F:\mysql-5.7.21-winx64\xudebiao\data

F:\mysql-5.7.21-winx64\xudebiao\log

F:\mysql-5.7.21-winx64\xudebiao\log\mysql-error.log

F:\mysql-5.7.21-winx64\xudebiao\tmp

F:\mysql-5.7.21-winx64\xudebiao\tmp\mysql.sock

• 7.准备工作做好的截图

 

 

 

 

 

 

 

 

 

 

• 8.执行安装命令

管理员身份运行"命令提示符"

进入F:\mysql-5.7.21-winx64\bin

第一步执行初始化操作: mysqld --initialize-insecure

第二步执行安装服务操作: mysqld install

第三步启动mysql服务: net start MySQL

【正常情况下这里会直接提示成功。如果失败了，上面第5步清空data（F:\mysql-5.7.21-winx64\xudebiao\data ）目录，再次执行命令】

 

• 9.修改初始密码

mysql -u root -p

第一次登陆没有密码, 输入密码的时候直接回车

 

 

set password = password('1990xxxx');

 

• 10.登陆测试

 

 

• 11.确认编码格式utf8

show variables like '%character%';

 

 

好了, 可以开车上路了~
