1.下载mysql5.7
我这里下载的是mysql-5.7.32-winx64
2.解压文件夹
命名为:
D:softmysql57_host01
3.创建相应的目录
D:softmysql57_host01conf
D:softmysql57_host01data
D:softmysql57_host01
edolog
D:softmysql57_host01mysqlloginlog
D:softmysql57_host01mysqlloglogfile
D:softmysql57_host01mysqllog
elaylog
4.将mysql bin目录添加到环境变量
5.初始化
C:UsersAdministrator>mysqld --initialize --console --user=mysql --basedir=D:softmysql57_host01 --datadir=D:softmysql57_host01data --lc_messages_dir=D:softmysql57_host01share --lc_messages=en_US

7.安装mysql服务并启动
C:UsersAdministrator>mysqld.exe install MySQL --defaults-file="D:softmysql57_host01confmy.ini"
Service successfully installed.
C:UsersAdministrator>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
8.登录修改root密码
C:UsersAdministrator>mysql -h localhost -uroot -p
Enter password: ************
mysql> set password=password('mysql');
然后进行具体的修改
update mysql.user set authentication_string=password('mysql') where user='root' and host = 'localhost';
flush privileges;
9.创建开发用户
创建登陆用户
grant ALL on *.* to root@'%' identified by 'mysql' WITH GRANT OPTION;
