MySQL ERROR 1033 (HY000): Incorrect information in file. 处理一例

昨天遇到问题，几个表都一样的情况：

mysql> desc domains;
ERROR 1033 (HY000): Incorrect information in file: './xxx/xxx.frm'
mysql>

然后看一下状态：

mysql> show engines;
+------------+----------+----------------------------------------------------------------+
| Engine     | Support  | Comment                                                        |
+------------+----------+----------------------------------------------------------------+
| MyISAM     | DEFAULT  | Default engine as of MySQL 3.23 with great performance         |
| MEMORY     | YES      | Hash based, stored in memory, useful for temporary tables      |
| InnoDB     | DISABLED | Supports transactions, row-level locking, and foreign keys     |

再看一下log信息，发现有错误提示：

140518 11:11:11  mysqld started
InnoDB: Unable to lock ./ib_logfile1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
InnoDB: Error in opening ./ib_logfile1

于是网上找一下。解决很简单：

stop mysql

mv ib_logfile1 ib_logfile1.bak

cp -a ib_logfile1.bak ib_logfile1

start mysql

检查，一切正常。
