一.Jenkins服务器配置秘钥对并上传到Gitlab中

1>.在Jenkins后端生成秘钥对

[root@jenkins ~]# ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
Generating public/private rsa key pair.
Created directory '/root/.ssh'.
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:
e1:75:1f:cf:18:02:5e:b7:16:99:14:75:56:73:ac:ad root@jenkins.yinzhengjie.org.cn
The key's randomart image is:
+--[ RSA 2048]----+
|          . ..=BB|
|         . o .o+=|
|        . o o =o |
|       . o . +.*.|
|        S     o.o|
|              E  |
|                 |
|                 |
|                 |

2>.查看服务端的公钥和私钥

[root@jenkins ~]# cat /root/.ssh/id_rsa.pub 　　　　　　　　　　　　#查看公钥

[root@jenkins ~]#

3>.将Jenkins服务器端的公钥上传到GitLab中

二.Jenkins关联GitLab的WebUI界面配置

1>.创建新任务

2>.编辑任务名称

3>.源码管理选择git，并将git的地址填写为GitLab的地址

4>.将Jenkins服务器端的私钥上传到Jenkins的webUI中

5>.关联GitLab

三.小试牛刀-使用Jenkins执行shell命令

1>.在Jenkins服务端创建测试目录

[root@jenkins ~]# mkdir  -p /home/yinzhengjie/data/jenkins/www 
[root@jenkins ~]# 
[root@jenkins ~]# chown -R jenkins.jenkins /home/yinzhengjie/data/jenkins/www/
[root@jenkins ~]# 
[root@jenkins ~]# ll -d /home/yinzhengjie/data/jenkins/www/
drwxr-xr-x 2 jenkins jenkins 6 Sep  9 08:04 /home/yinzhengjie/data/jenkins/www/
[root@jenkins ~]# 
[root@jenkins ~]# chmod +x /home/yinzhengjie/ -R    　　　　　　　　　　　　#这个执行权限必须得加，因为Jenkins默认是没有访问yinzhengjie用户家目录的权限哟！
[root@jenkins ~]# 
[root@jenkins ~]# ll  /home/yinzhengjie/data/jenkins/www/
total 0
[root@jenkins ~]#

2>.构建选择-Execute shell

3>.自定义需要执行的shell命令（温馨提示：Jenkins默认的工作目录是：/var/lib/jenkins/workspace/，如果之前没有执行任务，workspace默认是不存在的，当执行第一个Jenkins任务时自动创建）

4>.运行任务

5>.Jenkins任务执行成功后查看服务器端测试目录是否有数据

6>.成功执行任务后，我们会发现在服务器端会生成“/var/lib/jenkins/workspace/”目录

四.Jenkins执行任务的具体步骤

1>.点击项目名称

2>.查看编译的历史

3>.查看控制台输出

4>.
