My PHP programming companions with nginx and hhvm for the best configuration. sometime we need some many location or doc root or maybe some many virtual server.

nginx consists of modules which are controlled by directives specified in the configuration file. Directives are divided into simple directives and block directives. A simple directive consists of the name and parameters separated by spaces and ends with a semicolon (;). A block directive has the same structure as a simple directive, but instead of the semicolon it ends with a set of additional instructions surrounded by braces ({ and }). If a block directive can have other directives inside braces, it is called a context (examples: events, http, server, and location).

Directives placed in the configuration file outside of any contexts are considered to be in the main context. The events and http directives reside in the main context, server in http, and location in server.

The rest of a line after the # sign is considered a comment.

This is my configuration with debian using nginx and hhvm and yii2 which no www redirect :

in your /etc/sites-available/default :

	listen   80; ## listen for ipv4; this line is default and implied
        server_name www.sintret.com;

}
server {
  	listen   80; ## listen for ipv4; this line is default and implied
        server_name sintret.com;
