☆☆☆☆☆☆☆ 一.Windows7下配置免安装版Mysql5.7.21 ☆☆☆☆☆☆☆

 

• 5.手动新建相关文件夹/文件(文件内容为空即可)

F:\mysql-5.7.21-winx64\xudebiao 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  

• 6.新建my.ini配置文件

# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.

• 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~
