数据库'表名' is marked as crashed and should be repaired

解决方法：

进入/usr/bin下，执行命令

zx@zx-Lenovo-Product:/usr/bin$ ./myisamchk -c -r /var/lib/mysql/Microblog/PL2F_1_ftb_mb026.MYI(数据库表名的完整路径)

可能会提示如下错误：

解决方法：（注意简单使用chmod来改变表的权限是不起作用的）

运行如下命令：

zx@zx-Lenovo-Product:/usr/bin$ sudo ./myisamchk -c -r /var/lib/mysql/Microblog/PL2F_1_ftb_mb026.MYI(数据库表名的完整路径)
