4.编辑my.ini,修改basedir 和 datadir
四 、安装MySQL
注意说明:如果已安装,卸载掉之前老版本,命令:1、mysqld -nt-remove 移除
1、管理员运行cmd,进入bin目录
2、生成初始化密码
1
|
mysqld --initialize --console |
3、执行第二条命令,安装mysql服务
1
|
mysqld --install mysql |
4、启动mysql服务 命令启动:net start mysql
五、修改root 密码
1.在MySQL安装目录下的bin目录下,启动cmd,进入命令提示符后执行以下命令
2.修改root密码为:123456
1
|
ALTER USER 'root' @ 'localhost' IDENTIFIED BY '123456' ; |
3. 创建新的管理员账号
1
|
create user 'admin' @ 'localhost' identified by 'admin' ; |
4. 授权管理员账号
1
2
|
GRANT ALL PRIVILEGES ON *.* TO 'admin' @ 'localhost' ; FLUSH PRIVILEGES; |
5. 使用管理员账号登录
二、常见问题(不能通过ip连接到数据库)
解决办法:1修改访问权限即可。
