style service php7.0-fpm restart. # debian-style PHP 7 

restart php7.0-fpm # typical (ubuntu is debian-based) PHP 7 restart php5-fpm # typical (ubuntu is debian-based) restart php-fpm # uncommon 

Using systemd (newer servers):

systemctl restart php-fpm.service # typical systemctl restart php5-fpm.service # uncommon systemctl restart php7.0-fpm.service # uncommon PHP 7 

Or whatever the equivalent is on your system.

Do I need to restart Apache after changing the php.ini file?

If I make a change to a setting in the php.ini file — do I need to restart Apache in order for it to take effect?

Depends, actually. Depends on how you use php inside that webserver:

• using php as module inside the http server: you have to restart the http server process
• using php as cgi backend: you do not have to restart the http server process or anything else
• using php fastcgi: you have to restart the fastcgi daemon, not the http server
• using php-fpm: you have to restart the fpm server process, not the http server process

PHP-FPM you need to restart to avoid configuration inconsistency. Some workers will lay dormant and keep the old configuration, while new workers will get the new configuration.

@osullic Certainly go and as your question, that is what this site is for, isn’t it? 😉 But before asking. what do you actually mean by «PHP is used»? Sounds trivial at first, but is it? How would you say that assertion is true for a given http server, when?

On Debian 8 I had to restart PHP-FPM (and Apache) The above answers are correct, but here are the commands so you won’t have to googling them.

sudo service php5-fpm restart 

That depends on the SAPI you’re using. If you’re using PHP as an Apache module for example, you need to restart apache so that the php.ini values take effect.

If you’re using FCGI, you need to restart the FCGI daemon for the PHP script that you want to see the values changed. Compare with

It depends on what OS and version you are running.

I am running Apache/2.4.29 under Ubuntu.

I restart apache with the following command and the restart is needed after modifying the php.ini file:

sudo service apache2 restart 

Not sure about Apache but on Windows with IIS a restart is not required.

Either way, considering the myriad of different configurations out there with PHP, an easy way to check is to load your phpinfo.php file in a browser and confirm the value of a setting, then change that setting in php.ini and reload phpinfo.php to see if it’s picking up your change.

although its not helpful with apache, saying that it is not needed in iis is ONLY correct if the ini-file is monitored by iis
