我有2个具有主/从配置的MySql,并且复制失败 . MySql Master崩溃,并创建了 mysql-bin.index 中的新寄存器 . 我删除了这个新寄存器,因为该文件在文件系统中不存在 . 然后MySql Master重新启动成功 .
现在,我有奴隶的下一个错误:
mysql> show slave status \G

如果我执行“show master status”来查看mysql bin日志文件和位置:
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奴隶:
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;
如果我再次检查奴隶状态,我有同样的错误:
mysql> show slave status \G

我已经在MySql Master中检查了mysql-bin.001050是否存在且不为空 .
这是一个 生产环境 环境,然后每分钟插入新数据 . 位置值可以在几分钟或几秒内改变 . 我不知道这是不是一个问题 .
max_allowed_packet变量在两个MySql(16M)中具有相同的值 .
为什么奴隶找不到二进制日志文件?

你可以试试这个:
奴隶:
stop slave;
大师:
flush logs
大师:
show master status; — take note of the master log file and master log position
奴隶:
CHANGE MASTER TO MASTER_LOG_FILE='log-bin.00000X', MASTER_LOG_POS=106;
奴隶:
start slave
;
