nginx + tomcat load balancing configuration

First, download nginx

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

Second, configure tomcat

   2.1 tomcat01 修改三个端口，http端口为 8088，主页修改内容为：111111
   2.2 tomcat02 修改三个端口，http端口为 8089，主页修改内容为：22222

Third, configure nginx

        server 127.0.0.1:8089 weight=1; 
     }

It is added, upstream to configure the greater the probability tomcat cluster weight is the weight heavy weight greater access to the right weight right, myservers to name their own name. in

        location / {
            proxy_pass http://myservers;
            proxy_redirect default;
        }

中需要引用。注意 http://后面的名字需要与  upstream myServe 的一致。

        server {
        listen       80;
        server_name  127.0.0.1;

listen listening port, server_name is the domain name or IP.

Fourth, start

cmd 命令行启动

    E:\nginx-1.16.1>nginx.exe

V. Close

 cmd 命令行关闭

    E:\nginx-1.16.1>taskkill /im nginx.exe /f

tasklist view the process list of the current system, and then use the taskkill command to kill a process for you

According to the service name

taskkill /im nginx.exe /f

　　/ im immediately
　　/ f terminates the process

According pid

taskkill /pid {pid}

Note that even if closed cmd command line window, nginx can not turn off, you must kill the process. (Command can only kill, kill nor manually)
