仅个人记录，方便以后忘掉回来看看
服务器买的是腾讯云的，系统是 CentOS。
管理工具用的是万胜云面板（好像也叫宝塔），数据库都是在这里面整的，用到的表提前在里面创建好了

数据库管理脚本，提供的连接服务器，以及登录、注册功能
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class MySqlTest : MonoBehaviour
{
public Button SignIn;//登录按钮
public Button Register;//注册按钮
public Button Activation; //测试激活按钮
public InputField InputUser;//用户名输入框
public InputField InputPassword;//密码输入框
// Start is called before the first frame update
void Start()
{
//初始化
MySqlManager.Init();
//登陆，点击事件
SignIn.onClick.AddListener(()=>
{
MySqlManager.Instance.Click_login(InputUser.text, InputPassword.text);
});
//注册，点击事件
Register.onClick.AddListener(()=>
{
MySqlManager.Instance.Click_register(InputUser.text, InputPassword.text);
});
}
测试登录和注册的用户脚本
运行后的结果
