mysql数据库只能建不能删的错误提示及处理方法：
mysql> drop database zabbixaa; ERROR 145 (HY000): Table ‘./mysql/proc‘ is marked as crashed and should be repaired
处理方法：直接在mysql数据库里面使用root帐号登录后，进行修复：
mysql> repair table mysql.proc; +------------+--------+----------+----------+ | Table | Op | Msg_type | Msg_text | +------------+--------+----------+----------+ | mysql.proc | repair | status | OK | +------------+--------+----------+----------+ 1 row in set (0.05 sec)
再次执行删除正常
mysql> drop database zabbixaa; Query OK, 0 rows affected (0.02 sec)
