MySql的root密码忘记该怎么找回

大家好,又见面了,我是你们的朋友全栈君。
Windows 下如果MySQL密码忘记了root密码导致无法登录,如下图所示,
这个时候怎么办,只能重置root密码了。
1.打开任务管理器查看MySql服务是否启动,如果已启动则先将其停止
2.找到MySql目录下的my.ini文件
3.打开该文件,找到里面的[mysqld],然后在这个下面添加skip-grant-tables,添加完后保存文件
4.重新进到任务管理器将MySQL服务启动起来
5.以管理员身份运行cmd
注意这里必须以此方式用管理员身份运行cmd,不能用win+R输入cmd运行,否则会出现 “’mysql’ 不是内部或外部命令,也不是可运行的程序或批处理文件”的错误。
6.输入mysql -u root -p就可以不用密码登录了,出现password:的时候直接回车可以进入。
7.进入mysql数据库:
mysql> use mysql;Database changed
8.给root用户设置新密码:mysql> update user set password=password(“123456″) where user=”root”;
提示:Query OK, 1 rows affected (0.04 sec)Rows matched: 1 Changed: 1 Warnings: 0
PS:123456为新密码,用户可根据自己需要修改成自己的密码
9.打开之前的my.ini文件将添加的”skip-grant-tables“这行删除
10.打开任务管理器重启MySQL服务。接着我们就可以用刚设置的密码 “123456”连接数据库了。
Mysql的root密码修改成功!
补充说明!!!
最后一步update user set password=password(“root”) where user=”root”; 只适用于5.5版本; 5.7版本要把第一个password字段改成authentication_string; 结果为update user set authentication_string=password(“123456″) where user=”root”
