MySql更改mysql密码[ERROR]无法找到messagefile

Question

我想更改mysql密码（How to reset or change the MySQL root password?）

日志：

root@vm87297:[/usr/share/mysql]: 
$ sudo /etc/init.d/mysql stop
* Stopping MySQL database server mysqld                                 [ OK ] 

root@vm87297:[/usr/share/mysql]: 
$ sudo mysqld --skip-grant-tables &
[1] 6503

root@vm87297:[/usr/share/mysql]: 
$ 140820  6:11:20 [ERROR] Can't find messagefile '/usr/share/mysqlmyisam-recover-options = BACKUP/errmsg.sys'
^C
[1]+  Exit 1                  sudo mysqld --skip-grant-tables
