NGINX server blocks in Centos 6

How to setup NGINX server blocks (aka VirualHosts) on Centos
Step One — Set Up New Document Root Directories
sudo mkdir -p /var/www/example.com/html
sudo mkdir -p /var/www/test.com/html

sudo chown -R $USER:$USER /var/www/example.com/html

Step Two — Create Sample Pages for Each Site
Step Three — Create Server Block Files for Each Domain
The sites-available directory will keep all of our server block files, while the sites-enabled directory will hold symbolic links to server blocks that we want to publish.

sudo mkdir /etc/nginx/sites-available
sudo mkdir /etc/nginx/sites-enabled

sudo vi /etc/nginx/nginx.conf

Add these lines to the end of the http {} block:

include /etc/nginx/sites-enabled/*.conf;
server_names_hash_bucket_size 64;

Create the First Server Block File

sudo cp /etc/nginx/conf.d/default.conf /etc/nginx/sites-available/example.com.conf

sudo nano /etc/nginx/sites-available/example.com.conf

server {
listen 80
server_name example.com www.example.com;
location / {
root /var/www/example.com/html;
index index.html index.htm;
try_files $uri $uri/ =404;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}


Create the Second Server Block File

sudo cp /etc/nginx/conf.d/default.conf /etc/nginx/sites-available/example2.com.conf

Step Four — Enable the New Server Block Files

sudo ln -s /etc/nginx/sites-available/kabbu.ng.conf /etc/nginx/sites-enabled/kabbu.ng.conf
sudo ln -s /etc/nginx/sites-available/umscholar.org.conf /etc/nginx/sites-enabled/umscholar.org.conf

Restart NGINX
/etc/init.d/nginx restart
