I'm setting up a server with nginx + php-fpm (5.4.11) on ubuntu 12.04 LTS (x64)

I installed nginx from the repository and I compiled PHP myself. Everythings work fine when I start php-fpm and nginx

sudo /etc/init.d/php-5.4.11-fpm start
sudo service nginx start

I can display a phpinfo on a webpage, so far so good.

pid is set like this in /etc/php-5.4.11/php-fpm.conf

pid = /var/run/php-5.4.11/

and from /etc/nginx/sites-available/default

location ~ \.php$ {
  fastcgi_split_path_info ^(.+\.php)(/.+)$;
  fastcgi_pass unix:/var/run/php-5.4.11/php-fpm.sock;
  fastcgi_index index.php;
  include fastcgi_params;

Now, I would like to start PHP when the server reboots, so I did:

update-rc.d php-5.4.11-fpm defaults

But when I restart the server, I got this error in the log file:

ERROR: unable to bind listening socket for address '/var/run/php-5.4.11/php-fpm.sock': No such file or directory (2)

And indeed, the directory that I created myself /var/run/php-5.4.11/ has disappeared. If I create it again and do sudo /etc/init.d/php-5.4.11-fpm start, it works. But If I restart the server, the directory will be deleted and php-fpm won't start.

What's wrong, I don't get it? Thank you very much!

Probably, tmpfs is mounted to the /var/run. In other words, this is a RAM-disk and it's clean at OS start.

In this case you should point "pid" and "listen" directives of your php-fpm pool configuration straight to the /var/run:

pid = /var/run/

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

Thank you, it works! – JuCachalot Feb 11 '13 at 18:06
I wonder if this work if you have multiple vhosts? What happens when they share the same path to sock and pid? – mr1031011 Nov 3 '13 at 9:05
