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_rsaGenerating 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.cnThe key's randomart image is:+--[ RSA 2048]----+| . ..=BB|| . o .o+=|| . o o =o || . o . +.*.|| S o.o|| E || || || |+-----------------+[root@jenkins ~]#
2>.查看服务端的公钥和私钥

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>.
