在linux平臺下使用mysql過程中忘記了root密碼，對于運維和DBA來講都是一件頭疼的事情，下面來講解下怎么進行重置mysql數據庫root 密碼：

1、首先停止mysql服務進程：

?1?service mysqld stop?

然后編輯mysql的配置文件my.cnf

1 vim /etc/my.cnf

找到 [mysqld]這個模塊：

在最后面添加一段代碼

1 skip-grant-tables ##忽略mysql權限問題，直接登錄

然后保存 :wq!退出

啟動mysql服務：

1 service mysqld start

直接進入mysql數據庫：

1 Starting MySQL. SUCCESS! 2 [root@web1 ~]# mysql3 Welcome to the MySQL monitor. Commands end with ; or \g.4 Your MySQL connection id is 15 Server version: 5.6.34 Source distribution6 7 Copyright (c) 2000, 2016, Oracle and/or its affiliates.

Other names may be trademarks of their respective 11 owners. 12 13 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. 14 15 mysql>

使用mysql表，然后進行修改mysql的root密碼：

1 mysql> use mysql; ##使用mysql數據庫2 Reading table information for completion of table and column names3 You can turn off this feature to get a quicker startup with -A4 5 Database changed6 mysql> update user set password=password("123456") where user="root";##更新密碼7 Query OK, 4 rows affected (0.00 sec)8 Rows matched: 4 Changed: 4 Warnings: 09 10 mysql> flush privileges;##刷新權限 11 Query OK, 0 rows affected (0.00 sec)

注意：先把mysql服務進程關閉,把添加過的跳過驗證信息刪除，要不然對數據庫安全威脅太大，
