I. environment construction

We have set up 3 WindowsServer2012 servers locally with VMware Workstation, and 2 servers are installed with SqlServer2017 development version database. 1 server installs Nginx and configures reverse agent.

Server information

II download And install Windows version Nginx.

1,download Select the major version.

2. Deliver it to the server and extract it to the appropriate location. Here is the virtual machine, which is solved on disk C. Then open it under nginx\conf file Nginx.conf Documents.

2.1 add forwarding website. For general configuration of Nginx, please refer to blog Nginx +iis reverse proxy . For detailed parameter configuration of Nginx, please refer to the blog Five weight allocation methods of Nginx upstream.

 upstream www.aaa.com  { 
        server  192.168.137.129:808 weight=1; #First test site
        server  192.168.137.128:808 weight=1;  #Second test site
    } 

2.2 configure the reverse proxy pointing address (here www.aaa.com Can be modified at will)

proxy_pass  http://www.aaa.com;

2.3. If port 80 is occupied, modify

listen       80;#This is the original port 80. If the port 80 has been occupied and needs to be modified, you can specify any unused port

2.4. The overall configuration is as follows:

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

    worker_connections  1024;

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

3. Double click to start Nginx.exe The file is located in the nginx root directory. Start the task manager to query whether nginx is running.

4. If node1 server and node2 server deploy WTM application normally. Then visit http://localhost:80 (or custom port number), which can be accessed by polling

 server  192.168.137.129:808 
 server  192.168.137.128:808 .

Modify the challenge strategy, refer to the blog Five weight allocation methods of Nginx upstream.

Visit 192.168.137.130 in the host input browser, and you can access the node1 web service and node2 web service through the node3 reverse proxy server. Achieve load balancing.
