Windows installs Nginx and configures load balancing

Introduction to Nginx

Nginx is a free, open source, high-performanceHTTP serverandreverse proxy server; It is also an IMAP, POP3, SMTP proxy server; Nginx can be used as an HTTP server to publish the website, and Nginx can be used as a reverse proxy to implement load balancing.

• Nginx uses an event-driven architecture that enables it to support millions of TCP connections
• A high degree of modularization and free software licenses make third-party modules emerge in an endless stream (open source)
• Nginx is a cross-platform server that can run on Linux, Windows, FreeBSD, Solaris, AIX, Mac OS and other operating systems
• Very high stability

1. Install Nginx to realize double-click startup and double-click shutdown

1. Download Nginx

Official download address: http://nginx.org/en/download.html

Choose any windows version

2. After getting the installation package, just put it in a directory you like, and enter the directory

3. Double-click to start, double-click to close

3.1. Double-click to start, and click the nginx.exe file.

3.2. Double click to close

3.2.1. Create a 关闭nginx.txtfile named and writetaskkill /f /t /im nginx.exe

3.2.2. Change the suffix of the file to 关闭nginx.bata file

3.3. Create a shortcut and put it on the desktop

4. Test

4.1. Double-click the nginx.exe file

4.2. The address accessed by the browser localhost, as shown below, proves that nginx started successfully

4.3. Close nginx, double-click 关闭nginx.batthe file, and refresh localhostthe page. The following display proves that nginx is closed successfully

2. Configure load balancing and test

1. Open confthe directory undernginx.conf

2. Modify nginx.confthe file

In fact, I just added the code of upstream server_listand proxy_pass, and the others are all included in this configuration file. The following is all the code of my entire nginx.conffile

worker_processes  1;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;
	
	# 负载均衡配置访问路径 serverList名字随便取
	upstream serverList{
	   # 这个是tomcat的访问路径
	   server localhost:8080;
	   server localhost:9090;
	}

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
			proxy_pass http://serverList;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }



}

3. Use the jmeter tool to test

For students who don’t know how to use it jmeter, you can read this article of mine: jmeter installation and use, full picture and text explanation_I Can’t Recognize Your Blog-CSDN Blog

Students who will not start two identical projects with different ports at the same time can read this article of mine: idea to start two projects with the same service but different ports at the same time, full diagram_I Can’t Recognize Your Blog-CSDN Blog

3.1. Double-click to start the nginx.exe file

3.2. Start two springboot projects: idea implements two projects with the same service but different ports at the same time

3.3, configure jmeter: jmeter installation and use, full picture and text explanation

3.5. Check the springboot console output information

3.5.1, port 8080

We can see that nginxby default, polling is used to achieve load balancing, and we can see that there are ten pieces of data under port 8080

3.5.2, 9090 port

There are also ten pieces of data under the port 9090
