今天，在新裝的mysql上限制只能通過127.0.0.1登錄之後怎麽也登錄不上。

1.在my.cnf最後一行(或者mysqld下面)設置跳過密碼驗證的過程（windows是my.ini）

skip-grant-tables

2.重啟mysql服務

service mysqld restart

3.直接輸入mysql即可

[root@VM_0_12_centos ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id 
 
is 1313
Server version: 5.6.41 MySQL Community Server (GPL)

Type ‘help;‘ or ‘\h‘ for
 
 help. Type ‘\c‘ to clear the current input statement.

4.修改密碼:

update user set Password=PASSWORD("newword") where user=‘root‘;

5.使修改生效

flush privileges;

6.修改完之後記得去掉跳過密碼驗證的設置，修改/etc/my.cnf去掉設置

7.正常使用即可
