MySQL密碼正確卻無法本地登錄-1045 Access denied for user 'root'@'localhost' (using password:YES

MySQL密碼正確卻無法本地登錄

報錯如下：

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

解決方法：
1、在啟動mysql的參數中加入跳過密碼問題方式，如下：
vim /etc/my.cnf
併在[mysql]下麵加上skip-grant-tables，
這個用於跳過密碼問題，但是這並不能徹底解決。

2、重啟mysql服務

本人用的是Linux系統的Mysql，語句如下：

查看埠號：

ps aux|grep mysqld

查看狀態：

systemctl status mysqld

重啟mysql服務

systemctl restart mysqld

嘗試連接：

mysql -uroot -p123456

輸入密碼，剛纔已經設置跳過密碼了可忽略

操作步驟如下：

[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，重啟mysql就解決問題了

前後對比一下：
[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 |

OK!

gook luck！
