1.下载解压版mysql
mysql-5.7.18-winx64.zip
2.自定义安装路径
自己安装路径
F:\myinstall\mysql\mysql-5.7.18-winx64
3.手动在bin目录下创建my.ini文件
F:\myinstall\mysql\mysql-5.7.18-winx64\bin
3.1 修改my.ini文件
修改内容：
basedir =“F:\myinstall\mysql\mysql-5.7.18-winx64”
datadir =“F:\myinstall\mysql\mysql-5.7.18-winx64”\data”
tmpdir =“F:\myinstall\mysql\mysql-5.7.18-winx64”\data”
socket =“F:\myinstall\mysql\mysql-5.7.18-winx64”\data\mysql.sock”
log-error=“F:\myinstall\mysql\mysql-5.7.18-winx64”
innodb_data_home_dir=“F:\myinstall\mysql\mysql-5.7.18-winx64”\data”
将以上需要修改的内容改为自己安装的mysql路径即可

3.2创建data数据存储文件
在F:\myinstall\mysql\mysql-5.7.18-winx64目录下新建data文件夹，必须为空
4.配置mysql环境变量
5.使用系统管理员方式cmd到mysql安装路径
1.在电脑左边找到命令提示符
2.执行如下命令
mysqld.exe -install
mysqld --initialize-insecure
mysqld -install
6.win10开启自动启动mysql服务
进入mysql安装页面的bin目录下，输入“mysqld.exe –install”
可以看到输出结果为：
mysqld.exe --install
Service successfully installed.
7.启动mysql服务net start mysql
net start mysql
7.1查看mysql是否启动成功
7.2查看mysql是否启动成功
安装成功还没设置密码回车即可
Mysql5.7.18修改密码
7.1 进入mysql执行如下修改密码
update user set password=password("123456") where user="root";
update mysql.user set authentication_string=password('123456') where user='root';
mysql> select user from user;
+-----------+
| user |
+-----------+
| mysql.sys |
| root |
+-----------+
2 rows in set (0.00 sec)
mysql> update user set password=password("123456") where user="root";
ERROR 1054 (42S22): Unknown column 'password' in 'field list'# 修改报错
mysql> update mysql.user set authentication_string=password('123456') where user='root'; # 再执行修改成功
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 1
mysql> flush privileges; # 刷新权限
Query OK, 0 rows affected (0.00 sec)
mysql> quit;# 退mysql
Bye
C:\Users\jkl>
7.2 重新进入mysql
发现不输入密码，直接报错，输入密码后直接进入mysql了
C:\Users\jkl>mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
C:\Users\jkl>mysql -uroot -p
Enter password: ******
