mysqld --initialize -
Installation service
mysqld instal MySQL57
If the installation is unsuccessful, you can check whether the server has been installed through the command, and if it is deleted through the command, proceed with the installation
sc query mysql(service name)
sc delete mysql(service name)
Other problems can arise if the command mysqld --consolefor more information.

6. Configure the database
配置数据库做两件事情：修改root默认密码；设置root可以远程访问；
1.登陆：mysql -uroot -p
初始密码在data文件夹中以.err结尾的文件中，如：A temporary password is generated for root@localhost: =&Oifq2Nugk;
2.修改默认密码：alter user root@localhost identified by '123456';
3.切换数据库：use mysql;
3.设置用户可以远程访问（%表示不限制访问ip）：update user set host = '%' where user = 'root';
4.确认设置（或重启服务器让设置生效）：FLUSH PRIVILEGES;
- Service: System background process
* Start service: net start mysql
* Stop service: net stop mysql
The above is to complete the installation of the MySQL server
Note: sql statement must add a semicolon
