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

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)
