准备：一台装有docker的虚拟机或者服务器

1. 拉取mysql镜像：

docker pull mysql:5.6

2. 启动两个mysql容器

master

docker run -p 1006:3306 --name mysql_master -v F:/mysql/mysql_master/conf:/etc/mysql -v F:/mysql/mysql_master/logs:/logs -v F:/mysql/mysql_master/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -itd mysql:5.6

slave

docker run -p 1007:3306 --name mysql_salve -v F:/mysql/mysql_salve/conf:/etc/mysql -v F:/mysql/mysql_salve/logs:/logs -v F:/mysql/mysql_salve/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -itd mysql:5.6

3. 查看容器启动情况

docker ps

4. 使用Navicat工具创建两个连接，分别为master和slave
   

5. 开启binlog日志

主库 修改 F:/mysql/mysql_master/conf/my.cnf

对应容器内路径是/etc/mysql/my.cnf

[mysqld]
server_id=1
log_bin=mysql-bin
binlog_format=ROW

从库

[mysqld]
server-id = 2
relay_log = /var/lib/mysql/mysql-relay-bin
relay_log-index = /var/lib/mysql/mysql-relay-bin.index
log_slave_updates = 1
read_only = 1 

6. 配置好后重启docker容器

docker resatrt 容器名或者容器id

7. 查看binlog状态

show global variables like '%log_bin%';

log_bin为ON是开启状态

8. 在master数据库（主库）中创建同步用户授予用户slave REPLICATION SLAVE权限和REPLICATION CLIENT权限，用于在主从库之间同步数据。

1. 创建用户

CREATE USER 'slave'@'192.168.11.%' IDENTIFIED BY 'slave'

2. 授予用户slave同步权限

GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'slave'@'%';

3. 刷新权限

flush privileges;

9. 查询主库File和Position

    show master status;
   

10. slave库链接master

change master to master_host='192.168.11.1', master_user='slave', master_password='slave', master_port=1006, master_log_file='mysql-bin.000004', master_log_pos= 1271;

11. 启动从库

    start slave;

12.查看从库状态

show slave status;

当Slave_IO_Running和Slave_SQL_Running为Yes时，表示主从配置成功。
