Docker中MySQL主从复制

[mysqld]
## 同一局域网内注意要唯一
server-id=100
## 开启二进制日志功能，可以随便取（关键）log-bin=mysql-bin

[mysqld]
## 设置server_id,注意要唯一
server-id=101  
## 开启二进制日志功能，以备Slave作为其它Slave的Master时使用
log-bin=mysql-slave-bin   
## relay_log配置中继日志
relay_log=edu-mysql-relay-bin  

show master status;

docker inspect 容器ID
