一个基于nodejs的Web Server程序： easy-pm

最近又有种造轮子的冲动，于是打算写一个 Web Server，用来在服务器上管理自己的小项目们。

需求如下：

• GitHub 自动化部署
  • 初始化及运行
  • 自动注册 Webhook
• 进程管理
  • 守护进程
  • 数据监控
  • 多核
  • 热重启
• 文件监听
• Virtual Hosts
• Automatic HTTPS
• HTTP/2 & SPDY

具体地说，就是希望创建一份类似下面的配置文件：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

{ "root": "/var/www", "port": 80, "ssl": { "port": 443, "auto": true }, "webhook": { "host": "http://hk.imsun.net", "token": "GitHubToken" }, "apps": [ { "name": "blog", "domains": ["imsun.net", "www.imsun.net"], "repository": "git@github.com:imsun/blog.git", "port": 8000 }, { "name": "gh-feed", "domains": ["gh-feed.imsun.net"], "repository": "git@github.com:imsun/gh-feed.git", "branch": "release", "port": 8001, "max_memory_restart": "100M" } ] }

然后服务器就会

1. 下载运行所有项目；
2. 注册监听 GitHub Webhooks；
3. 在 Let’s Encrypt 注册 SSL 证书；
4. 开启 HTTP/2 服务器，将流量按域名转发给各个项目；
5. 监控项目运行情况，在报错或资源占用超标时重启。

目前已经基本实现现有需求，未来看情况还可能会支持 NVM 和 Travis CI。
