Migrate From Apache to Nginx (Engin X) on Ubuntu VPS

I have low end of VPS, there are has minim of spesification hardware, googling and found recommended using Nginx for web server to reduce using of memory.

1. Stop service for Apache

sudo service apache2 stop

2. Installing Nginx PHP5-FPM

sudo apt-get install nginx php5-fpm

3. Configure PHP5-FPM

need to configuring PHP5 handler by Nginx

sudo nano /etc/php5/fpm/php.ini

find (CTRL + W) cgi.fix_pathinfo word and set like the below value:

cgi.fix_pathinfo=0

will modify another PHP configuration

sudo nano /etc/php5/fpm/pool.d/www.conf

find the "listen = ", We will modify this to use a socket for communication with the web server

listen = /var/run/php5-fpm.sock

Restart the PHP-FPM

sudo service php5-fpm restart

5. Set the Vhost of Nginx

sudo nano /etc/nginx/sites-available/myvhost.conf

add this lines to configure your site, for more example script you can find at /etc/nginx/sites-available/default

server {
    listen 80;

    root /var/www;
    index index.php index.html index.htm;
}

unlink the default configuration

sudo unlink /etc/nginx/sites-enabled/default 

Start the Nginx web server

sudo nano service nginx start

6. Remove Apache

to find all dependcies of Apache you filter like this:

dpkg --get-selections | grep apache

will display:

apache2      install
apache2-doc     install
apache2-mpm-prefork    install
apache2-threaded-dev    install
apache2-utils     install
apache2.2-bin     install
apache2.2-common    install
libapache2-mod-auth-mysql   install
libapache2-mod-passenger   install

remove

sudo apt-get remove apache2 apache2-mpm-prefork apache2-utils apache2.2-bin apache2.2-common libapache2-mod-auth-mysql libapache2-mod-php5

for the clear remove dependencies run this command

sudo apt-get autoremove
