# Ubuntu 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 ## 修復舊的 logrotate 的bug ```sh $ curl http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/fix_logrotate.sh | sh ``` ## 建立 rulingcom 帳號(若已是 rulingcom 帳號,前往下一步驟) ```sh $ sudo su # 從當前帳號切換到 root $ adduser rulingcom $ # set the password for rulingcom $ # fill in user information, it's ok to leave all blank $ usermod -aG sudo rulingcom # 讓 rulingcom 可用 sudo $ su - rulingcom $ sudo ls -la /root # 測試 rulingcom sudo 是否可用 $ exit; exit # 第一次 exit 退回 root 帳號,第二次 exit 退回剛登入的帳號 ``` ## 下載裝機script並執行(除了網站的部分需手動,其餘皆已改為自動,其他內容不用再執行) ```sh $ wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/install_orbit_environment.sh -O install_orbit_environment.sh $ source install_orbit_environment.sh #請使用要執行網站的user(須為具有sudo權限之帳號)來執行,執行後會需要輸入user密碼 ## 以下其他內容均不需執行,可直接進行架站或移機 ``` ## 安裝libgmp(Ubuntu 14.04需要) ```sh sudo apt install libgmp-dev ##此套件為nokogiri相依套件 ``` ## 安裝 Nginx 1.14 ```sh $ sudo apt update $ sudo apt install nginx $ nginx -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 nginx.conf # add `include /etc/nginx/orbit_sites/*;` to Virtual Host Configs block $ 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 http://archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb #Ubuntu 20.04LTS $ sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu5.6_amd64.deb #Ubuntu 20.04LTS $ 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 ImageMagick 6.9.7-4 (部份預設模組需要處理圖片,此為相依軟體) ```sh $ sudo apt-get install libjpeg62 $ wget http://download.sourceforge.net/libpng/libpng-1.5.13.tar.gz $ tar xvfz libpng-1.5.13.tar.gz $ cd libpng-1.5.13/ $ ./configure $ make $ sudo make install # 編譯jpeg套件 $ sudo apt install -y libltdl-dev graphviz libpng-dev libfftw3-dev $ sudo apt-get install -y libjpeg-turbo8-dev $ sudo apt install -y libgif-dev libjpeg-dev libopenexr-dev libpng-dev libwebp-dev $ sudo apt install -y cmake pkg-config libbrotli-dev # Build imagemagick $ wget http://www.imagemagick.org/download/ImageMagick.tar.gz $ tar xvfz ImageMagick.tar.gz $ cd ImageMagick-7.1.0-16/ # cd ImageMagick-x.x.x-x(版本號) $ ./configure --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes --disable-shared --with-modules ##在configure跑完後,可確認Delegates是否有jpeg png zlib(最後一行) $ make $ sudo make install $ sudo ln -s /usr/local/lib/* /usr/lib/. $ sudo ln -s /usr/local/lib/pkgconfig/* /usr/lib/pkgconfig/. $ sudo ln -s /usr/local/bin/* /usr/bin/. $ convert -list configure #確認為版本7.1.0.0以上 ####以下為舊的imagemagick安裝方式(請不要使用,會有圖片上傳後,解碼失敗問題) #$ sudo apt install imagemagick #$ convert -version # 檢查是否安裝成功,並確認版本 #$ identify -version #檢查Delegates是否有jpeg png zlib ``` ## Ubuntu 20.04 才需要的步驟 ```sh ###安裝 libssl1.0-dev $ sudo sh -c "echo 'deb http://security.ubuntu.com/ubuntu bionic-security main' >> /etc/apt/sources.list" $ sudo apt update && apt-cache policy libssl1.0-dev $ sudo apt-get install libssl1.0-dev ``` ## 設定host IP(避免VM抓不到domain對應的IP) ```sh # sudo vim /etc/hosts 加入以下內容 59.120.142.210 gitlab.tp.rulingcom.com 59.120.142.206 ruling.digital store.tp.rulingcom.com 151.101.1.227 index.rubygems.org rubygems.org 104.192.141.1 bitbucket.org ``` ## 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/rulingcom/.rvm/scripts/rvm $ sudo vi /etc/apt/sources.list # Ubuntu 20.04LTS add `deb http://security.ubuntu.com/ubuntu bionic-security main` $ rvm install 2.1.2 $ rvm install 2.1.10 $ rvm --default use 2.1.10 ``` ## 若以上安裝RVM失敗可用另一種方式安裝RVM和ruby ```sh $ sudo apt-get install software-properties-common $ sudo apt-add-repository -y ppa:rael-gc/rvm $ sudo apt-get update $ sudo apt-get install rvm $ echo 'source "/etc/profile.d/rvm.sh"' >> ~/.bashrc $ source "/etc/profile.d/rvm.sh" $ rvm install 2.1.2 $ rvm install 2.1.10 $ rvm --default use 2.1.10 ``` ## 安裝screen ```sh $ sudo apt-get install screen ``` ## 安裝 R4.5 ### 一、建立 ssh key pair ```sh $ cd /home/rulingcom/.ssh # 如果沒有該資料夾則自行建立 `mkdir /home/rulingcom/.ssh`,接著進入 .ssh 資料夾 $ 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 http://gitlab.tp.rulingcom.com/orbit_chiu1/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 $ gem install nokogiri -v 1.7.0.1 #For Ubuntu 20.04LTS $ 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. ``` ## 開啟crontab的log(獨立顯示) ### Open the file ```sh sudo vim /etc/rsyslog.d/50-default.conf ``` ### Find the line that starts with: #cron.* ```sh uncomment that line, save the file, and restart rsyslog: sudo service rsyslog restart You should now see a cron log file here: /var/log/cron.log ``` ## 設定備份(以備份一週內容為例) ### 一、資料庫備份 ```sh #### 安裝postfix,以避免NO MTA installed. sudo apt-get install -y postfix sudo service postfix start $ sudo crontab -e # 內容如下: 0 3 * * * mongodump -o /home/backup/db/`date "+\%Y\%m\%d"`_db 0 4 * * * rm -fr /home/backup/db/`date --date="1 week ago" "+\%Y\%m\%d"`_db ``` ### 二、R4.5 網站目錄備份 ```sh # 安裝 rsnapshot,如已安裝則直接編輯 /etc/rsnapshot.conf $ sudo apt-get install rsnapshot -y $ sudo vim /etc/rsnapshot.conf # 內容建附註 rsnapshot $ sudo mkdir /home/backup $ sudo mkdir /home/backup/orbit $ sudo chmod 777 /home/backup/orbit $ rsnapshot -t daily # 測試是否設定正確 $ sudo crontab -e # 加入下行內容後,儲存退出 15 4 * * * /usr/bin/rsnapshot daily ``` ```txt # 此為附註 rsnapshot # 注意!該檔使用 tab 而非 space! # find BACKUP LEVELS /INTERVALS part # at this part, remove every lines with `retain` and then add the line below: retain daily 7 # find SNAPSHOT ROOT DIRECTORY part # modify the snapshot dir path snapshot_root /home/backup/orbit # find BACKUP POINTS / SCRIPTS part # add R4.5 site backup backup /home/rulingcom localhost/ ``` ### 三、定期壓縮與刪除 log ```sh $ sudo vim /etc/logrotate.d/orbit # 內容見附註 logrotate $ sudo logrotate -d /etc/logrotate.conf # 確認系統是否有使用 /etc/logrotate.d/orbit $ sudo /usr/sbin/logrotate -f /etc/logrotate.conf #測試執行log壓縮程序,看是否能成功壓縮log ``` ```txt # 附註 logrotate /home/rulingcom/*/*/log/*.log { daily rotate 7 compress missingok notifempty copytruncate postrotate [ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid` endscript } /home/rulingcom/*/*/*/log/*.log { daily rotate 7 compress missingok notifempty copytruncate postrotate [ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid` endscript } /var/log/mongodb/*.log { daily rotate 7 compress missingok notifempty create 644 mongodb mongodb postrotate [ ! -f /var/lib/mongodb/mongod.lock ] || kill -USR1 `cat /var/lib/mongodb/mongod.lock` endscript } ``` ### 四、主機開機網站自動起始 ```sh # 開機網站自動起始 $ sudo vim /etc/init.d/orbit # 內容見附註 orbit $ sudo chmod 755 /etc/init.d/orbit $ update-rc.d orbit defaults $ sudo systemctl start orbit $ sudo systemctl enable mongod.service #ubuntu18.04以上適用(可在系統boot時,自動開啟mongo) $ sudo mv /etc/init.d/mongod /etc/systemd/system/ && sudo systemctl enable mongod.service $ sudo crontab -e #加入以下#內容 # @reboot /bin/bash -l -c "rm -f /tmp/mongodb-27017.sock && chown mongodb:mongodb /var/lib/mongodb/ -R && chown mongodb:mongodb /var/log/mongodb -R && /usr/sbin/service mongod restart && /etc/init.d/orbit restart" ``` ```txt # 附註 orbit 底下#!/bin/bash請務必要加 #!/bin/bash ### BEGIN INIT INFO # Provides: ruling.digital # Required-Start: $network # Required-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start orbit daemon at boot time # Description: Start orbit daemon at boot time ### END INIT INFO ORBIT_USER=rulingcom if [ -f "/home/$ORBIT_USER/.rvm/scripts/rvm" ]; then source /home/$ORBIT_USER/.rvm/scripts/rvm rvm use default else if [ -f "/etc/profile.d/rvm.sh" ]; then source /etc/profile.d/rvm.sh elif [ "$1" != "setup" ]; then echo "" echo "-----------------------------------------------------" echo "Orbit server dependencies is missing.
