In the default configuration before 12.10 Quantal, PHP FPM is set to listen on TCP port 9000 on address This can be changed in /etc/php5/fpm/pool.d/www.conf.

Look for the line:

listen =

and change it to something like:

listen = /var/run/php5-fpm.sock

After doing so, restart PHP FPM:

sudo /etc/init.d/php5-fpm restart

(note: reload is broken on Oneiric as it sends a HUP signal to php5-fpm which is wrong. It's fixed in Precise by sending USR2, bugreport).

Note: as mentioned by @SpamapS (palingdrome :D), newer releases use Unix sockets by default, not the tcp socket. See this Launchpad comment, it got changed in 12.10 Quantal.

  • Just a note, on precise, php5-fpm actually runs on a socket by default. ;)

    @SpamapS I don't think so, the changelog does not mention anything. Just to be sure, I checked the php5-fpm .deb package for version 5.3.10-1ubuntu3 and it still contains listen = Perhaps you've previously changed this and upgraded while keeping the conffiles?

    Well no, I submitted the change to Debian, and they merged it, but only to the PHP 5.4 packages. I actually mistakenly set the bug status on pad.lv/900620 , so thanks for the heads up, set it back to Triaged. We'll pick it up on the next merge from Debian.

  • In 14.04, it appears to use a UNIX socket by default, so things must have changed. Apr 30, 2014 at 9:47

Unfortunately this method is old and will no longer work . OLD

sudo /etc/init.d/php5-fpm restart

Now a days you need to use

sudo service php5-fpm restart

In place of restart you may also use; start, stop and reload.
