用如下命令在ubuntu上安装了mysql之后
sudo apt-get install mysql-server
sudo apt-get install mysql-client
sudo /etc/init.d/mysql start 如果
rpm安装完毕后,直接用
/usr/bin/mysqladmin -u root password “newpasswd”修改密码后出现
错误信息。
解释:YES,说明密码没有问题。可能是限制不让在本地登陆。于是实用
添加 -h 61.139.xx.252绕过本地测试,也未成功
[root@fms1 ok]# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user
[email=%27root%27@%27localhost%27]'root'@'localhost'[/email]
(using password: YES)
[root@fms1 ok]# mysql -h 61.139.xx.252 -u root -p
Enter password:
ERROR 1130 (00000): Host '61.139.76.252' is not allowed to connect to this MySQL server
注释: 1130报错信息说明不允许远程访问。没有给该用户授权
然后重新修改密码后可以正常访问:
[root@fms1 ok]# [color="#ff0000"]/etc/init.d/mysql stop
