第二步，修改从服务器的server-id
[root@serv08 ~]# cat /etc/my.cnf | grep server-id
server-id = 1
#server-id = 2
[root@serv08 ~]# vim /etc/my.cnf
[root@serv08 ~]# cat /etc/my.cnf | grep server-id
server-id = 2
#server-id = 2
[root@serv08 ~]# /etc/init.d/mysqld restart
Shutting down MySQL... SUCCESS!
Starting MySQL.. SUCCESS! #可以查看从服务器中的数据文件
[root@serv08 ~]# cd /usr/local/mysql/data/
[root@serv08 data]# ll

第三步，从服务器清空日志
mysql> show binary logs;
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 1
Current database: *** NONE ***+------------------+-----------+
| Log_name | File_size |

| mysql-bin.000002 | 1035309 |
| mysql-bin.000003 | 126 |
| mysql-bin.000004 | 126 |
| mysql-bin.000005 | 107 |
+------------------+-----------+
5 rows in set (0.00 sec)mysql> reset master;
Query OK, 0 rows affected (0.02 sec)mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 107 |
+------------------+-----------+
1 row in set (0.00 sec)mysql> show slave status;
Empty set (0.00 sec)
第四步，从服务器通过change master to命令修改设置
mysql> change master to
-> master_host='192.168.1.11',
-> master_user='larry',
-> master_password='larry',
-> master_port=3306,
-> master_log_file='mysql-bin.000001',
-> master_log_pos=107;
Query OK, 0 rows affected (0.01 sec)
第五步，开启slave。
mysql> show slave status \G;
