问题描述
我有2个具有主/从配置的MySql,复制失败. MySql Master崩溃了,并在 mysql-bin.index 中创建了一个新寄存器.我删除了此新寄存器,因为该文件在文件系统中不存在.然后,MySql Master成功重新启动.
I have 2 MySql with a master/slave configuration and the replication is failing. The MySql Master crashed and a new register in the mysql-bin.index was created. I deleted this new register because this file was not existed in the file system. Then the MySql Master restarted successfully.
现在,我在奴隶中遇到了下一个错误:
Now, I have the next error in the slave:
mysql> show slave status \G

如果我执行显示主状态"以查看mysql bin日志文件和位置:
If I execute the "show master status" for view the mysql bin log file and the position:
mysql> show master status \G
*************************** 1. row ***************************
File: mysql-bin.001050
Position: 55586895
Binlog_Do_DB: aaa
Binlog_Ignore_DB: xxx,yyy,zzz,mysql
然后我将新配置设置为从属:
Then I set new config to the slave:
STOP SLAVE;
CHANGE MASTER TO
MASTER_HOST='10.64.253.99',
MASTER_USER='slaveUser',
MASTER_PASSWORD='12345',
MASTER_LOG_FILE='mysql-bin.001050',
MASTER_LOG_POS=55586895;
START SLAVE;
如果我再次检查从站状态,我将遇到相同的错误:
And if I check slave status again I have the same error:
mysql> show slave status \G

我已经在MySql Master中检查到mysql-bin.001050存在并且不为空.
I have checked in the MySql Master that the mysql-bin.001050 exist and is not empty.
这是一个生产环境,然后每分钟插入新数据.位置值可以以分钟或秒为单位更改.我不知道这是否有问题.
This is a production environment then new data are inserted every minute. The position value can to change in minutes or seconds. I don't know if this is a problem.
max_allowed_packet变量在两个MySql(16M)中具有相同的值.
The max_allowed_packet variable has the same value in the two MySql (16M).
为什么从站找不到二进制日志文件?
Why can not the slave find the binary log file?
推荐答案
您可以尝试以下操作:
- 从站:
stop slave;
- Master:
flush logs
-
主:
show master status; — take note of the master log file and master log position
- Slave:
stop slave;
- Master:
flush logs
Master:
show master status; — take note of the master log file and master log position
从站:CHANGE MASTER TO MASTER_LOG_FILE='log-bin.00000X', MASTER_LOG_POS=106;
