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

并在[mysql]下面加上skip-grant-tables，

這個用于跳過密碼問題，但是這并不能徹底解決。

2、重啟mysql服務

本人用的是Linux系統的Mysql，語句如下：

查看端口號：

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，剛才已經設置跳過密碼了可忽略

操作步驟如下：

[root@localhost ~]# mysql -uroot -p123456mysql> use mysqlDatabase changedmysql> 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: 0mysql> flush privileges;Query OK, 0 rows affected (0.03 sec)mysql> quitBye

OK，退出mysql，重啟mysql就解決問題了

前后對比一下：

[root@localhost ~]# mysql -uroot -pmysql> use mysql;Database changedmysql> 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!
