MySQL下载与安装
进入mysql官网，找到社区版MYSQL下载地址：https://dev.mysql.com/downloads/

使用管理员身份打开cmd，并cd到bin目录下，进行初始化数据库存储文件：mysqld.exe --initialize --console
问题：安装的时候提示data目录已经存在——data目录是存储数据的目录
解决方式：1 删除data目录。2 初始化数据库存储文件时，制定一个配置文件其中data目录制定一个空目录。
对于初学者建议直接删除data目录：
删除data目录后，重新执行命令如下图：mysqld.exe --initialize --console
（A temporary password is generated for root@localhost: ojEOpe9#eXX-）
注意：其结果中生成了root账户的默认密码，需要记住后使用。
创建mysql的Windows服务：
mysqld.exe -install
删除mysql服务：
mysqld.exe -remove mysql
启动服务命令：
net start mysql
停止服务命令：
net stop mysql
登录和修改密码
上面安装时创建的root用户密码是零时密码，需要在有效期内修改。过期会导致问题。
cmd下等mysql： mysql -uroot -ppassword
mysql -uroot -p16tfDtkgQ5#X
mysql -uroot -pojEOpe9#eXX-
登录后修改密码：ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘自己想要设置的新密码’;
alter user ‘root’@‘localhost’ identified by ‘root’;
(set user name and password the same as root)
alter user ‘root’@‘localhost’ identified by ‘’;
