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
並在[mysql]下面加上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 -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
前后對比一下：
[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！
