My server runs Cloudlinux 5.11 with CageFS and PHP Selector. Default PHP version is 5.3.

I have one account using PHP 5.3, one account using PHP 5.5, and one account using PHP 5.6.

I'm trying to figure out how to update each account's php.ini or each PHP version's default php.ini.

So far I've figured out how to update PHP 5.3's default php.ini:

  1. phpinfo on the PHP 5.3 account shows the loaded configuration file is from /usr/selector.etc/php.ini.

  2. Update /usr/local/lib/php.ini

  3. Run cagefsctl --force-update

  4. Rebuild Apache

Then the modified /usr/local/lib/php.ini is reflected on the phpinfo.

However, for PHP 5.5. and 5.6 accounts, I can't figure out how to update their default php.ini's.

  1. Their phpinfo shows the loaded configuration files are from /opt/alt/php55/etc/php.ini and /opt/alt/php56/etc/php.ini

  2. Update those files

  3. Run cagefsctl --force-update

  4. Rebuild Apache

Afterwards, the changes of these php.ini's are reverted! So where is the right place to change these PHP versions' default php.ini's?

Being able to update each PHP version's default php.ini would work for me, but it would be even easier and more flexible if each domain account (or even each folder) can have its own php.ini.

I've tried /public_html/php.ini and /public_html/.htaccess. They don't take effect at all. ini_set in script works though, but of course I don't want to reply on just ini_set.

  • Are the ini files, or the folder they're in, symbolic links? Commented Mar 5, 2016 at 22:26
  • All the files I mentioned here are not symbolic links. Thanks.

Found the answer. For alternative PHP versions, the process is different.

After modifying /opt/alt/phpXX/etc/php.ini

Run cagefsctl --rebuild-alt-php-ini

That's it. No need to rebuild apache.
