Cloud Service Software

• 
  
• 選擇架設環境 與 Stack
• 1. Self-host Ubuntu 14.04 LTS with dokku
• 2. Self-host Ubuntu 14.04 LTS with Passenger + Nignx
• 3. Heroku Service
• 
  
• Self-hosted Backend Installation Detail
• 
  
• 
  
  • 
    
• Farmbot-Web-API

• https://drive.google.com/file/d/0B3xfDXAshpYmUjZlVWVLOVhRTzA/view?usp=sharing
• 
  
• Online version : https://my.farmbot.io/
• Main reference of set up Ruby on Rail Environment: https://gorails.com/setup/ubuntu/14.04
• 
  
• 1. Install RVM for Ruby version management ( if any update error, try  "sudo apt-get update" first )
• https://rvm.io/rvm/install
• rvm 安裝會先作 sudo apt-get update，如果有任何repository url 404找不到就會終止
• 處理方法：http://stackoverflow.com/questions/23650992/ruby-rvm-apt-get-update-error
• 
  
• 2. libpg-dev for ubuntu
• Install libpg-dev
• 
  
• 3. 安窗 bundler

•     gem install bundler
•     bundle install
• 
  
• 4. Copy config/database.example.yml to config/database.yml. 
• 
  
• 5. 先確認 postgresql 是否有安裝與正常啟動，可參考：https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-14-04
• 接下來要創一個 user帳號 (和ubunut現在一樣名字的帳號)，必須有 CREATEDB和LOGIN的 Privilege
• 
  

•     sudo apt-get update
•     sudo apt-get install postgresql postgresql-contrib
•     sudo -i -u postgres #change user to postgress account
•     psql #switch to psql prompt
•     \du #dipslay user
•     CREATE ROLE your_username WITH CREATEDB LOGIN;
•     \du #check create successfully
•     \q
• 
  
• 相關可參考：https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-14-04
• 
  
• 6. migrate Farmbot-Web-API 資料庫結構
• rake db:create:all db:migrate db:seed
• 
  
• 7. 防火牆設定，Web API 基於 Ruby on Rail  預設是用 3000 port (看你自己是用啥，我是用ufw簡單)
• 關於 Deployment
• https://github.com/ykhorzon/Farmbot-Web-API/blob/master/DEPLOYMENT.md
• 
  
• Farmbot-web-frontend

• 
  
• MQTT-Gateway
• npm install
• fatal error: zmq.h: No such file or directory, Solution: JustinTulloss/zeromq.node#281
• MQTT Port 1883

重新綁定Farmbot OS 和 登入帳號的方法

1. 將 pi 拿出wifi範圍 或 將wifi斷線，pi自動會轉回AP mode
2. 電腦遠則farmbot-XXX wifi，連入後開啟網頁瀏覽器 http://192.168.24.1/
3. 設定 pi configuration，其中就包含綁定my.farmbot.io帳號
