Mysql数据库无法启动,具体如下:
[root@testdb var]#service mysql start
Starting MySQL... ERROR! The server quit without updating PID file (/usr/local/mysql/mysql.pid).
初看,好像是权限问题,但仔细检查权限,没有发现问题,所以进入错误日志看
[root@testdb var]# more testdb.err

查看日志,发现如下:
InnoDB: Ignoring the redo log due to missing MLOG_CHECKPOINT between the checkpoint 3970243421 and the end 3970243072.
事务日志有断档,估计也找不出来了,基于此,只能把原来的事务日志ib_logfile0和ib_logfile1重命名或者删除掉,然后再重新启动
[root@testdb var]#service mysql start
Starting MySQL...SUCCESS!
