MYSQL8 裸机搭主从

步骤很我简单

在主机上运行以下SQL

SET SQL_LOG_BIN=0;   ##关闭binlog
grant all privileges on *.* to root@'localhost' with grant option;
create user 'repl'@'192.168.68.89' identified WITH mysql_native_password by '123456' PASSWORD EXPIRE NEVER ; 
grant replication slave on *.* to 'repl'@'192.168.68.89' with grant option; 
SET SQL_LOG_BIN=1;   ##打开binlog

在从机上运行以下SQL

change master to master_host='192.168.68.89',master_port=3388,master_user='repl',master_password='123456',master_auto_position=1; 
start slave; 
show slave status\G

在主机验证

mysql> show slave hosts;
+-----------+------------+------+-----------+--------------------------------------+
| Server_id | Host       | Port | Master_id | Slave_UUID                           |

+-----------+------------+------+-----------+--------------------------------------+
1 row in set (0.00 sec)

mysql> show processlist;

3 rows in set (0.00 sec)

在从机验证
