在windows上面基于virtualbox安装flynn

为什么要flynn，它比deis heroku还牛逼，未来估计要火。当然，你学deis，heroku都可以，选择就是赌博，我就赌为了flynn。就跟赌kong reactjs一样。

安装

手工安装真他妈要死人，网络太慢。挂机在ubuntu上面安装了16个小时，没错，我就一直等到晚上2点才安装完。还是用vagrant安装吧，舒服。
```
git clone https://github.com/flynn/flynn
cd flynn/demo
```
1. 下载文件：
  
  https://dl.flynn.io/vagrant/flynn-base.json
  
  https://dl.flynn.io/vagrant/boxes/flynn-base_v20161017.1_virtualbox.box
2. 修改vagrant.file
config.vm.box_url = "https://dl.flynn.io/vagrant/flynn-base.json"

修改成

config.vm.box_url = "https://127.0.0.1:82/leapar/vagrant/flynn-base.json"
1. 修改flynn-base.json
url: "https://dl.flynn.io/vagrant/boxes/flynn-base_v20161017.1_virtualbox.box"

改成

url: "https://127.0.0.1:82/leapar/vagrant/boxes/flynn-base_v20161017.1_virtualbox.box"
1. 执行vagrant up
2. 等待
```
==> default: Flynn bootstrapping complete. Install the Flynn CLI (see https://flynn.io/docs/cli for instructions) and paste the line below into a terminal window:
==> default:
==> default: flynn cluster add -p Bm0TzBPk9dOGab46EOzlrsBXzN1dDCBTf3CJKInAAHY= default demo.localflynn.com 9c7c346247b41d8f3612e8ef65039eca
==> default:
==> default: The built-in dashboard can be accessed at http://dashboard.demo.localflynn.com and your login token is 85ba50b483faca5b1326cc20c3e3cf5b
```
1. 配置
用ssh进入127.0.0.1:2222 如果没错应该ifconfig是192.2.0.200.然后修改windows的hosts
```
192.0.2.200         localflynn.com
192.0.2.200         example.com
```
打开https://dashboard.demo.localflynn.com ，然后安装根发行证书，输入上面的token，就看见你期待的界面了。
1. ps
flynn install 会打开网页，也可以界面话安装，但是我没有成功。
维护

vagrant suspend vagrant resume

发布在dashboard里面关联了我的github账号，但是点luanche安装一直失败。所有我采用手工安装：在https://github.com/flynn-examples/ 下面有好多example，我安装了nodejs、php、go、以及static的，java的没有安装。下面开始举例：

  $git clone https://github.com/flynn-examples/go-flynn-example

  $cd go-flynn-example
  $flynn create example
  Created example

  $ git remote -v
  flynn   https://git.demo.localflynn.com/example.git (push)
  flynn   https://git.demo.localflynn.com/example.git (fetch)
  origin  https://github.com/flynn/nodejs-flynn-example.git (fetch)
  origin  https://github.com/flynn/nodejs-flynn-example.git (push)

这个可以不要，最后到dashboard上面去追加也可以。main.go里面使用了postgre，另外几个example是没使用的。flynn自带了redis、mysql、postgres、mongodb，你自己也可以使用外部数据库，在flynn env中修改。

$ flynn resource add postgres
Created resource 320f38ba-36bc-40ce-97e5-dad1b5c3bd20 and release c7b793ca-b7b1-4da0-bd1d-4ed95c1b52e8.

如果上面你追加了数据库，那么下面命令会看见数据库。

$ flynn env
DATABASE_URL=postgres://84abab8e4000453fe2e1ce3f4f04392a:[email protected]:5432/7f02ee75fe57cb70fe1e5d9afc37935c

如果上面出错，再执行一遍，成功的话，可以看见内容了。

$ curl http://example.demo.localflynn.com

进阶

你可以在dashboard中为http://example.demo.localflynn.com 添加路由为example.com，当然host要修改。问题来了:

为什么我git push flynn master就会自动部署安装，包括php、apache、nodejs、go等等运行环境？

首先你要知道有npm、composer、maven、go get然后你要知道deis heroku。 flynn基于heroku的builder制作的，当git push时候，flynn/gitreceive/receiver/flynn-receive.go会监测是否完成，如果完成那么就启flynn/slugbuilder去进行部署。这就是他的核心。另外flynn scale路由等等自己去发现，其实kong的很多内容flynn已经做了很多，两者怎么结合，自己玩去吧。
