二、另外需要注意的是Windows路径一定要用\\，这样mysql的数据库信息数据就被灌入data目录下。
参照菜鸟教程：https://www.runoob.com/mysql/mysql-install.html的步骤
一、使用Windows的管理员cmd进行操作
解压目录：默认8.0MySQL不提供my.ini文件了，需要自己创建。
my.ini
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[mysqld]
# 设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:\\software\\mysql-8.0.16-winx64\\bin
datadir=D:\\software\\mysql-8.0.16-winx64\\data
# 设置 mysql数据库的数据的存放目录，MySQL 8+ 不需要以下配置，系统自己生成即可，否则有可能报错
# 允许最大连接数
max_connections=100
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB开始安装：
cmd管理员，记得记录下随机密码，不要忽略掉，在cmd中用鼠标选中随机密码，然后右键点击其他地方一下，即复制下来了然后保存到一个文档中，等待接下来登陆MySQL以及修改初始密码。
C:\Windows\system32>d:

MySQL 服务正在启动 .
MySQL 服务已经启动成功。二、另外需要注意的是Windows路径一定要用\\，这样mysql的数据库信息数据就被灌入data目录下。
三、修改用户名密码：
use mysql;
UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
FLUSH PRIVILEGES;
quit
mysql -uroot -p修改密码的方式学习：https://blog.csdn.net/belug/article/details/81081040
更改加密方式尝试：
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;或者
alter user 'root'@'localhost' identified with mysql_native_password by 'amp';mysql -h localhost -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';修改初始密码、修改成远程登陆记录（亲测）
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> use mysql
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> use mysql;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.01 sec)
mysql> update user set host='%' where user='root';
ERROR 1046 (3D000): No database selected
mysql> use mysql;
Database changed
mysql> update user set host='%' where user='root';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql>
四、修改远程连接
mysql> use mysql
Database changed
mysql> update user set host='%' where user='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 1 Changed: 0 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.07 sec)五、忘记密码怎么办？
