ngin xvirtual host | nginx server block

we’ll show you, how to create Nginx Virtual Host, aka Nginx Server Block. In one of our previous tutorials we explained How to install and configure LNMP (Nginx, MySQL and PHP) server on a Debian 6 (squeeze) VPS, now we’re going to look at how to set up a new server block (virtual host) for each new domain.

Note: “VirtualHost” is an Apache term. Nginx does not have Virtual hosts, it has “Server Blocks” that use the server_name and listen directives to bind to tcp sockets.

The following script can be used to set up a new server block on your Nginx server.

#!/usr/bin/env bash
#
# Nginx - new server block
# http://rosehosting.com

# Functions
ok() { echo -e '\e[32m'$1'\e[m'; } # Green
die() { echo -e '\e[1;31m'$1'\e[m'; exit 1; }

# Variables
NGINX_AVAILABLE_VHOSTS='/etc/nginx/sites-available'
NGINX_ENABLED_VHOSTS='/etc/nginx/sites-enabled'
WEB_DIR='/var/www'
WEB_USER='www-data'

# Sanity check
[ $(id -g) != "0" ] && die "Script must be run as root."
[ $# != "1" ] && die "Usage: $(basename $0) domainName"

# Create nginx config file
cat > $NGINX_AVAILABLE_VHOSTS/$1 <<EOF
server {
  server_name $1;
  listen 80;
  root $WEB_DIR/$1/public_html;
  access_log $WEB_DIR/$1/logs/access.log;
  error_log $WEB_DIR/$1/logs/error.log;
  index index.html index.php;
  location / {
    try_files \$uri \$uri/ @rewrites;
  }
  location @rewrites {
    rewrite ^ /index.php last;
  }
  location ~* \.(jpg|jpeg|gif|css|png|js|ico|html)$ {
    access_log off;
    expires max;
  }
  location ~ /\.ht {
    deny  all;
  }
  location ~ \.php {
    fastcgi_index index.php;
    fastcgi_split_path_info ^(.+\.php)(.*)$;
    include /etc/nginx/fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_param SCRIPT_FILENAME \$document_root\$fastcgi_script_name;
  }
}
EOF

# Creating {public,log} directories
mkdir -p $WEB_DIR/$1/{public_html,logs}

# Creating index.html file
cat > $WEB_DIR/$1/public_html/index.html <<EOF
<!DOCTYPE html>
<html lang="en">
<head>
        <title>$1</title>
        <meta charset="utf-8" />
</head>
<body class="container">
        <header><h1>$1<h1></header>
        <div id="wrapper"><p>Hello World</p></div>
        <footer>© $(date +%Y)</footer>
</body>
</html>
EOF

# Changing permissions
chown -R $WEB_USER:$WEB_USER $WEB_DIR/$1

# Enable site by creating symbolic link
ln -s $NGINX_AVAILABLE_VHOSTS/$1 $NGINX_ENABLED_VHOSTS/$1

# Restart
echo "Do you wish to restart nginx?"
select yn in "Yes" "No"; do
    case $yn in
        Yes ) /etc/init.d/nginx restart ; break;;
        No ) exit;;
    esac
done

ok "Site Created for $1"

Here’s what it does, in a nutshell:

  1. Creates a new directory for the site (/var/www/DOMAIN.COM/public_html)
  2. Creates a new directory for log files (/var/www/DOMAIN.COM/logs)
  3. Sets correct owner/group.
  4. Creates a simple index.html file to show the site is working.
  5. Asks for restart.

To use the script type:

./nginx_vhost.sh  newdomain.com

The script should work on Debian, Ubuntu and closely related distributions.

If you use one of our Ubuntu VPS Hosting plans, you don’t have to create Nginx Virtual Host yourself, you can simply ask our expert Linux admins to create Nginx server block for you. They are available 24×7 and will take care of your request immediately.
