+# Ubuntu 18.04 LTS 安裝 R4.5 標準流程
+## 前置作業
+* Ubuntu 18.04 LTS 已安裝完畢並能遠端連線進入
+* 當前帳號可以使用 sudo 指令
+## 安裝 Nginx 1.14
+```sh
+$ sudo apt update
+$ sudo apt install ngnix
+$ ngnix -v # 確認版本為 1.14
+$ sudo systemctl status nginx # 查看 nginx 是否啟動
+$ sudo systemctl restart nginx # 安全重啟 nginx，若已啟動則可跳過此步驟
+$ cd /etc/nginx/
+$ sudo mkdir orbit_sites/
+$ sudo vim orbit_sites/xxx_ooo # 建立網站 nginx 設定檔，xxx 為學校縮寫，ooo 為系所、單位縮寫。內容參考附註 nginx 設定檔
+```
+```nginx
+# 此為附註 nginx 設定檔
+# upstream xxx_sock {
+upstream orbit_sock {
+# server unix:/path/to/your/r45/tmp/unicorn.sock;
+  server unix:/home/rulingcom/orbit_sites/orbit/tmp/unicorn.sock;
+}
+
+server {
+  listen 80;
+
+# root /path/to/your/r45/public;
+  root /home/rulingcom/orbit_sites/orbit/public;
+
+# server_name your.website.address;
+  server_name localhost;
+
+  client_max_body_size 500m;
+
+  location / {
+    try_files $uri $uri/index.html $uri.html @app;
+  }
+
+  location @app {
+    proxy_redirect     off;
+    proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header   Host              $http_host;
+    proxy_connect_timeout   360;
+#   proxy_pass http://xxx_sock;
+    proxy_pass http://orbit_sock;
+  }
+}
+```
+## 安裝 MongoDB 3.2.22
+```sh
+$ # 匯入 MongoDB 公鑰到套件管理系統
+$ wget -qO - https://www.mongodb.org/static/pgp/server-3.2.asc | sudo apt-key add -
+$ 建立 list file
+$ echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
+$ sudo apt-get update # 更新套件管理系統
+$ # 下載並安裝 MongoDB 3.2.22
+$ sudo apt-get install -y mongodb-org=3.2.22 mongodb-org-server=3.2.22 mongodb-org-shell=3.2.22 mongodb-org-mongos=3.2.22 mongodb-org-tools=3.2.22
+$ mongo --version # 查看 MongoDB 版本
+$ sudo systemctl status mongod # 查看 MongoDB 是否啟動
+$ sudo systemctl restart mongod # 安全啟動 MongoDB，若已啟動則可跳過此步驟
+```
+## 安裝 RVM (Ruby 版本和套件的管理程式)
+```sh
+$ sudo apt install gnupg2
+$ gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
+$ \curl -sSL https://get.rvm.io | bash -s stable
+$ source /home/ge/.rvm/scripts/rvm
+$ rvm install 2.1.2
+$ rvm install 2.1.10
+$ rvm --default use 2.1.10
+```
+## 安裝 R4.5
+### 一、建立 ssh key pair
+```sh
+$ ssh-keygen # 設定 key pair name -> 設定密碼(不設定直接 enter) -> 確認密碼(不設定直接 enter)
+$ cat ~/.ssh/your_key.pub # 將公鑰轉交給禾綸（注意：不是私鑰）
+$ # 確認禾綸將公鑰加入 GitLab 後再接續下列指令與步驟二
+$ eval "$(ssh-agent -s)"
+$ ssh-add ~/.ssh/your_private_key
+```
+### 二、安裝 R4.5 Web App
+```sh
+$ git clone git@gitlab.tp.rulingcom.com:saurabh/orbit4-5.git your_site_name
+$ cd your_site_name
+$ vim config/mongoid.yml # 所有 orbit_4_5 換成 your_site_name, :wq 存檔離開
+$ vim Gemfile # 加井字號註解掉 gem 'sassc-rails', '~>1.3.0' 並拿掉此行 #gem 'sass-rails', '~> 4.0.2' 井字號取消註解
+$ bundle install
+$ RAILS_ENV=production bundle exec rake assets:precompile
+$ bundle exec unicorn_rails -c config/unicorn.rb -D -E production
+$ sudo service nginx restart
+$ # Login the new create site with rulingcom account and choose “Admin Area” to complete the registration of this new created site.
