在做维护的时候,有一天有这样的客户给我发了一个网址,说连接不了,然后我检查了一下是他的数据库超容了,要删除一些数据才会正常,但是还有的是一些没有权限也会这样的问题。 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ERROR 1045 (28000): Access denied for user 'sq8xxxxx'@'locahost'(using password:YES) 1:打开开始里MYSQL的MySQL Command Line Client 输入你的密码[就是安装时设的那个]
2:在mysql>后输入:UPDATE mysql.user SET Password = OLD_PASSWORD('密码')
3:在提示符-> 后输入:WHERE Host = 'localhost' AND User = '用户名'; 回车后提示:Query OK, 0 rows affected (0.16 sec) Rows matched: 0 Changed: 0 Warnings: 0 4:在mysql>后输入:FLUSH PRIVILEGES; 回车后提示:Query OK, 0 rows affected (0.19 sec) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 启动mysql服务,登录到mysql数据库, 输入命令为: [root @localhost root]# /usr/bin/mysql -u sq8xxxx -p * (依据lniux版本兼容问题,-p 后面输入的内容将有所不同) -p: 数据库管理员sq8xxxx的密码 (一般输入该密码) -p: 指定将使用的数据库名 而后 ,Enter password:在这里输入数据库的密码 (redhat 9.0版本) 在redhat 9.0版本下,如果 直接输入数据库管理员root的密码,将出现1045错误.对于上面提供的方法,在使用的过程中感觉麻烦,故停止验证。其实,还是一句话,版本兼容问题。在9.0下使用myisamchk 和 service mysqld start便可知道。 作者 zhangzhengxing bitsCN.com
