php-fpm socket + nginx

[redwood]

Hi,

I'm trying to host my own Friendica http://friendica.com/ site using the following:

• www-servers/nginx-1.2.6-r1
  
• dev-db/mariadb-5.5.29
  
• dev-lang/php-5.4.8 with fpm
  

I've followed these guides:

• http://en.gentoo-wiki.com/wiki/Nginx
  
• http://wiki.nginx.org/PlatformGentoo
  
• http://en.gentoo-wiki.com/wiki/Virtual_Webhosting_with_nginx
  
• http://www.rackspace.com/knowledge_center/article/installing-nginx-and-php-fpm-setup-for-nginx
  

I'm trying to use a unix socket instead of tcp for connecting to the fastcgi fpm, but my socket doesn't seem to get created so I'm getting a "502 Bad Gateway" error message.

[i-s-a-k]

Have you confirmed that the socket is actually created?

file /var/run/php5-fpm/fd.socket

Should return

/var/run/php5-fpm/fd.socket: socket

[redwood]

I manually created the directory /var/run/php5-fpm/
but it's empty.

The socket file /var/run/php5-fpm/fd.socket never never gets created.

When I start /etc/init.d/php-fpm
it's supposed to create the pool of sockets, right?

as specified in /etc/php/fpm-php5.4/php-fpm.conf ?

The Gentoo wiki used the tcp connection, but recommended sockets.
The rackspace setup guide said to put a socket configuration file in the pool directory:

[i-s-a-k]

And you've made sure that the nginx user has write access to /var/run/php5-fpm/ ?

[redwood]

# ls -ldn /var/run
drwxr-xr-x 20 0 0 4096 Mar 6 15:36 /var/run

# ls -ldn /var/run/php5-fpm/
drwxr-xr-x 2 124 978 4096 Mar 5 22:28 /var/run/php5-fpm/

# id nginx
uid=124(nginx) gid=978(nginx) groups=978(nginx)

[redwood]

Hmmm, there's one WARNING from php-fpm about pm.start_server not being set:

# cat /var/log/php-fpm.log

[i-s-a-k]

[www]
include=/etc/php/fpm-php5.4/pool.d/*.conf

seems like you are setting the poolname [www] before the include

that might be ok if you have only 1 pool, but if you have multiple pools that will cause some problems

[redwood]

OK, I tried moving "include" line to just before pool definition section in php-fpm.conf
Same result -- no socket created.

I've also checked out the configuration wiki
http://php-fpm.org/wiki/Configuration_File

but it's not very helpful.


/etc/init.d/php-fpm seems to start daemon as ""root and worker processes as "nobody":

[redwood]

Well,

I've been modifying the config files for php5.4-fpm
but apparently using php5.3

so I need to tell Gentoo to change PHPSLOT for fpm's init script to 5.4:

http://www.gentoo.org/proj/en/php/php-upgrading.xml

[i-s-a-k]

my point was not to move the include line

it was that [www] is the name of the pool, so if you have multiple pools

then you should include that inside the included files

for example


cat /etc/php/fpm-php5.4/pools/www.pool.conf
[www]
listen = /var/run/www_fpm.sock
pm = dynamic
pm.start_servers = 1
.... etc


cat /etc/php/fpm-php5.4/pools/www2.pool.conf
[www2]
listen = /var/run/www2_fpm.sock
pm = dynamic
pm.start_servers = 1
.... etc



anyway good that you got it working

[redwood]

Thanks for the help!


I've got a regular LAMP server on another machine.
I was going to setup mariadb+nginx in an lxc container
but I think my kernel (3.3. is too new for lxc
lxc-start kept complaining about a missing kernel option
that's been removed from the current kernel's makefile.

So I'm just setting this up on main host.

Haven't yet got Friendica working.
Just getting a blank screen which probably means there some missing php module
that I haven't yet tracked down.

Friendica supplies a virtualbox image but I was trying to see if I could just
install the webapp and the database
without running virtualbox.

Anybody hosting their own friendica?

[redwood]

Fixed my blank screen issue.

Somehow I deleted or didn't cut-n-paste the first line
of /etc/nginx/fastcgi_params:

which should have been:
