2、master 重启并查看master 状态

show master status;

3、master 开启远程访问权限

grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
FLUSH PRIVILEGES

4、master 关闭防火墙

systemctl stop firewalld.service

二、slave 服务器配置

1、slave 服务器my.cnf 配置

server_id=2
log-bin=mysql-bin
binlog_do_db=test

2、slave 服务器重启并配置指向master

change master to master_host='192.168.1.7',master_user='root',master_password='123456', master_log_file='mysql-bin.000001',master_log_pos=154;

3、slave 开启同步

start slave

4、查看slave 状态

show slave status G;

结果：
Slave_IO_State: Waiting for master to send event
