master/slave主从数据库手动同步之master-data

 

 master-data参数在建立slave数据库的时候会经常用到,因为这是一个比较好用的参数,默认值为1,默认情况下,会包含change master to,这个语句包含file和position的记录始位置。master-data=2的时候,在mysqldump出来的文件包含CHANGE MASTER TO这个语句,处于被注释状态

 

dump出文件

[root@aeolus1 c_learn]# mysqldump -uroot test --single-transaction --master-data=2 >master-data.sql过滤出change master to信息[root@aeolus1 c_learn]# grep -i "change master to" master-data.sql -- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000012', MASTER_LOG_POS=107;
Copy after login

然后修改

change master to  master_host='xx.xx.xx.xx',master_user='repl',master_password='repl',master_port=3306,master_log_file='mysql-bin.000012',master_log_pos=107;
Copy after login

然后slave从库执行

mysql> change master to  master_host='xx.xx.xx.xx',master_user='repl',master_password='repl',master_port=3306,master_log_file='mysql-bin.000012',master_log_pos=107;
Copy after login

然后

mysql>start slave 
Copy after login

再次执行

mysql>show slave status;
Copy after login

需要注意的是:如果之前配置过服务器链接和密码,从服务器不用reset slave,直接

CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000012', MASTER_LOG_POS=107;
Copy after login
 即可。
