初始化密码查找:
如果data文件夹已经存在,先删除后,再执行以下:
mysqld --initialize --console
可以看到控制台输出有以下:
A temporary password is generated for root@localhost: hjd/Qg=XN4D*
在安装目录下生成 data文件 不用自己创建。
执行 mysqld -install 安装mysql数据库
(如果不用管理员身份运行,将会因为权限不够而出现错误:Install/Remove of the Service Denied!)
执行时一定要在bin目录底下(或者把bin层级的路径添加到path环境变量中)
net start mysql 启动服务(需要管理员权限)
net stop mysql 关闭服务。
启动成功以后
输入 mysql -u root -p
Enter password: --------------上述临时密码
直接回车就行
接下来设置自己的密码
set password=“你的密码”
查看一下默认安装的数据库
show databases;
