NginX

PHP FPM

PHP is not integrated into NginX but it runs as a standalone process. PHP-FPM controlls that process.

Ubuntu 12.04

#apt-get install php5-common php5-cli php5-fpm

#php5 -v

PHP 5.3.10-1ubuntu3.16 with Suhosin-Patch (cli) (built: Feb 13 2015 20:15:22)

If you want upgrade to PHP5.5 do the following:

a) # apt-get install python-software-properties (ako već nije instaliran pri upgradeu nginX-a)
b) # add-apt-repository ppa:ondrej/php5
c) # apt-get update
d) # apt-get dist-upgrade
e) sada # php --version daje

PHP 5.5.12-2+deb.sury.org~precise+1 (cli) (built: May 12 2014 13:46:35)

PHP-FPM (FastCGI Process Manager)

$sudo service php5-fpm start

$sudo service php5-fpm restart

$sudo service php5-fpm stop

By default PHP-FPM is using TCP connection 127.0.0.1:9000 to NginX or other processes.

To change this edit /etc/php5/fpm/pool.d/www.conf file

Instead of

listen = 127.0.0.1:9000

put

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

Sockets are faster but sockets are only reachable from programs that are running on the same server.

NGINX VIRTUAL HOST CONFIG

}

Errors

1. When we are using php-fpm socket error 502 Bad gateway can occur

log file ---> connect() to unix:/var/run/php5-fpm.sock failed (13: Permission denied)

SOLUTION:

a) uncoment lines in /etc/php5/fpm/pool.d/www.conf

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

b) check if the user is www-data in /etc/nginx/nginx.conf

user www-data;

c) restart nginx and php-fpm

#service nginx restart

#service php5-fpm restart
