Windows10 安装 MySQL8 并开启远程访问

首先去官网下载MySQL8

https://dev.mysql.com/downloads/windows/installer/8.0.html

我是解压到C:\mysql-8.0.12-winx64

然后配置环境变量：

变量名：MYSQL_HOME

变量值：C:\mysql-8.0.12-winx64

在Path变量值最前面添加：

%MYSQL_HOME%\bin;

以管理员权限打开CMD，切换到C:\mysql-8.0.12-winx64\bin目录

使用下面的命令进行安装：

mysql install 

使用下面的命令启动MySQL：

net start mysql 

然后使用下面的命令连接MySQL：

mysql -u root -p

提示需要输入密码的时候直接回车

C:\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.

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

登陆成功之后修改密码（密码修改为admin）：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'admin';

默认不允许远程访问MySQL，下面是开启远程访问的命令：

use mysql;

update user set host = '%' where user = 'root';

FLUSH PRIVILEGES;
