What is PHP-FPM?FastCGI Process Manager for PHP
Another Russian guy, who wasn't satisfied with existing PHP FastCGI, and has created FPM in his spare time
In PHP core since 5.5.3

Classic LAMP vs nginx + PHP-FPM
LAMP One Apache process per each connection
PHP is compiled into Apache and launches again on every request
High memory and CPU consumption in a high load environment
nginx + PHP-FPM A few nginx processes handle thousands of connections
PHP processes are spawned when necessary; already spawned ones are reused
Low memory and CPU consumption
Installing nginx
wget http://nginx.org/download/nginx-0.9.4.tar.gztar -xzf nginx-0.9.4.tar.gzcd nginx-0.9.4./configure --with-http_ssl_module ...makemake install
Create init script in /etc/init.d/nginx
Installing PHP-FPM
wget http://www.php.net/get/php-5.3.5.tar.gztar -xzf php-5.3.5.tar.gzcd php-5.3.5 ./configure --enable-fpm --with-mysql --with-mcrypt --with-curl --with-mysqli --with-mysql-sock --with-pdo-mysql --with-gd --with-zlibmakemake install
Create init script in /etc/init.d/php-fpm
Configuring nginx
less /usr/local/nginx/conf/nginx.confuser www-data;worker_processes 1;
error_log /var/log/nginx/error.log;pid /var/run/nginx.pid;
events { worker_connections 1024;}
http { include mime.types; default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
gzip on;
include /usr/local/nginx/sites-enabled/*;
}
The add and remove PHP scripts
addclient.php:Creates Linux user with auto generated passwordWrites Nginx configuration fileWrites FPM configuration fileCreates a placeholder web page for the new userCreates MySQL user and database
remclient.php:Reverse action – removes everything including user dir
Creating Linux userThe PHP script:•Generates a random password•Makes sure that user name and domain names are correct (RegEx)•Sends command to create the user
// Creating Unix user, default group www-datapassthru("useradd -m -K UMASK=027 -s /bin/bash -c '$domain' -p $passwordCrypted $username", $res);passthru("usermod -a -G $username www-data");
•In the end script checks whether the user was created successfully or not
Generating Nginx and FPM configs
The PHP script:
•Uses pre-written templates for both configs, replacing username and domain info
•Copies the config files into nginx available-sites and fpm config directory
•Creates a link into Nginx sites-enabled
Configuring nginx - vhost template
less ~/hostadmin/nginx_tpl.txtserver { listen 80; server_name [[domain]]; root /home/[[user]]/www/; access_log /home/[[user]]/logs/access.log; error_log /home/[[user]]/logs/error.log; location / { try_files $uri $uri/ @rewr;
index index.html index.php; } location ~ \.php$ { include /usr/local/nginx/conf/fastcgi.conf; fastcgi_pass unix:/tmp/[[user]].sock; fastcgi_index index.php; } location @rewr { rewrite ^/(.*)$ /index.php?q=$1 last; }}
Configuring PHP-FPM - vhost template
less ~/hostadmin/fpm_tpl.txt[[[user]]]
listen = /tmp/[[user]].sock
user = [[user]]group = [[user]]
pm = dynamicpm.max_children = 50pm.start_servers = 1pm.min_spare_servers = 1pm.max_spare_servers = 35
php_admin_value[error_log] = /home/[[user]]/logs/fpm-php.log
Creating a placeholder web page
The PHP script:
•Uses pre-written HTML and replacing user name and domain name
•Copies the new HTML file into user’s www directory
•Sets permissions
Creating the MySQL database
The PHP script uses three simple MySQL:
Create database:
mysql_query("create database $user")
Create user with generated password and all privileges to his/her database:
mysql_query("grant all privileges on $user.* to $user@localhost identified by '$pass'")
