mysql密码设置与更改

最近将之前的Mysql数据库5.5更改到最新的5.7,然后需要设置密码,连接navicat,配置项目完之后,在运行时遇到一些问题,下面分享给大家,以此为鉴。


首先要以管理员的身份启动cmd,输入一下命令:net stop mysql 停止运行的mysql

打开一个cmd窗口输入mysqld --skip-grant-tables,注意这个cmd命令窗口不要关闭

重新打开一个cmd窗口,运行下面命令

C:\Users\Administrator>mysql

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 4

Server version: 5.7.19 MySQL Community Server (GPL)

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


mysql> use mysql

Database changed

mysql> update user set authentication_string=password('123456') where user='root';

Query OK, 0 rows affected, 1 warning (0.06 sec)

Rows matched: 1  Changed: 0  Warnings: 1

mysql>

将mysql的root密码重置为123456


继续以管理员身份运行cmd,输入net start mysql

启动MySQL服务

以重置后的root密码登录测试,如下图

mysql -uroot -p123456


到这里之后去编辑器中运行程序应该会报错( The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement),解决方法:

这个时候我们只需要
flush privileges 一下就OK了,
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
