1.MySQL8.0.11下載網址： https://dev.mysql.com/downloads/mysql/

2.配置環境變量：我的電腦->屬性->高級系統設置->環境變量->系統變量->Path：新增MySQL解壓文件中bin的路徑（D:\mysql-8.0.11\bin）

3.在解壓的文件夾（D:\mysql-8.0.11）中新建名為data的文件夾和名為my.ini 的文件，打開my.ini，寫入下面的配置：

[mysqld]
# set basedir to your installation path 設置解壓文件mysql文件夾的路徑（D:/mysql-8.0.11 -->將此處替換為自己的路徑）
basedir
 
=D:/mysql-8.0.11
# set datadir to the location of your data directory 設置剛才創建data文件夾的路徑（D:/mysql-8.0.11/data -->將此處替換為自己的路徑）
datadir=D:/mysql-8.0.11/data

4.安裝mysql，管理員身份打開cmd命令框切換到 D:\mysql-8.0.11目錄下輸入 :

D:\mysql-8.0.11>bin\mysqld --initialize-insecure
D:\mysql-8.0.11>bin\mysqld --install

5.啟動mysql，先切換到bin目錄下，然後輸入net start mysql (停止服務：net stop mysql)：

D:\mysql-8.0.11\bin>net start mysql
MySQL 服務正在啟動 .
MySQL 服務已經啟動成功。

6.登陸mysql並修改密碼（此方法安裝初始密碼為空，輸入 mysql -u root 即可登陸，修改密碼：alter user ‘root‘@‘localhost‘identified by ‘123456‘;）：

D:\mysql-8.0.11\bin>mysql -u root  
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id 
 
is 8
Server version: 8.0.11 MySQL Community Server - GPL

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

mysql> alter user ‘root‘@‘localhost‘identified by ‘123456‘;

至此，mysql數據路已安裝好了。

其他問題：

(1).遠程連接

a.是否關閉本機防火墻(或者開放3306端口，參考鏈接：https://blog.csdn.net/spt_dream/article/details/75014619）

b.可能需要重新設置修改密碼的方式，登陸mysql：

mysql> alter user ‘root‘@‘%‘identified with mysql_native_password by ‘12340‘;
Query OK, 0 rows affected (0.05 sec)
mysql> flush privileges;

c.是否需要授權，參考鏈接：https://www.cnblogs.com/skyWings/p/5952795.html
