- 1.下载安装包
- 2.解压到本地目录
F:\mysql-5.7.21-winx64
- 3.新增mysql环境变量
MYSQL_HOME = F:\mysql-5.7.21-winx64
- 4.修改Path环境变量
Path变量下,末尾新增 ;%MYSQL_HOME%\bin;
- 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

# *** 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~
