# Ubuntu 安裝 R4.5 標準流程
2019-11-18 07:39:25 +00:00
## 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
2019-11-18 07:41:50 +00:00
2022-05-18 10:37:12 +00:00
## 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
```
2019-11-22 03:05:03 +00:00
## 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
```
2022-07-12 02:45:08 +00:00
## 下載裝機script並執行(除了需執行下一步驟的移機外,其他內容不用再執行)
```sh
2022-03-19 03:58:40 +00:00
$ wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/install_orbit_environment.sh -O install_orbit_environment.sh
2022-02-09 11:26:06 +00:00
$ 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
2022-07-12 02:45:08 +00:00
## 以下其他內容均不需執行,可直接進行架站或移機
```
## 轉移網站資料 - 1 (把資訊不直接放在command line上避免資訊存到log中)
2022-07-08 10:13:39 +00:00
2022-07-12 02:45:08 +00:00
```sh
$ wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/move_site_interactive.sh
$ bash -i move_site_interactive.sh
```
## 轉移網站資料 - 2 (把資訊放在command line)
```sh
2022-07-08 10:13:39 +00:00
$ wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/move_site.sh
# 請依照您的需求替換以下這行的變數成實際的值
$ bash -i move_site.sh $ip $port $user $remote_pass $domain $your_local_password
```
2021-12-02 14:11:05 +00:00
## 安裝libgmp(Ubuntu 14.04需要)
```sh
sudo apt install libgmp-dev ##此套件為nokogiri相依套件
```
2022-08-04 04:28:36 +00:00
## 安裝 Nginx 1.23.1及更新openssl(至少保持1.1.1以上)
2021-12-02 14:11:05 +00:00
2019-11-18 07:39:25 +00:00
```sh
2022-08-04 04:28:36 +00:00
$ wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/install_nginx.sh -O install_nginx.sh
$ bash install_nginx.sh
$ sudo wget http://gitlab.tp.rulingcom.com/erictyl/install_r45_on_ubuntu_1804lts_doc/-/raw/master/orbit_nginx -O /etc/nginx/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
2019-11-18 07:39:25 +00:00
```
2021-08-02 10:03:09 +00:00
## 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
```
2019-11-18 07:39:25 +00:00
## 安裝 R4.5
### 一、建立 ssh key pair
```sh
2019-11-25 08:13:26 +00:00
$ 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
2019-11-18 07:39:25 +00:00
$ 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
2020-11-26 08:02:38 +00:00
$ git clone http://gitlab.tp.rulingcom.com/orbit_chiu1/orbit4-5.git your_site_name
2019-11-18 07:39:25 +00:00
$ 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
2021-01-13 03:36:04 +00:00
$ gem install nokogiri -v 1.7.0.1 #For Ubuntu 20.04LTS
2019-11-18 07:39:25 +00:00
$ 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.
2019-11-18 07:41:50 +00:00
```
2019-11-22 03:05:03 +00:00
2020-06-30 09:12:30 +00:00
## 開啟crontab的log(獨立顯示)
2020-06-30 09:20:37 +00:00
### Open the file
2020-06-30 09:12:30 +00:00
```sh
2020-06-30 09:20:37 +00:00
sudo vim /etc/rsyslog.d/50-default.conf
2020-06-30 09:12:30 +00:00
```
2020-06-30 09:20:37 +00:00
### Find the line that starts with: #cron.*
2020-06-30 09:12:30 +00:00
```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
```
2019-11-22 03:05:03 +00:00
## 設定備份(以備份一週內容為例)
### 一、資料庫備份
```sh
2020-06-30 09:12:30 +00:00
#### 安裝postfix以避免NO MTA installed.
sudo apt-get install -y postfix
2020-06-30 09:20:37 +00:00
sudo service postfix start
2019-11-22 03:05:03 +00:00
$ sudo crontab -e
# 內容如下:
2020-08-02 05:25:12 +00:00
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
2019-11-22 03:05:03 +00:00
```
### 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
2019-11-25 08:13:26 +00:00
$ sudo crontab -e # 加入下行內容後,儲存退出
2020-08-02 05:25:12 +00:00
15 4 * * * /usr/bin/rsnapshot daily
2019-11-22 03:05:03 +00:00
```
```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
2019-11-22 03:05:03 +00:00
```
```txt
# 附註 logrotate
/home/rulingcom/*/*/log/*.log {
daily
rotate 7
compress
missingok
notifempty
copytruncate
2019-11-22 03:05:03 +00:00
postrotate
[ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid`
endscript
}
/home/rulingcom/*/*/*/log/*.log {
daily
rotate 7
compress

copytruncate
2019-11-22 03:05:03 +00:00
postrotate
[ ! -f /run/nginx.pid ] || kill -USR1 `cat /run/nginx.pid`
endscript
}
/var/log/mongodb/*.log {
daily
rotate 7
compress
missingok
notifempty
2022-05-18 10:14:39 +00:00
create 644 mongodb mongodb
2019-11-22 03:05:03 +00:00
postrotate
2022-05-18 10:14:39 +00:00
[ ! -f /var/lib/mongodb/mongod.lock ] || kill -USR1 `cat /var/lib/mongodb/mongod.lock`
2019-11-22 03:05:03 +00:00
endscript
}
2020-03-01 05:11:50 +00:00
```
2020-03-01 05:18:27 +00:00
### 四、主機開機網站自動起始
2020-03-01 05:11:50 +00:00
```sh
# 開機網站自動起始
2020-03-01 09:53:56 +00:00
$ sudo vim /etc/init.d/orbit # 內容見附註 orbit
2020-03-01 05:18:27 +00:00
$ sudo chmod 755 /etc/init.d/orbit
2020-03-01 09:53:56 +00:00
$ update-rc.d orbit defaults
$ sudo systemctl start orbit
2021-05-07 09:26:38 +00:00
$ 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"
2020-03-01 05:11:50 +00:00
```

### 五、網路設定
2021-02-24 02:06:22 +00:00

2020-03-01 10:26:56 +00:00
# 開機網站自動起始
$ sudo vim /etc/netplan/50-cloud-init.yaml # 內容見附註 50-cloud-init.yaml 18.04開始設定改這

2020-03-01 10:26:56 +00:00
#
```
```txt
# 50-cloud-init.yaml
# 本範例有兩塊網卡第一塊是DHCP第二塊是固定IP
# 其中因為子網路遮罩為255.255.255.0 ,所以是 /24
# This file is generated from information provided by the datasource. Changes
# to it will not persist across an instance reboot. To disable cloud-init's
# network configuration capabilities, write a file
