mysql ERROR 1045 (28000): 错误解决办法
本文分析了mysql登录报错提示:ERROR 1045 (28000)的解决方法。分享给大家供大家参考,具体如下:
一、问题:
公司linux系统的mysql数据库root用户设置过密码,但常常用命令'mysql -u root -p'登录报错,有时又能登录。登录报错信息为:
1
2
3
|
[root@localhost ~] # mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root' @ 'localhost' (using password: YES) |
二、原因:数据库中存在空用户所致
三、解决方法:
1、停用mysql服务:
1
|
# service mysql stop |
2、输入命令:
1
|
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking & |
或
cd /etc/mysql/conf.d/
vim mysqld.cnf
cd /etc/mysql/mysql.conf.d/
vim mysqld.cnf
重启 service mysql restart
3、登入数据库:
1
|
# mysql -u root mysql |
4、
1
|
mysql> use mysql; |
5、
1
|
mysql> select user,host,password from user; |
结果如下:
+------+-----------------------+----------+
| user | host | password |
+------+-----------------------+----------+
| root | % | mima |
| root | localhost.localdomain | mima |
| root | 127.0.0.1 | mima |
| | localhost | |
| | localhost.localdomain | |
+------+-----------------------+----------+
6、将上面查询出来的空用户删除:
1
|
mysql> delete from user where user= '' ; |
7、退出数据库:
1
|
mysql> quit |
8、启动mysql服务:
1
|
# service mysql start |
9、重新用命令:
1
|
mysql -u root -p |
