docker images

Create the mounting directory

mkdir -p /data/nginx/{conf,conf.d,html,logs}

##Write nginx, conf configuration file , and put it in the folder

# for more information on configuration, see:

user nginx;

# load dynamic modules. see /usr/share/nginx/readme.dynamic.

        server 182.254.161.54:8089 weight=5;
  }

}

Start the container

Copy the code The code is as follows:

docker run --name mynginx -d -p 82:80 -v /data /nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx

View started containers

docker ps

I have previously deployed two tomcats in docker, one is port 8088, the other is port 8089, and entered the two containers to write simple pages

Access port 8088

Access port 8089

Now access the contents of two tomcats through nginx to achieve the load balancing function. Due to the difference, it can better reflect the load balancing function. The content of the two pages is different, but the access paths are the same, just reverse through nginx The proxy goes to rotate access
