jenkins 經過自動拉取Gitlab上的代碼實現自動更新NGINX

所須要用到的環境：

Gitlab：  172.20.7.70

Jenkins：  172.20.7.71

 nginx：    172.20.7.72

gitlab 和Jenkins安裝自行百度

開始實驗操做

首先經過網頁訪問nginx，nginx默認測試頁我是改了的 ，因此看到的不是它原生的

一、先在Jenkins機器上建立好ssh密鑰對

[root@node2 ~]#ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Tkn6vspyZyn5QUwyISsLNIA6zVmo06iZVMmNZf+HprI root@node2.dklwj.com
The key's randomart image is:
+---[RSA 2048]----+
|+o..*o.          |
|o o=o+..         |
|o*oo. o.o        |
|*o=o   B...      |
|o=.   . S+ .     |
|+      =o .      |
|     . o+.       |
|    ..*.+.       |
|     Eo*+.       |
+----[SHA256]-----+

二、查看公鑰文件

[root@node2 ~]#cat /root/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCvWyCl1WXHHrPHwUNgvx3BvMNhd5mbNlJz75gAtdm0ff+a6hr4eOm2ajHMONNQq7h2QdrVqi+o+OYYK7PFfLAxmKjWYlwEdz/3J1UeclTBQKAungiazYOBVGHqL6Omhm4kdljkTP0BljgApuJD1KHm0AisJ9bDJk7YTUXhrdF53ThVaPXIDkrsBi4a+D6dnWsopCXweadoLe9qHt26yPGHAzPjlCG6qL5c7oMFBdaG5sL4iMqw9fudbkZ8q3sv+CN0brTS1uM8MtfAjnaVGHVlBHjZOOLg5WcqIvE1LSONQSyElN7xvc/mYAGErOnhyGny0QE/R1WgbMFKrT5OB59z root@node2.dklwj.com

三、經過網頁打開gitlab的操做界面




四、驗證自動拉取是否成功

五、在Jenkins上配置ssh私鑰

六、新建任務，須要提早在Jenkins主機把ssh免密鑰文件複製到nginx主機上去

[root@node02 ~]#ssh-copy-id root@172.20.7.72

七、經過Jenkins構建以後再次訪問nginx頁面
