如何把游戏挂到云服务器

一、技术介绍

将游戏挂到云服务器，可以实现远程访问和多人联机等功能，本文将介绍如何使用Python的`pycloudmessenger`库和`paho-mqtt`库来实现这一功能，首先需要安装这两个库：

pip install pycloudmessenger paho-mqtt

接下来，我们将分为以下几个步骤进行：

1. 创建一个云服务器；

2. 在云服务器上安装并配置`pycloudmessenger`库；

3. 编写一个简单的Python脚本来启动`pycloudmessenger`服务；

4. 将游戏代码部署到云服务器上；

5. 在本地计算机上运行Python脚本，实现远程访问和联机功能。

二、创建云服务器

这里以阿里云为例，创建一个ECS实例(弹性计算服务)，登录阿里云官网，选择ECS产品，按照提示完成购买和配置，购买完成后，会得到一个公网IP地址和登录凭证。

三、在云服务器上安装并配置`pycloudmessenger`库

1. 使用SSH工具连接到云服务器；

2. 执行以下命令安装`pycloudmessenger`库：

pip install git+https://github.com/Esri/pycloudmessenger.git

3. 创建一个名为`messaging_settings.json`的配置文件，内容如下：

{
  "project": {
    "name": "your_project_name",
    "namespace": "your_namespace"
  },
  "agent": {
    "operationMode": "pushAndPull",
    "taskWorkerPoolSize": "1",
    "taskDispatcherConfiguration": {
      "COORDINATOR": "your_project_name.your_namespace.coordinator",
      "TASKROUTER": "your_project_name.your_namespace.worker"
    },
    "transportSettings": {
      "IPCEndpointName": "your_project_name.your_namespace",
      "TCPPort": "5700"
    }
  }
}

4. 将配置文件上传到云服务器上的指定目录，例如：`/etc/pycloudmessenger/`;

5. 在云服务器上创建两个Python脚本：`coordinator.py`和`worker.py`,内容分别如下：

```python# coordinator.py
