1. 创建 mysql-master 配置文件
mkdir -p /root/docker/mysql-master/conf
vim /root/docker/mysql-master/conf/my.cnf

[client]
# 客户端默认字符集
default_character_set=utf8mb4
[mysql]
# 默认字符集
default_character_set=utf8mb4
[mysqld]
# 设置唯一id
server_id=1001
# pid文件

2. 创建 mysql-slave1 配置文件
mkdir -p /root/docker/mysql-slave1/conf
vim /root/docker/mysql-slave1/conf/my.cnf

3. 启动容器 master
   docker run -d -p 13306:3306 \
   --restart always \
   --privileged \
   --name mysql-master \
   -e MYSQL_USER=admin \
   -e MYSQL_PASSWORD=admin123 \
   -e MYSQL_ROOT_PASSWORD=admin123 \
   -v /root/docker/mysql-master/logs:/var/log/mysql \
   -v /root/docker/mysql-master/data:/var/lib/mysql \
   -v /root/docker/mysql-master/conf:/etc/mysql/conf.d \
   mysql:5.7

4. 启动容器 slave1
   docker run -d -p 13307:3306 \
   --restart always \
   --privileged \
   --name mysql-slave1 \
   -e MYSQL_USER=admin \
   -e MYSQL_PASSWORD=admin123 \
   -e MYSQL_ROOT_PASSWORD=admin123 \
   -v /root/docker/mysql-slave1/logs:/var/log/mysql \
   -v /root/docker/mysql-slave1/data:/var/lib/mysql \
   -v /root/docker/mysql-slave1/conf:/etc/mysql/conf.d \
   mysql:5.7

5. 进入 master 容器执行操作
   docker exec -it mysql-master /bin/bash
   mysql -uroot -padmin123
   # 创建同步用户
   CREATE USER 'slave'@'%' IDENTIFIED BY 'slave-sync';
   # 授权同步用户
   GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'slave'@'%';
    # 查看 master 状态, 记录 File 和 Position
show master status;

6. 进入 slave1 容器执行操作
   docker exec -it mysql-slave /bin/bash
   mysql -uroot -padmin123
   # 切换master
   change master to master_host='宿主机ip', master_user='同步用户用户名', master_password='同步用户密码', master_port=master端口, master_log_file='刚刚记录的File', master_log_pos=刚刚记录的position, master_connect_retry=同步重试隔秒;
   # 启动从slave
   start slave;
   # 观察同步状态 Slave_IO_Running 和 Slave_SQL_Running 是否都为yes
   show slave status \G;

mysql> change master to master_host='172.19.6.128', master_user='slave', master_password='slave-sync', master_port=13306, master_log_file='prod-mysql-bin.000003', master_log_pos=617, master_connect_retry=30;
