Slave node

1 Keep the database consistent with the master

create database testdb character set=utf8;
use testdb;
create table t1(
	id int,
    name varchar(200)
);

2 Stop the database service

net stop mysql

3 Edit the my.ini file and add the following configuration under [mysqld]

#从服务只需要配置一个server-id即可
server-id=2

4 Configure the slave service

-- 在mysql内 先停止 slave服务
stop slave;
-- 配置slave服务信息 注意 master_log_file 和 master_log_pos 和之前查看master的状态要保持一致
change master to 
master_host='127.0.0.1',
master_port=3307,
master_user='slave',
master_password='root',
master_log_file='mysql-bin.000002',
master_log_pos=444;
-- 启动 slave服务
start slave;
-- 查看 slave状态 看是否开启
-- Slave_IO_Running: Yes #负责与主机的io通信
-- Slave_SQL_Running: Yes #负责自己的slave mysql进程
show slave status;

test

Insert data on the main service and the slave service will automatically read the binlog log and back up the data
