刚刚迁移一个项目到新安装的linux系统下,因为要用mysql所以安装了个:

yum install mysql

yum install mysql-server

然后启动mysql服务:

service mysqd start

这时候已经可以登陆了,只是root用户应该没有密码的,未免不安全,故设置密码:

mysqladmin password ‘123’

然后,然后就无法登陆了。。。无论输入密码123还是不输入密码都登陆不了。。。求各位大神解答。

我只能先停止服务,再重置密码了,第二步是用特殊的模式进入mysql,非长久之计:

service mysqld stop
mysqld_safe --skip-grant-tables &

好了,可以进入了:

mysql -uroot -p

选择数据库:

use mysql;

设置密码:
update user set password=PASSWORD("newpass")where user="root";
更新权限:
flush privileges;
退出:

quit

重启mysql服务:
service mysqld restart
新密码进入:
mysql -uroot -p
