3.在%mysql%/bin目录下运行cmd.exe

   执行 mysqld --initialize  对mysql进行初始化，在%mysql%目录下会生成data及mysql子目录

    mysqld remove是移除服务

5. 执行 net start mysql 启动mysql服务  net stop mysql 是停止服务

6.将%mysql%/bin目录添加到环境变量

7.修改root密码

   命令行执行：mysql –uroot -p

    输入空密码

   mysql> SET PASSWORD = PASSWORD(‘123456‘);

   mysql> ALTER USER ‘root‘@‘localhost‘ PASSWORD EXPIRE NEVER;

　　mysql> flush privileges;

8.远程登录配置

允许root用户在任何地方进行远程登录，并具有所有库任何操作权限，具体操作如下：

1）在本机先使用root用户登录mysql：

命令行执行：mysql -u root -p

输入密码（第7步中设置的密码）：123456

2）进行授权操作：

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

重载授权表：

mysql>FLUSH PRIVILEGES;

退出mysql：quit
