Nginx Processing Web Request analysis

First, the domain-based virtual server

Nginx first determines which server domain to use to process the request, and the following example has 3 virtual servers listening on the *:80 port.

server { listen 80; server_name nginx.org www.nginx.org; ... } server { listen 80; server_name nginx.net www.nginx.net; ... } server { listen 80; server_name nginx.com www.nginx.com; ...

}

在上面的配置中，nignx会根据HTTP请求“Host”的值，确定具体哪一个server接收web请求。如果“Host”不存在或者Host的值无法匹配任何sever中的$server_name，nginx就会把web请求送到默认的server中。如果没有定义default_server，默认将请求传递给第一个server。

默认server的配置方法如下：


server {      listen       80  default_server;      server_name  nginx.net  www.nginx.net;      ...

}

Second, the processing of IP and domain-based virtual host server {      listen       192.168.1.1:80;      server_name  nginx.org  www.nginx.org;      ... } server {      listen       192.168.1.1:80;      server_name  nginx.net  www.nginx.net;      ... } server {      listen       192.168.1.2:80;      server_name  nginx.com  www.nginx.com;      ... }

上面的配置中，nginx首先匹配IP地址和端口，然后在确定响应IP下的server_name，如果没有找到任何匹配的server_name，ngixn将请求传递给默认server。例如，当nginx收到来自 192.168.1.1:80 端口的请求www.nginx.com（无法匹配192.168.1.1下的任何一个server_name），The default server is not defined in the previous example, and the request is passed to the first server.

The default server configuration method is as follows:

Note: Nginx can define multiple default servers for different IP addresses and ports

eg

server {      listen        192.168.1.1:80;      server_name   nginx.org  www.nginx.org;      ... } server {      listen        192.168.1.1:80  default_server;      server_name   nginx.net  www.nginx.net;      ... } server {      listen        192.168.1.2:80  default_server;      server_name   nginx.com  www.nginx.com;      ...

}
