使用docker-compose搭建，直接上配置文件

docker-compose.yml

version: '2'

services:
    mysqlmaster:
      image: docker.io/mysql
      ports:
        - 3306:3306
      environment:
        MYSQL_ROOT_PASSWORD: root
      volumes:
        - "/data/master//mysql:/var/lib/mysql"
        - "/data/master/config/my.cnf:/etc/mysql/my.cnf"
      networks:
        - backend

    mysqlslave:
      image: docker.io/mysql
      ports:
        - 3307:3306
      environment:
        MYSQL_ROOT_PASSWORD: root
      volumes:
        - "/data/slave/mysql:/var/lib/mysql"
        - "/data/slave/config/my.cnf:/etc/mysql/my.cnf"
      networks:
        - backend
networks:
  backend:
    driver: bridge
    ipam:
      driver: default
      config:
      - subnet: 172.18.0.0/24
        gateway: 172.18.0.1

• 进入容器 docker exec -it work_mysqlmaster_1 bash
• mysql -u root -p
• Master: show master status; 得到类似 binlog.000003
• 查看Master的IP docker inspect work_mysqlmaster_1
• Slave: CHANGE MASTER TO MASTER_HOST='172.18.0.2',MASTER_PORT=3306,MASTER_USER='root',MASTER_PASSWORD='root',MASTER_LOG_FILE='binlog.000006',MASTER_LOG_POS=155,get_master_public_key=1;
• Slave: show slave status\G
• Slave: start slave; stop slave;
• Slave: set global server_id=2; 如果提示ids错误，用这个分别对两个mysql设置serverid

my.cnf

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
symbolic-links=0
server-id=1

# Custom config should go here
