一、实验步骤

1、自行下载pes的tar包

然后解压到家目录下

tar -xzvf pes.tar.gz

2、创建一个目录

mkdir docker-compose-pes-lb2

3、在这个目录下写两个文件docker-compose.yml和haproxy.cfg

docker-compose.yml

version: '3'

services:

  db:

    image: mysql:5.7.44

    container_name: db

    volumes:

      - /root/pes/mysql/data/:/var/lib/mysql/

    expose:

      - 3306

  java0:

    image: tomcat:latest

    container_name: java0

    volumes:

      - /root/pes/java/src/:/usr/local/tomcat/

    expose:

      - 8080

    command: java -jar Project_ExamSystem-V1.0.0.war

  web0:

    image: nginx:latest

    container_name: web0

    volumes:

      - /root/pes/web/dist/:/usr/share/nginx/html/

    expose:

      - 80

  haproxy:

    image: haproxy:latest

    container_name: haproxy

    volumes:

      - ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg

    expose:

      - 5000

      - 5001

      - 8404

    ports:

      - '80:5000'

      - '32100:5001'

      - '33333:8404'

haproxy.cfg
