有人用 pandora.js 管理egg.js项目的嘛
现在想对 nodejs 的服务进行进程管理与监控，选用了 pandora.js。根据官网的介绍，现在出现了2个问题。
- 服务无法后台启动
- 图形化界面无法启动
具体操作步骤如下： 系统：ubuntu 16.0.4
# index.js 文件
const Koa = require('koa');
const app = new Koa();
app.use(async ctx => {
ctx.body = 'Hello World';
});
app.listen(3000);
node -v
cnpm i pandora -g
pandora init ./index.js
# 服务前台运行
pandora start -d
npm i pandora-dashboard -g
pandora start --name dashboard `pandora-dashboard-dir`
[Pandora.js] Switch current working dir to /home/james/.nvm/versions/node/v10.16.0/lib/node_modules/pandora-dashboard

你这问题描述文不对题啊：
- 上面那个不是 Koa 代码么？不是 Egg
- 看报错信息是 pandora 自己的 CLI 报错，都还没到框架那层。
Egg 进程管理自带了，监控和分析除了 AliNode 没有一个能打的。 PM2 这种只能单机看看几个小数据，跟 AliNode 根本不是一个层面的概念。
- 好的，EGG代码量较多，不好上传，所以写了koa的代码
- alinode可以做资源监控，如果一台机器上部署了多个egg项目，egg的进程管理要如何实现呢，
- 所以问题很清晰，并不是 pandora + egg 启动不了 ，而是 pandora 自身有问题，可能是什么插件或依赖没装好吧。
- docker 化。 就算你没 docker 化，进程管理没什么需要搞的啊，egg 本身就帮你搞定了进程守护，你无非就需要 npm start 和 npm stop 来启动和关闭就够了。
