Cloudflare搭建属于自己的Git加速站

基于开源项目gh-proxy地址:–>点击访问
cloudflare地址:–>点击访问

搭建

1. 首先访问cloudflare注册一个你自己的账户
2. 然后点击workers
3. 之后弹出来这个界面，你需要在输入框中输入你自己的workers的名字
4. 请注意！一定要方便记忆，不要乱输，这个会出现在你的网址中
5. 输入好后点set up
6. 然后选择订阅模式，白嫖怪直接ree！
7. 免费版本每天的访问次数是10w次，应该是远远够用的！
8. 验证邮箱完成后刷新，点击创建

输入名称，直接点击 创建服务

然后点击快速编辑

点击保存并部署—再点击右上方 发送

显示如下就成功了：

配置域名加速workers

1. 域名下点击workers 点击右边添加路由

2. 第一个空输入 你的域名/*
3. 第二个选择你在主页workers里面创建的git加速的名字，你设置的什么就选什么！
4. 第三个只有一个选项，你就选它就行

5. 然后保存，保存之后是这样！

测试

直接访问你的域名，在没有魔法的情况下能否访问

经过测试，阿里服务器可以成功使用git clone命令

到此已经成功实现了域名无魔法访问workers!
