MySQL密码正确却无法本地登录-1045 Access denied for user 'root'@'localhost' (using password:YES

mysql密码正确却无法本地登录

报错如下：

error 1045 (28000): access denied for user ‘root‘@‘localhost‘ (using password: yes)

解决方法：
1、在启动mysql的参数中加入跳过密码问题方式，如下：
vim /etc/my.cnf
并在[mysql]下面加上skip-grant-tables，
这个用于跳过密码问题，但是这并不能彻底解决。

2、重启mysql服务

本人用的是linux系统的mysql，语句如下：

查看端口号：

ps aux|grep mysqld

查看状态：

systemctl status mysqld

重启mysql服务

systemctl restart mysqld

尝试连接：

mysql -uroot -p123456

输入密码，刚才已经设置跳过密码了可忽略

操作步骤如下：

[root@localhost ~]# mysql -uroot -p123456
mysql> use mysql
database changed
mysql> select user,host,password from user where user='root';
+------+-----------------------+-------------------------------------------+
| user | host | password |
+------+-----------------------+-------------------------------------------+
| root | % | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | localhost.localdomain | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | 127.0.0.1 | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | ::1 | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
+------+-----------------------+-------------------------------------------+
4 rows in set (0.02 sec)

mysql> update user set host='localhost' where user='root' and host='%';
query ok, 1 row affected (0.01 sec)
rows matched: 1 changed: 1 warnings: 0

mysql> flush privileges;
query ok, 0 rows affected (0.03 sec)

mysql> quit
bye
ok，退出mysql，重启mysql就解决问题了

前后对比一下：
[root@localhost ~]# mysql -uroot -p
mysql> use mysql;
database changed
mysql> select user,host,password from user where user='root';
+------+-----------------------+-------------------------------------------+
| user | host | password |
+------+-----------------------+-------------------------------------------+
| root | localhost | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | localhost.localdomain | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | 127.0.0.1 | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
| root | ::1 | *00a51f3f48415c7d4e8908980d443c29c69b60c9 |
+------+-----------------------+-------------------------------------------+

mysql> 
ok!
