[Goodbye node-forever, hello PM2][pm2] [pm2]: (http://devo.ps/blog/2013/06/26/goodbye-node-forever-hello-pm2.html)
看了工具的介绍, 觉得蛮方便的, 就是不支持 CoffeeScript 让人有点抓狂:
Github: https://github.com/Unitech/pm2
npm install -g pm2
特点
PM2 觉得 Forever 有一些不好用的地方:
- log 和监视的功能有限
- 进程和集群管理有限
- Aging codebase (升级 Node 容易导致应用失败)
目测比 Forever 好用一些… PM2 是前几个月刚写的, 还不完善: 列出来的计划有:
- Remote administration/status checking,
- Built-in inter-processes communication channel (message bus),
- V8 GC 内存泄露检测,
- Web 界面,
- Persistent storage for monitoring data,
- 邮件通知
Demo
盗链个截图:
然后本地安装尝试了一下:
➤➤ cat a.js
// Generated by CoffeeScript 1.6.3
require('http').createServer(function(req, res) {
return res.end('ok');
}).listen(3000);
➤➤ pm2 start a.js
⌬ PM2 Configuration : { script: 'a.js', name: 'a' }
⌬ PM2 You can write the current configuration by adding -w option

在Windows 7下一次就安装成功，爽了一下，于是运行看看：

多么痛的领悟…
