遇到的问题：
mysqldump: Error 1194: Table 'user' is marked as crashed and should be repaired when dumping table `user` at row: 1161435

登陆到数据库：
mysql> select count(*) from user;
+----------+
| count(*) |
+----------+
|  1840589 |
+----------+
1 row in set (0.00 sec)
mysql> repair table user;
+--------------+--------+----------+------------------------------------------------+
| Table       | Op    | Msg_type | Msg_text                                     |
+--------------+--------+----------+------------------------------------------------+
| txtotal.user | repair | warning  | Number of rows changed from 1840589 to 1161435 |
| txtotal.user | repair | status | OK                                           |

2 rows in set (50.04 sec)
mysql> select count(*) from user;
+----------+
| count(*) |
+----------+
|  1161435 |
+----------+
1 row in set (0.20 sec)
mysql> check table  user;
+--------------+-------+----------+----------+
| Table       | Op | Msg_type | Msg_text |
+--------------+-------+----------+----------+
| txtotal.user | check | status | OK    |
+--------------+-------+----------+----------+
1 row in set (15.05 sec)

数据表已经修复完成，只是记录从原来的1840589 条减少到了1161435 条，不是太清楚还有没有更好的方法去实现修复。
