MySQL:"怎样重新设置一个忘记的口令",这_MySQL
如果你忘记了MySQL的root用户的口令,你可以用下列过程恢复它。
kill `cat /mysql-data-directory/hostname.pid`
使用--skip-grant-tables选项重启mysqld。
用mysql -h hostname mysql连接mysqld服务器并且用一条GRANT命令改变口令。也可以用mysqladmin -h hostname -u user password 'new password' 进行。
这是从baidu,google上能搜索到的,其实也是MySQL手册中(8.9 怎样重新设置一个忘记的口令),所提到了,但我这次在windows 下却失败了...
如果你忘记了MySQL的root用户的口令,你可以用下列过程恢复它。
通过发送一个kill(不是kill -9)到mysqld服务器来关闭mysqld服务器。pid 被保存在一个.pid文件中,通常在MySQL数据库目录中:
kill `cat /mysql-data-directory/hostname.pid`
你必须是一个UNIX root用户或运行服务器的相同用户做这个。
使用--skip-grant-tables选项重启mysqld。
用mysql -h hostname mysql连接mysqld服务器并且用一条GRANT命令改变口令。见7.26 GRANT和REVOKE句法。你也可以用mysqladmin -h hostname -u user password 'new password' 进行。
用mysqladmin -h hostname flush-privileges或用SQL命令FLUSH PRIVILEGES来装载权限表
这是从baidu,google上能搜索到的,其实也是MySQL手册中(8.9 怎样重新设置一个忘记的口令),所提到了,但我这次在windows 下却失败了...
因为我只有一个用户:select user,host from user时
| root | localhost |
后来我用update user set password=PASSWORD(''); 可是我用错了,我用成了:update user set password='';
突然退出后,再登录就无法登录了,真是没法啊.
按以上的步骤进行到mysqld --skip-grant-tables后无报错,但mysql还是没有启动,所以无法用后面的mysql登录,因为此时3306都没有打开.
无可赖何之下只得重装它(教训!).
