How can I increase PHP memory limit in Plesk?

Question

A client has given me a Plesk account to install his PHP app in, but the PHP memory limit is only 32M and I'd like to increase it. I tried to find this setting on the admin panel but couldn't :(

Answer 1

You may adjust that value via .htaccess file.

php_value memory_limit 64M

Answer 2

There is no way to update it on the control panel.

What you need to do is to create a file called : vhost.conf

This file must be located in :

/var/www/vhosts/domain.com/conf/

Inside this file, add (and change domain.com) :

<Directory /var/www/vhosts/domain.com/httpdocs/>
php_value memory_limit 64M
</Directory>

As root, run the following :

/usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=domain.com

Restart Apache

Please note that if you use Fast-CGI this won't work, you would need to change it within the main php.ini.

EDIT: Added path to vhost.conf file

Answer 3

I don't know if your admin panel allows you to access this file, but the usual way to increase PHP memory limit is by changing the memory_limit option in the php.ini file.

Answer 4

I use plesk 10 on my own shared Linux server and this works:

ini_set('memory_limit', '64M');

Makes life easy because you can just do it where a script really should take up lots of RAM. Might need some changes depending on your server but for me it runs out of the box.
