00:13大家好，这里是安格视界

00:27在上期视频，我分享了 OpenClaw 的各项能力，实战了一个网络版的中国象棋的项目，以及我认为的 OpenClaw 的最佳部署架构

00:41那本期视频就把上期视频的坑填上，完成 OpenClaw 的最佳部署架构的落地

00:55这是我上期视频的方案架构，有需要详细了解的同学，可以去翻看一下我上期视频

01:09本期视频将会详细分享：一，在虚拟机环境创建带桌面的 Ubuntu；二，在带桌面的 Ubuntu 里面部署 OpenClaw；三，OpenClaw 的详细配置，包括大模型的连接，API Key 或者 Oauth 认证，以及 Telegram 电报的连接

01:23最后会分享一些小技巧和指令

01:37那第一步，我就要在这台 Windows Server 2025 上安装虚拟机，简单看一下配置

01:52那它的 CPU 是双至强 E5 2680，总共有 20 核，然后动态有 40 核，已经启用了虚拟化

02:07内存是 128G，然后运行了一堆的影音服务器软件，还部署了一堆的 Linux 的服务器，跑各种原生的 Linux 服务和 Docker

02:22那首先，我们要 W i n d o w s 上启用 Hyper-V

02:38在 Win Server 上打开控制面板，然后程序和功能，再点击左边的启用或关闭 Windows 功能

02:53Windows Server 的话，它会打开服务器管理器，然后点开下一页，下一页勾上这个 Hyper-V，下一页，等它安装重启就可以了

03:08在其他的 Windows 平台也差不多，在 Win 11 上也是

03:23 打开控制面板，然后点程序，再点这个启用或关闭 Windows 功能，勾选 Hyper-V，确定，等它安装重启之后就可以了

03:54Hyper-V 安装好之后，有一个重要的步骤，就是要去设置一下它的网卡

04:25在 Hyper-V 里面，它叫虚拟交换机管理器，那在这里要选择外部，然后点击创建虚拟交换机，名字这里起一个好记的名字，下面，这里选择真实的能上网的物理网卡，点击下面的应用和确定，就能创建一个 Hyper-V 的虚拟网卡了

04:56那 ผม这里已经创建了两个虚拟网卡，然后我们要到 Ubuntu 的官网去下载一个 Ubuntu 桌面版的 ISO 镜像，点击这个 Download Ubuntu，然后 Download Ubuntu Desktop

05:27 那它目前最新的版本是这个，那它是X86架构的64位的系统，点击右边的Download，稍微等一会儿，就可以下载了

05:39那接下来，我们在Hyper-V里面创建一个带桌面的Ubuntu系统

05:50那如果你是其他的虚拟化平台，那也大同小异

06:02如果是PVE的平台，可以参考这期视频

06:14打开Hyper-V管理器，好，点击右边的“新建”，虚拟机

06:26我为了虚拟机的可管理性，我会把名字设置为IP，然后再加系统的名称，这样我看到他的名字，就知道他的IP是多少，他是干嘛用的

06:38好，下一页

06:50那虚拟机，肯定选择最新的一代

07:02那内存这里，带图形的Ubuntu，4G起步吧，最好是配到8G

07:13那我这里是演示，就选4G

07:25下一页

07:37那网络这里，我们就选择刚 才创建好的外部的虚拟网卡，好，下一页

07:49那磁盘，这里就要注意一下磁盘空间的大小，那我这里就用它的默认值127G，好，下一页

08:09这里就要选择光驱，然后选择我们刚才下载好的带桌面的Ubuntu镜像，好，打开

08:30在下一页，再点击完成，虚拟机创建好了

08:51我们还要再点击一下右键设置，到安全，把安全启动关掉，再到处理器，它默认给的核心太多了，给它改成8个，那你们要根据自己的CPU的核心来改，要留有一定的冗余，应用，确定

09:11这样虚拟机才算是创建好了

Set the hostname echo "Setting hostname 到这里就选择语言，那我这里就选择简体中文，下一步，再下一步，键盘已经自动检测出来了，不改了，下一步

09:50那网络这里我们设置好了，虚拟网卡，就选择有线网络，下一步

10:08这里肯定选择安装Ubuntu，下一步

10:26那这里选择交互式安装，下一步

10:45这里全部跳过，下一步

11:03选择擦除磁盘并安装，下一步

11:21这里就要输入你的名字以及主机名，用户名，密码，保持这个登录时需要密码的勾选，下一步

11:40选时区，它会自动定位，那这里它定位到东八区，没问题，下一步

11:58好，准备工作都完成了，点击安装

12:16这个安装的过程会比较漫长，需要耐心等待一下

12:34点击这个图标，可以查看一下具体的进度

12:53等了将近有50分钟，看到这个界面就安装完成了，点击立即重启，稍微

13:11 一会儿，虚拟机开始重启，那它这里提示，先移除安装的媒体，然后按回车，直接回车，好，看到登录界面了，点击这个用户名，输入密码，回车，好，进入桌面了，它会有个引导，点击前进，跳过这个Ubuntu Pro，这里就无所谓了，前进，好，完成，然后点击它的开始菜单，点击设置，默认就是网络设置，既然是做服务器，我们要把它的IP地址改成静态IP，点击这个小齿轮，到IPV4，改为手动输入，静态的IP地址，要在的局域网的IP地址段里面，不要有冲突就行了，分别输入正确的IP地址，子网掩码，网关，还有DNS，好，点击应用，接下来我们要打开它的远程访问能力，拖到下面，系统，远程桌面，再打开桌面共享，远程控制，改一个你 知道的密码，返回，然后可以找一台局域网内的随便一台电脑，打开远程桌面，输入刚才的IP，点击连接，然后选择刚才的账号和密码，点击确定，好，不再询问，点击是，好，进到桌面了

13:24那以后就可以通过远程桌面来控制这台带桌面的Ubuntu系统

13:37那接下来，我们要在这台系统上安装一个Chrome浏览器

13:50我们打开它内置的Firefox，直接输入Chrome，让它搜索

14:03那这里就要有全局的上外网的环境，然后打开Chrome的官网

14:16那所谓全局上外网，就是配置软路由，让整个局域网来上外网

14:29那做过很多视频，大家可以到我的YouTube主页上去刨一下

14:42那这里就直接下载Chrome，然后选择第一项，.deb的格式，然后接受

14:55 然后它就会开始下载，下载完成之后，双击，然后点击安装

15:08好，安装，输入密码，稍等一会儿，等它安装好，安装完成，关掉

15:20再打开显示应用，可以看到 Chrome 就已经安装好了

15:32然后把它固定到快捷栏，我们把终端也固定到快捷栏

15:44为了让以后远程桌面的操作体验更好，我们还需要做一下设置

15:56点击设置，然后到隐私与安全，再到锁屏，记得这里把自动锁屏给它关掉

16:07然后息屏的时间设为永不

16:19由于 Hyper-V 的剪贴板没有对 Linux 虚拟机开放，所以接下来我们直接用远程桌面来连接这台带桌面的 Ubuntu 系统，完成后面的设置

16:31好，输入用户名和密码，然后点击确定

16:43好，这就连接上了

16:54现在打开 Chrome，然后搜索 OpenClaw，然后打开OpenClaw的官网，再往下拖，这里有Quick Start，可以看到默认的是MacOS和Linux的安装指令，复制下来，然后打开终端，可以调整一下它显示的行数和列数

17:17Ctrl + Shift + V给它粘贴进去，回车系统里面没有cURL的话，它也会提示安装cURL的指令，那就安装一下cURL，用方向键向上调出之前安装OpenClaw的指令，回车，然后等待它安装好

17:40出现这个说明就安装成功了，接下来要进行配置，这里有个风险提示，选择Yes，这里就选Quick Start，直接回车

18:03这里要选AI的供应商和模型，那很多人没有大厂的模型，实际上OpenClaw支持…… 支持第三方的模型，我们就先配置第三方的模型，一直往下拉，选择 Custom 这个

18:26这里要输入 Base URL，就是 API 接口的网址

18:45那这个，大家可以打开芝麻开门的官方网站，去注册一个账号，然后把这个网址复制下来，再回到 OpenClaw 的配置界面，把光标移动前两格，前面的全部删掉，然后 Ctrl + Shift + V，粘贴，把多余的斜杠去掉，回车

19:03这里要输入 API Key，还是打开 Opendoor，芝麻开门的官网，要登录进去，在令牌管理这里，可以添加令牌

19:22那，我这边已经添加好了，就直接复制，再回到 OpenClaw 的配置界面，然后 Ctrl + Shift + V，粘贴，回车

19:40然后这边就选择第一个，OpenAI 的兼容模式

19:58这 里面要输入模型的ID，这个ID不能乱填

20:17那我们还是打开芝麻开门的官网，然后到它的模型广场，他们GPT-4.1-mini，这个模型很稳，且价格也是底价

20:35那就先配置这个模型，然后点击右上角的复制，再回到OpenClaw的配置界面，然后Ctrl+Shift+V，粘贴过去

20:36之后它会验证，这样这个接口和模型配置就成功了

20:36这里要给这个接口命名，叫OpenDoor，这里是给别名，就不用了

20:37直接回车，这里是配置Channel，就是通道

20:37其实它直接改名叫客户端，更容易理解一点

20:38那这个作者也强烈建议用Telegram电报，那就这样了

20:38回车，这里要输入机器人的token，那这里我们要去找，机器人他爹，好

20:39 Ctrl+Shift+C，把这个复制下来，然后打开电报，粘贴，搜索这个机器人他爹，这里输入斜杠，然后选择第一个，创建一个新的机器人，那这里要给这个机器人命名，那自己好记就可以了，这里要给机器人命名一个ID，那这个要复杂一点，按这个格式，因为这个ID它是唯一的，不能重复，出现这个提示，说明机器人就创建成功了，我们把中间这串码给它选中，复制下来，然后回到OpenClaw的配置界面，然后在里，Ctrl+Shift+V，粘贴，好，channel，电报就配置好，这里是配置Skills技能，可以后面慢慢配，先跑通再说，选择no，回车，我们这里也不配置钩子，好，skip，这里是按什么方式来启动，那我们 们是带桌面的Ubuntu，所以可以选择第二项

00:00在本地打开浏览器，那上面已经提示Chrome已经打开了OpenClaw的管理地址，点击之后就可以直接打开这个OpenClaw的管理地址

00:00那回到OpenClaw的配置界面，它就配置完成了

00:01那我们直接输入这串指令来查看一下OpenClaw的状态，结果它返回没有找到这个命令

00:01没关系，我们把从安装到最后一行全部选中，Ctrl+Shift+C，所有都复制下来

00:02随便找一个AI工具，那我自己找的是Cherry Studio，然后+芝麻开门的API接口，选择的就是gpt-4.1-mini这个白菜价格的模型，然后把刚才复制的信息全部粘贴到这里，发送给 他的模型反应速度还是很快的，我们找到它的解决方案关键信息，给它复制下来，再回到OpenClaw的配置界面，Ctrl+Shift+V，粘贴，回车

00:02再来检查一下OpenClaw的状态，好，它执行完成了

00:03看不懂没关系，我们把执行这条指令开始到最后，全选，Ctrl+Shift+C，复制，再打开Cherry Studio，Ctrl+V，给它粘贴，然后发给他

00:03然后他会给你分析他的状态以及总结

00:04那现在说明OpenClaw的状态是良好的，没有问题

00:04那我们回到电报，把这个机器人的ID复制一下，然后粘贴

00:05好，查找出来了，然后点击开始

00:05那这里它提示我们电报没有配对

00:06那现在还是把它们全部选中复制，打开Cherry

00:06 Studio 粘贴，然后找到他的方案的关键信息，复制，这个就是OpenClaw配对Telegram的指令

00:07然后再到Ubuntu的终端，Ctrl+Shift+V，粘贴

00:07那长这样，那说明配对就成功了

00:08回到Telegram，随便打点东西，回车

00:08那它这里返回上下文的长度不够，那这个是接第三方接口的通用问题，我们现在解决它

00:09回到Ubuntu的桌面系统，打开OpenClaw的后台管理地址，它还是个中文界面，到配置，然后点raw，刚才配好的配置信息都在这里

00:09找到context window这一行，将后面的4096改成20000

00:10将下面这一行max tokens改为8000

00:10再点击右上角的save和update

00:11再回到 电报试一下，好，还是不行

00:11我们再回到终端，输入这串指令，让 OpenClaw 网关重启一下

00:12结果路径又丢了，我们再执行刚才这两行，把路径添加进去

00:12检查一下 OpenClaw 的状态，好，说明 OpenClaw 的路径已经添加进去了

00:13再让网关重启一下，再回到电报测试一下，好，它已经能正常的响应了

00:13那这里我们可以输入/status，它这里就会返回 OpenClaw 的版本，以及使用模型的一些信息

00:14那可以看到，我这里用的就是 Opendoor 的 GPT-4.1-mini 这个模型

00:14当然 OpenClaw 支持多厂家多模型，我们可以指定不同的任务，通过不同的模型来完成，非常灵活

00:15接下来我们就来给它配上原厂的模型，我们还是回到 Ubuntu 的终端输入这串指令回车，来进行配置

00:15这里就选择本地机器

00:16这里就选择第二个，模型，回车

00:16我们先来配置 MiniMAX 的模型，这也是 OpenClaw 作者推荐的国产模型

00:17选择 MiniMAX，回车

00:17这里 MiniMAX 认证的方式要注意一下，因为 MiniMAX 分国际站和国内站

00:18如果是国内站，要选择第三个，MiniMAX M2.5 CN，就是在 MiniMAX.com 这个网站注册的账号

00:18选中回车

00:19这里就要输入 MiniMAX 的 API Key，就是在 MiniMAX 的网站注册充值，然后创建一个 API key，再把这个 key 粘贴到这里，回车

00:19这里就选模型，那就选这个 MiniMAX 2. 直接回车，好，到这个界面，我们再来配置一下另外一种认证方式

00:20如果我们开通了 OpenAI 的会员，哪怕是 ChatGPT Go，一个月只需要 8 美金，都可以用得很好，因为它可以通过 OAuth 认证，就是网页认证的方式，无需额外付费，OpenClaw 就能用

00:20当然它也有缺点，就是会限流

00:21那现在我们就来配置一下 OpenAI 的 OAuth 认证

00:21选择 model，继续回车

00:22好，OpenAI，回车

00:22那它这里有两种连接方式，第二种就是常用的 API-Key 的方式，那这种连接方式和刚才操作的 MiniMAX 几乎是一致的

00:23那我们现在要配置的是 OpenAI 的网页认证，就选第一个 OpenAI Codex，回车

00:23那上面它提示 已经打开了网页

00:24好，我们点击一下

00:24这里就要登录 ChatGPT

00:25那我的 ChatGPT 是用 Gmail 的账号，所以，我这里选择使用谷歌登录

00:25那你们是用什么方式注册的 ChatGPT，就用什么方式登录

00:26这里肯定选择继续

00:26这里提示就已经认证成功了

00:27回到这里，他就可以直接选模型了

00:27这里的体验应该是没有做好，他将所有厂家的模型全部列出来了

00:28那还好，直接打字可以筛选模型

00:28那比如我这里输入 GPT-5.3，那这个范围就小多了

00:29那这里它支持多选，按空格就可以选中

00:29那这里我就选中两个 5.3 Codex 的模型，然后修改关键词，再选择两个 5.2 的模型

00:30模型选好之后就回车

00:30这里选择最后一个，continue，回车

00:31那这里模型的 配置就完成了，现在我们打开电报来验证一下，输入/mo，它就会将相关的指令列出来，那选择Models继续，那可以看到，刚才添加的模型，厂家都生效了，有MiniMAX-C，OpenAI分了两个，一个是OpenAI和OpenAI-Codex，还有就是最初配置的opendoor，芝麻开门的接口，好，看一下OpenAI，那里面有两个模型，看一下OpenAI-Codex的模型，有一个MiniMAX，有一个已经添加进去了，是选中状态，表示当前的模型就是这个，我们输入/status来查看一下当前模型的状态，那当前的模型就是MiniMAX 2.5，那随便打点内容来测试一下这个模型可不可用，好，它已经正 常回复，没有问题，说明这个模型的配置是正常的

00:31我们再输入/models来切换模型，再验证一下

00:32那这里选择OpenAI的端点，然后选择GPT 5.2的模型

00:32好，那现在它提示模型已经设置为GPT 5.2

00:33我们再测试一下，它还回复已经切换到了GPT 5.2了，那说明GPT 5.2的模型的设置也没问题

00:33我们再来验证一下Codex的模型是否正常

00:34好，也没有问题

00:34再确定一下当前选择的模型，确实是我们刚才选中的GPT 5.3 Codex

00:35我们维护好厂家之后，以后要添加新模型就变得异常简单

00:35那比如像opendoor这样的第三方的AI API接口，它有许多的模型

00:36那刚才我们也只给它配置了一个模型，就是GP T4.1 mini，那现在我要给OpenClaw添加一个新的模型，好，打开opendoor的官网，然后到它的模型广场，找到一个可用的模型，那比如就这个GPT 5.1，给它复制一下，然后回到电报，然后直接告诉他，让他添加opendoor的GPT 5.1的模型，那这里的GPT-5.1，我是直接粘贴刚才复制的模型ID，那它很长时间没有输出，那我们直接来验证一下，输入/models，可以看到opendoor已经有两个模型了，一个是GPT 4.1 mini，另一个是新添加的GPT 5.1，好，我们选中这个GPT 5.1，好，现在模型已经切换过来了，好，现在来验证一下，等一Дан время он выдаст результат, что означает, что Open 这个GPT 5.1的模型我们配置成功了，而且这个模型是有效的，可以再次验证一下，当前模型的选择，好，那确实用的是opendoor的GPT 5.1的模型

00:36好，现在我们从Ubuntu桌面版的安装，到OpenClaw的安装以及详细的配置，电报的连接，以及多厂家多AI模型的配置，到这里就全部结束了

00:37最后解决一个烦人的问题，就是我们通过远程桌面RDP去连接桌面版的Ubuntu的时候，每次都要输入密码

00:37我们打开控制面板，然后找到用户账户，然后管理Windows凭据，那可以看到，我这里已经添加了Ubuntu桌面版的Windows凭据，只需要在这里添加Windows凭据，输入Ubuntu桌 面的IP地址，用户名和密码，确定就可以了

00:38然后打开远程桌面，直接连接，就不需要再输入用户名和密码了
