Linux下mysql ERROR 1045: Access denied for user: (Using password: NO)

每次启用mysql都出现这个问题 然后我键入命令# mysql -pEnter password: Welcome to the MySQL monitor.  Commands endwith ; or \g.Your MySQL connection id is 35 to server version: 4.0.20-standard Type 'help;' or '\h' for help. Type'\c' to clear the buffer.

mysql> 这样才能用，不过想给mysql备份就不可以了，

键入#mysqldump database>databak.sql就又出现RROR 1045: Access denied for user: (Using password: NO)怎么才能接着键入mysql就能使用，而且能对

mysql进行备份 

 解决办法：登陆mysql,然后执行下面语句:set password for =password('');flush privileges;然后再重新登陆,就达

到你的要求了
