Plesk 11.5 Debian/Ubuntu PHP5.4

[Janko1000]

Hello,

is there a guide on how to safely install PHP5.4 on Debian / Ubuntu Plesk 11.5?

None that I know of. But this should be pretty straightforward - update PHP to 5.4 from third-party repository as you normally would. The only thing you should care about is to not remove any of Plesk packages during the process (but I won't expect this to happen).

After the upgrade is complete you may want to call:
# plesk sbin packagemng -sdf
# service apache2 restart

If you already had php-fpm, also restart it. Also manually check that your old php.ini is compatible with the new version (e.g., leaving safe_mode=on there will bring you grief).


Alternative way is to use custom php handlers feature (i.e., build and install you own PHP and register it in Plesk). But I'd stick to the first option unless you need 2 different PHP versions.
