how to configure php as fastcgi on nginx

  1. install php
    user@computer:$ sudo apt-get install php5-cgi
  2. buat file /etc/default/php-fastcgi
    user@computer:$ sudo vim /etc/default/php-fastcgi
    START=yes

    # Which user runs PHP? (default: www-data)
    EXEC_AS_USER=www-data

    # Host and TCP port for FASTCGI-Listener (default: localhost:9000)
    FCGI_HOST=localhost
    FCGI_PORT=8888

    # Environment variables, which are processed by PHP
    PHP_FCGI_CHILDREN=4
    PHP_FCGI_MAX_REQUESTS=1000

  3. buat file /etc/init.d/php-fastcgi
    user@computer:$ sudo vim /etc/init.d/php-fastcgi
    #! /bin/bash

    do_start()
    {
    # Return
    #   0 if daemon has been started
    #   1 if daemon was already running
    #   2 if daemon could not be started
    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \
    || return 1

    [ "$RETVAL" = 2 ] && return 2
    # Wait for children to finish too if this is a daemon that forks
    # and if the daemon is only ever run from this initscript.
    # If the above conditions are not satisfied then add some other code
    # that waits for the process to drop all resources that could be
    # needed by services started subsequently.  A last resort is to
    # sleep for some time.
    start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON

    rm -f $PIDFILE
    return "$RETVAL"
    }

    case "$1" in
    start)

    echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
    exit 3
    ;;
    esac
  4. setting permission agar bisa dieksekusi
    user@computer:$ sudo chmod 755 /etc/init.d/php-fastcgi
  5. contoh konfigurasi vhost
    user@computer:$ sudo less /etc/nginx/sites-available/sarunkgenk.com
    server {
    listen      *:80;
    server_name  sarunkgenk.com www.sarunkgenk.com *.sarunkgenk.com;
    access_log /var/log/nginx/access_sarunkgenk.log;
    error_log /var/log/nginx/error_sarunkgenk.log;
    location ~* ^.+\.(html|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ {
    root /home/arditto/wordpress-mu/;
    expires 30d;
    break;
    }
    location / {
    root   /home/arditto/wordpress-mu/;
    index  index.php index.html index.htm;
    if (!-e $request_filename) {
    rewrite ^.+/?(/wp-.*) $1 last;
    rewrite ^.+/?(/.*\.php)$ $1 last;
    rewrite ^(.+)$ /index.php?q=$1 last;
    }

    fastcgi_pass   127.0.0.1:8888;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME /home/arditto/wordpress-mu$fastcgi_script_name;
    include        /etc/nginx/fastcgi_params;
    }
    }
  6. jalankan php dalam mode fastcgi
    user@computer:$ sudo /etc/init.d/php-fastcgi start
  7. supaya proses no 6 dijalankan otomatis saat booting, jalankan perintah :
    user@computer:$ sudo update-rc.d php-fastcgi defaults
