Joyent no.de 试用和配置笔记

配置

1) 提交一个 ssh pub key。

2) windows 中可能没有 ssh config 文件,先要在 %home%.ssh 下新建 config 文件,内容写入:

Host ambar.no.de
  Port 18360
  User node
  ForwardAgent yes

3) 命令行 ssh 登入,这里用的是我喜欢的 powershell :

PS C:\Users\lj> ssh ambar.no.de
Last login: Sat Dec 17 03:41:31 2011 from 10.2.136.43

                 /____/  Welcome to ambar.no.de

Useful Commands:
 pkgin -h
 node-service-info
 node-service-log
 node-service-restart
 node-service-disable
 node-service-enable
 node-service-howto

no.de 的 SmartMachine 比 heroku 好用就在这里,让你感觉你有一个真正的机器,不用麻烦地去记忆 heroku 的命令。

先看看运行的 nodejs 版本:

[node@ambar ~]$ node
process.versions
{ node: '0.4.11',
  v8: '3.1.8.26',
  ares: '1.7.4',
  ev: '4.4',
  openssl: '0.9.8k' }

从 node-service-info 命令可以看到默认运行服务器位置和参数:
> /opt/nodejs/v0.4/bin/node /opt/nodejs/default_server/server.js

通过 pkgin 可以很方便地安装软件:

4) 新建本地 repo , 新建 app.js,push 测试代码:

git push ambar.no.de master

remote: error: Cannot deploy without either a 'package.json' or 'server.js'.
remote: See <http://wiki.joyent.com/display/node/Node+Home> for more info.
remote:

remote: Starting node-service.
remote: Rollback succeeded.
To ambar.no.de:repo
 * [new branch]      master -> master

出错了! 默认服务器引导的文件必须名叫 server.js ,否则用 package.json 文件进行配置:
> http://wiki.joyent.com/display/node/Getting+Started+with+a+Node.js+SmartMachine

要紧的是 package.json 必须符合标准格式:

要动手写一个的,参考 express 的最直接:

https://github.com/visionmedia/express/blob/master/package.json

package.json 样例:

{
"name"       : "ambar.no.de",
"version"    : "0.0.1",
"description": "have fun with no.de",
"scripts"    : { "start": "node ./app" }
}

或者更酷一点,可以在 ssh 中用 npm 安装 CoffeeScript:


// npm install -g coffee-script
// 用 coffee 引导应用:
{ "start": "coffee ./app" }


http = require 'http'
port = process.env.PORT || 80

http.createServer (req,res) -> 
  res.writeHead 200, {'Content-Type': 'text/plain'}
  res.end 'Hello World\n'
.listen port

console.log "Listening on port " + port

再 push 一遍,应用就成功运行了。

如何设置 node 版本:
> http://wiki.joyent.com/display/node/Setting+the+Node.js+Version

简易的方式是新建一个 config.json 文件,内容如下:

{ "version": "latest" }

查看所有可用的 nodejs 版本:

cat /opt/nodejs/NODE-BUILDS
