MySQL密码正确却没法本地登陆-1045 Access denied for user 'root'@'localhost' (using password:YES

MySQL密码正确却没法本地登陆

报错以下：

ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: YES)

解决方法：
一、在启动mysql的参数中加入跳过密码问题方式，以下：
vim /etc/my.cnf
并在[mysql]下面加上skip-grant-tables，
这个用于跳过密码问题，可是这并不能完全解决。

二、重启mysql服务

本人用的是Linux系统的Mysql，语句以下：

查看端口号：

ps aux|grep mysqld

查看状态：

systemctl status mysqld

重启mysql服务

systemctl restart mysqld

尝试链接：

mysql -uroot -p123456

输入密码，刚才已经设置跳过密码了可忽略

操做步骤以下：

[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

先后对比一下：
[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 |
