mysql表ERROR 144 (HY000)Table 'dede_archives' is marked

1、故障现象

mysql> select count(*) from dede_archives;
ERROR 144 (HY000): Table '.xx' is marked as crashed and last (automatic?) repair failed

2、故障原因

Mysqld进程在数据写入时被意外关闭

意外关闭计算机

硬件故障

3、mysql官方解决方案

官方文档：https://dev.mysql.com/doc/refman/5.6/en/myisam-table-maintenance.html

3.1 check table  检查表的完整性

mysql> check table xx FAST  QUICK; /*快速检查表*/

或者

mysql> check table xx EXTENDED; /*全表检查,耗时长*/

正常输出：

+-----------------------+-------+----------+----------+

| Table                 | Op    | Msg_type | Msg_text |

+-----------------------+-------+----------+----------+

| xx                    | check |
status   | OK       |

+-----------------------+-------+----------+----------+

1 row in set (0.16 sec)

3.2 REPAIR TABLE  修复表 适用于MyISAM

mysql> REPAIR TABLE xx;

正常输出：

+-------------------------+--------+----------+----------+

| Table                   | Op     | Msg_type | Msg_text |

+-------------------------+--------+----------+----------+

| xxxx                    | repair | status   | OK      
|

+-------------------------+--------+----------+----------+

1 row in set (0.24 sec)

3.3 myisamchk 快速修复表（恢复模式，并重建索引文件）

C:\>myisamchk -r xx

输出：

- recovering (with sort) MyISAM-table
'xx'

Data records: 11543

- Fixing index 1

- Fixing index 2

- Fixing index 3

- Fixing index 4

备注：3.2和3.3任选一个进行修复

      在进行检查和修复表之前，需要对表和数据库进行备份

MyISAM表维护也可以使用SQL语句完成，该语句执行与myisamchk可以执行的操作类似的 操作：

• 要检查MyISAM表，请使用 CHECK TABLE。

• 要修复MyISAM表，请使用 REPAIR TABLE。

• 要优化MyISAM表，请使用 OPTIMIZE TABLE。

• 要分析MyISAM表，请使用 ANALYZE TABLE。

3.4 迁移数据库（如果由于底层存储损坏导致的表故障）

    使用mysqldump进行备份恢复

扩展
