In this tutorial i will try to install php-fpm with nginx on centos 5.3. But first:

What is PHP-FPM ?

PHP-FPM is a patch for PHP4/5 to greatly improve PHP’s FastCGI SAPI capabilities and administration. This means that you don’t install php through your distribution’s package manager, but rather download the package from the PHP-website, and the patch from another site. You patch up the sourcecode, compile things, and get it started.

The following is a comparison chart of problems and how php-fpm handles them, when enabled with the FastCGI SAPI:

Description php “out of the box” spawn-fcgi + spawn-php.sh + daemontools php-fpm
php daemonization: pid file, log file, setsid(), setuid(), setgid(), chroot() (-) (+) (+)
Process Management. Ability to “graceful” stop and start php workers without losing any queries. The possibility of gradually update the configuration and binary without losing any queries. php4 (-), php5 (only graceful completion) (-) (+)
Restricting ip addresses from which requests can come from a web server php4 (-), php5 (+) (from 5.2.2) (-) (+)
Dynamic number of processes, depending on the load (-) (-) TODO
Starting the workers with different uid/gid/chroot/environment and different php.ini option. You do not need a safe mode! (-) (-) (+)
Logging stdout & stderr business processes (-) (-) (+)
Emergency restart all the processes in the event of accidental destruction of shared memory opcode cache, if used accelerator (-) (-) (+)
Forcing the completion of process if set_time_limit() fails (-) (-) (+)

Compare to spawn- fastcgi installation , php-fpm installation is much slower and you can refer to http://www.cyberciti.biz/faq/rhel-fedora-install-configure-nginx-php5/ for spawn-fcgi installation. Okay let’s start the installation.

Installation

1. Install some dependecies first
# yum install gcc libjpeg-devel libpng-devel libmcrypt libmcrypt-devel pcre pcre-devel

2. We need to get PHP-sourcecode and php-fpm patch, in this tutorial i use php-5.2.10 and php-5.2.10-fpm-0.5.13
# wget http://id.php.net/get/php-5.2.10.tar.bz2/from/us.php.net/mirror
wget http://php-fpm.org/downloads/php-5.2.10-fpm-0.5.13.diff.gz

3. Extract and run the patch
# tar xvf php-5.2.10.tar.bz2
# gzip -cd php-5.2.10-fpm-0.5.13.diff.gz | patch -d php-5.2.10 -p1

4. Configure and compile cd php-5.2.10 and hp-5.2.10-fpm-0.5.13 patch
# ./configure --enable-fastcgi --enable-fpm --with-mcrypt --enable-mbstring --enable-mysql --with-mysql=/usr/include/mysql --with-mysql-sock=/tmp/mysql.sock --with-curl --with-sockets --with-gd --with-zlib --with-iconv --with-dom --with-jpeg-dir=/usr/lib
make
make install

You should see this on the end of installation

Installing PEAR environment: /usr/local/lib/php/
pear/pear dependency package "pear/Archive_Tar" installed version 1.3.3 is not the recommended version
1.3.2, but may be compatible, use --force to install
pear/Archive_Tar cannot be installed, conflicts with installed packages

You may want to add: /usr/local/lib/php to your php.ini include_path
Installing PDO headers: /usr/local/include/php/ext/pdo/

5. Installing Init Script for PHP-FPM
# cd /etc/init.d/
# ln -s /usr/local/sbin/php-fpm php-fpm

add this to /etc/rc.local if you want php-fpm to start from booting
# vi /etc/rc.local
/etc/init.d/php-fpm start

6. Installing and configure nginx, when i write this tutorial the latest stable versions are nginx-0.7.61 you can go to http://nginx.net/ for latest nginx sourcode
wget http://sysoev.ru/nginx/nginx-0.7.61.tar.gz
tar xvf http://sysoev.ru/nginx/nginx-0.7.61.tar.gz
cd nginx-0.7.61
./configure --pid-path=/usr/local/nginx/logs/nginx.pid --sbin-path=/usr/local/sbin/nginx --with-md5=/usr/lib --with-sha1=/usr/lib --with-http_ssl_module --with-http_dav_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module
# make
# make install

7. Installing Nginx Daemon for CentOS, you can copy paste this script to your /etc/init.d/nginx

#! /bin/sh
### BEGIN INIT INFO
# Provides: skeleton
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Default-Start: 2 3 4 5
# Default-Stop: S 0 1 6
# Short-Description: Example initscript
# Description: This file should be used to construct scripts to be
# placed in /etc/init.d.
### END INIT INFO
#
# Author: Ryan Norbauer
#
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="nginx daemon"
NAME=nginx
DAEMON=/usr/local/sbin/$NAME
PIDFILE=/usr/local/nginx/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
# Read config file if it is present.
#if [ -r /etc/default/$NAME ]
#then
# . /etc/default/$NAME
#fi
#
# Function that starts the daemon/service.
#
d_start() {
start-stop-daemon --start --quiet --pidfile $PIDFILE \
--exec $DAEMON \
|| echo -n " already running"
}
#
# Function that stops the daemon/service.
#
d_stop() {
start-stop-daemon --stop --quiet --pidfile $PIDFILE \
--name $NAME \
|| echo -n " not running"
}

#
# Function that sends a SIGHUP to the daemon/service.
#
d_reload() {
start-stop-daemon --stop --quiet --pidfile $PIDFILE \
--name $NAME --signal 1
}

case "$1" in
start)
echo -n "Starting $DESC: $NAME"
d_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
d_stop
echo "."
;;
#reload)
#
# If the daemon can reload its configuration without
# restarting (for example, when it is sent a SIGHUP),
# then implement that here.
#
# If the daemon responds to changes in its config file
# directly anyway, make this an "exit 0".
#
# echo -n "Reloading $DESC configuration..."
# d_reload
# echo "done."
#;;
restart|force-reload)
#
# If the "reload" option is implemented, move the "force-reload"
# option to the "reload" entry above. If not, "force-reload" is
# just the same as "restart".
#
echo -n "Restarting $DESC: $NAME"
d_stop
# One second might not be time enough for a daemon to stop,
# if this happens, d_start will fail (and dpkg will break if
# the package is being upgraded). Change the timeout if needed
# be, or change d_stop to have start-stop-daemon use --retry.
# Notice that using --retry slows down the shutdown process somewhat.
sleep 1
d_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
exit 3
;;
esac
exit 0

Or you can download it from http://www.magnet-id.com/download/nginx/nginx-daemon
wget http://www.magnet-id.com/download/nginx/nginx-daemon -O /etc/init.d/nginx
and don’t forget to set the permission
# chmod 750 /etc/init.d/nginx

Install start-stop-daemonvand add nginx on the start up

wget http://www.magnet-id.com/download/nginx/apps-sys-utils-start-stop-daemon-IR1_9_18-1.tar.gz
tar zxvf apps-sys-utils-start-stop-daemon-IR1_9_18-1.tar.gz
cd apps/sys-utils/start-stop-daemon-IR1_9_18-1/
gcc start-stop-daemon.c -o start-stop-daemon
cp start-stop-daemon /usr/sbin
chkconfig --add nginx
chkconfig --level 345 nginx on

Nginx.conf configuration

go to nginx configuration file: “/usr/local/nginx/conf/nginx.conf” , and add the php configuration

location ~ \.php$ {
root /usr/share/nginx/html; # itmena the root of the coument are located on /usr/share/nginx/html
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}

Go to /usr/share/nginx/html and create php files
# vi index.php
<? phpinfo(); ?>

8. Start the nginx and php-fpm
# service php-fpm start
# service nginx start
9. You should go to your domain or server address and see the phpinfo
