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: ******
