Membuat Server dengan PHP dan Nginx

Apa itu Nginx versi Wikipedia :

nginx (pronounced “engine-x”) is a lightweight, high-performance Web server/reverse proxy and e-mail (IMAP/POP3) proxy, licensed under a BSD-like license. It runs on Unix, Linux, BSD variants, Mac OS X, Solaris, andMicrosoft Windows.

Nginx quickly delivers static content with efficient use of system resources. It can deploy dynamic HTTP content on a network using FastCGI handlers forscripts, and can serve as a very capable software load balancer.^[2]

Nginx uses an asynchronous event-driven approach to handling requests which provides more predictable performance under load, in contrast to theApache HTTP server model that uses a threaded or process-oriented approach to handling requests.^[3]

Step by step :

1. Tambah repo :

$ add-apt-repository ppa:nginx/$nginx

2. Trz update :

$ sudo apt-get update

3. Trz install Nginx :

$ sudo aptitude install nginx

4. Trz install paket php yg d’perlukan (seperti php5-cgi) :

$ sudo aptitude install php5-cgi

Bsa jg menambahkan yg lain seperti

$ apt-get php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

5. Create PHP 5 FastCGI start-up script :

$ sudo nano /etc/init.d/php-fastcgi

Dan masukkan script ini :

#!/bin/bash
BIND=127.0.0.1:9000
USER=www-data
PHP_FCGI_CHILDREN=15
PHP_FCGI_MAX_REQUESTS=1000

PHP_CGI=/usr/bin/php-cgi
PHP_CGI_NAME=`basename $PHP_CGI`
PHP_CGI_ARGS="- USER=$USER PATH=/usr/bin PHP_FCGI_CHILDREN=$PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=$PHP_FCGI_MAX_REQUESTS $PHP_CGI -b $BIND"
RETVAL=0

start() {
      echo -n "Starting PHP FastCGI: "
      start-stop-daemon --quiet --start --background --chuid "$USER" --exec /usr/bin/env -- $PHP_CGI_ARGS
      RETVAL=$?
      echo "$PHP_CGI_NAME."
}
stop() {
      echo -n "Stopping PHP FastCGI: "
      killall -q -w -u $USER $PHP_CGI
      RETVAL=$?
      echo "$PHP_CGI_NAME."
}

case "$1" in
    start)
      start
  ;;
    stop)
      stop
  ;;
    restart)
      stop
      start
  ;;
    *)
      echo "Usage: php-fastcgi {start|stop|restart}"
      exit 1
  ;;
esac
exit $RETVAL

6. Ubah permission-nya :

$ sudo chmod +x /etc/init.d/php-fastcgi

7. Launch php :

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

8. Launch pada StartUp

$ sudo update-rc.d php-fastcgi defaults

9. Pada config :

$ sudo gedit /etc/nginx/sites-available/default

Tambahkan line d’bawah ini :

location ~ \.php$ {
    fastcgi_pass    127.0.0.1:9000;
    fastcgi_index   index.php;
    fastcgi_param   SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
    include         fastcgi_params;
}

Sehingga menjadi :

# You may add here your
# server {
#    …
# }
# statements for each of your virtual hosts

server {

listen   8080; ## listen for ipv4
listen   [::]:8080 default ipv6only=on; ## listen for ipv6

server_name  localhost;

access_log  /var/log/nginx/localhost.access.log;

location / {
root   /var/www;
index  index.html index.htm;
}

location /doc {
root   /usr/share;
autoindex on;
allow 127.0.0.1;
deny all;
}

location /images {
root   /usr/share;
autoindex on;
}

location ~ \.php$ {
fastcgi_pass    127.0.0.1:9000;
fastcgi_index   index.php;
fastcgi_param   SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
include         fastcgi_params;
}

#error_page  404  /404.html;

# redirect server error pages to the static page /50x.html
#
#error_page   500 502 503 504  /50x.html;
#location = /50x.html {
#    root   /var/www/nginx-default;
#}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
#proxy_pass   http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
#fastcgi_pass   127.0.0.1:9000;
#fastcgi_index  index.php;
#fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#includefastcgi_params;
#}

# deny access to .htaccess files, if Apache’s document root
# concurs with nginx’s one
#
#location ~ /\.ht {
#deny  all;
#}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#listen   8000;
#listen   somename:8080;
#server_name  somename  alias  another.alias;

#location / {
#root   html;
#index  index.html index.htm;
#}
#}

# HTTPS server
#
#server {
#listen   443;

#ssl_certificate_key  cert.key;

#ssl_session_timeout  5m;

#ssl_protocols  SSLv3 TLSv1;
#ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv3:+EXP;
#ssl_prefer_server_ciphers   on;

#location / {
#root   html;
#index  index.html index.htm;
#}
#}

10. Restart Nginx :

$ sudo /etc/init.d/nginx restart

*start nginx :

$ sudo /etc/init.d/nginx restart

*stop nginx :

$ sudo /etc/init.d/nginx restart

11. Untuk menjalankan nginx bisa menggunakan :

http://127.0.0.1:8080/ (8080 tergantung port brp yg kita buat pada configurai d’atas)

12. Untuk mencoba apakan ngix kita ah berjalan, buat suatu file *.php pada /var/www/nginx-default/..

*Jika ingin mengubah default upload file /var/www/nginx-default/ menjadi /var/www/ edit pada konfigurasi :

SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;

menjadi :

SCRIPT_FILENAME /var/www/php$fastcgi_script_name;

Contoh buat sebuah file *.php bernama test.php dan isi dengan <? phpinfo (); ?>..

Nanti akan muncul :
