IoTTalk system by liny@cs.nctu.edu.tw ( 林一平 )

 cd
 wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
 tar xzvf Python-3.6.5.tgz
# Build Python3
 cd Python-3.6.5
 ./configure --prefix=/usr/local
 make -j 2  
 sudo make install 
 sudo pip3 install --upgrade pip

(5b)補充說明
# ///pip is already installed if you are using Python 2 >=2.7.9  .. 
# /// ..  or Python 3 >=3.4 downloaded from python.org or //
# /// or  if you are working in a Virtual Environment created by virtualenv or pyvenv.
# // If you have no PIP, do:
# // curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
# // python get-pip.py
# // Reference: https://pip.pypa.io/en/stable/installing/

(二) IoTTalk Server 部分： 
(6) Obtain iotTalk
# Grab the iottalk_server_1.0   using git clone
 cd
 # git clone https://IoTtalk_Share:iottalkshare2016@bitbucket.org/IoTtalk/iottalk_server_1.0.git
 # sorry the above github NO Longer exist now
# # Now require Authorization; You need a GitLab account, and ..
# # Please contact "林勻蔚博士"<jyneda@gmail.com>

 git clone https://gitlab.com/IoTtalk/iottalk-v1.git iottalk_server_1.0
或 把帳號密碼寫進去命令列 (用 script 就需要這樣):
 git clone https://gitlab帳號:gitlab密碼@gitlab.com/IoTtalk/iottalk-v1.git iottalk_server_1.0

 cd iottalk_server_1.0       
 sudo pip3 install -r requirements.txt


(7) Mail utility, and  you may also need uwsgi, nginx
  (7a) Mail utility  --   (Cyber device: Message的功能需要) 
     # for Ubuntu/Debian/LinuxMint:
       sudo apt-get install mailutils -y

  (7b) nginx   ( as reverse Proxy ; 搭配 uwsgi 跑 CSM 和 CCM ) 
      sudo -H apt-get install nginx -y

  (7c) uwsgi   (should be done after Python3 installed)
      sudo -H apt install libpcre3 libpcre3-dev -y
      sudo -H pip3 install uwsgi

  (7d)如果選用 uwsgi 執行 CSM 和 CCM,
      則在 lib/startup.sh 內必須:
        d1) 選用 uwsgi 執行 CSM
        d2) 選用 uwsgi 執行 CCM
        d3) 不要執行 web.py
        d4) 要正確設定 nginx 讓 http 正確轉接 (d1) 和 (d2)  
  (7e)可以 點這看 nginx 設定檔範例 http://iottalk.vip/wsgi_nginx_conf/
      (其中 iottalkuser 要換成你執行 IoTTalk server 的帳號名稱,
       這檔案 和 以下兩檔案有關: (裡面 uid = iottalk  要改為  uid = 你IoTtalk帳號)
          lib/wsgi_csm.ini      for CSM
          lib/ccm/wsgi_ccm.ini  for CCM 
  (7f)如果你使用 source iotubu 做快速自動部署 IoTTalk server,
       則以上 iotubu 會自動幫忙完成 ! 
       你可以用 wget http://iottalk.vip/iotubu 取得這檔案; 
      或:
        點這看 iottalk.vip/iotubu 檔案

 
(8) test to see if it works?
  sudo -u iottalk /home/iottalk/iottalk_server_1.0/setup/startup.sh

 # then, ..
 # use browser to test your site
 # for example:
   http://iottalk.vip
 

(9) Make it run automatically
  modify /etc/rc.local

 #add the following line   (Note that we assume the account is iotsvr)
 sudo -u iotsvr  /home/iotsvr/iottalk_server_1.0/setup/startup.sh


(10) Reboot the system
 Then, reboot your system to let IoTTalk Server RUN  automatically using the account iotsvr

  sudo reboot 



(三) How to check if IoTTalk Server is running OK ?  
    Make sure you are login as iotsvr  (你執行 IotTalk server 的帳號)
    screen -r
    then use Ctrl+ RIGHT_KEY to switch to next screen window
    use Ctrl+A d   to detach the screen console

   重開機後，下指令 screen -ls，先看有沒有看到screen 在跑，
   然後再下指令 screen -r，去看裡面有沒有五個分頁 
      (按 ctrl + 方向鍵會切換分頁)，若以上都有看到，
         且分頁內最後一行不是錯誤訊息，則表示安裝成功。
     敲 CTRL_A 然後敲 d 讓 screen 回到背後跑。
  * 萬一不小心打了 screen 沒帶參數 -r  會啟動另一支 screen 此時沒分頁, 可敲 CTRL_d 結束此新 screen !!
  * 萬一不小心打了 screen 沒帶參數 -r  然後又敲了 CTRL_A + d 把它踢到後面, 此時再打 screen -r 會說有多個 screen, 
    此時可以照畫面指示先把沒用的 screen 叫回來並敲 CTRL_D 結束它。
