Instalasi Nginx dari Source

Baca Instalasi Nginx dari Source di Ubuntu Hardy.

Instalasi PHP dan MySQL

Kita akan menginstal php5-cgi, karena PHP akan dipanggil melalui modul FastCGI di nginx. Instalasi paket:

sudo apt-get install php5-cgi php5-mysql mysql-server

Jika memerlukan, Anda bisa juga menginstal modul php yang lain. Untuk melihat daftar modul php5 yang ada di repo ubuntu.

apt-cache search php5-

Skrip PHP sebagai FCGI

Tidak seperti Apache atau Lighttpd, Nginx tidak secara otomatis menjalankan proses FCGI. Anda harus menjalankannya secara terpisah. Ada banyak cara untuk menjalankan program FCGI untuk php, tapi yang akan dijelaskan dibawah ini adalah menjalankan PHP dalam mode FCGI server.

Yang perlu Anda buat adalah dua berkas, /etc/default/php-fastcgi dan /etc/init.d/php-fastcgi. Contoh filenya bisa dilihat di bawah ini.

/etc/default/php-fastcgi

 Berkas: /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=9000

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

/etc/init.d/php-fastcgi

 Berkas: /etc/init.d/php-fastcgi
#! /bin/bash

Jalankan PHP FastCGI otomatis saat booting

Untuk menjalankan php dalam mode FastCGI, Anda tinggal mengeksekusi skrip di atas.

sudo /etc/init.d/php-fastcgi start

Dan untuk memastikan skrip ini dijalankan waktu booting, gunakan perintah berikut:

sudo update-rc.d php-fastcgi defaults

Konfigurasi Nginx

Contoh konfigurasi di nginx (tidak lengkap, ini hanya menuliskan bagian virtual host nya saja).

 Berkas: nginx.conf
server {
        listen          80;
        server_name     localhost;

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                 root           html;
                 fastcgi_pass   127.0.0.1:9000;
                 fastcgi_index  index.php;
                 fastcgi_param  SCRIPT_FILENAME  /var/www/phpmyadmin$fastcgi_script_name;
                 include        fastcgi_params;
        }

        location / {
                root /var/www/phpmyadmin;
                index index.php;
        }
}
