# 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
|
||
|
||
## 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
|
||
```
|
||
|
||
## 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/
|
||
$ 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 -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 install imagemagick
|
||
$ convert -version # 檢查是否安裝成功，並確認版本
|
||
```
|
||
|
||
## 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
|
||
$ 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
|
||
$ 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 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.
|
||
```
|
||
|
||
## 設定備份（以備份一週內容為例）
|
||
### 一、資料庫備份
|
||
```sh
|
||
$ 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
|
||
```
|
||
|
||
```txt
|
||
# 附註 logrotate
|
||
/home/rulingcom/*/*/log/*.log {
|
||
daily
|
||
rotate 7
|
||
compress
|
||
missingok
|
||
notifempty
|
||
create 644 rulingcom rulingcom
|
||
postrotate
|
||
[ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid`
|
||
endscript
|
||
}
|
||
|
||
/home/rulingcom/*/*/*/log/*.log {
|
||
daily
|
||
rotate 7
|
||
compress
|
||
missingok
|
||
notifempty
|
||
create 644 rulingcom rulingcom
|
||
postrotate
|
||
[ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid`
|
||
endscript
|
||
}
|
||
|
||
|
||
/var/log/mongodb/*.log {
|
||
daily
|
||
rotate 7
|
||
compress
|
||
missingok
|
||
notifempty
|
||
create 644 rulingcom rulingcom
|
||
postrotate
|
||
[ ! -f /var/lib/mongodb/mongod.lock ] || kill -SIGUSR1 `cat /var/lib/mongodb/mongod.lock`
|
||
endscript
|
||
}
|
