Nginx Virtual machine host uses different root paths depending on the domain name

A description of the application scenario

To develop the needs of colleagues, nginx in the development environment can use different root paths depending on the domain name.

For example, if the domain name is game4.xxx.com, use the root path as/data/public/game4

Game5.xxx.com, use the root path as/data/public/game5

game6.xxx.com, the root path is/data/public/game6

Two-way solution

server{        listen      80;         server_name *.xxx.com;         set  $game _name game4;        if  ($host  ~  "Game5")         {            set  $game _name game5;        }         if  ($host  ~  "Game6")          {           set  $game _name  game6;        }         root        /data/public/$game _name/;          client_max_body_size 5m;        autoindex off;         location / {             if  (!-e  $request _filename) {                rewrite /(. *)  /index.php last;                                        }             index index.php;             autoindex off;        }         location ~ \.php$ {             fastcgi_pass   127.0.0.1:9000;             fastcgi_index  index.php;             fastcgi_param  SCRIPT_FILENAME   $document _root/$fastcgi _script_ name;            include         fastcgi_params;        }}

This sets the variable $game_name, and then uses the variable in the root path

Introduction of three related NGINX instructions

1.set instruction

Used to define a variable and assign a value to the variable

Scope of If,location,server

such as the above

Set $game _name game4;

2.if instruction

if (condition) {...}

The scope of action is

Such as:

if ($host ~ "game-taiwan-5")

{

Set $game _name game5;

}

The IF directive is used to check if a condition conforms, and if the condition is met, the contents inside the curly braces are executed.
