3. nginx配置

3.1 配置代码

#user  nobody;
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

 #1 start
	upstream linuxidc {
			server localhost:7071;
			server localhost:7072;
			server localhost:7073;
	}
   server {
       listen      7070;
       server_name  localhost;
       location / {
          # root    C:/ngtest2;
         # index  index.html index.htm;
         proxy_pass http://linuxidc;
        }
    }
# 1 end
 #2 start
   server {
       listen      7071;
       server_name  localhost;
       location / {
           root    C:/ngtest1;

        }
    }

# 2 end
 #3 start
    server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        
        #location / {

            #index  index.html index.htm;
            #proxy_pass https://www.baidu.com/;
       # }

        location /baidu {

        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        # 3 end
    }
}

3.2 代码说明及效果图

3.2.1 不同端口代理不同应用

#2 start
   server {
       listen      7071;
       server_name  localhost;
       location / {
           root    C:/ngtest1;
         # index  index.html index.htm;
         #proxy_pass https://tms;
         #proxy_pass https://www.baidu.com/;
        }
    }
   server {
       listen      7072;
       server_name  localhost;
       location / {
           root    C:/ngtest2;
         # index  index.html index.htm;
         #proxy_pass https://tms;
        }
    }
   server {
       listen      7073;
       server_name  localhost;
       location / {
          root    C:/ngtest3;
         # index  index.html index.htm;
         #proxy_pass https://tms;
        }
    }

# 2 end

3.2.3 同一端口号代理不同应用

 #3 start
    server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        
        #location / {
          #  root   C:\ngtest;
            #index  index.html index.htm;
            #proxy_pass https://www.baidu.com/;
       # }

        location /baidu {
            #root   html;
            #index  index.html index.htm;
            proxy_pass https://www.baidu.com/;

        location = /50x.html {
            root   html;
        }
        # 3 end

3.2.5 负载均衡

默认采用的轮询方式

#1 start
	upstream linuxidc {
			server localhost:7071;
			server localhost:7072;
			server localhost:7073;
	}
   server {
       listen      7070;
       server_name  localhost;
       location / {
          # root    C:/ngtest2;
         # index  index.html index.htm;
         proxy_pass http://linuxidc;
        }
    }
# 1 end
