MySQL密碼正確卻沒法本地登陸-1045 Access denied for user 'root'@'localhost' (using password:YES

MySQL密碼正確卻沒法本地登陸

報錯以下：

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

解決方法：
一、在啓動mysql的參數中加入跳過密碼問題方式，以下：
vim /etc/my.cnf
並在[mysql]下面加上skip-grant-tables，
這個用於跳過密碼問題，可是這並不能完全解決。

二、重啓mysql服務

本人用的是Linux系統的Mysql，語句以下：

查看端口號：

ps aux|grep mysqld

查看狀態：

systemctl status mysqld

重啓mysql服務

systemctl restart mysqld

嘗試鏈接：

mysql -uroot -p123456

輸入密碼，剛纔已經設置跳過密碼了可忽略

操做步驟以下：

[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，重啓mysql就解決問題了

先後對比一下：
[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 |
+------+-----------------------+-------------------------------------------+
4 rows in set (0.00 sec)

mysql> 
OK!
