1、部署機代碼目錄結構html
使用www用戶進行代碼部署，全部部署機上須要建立www用戶，並賦予根目錄權限，同時配置公私鑰認證創建信任關係。node
[www@ansible-node1 deploy]$ tree . ├── code │?? └── web-demo #存放代碼 │?? ├── index.html │?? └── \351\227\256 ├── config #存放服務器配置文件 │?? └── web-demo │?? ├── base │?? │?? └── config.ini │?? └── other │?? └── 192.168.226.130.crontab.xml #不一樣機器之間的差別匹配值文件 ├── tar └── tmp
2、部署節點git
ip：192.168.226.130、192.168.226.132 分別模擬兩個主機組來部署不一樣代碼web
web根目錄: /webroot/webdemo、同時賦予www用戶權限shell
歷史代碼版本保存路徑： /opt/webroot、同時賦予www用戶權限bash
3、使用gitlab來管理代碼（在此不作介紹）服務器
4、主要做用ssh
經過腳本，模擬線上環境，實現代碼的半自動化部署，以及秒級回滾。curl
5、腳本實現 gitlab
流程：獲取代碼（直接拉取）-----> 編譯（可選）-------> 配置文件 ------>打包 -----> scp到目標服務器---->將目標機服務器移除集羣----->解壓---->放置到webroot----->scp差別文件----->重啓（可選）----->測試----->加入集羣

6、執行腳本
[www@ansible-node1 ~]$ bash deploy.sh Usage: deploy.sh {deploy | rollback [ list | version]} [www@ansible-node1 ~]$ bash deploy.sh deploy #部署代碼 [www@ansible-node1 ~]$ bash deploy.sh rollback list #列出代碼版本 -rw-rw-r-- 1 www www 228 Mar 7 17:03 /opt/webroot/web-demo_123_2018-03-07-17-03-52.tar.gz -rw-rw-r-- 1 www www 231 Mar 7 17:05 /opt/webroot/web-demo_123_2018-03-07-17-05-24.tar.gz -rw-rw-r-- 1 www www 233 Mar 7 17:07 /opt/webroot/web-demo_123_2018-03-07-17-07-02.tar.gz -rw-rw-r-- 1 www www 231 Mar 7 17:10 /opt/webroot/web-demo_123_2018-03-07-17-10-36.tar.gz -rw-rw-r-- 1 www www 234 Mar 8 16:24 /opt/webroot/web-demo_123_2018-03-08-16-24-17.tar.gz -rw-rw-r-- 1 www www 230 Mar 8 16:26 /opt/webroot/web-demo_123_2018-03-08-16-26-51.tar.gz -rw-rw-r-- 1 www www 230 Mar 8 16:30 /opt/webroot/web-demo_123_2018-03-08-16-30-15.tar.gz -rw-rw-r-- 1 www www 229 Mar 8 16:31 /opt/webroot/web-demo_123_2018-03-08-16-31-25.tar.gz [www@ansible-node1 ~]$ bash deploy.sh rollback web-demo_3d9c99_2018-03-12-16-27-54 #回滾到指定版本
