基于ssh key 拉取代码

实现jenkins服务器到gitlab服务器的基于密钥的验证,可以让jenkins连接到gitlab执行操作

在jenkins服务上生成 ssh key
#在jenkins服务器上生成密钥对
[root@jenkins-ubunutu1804 ~]#ssh-keygen
[root@jenkins-ubunutu1804 ~]#cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC/LAA5tcFrSLye3QE9a+RH8LSYzwewJ4MBSBvVP7pImKMqg21WozWw56RKqiSsj9ewO8zL43yfAwOjetrKr2Ovbxw9bOaxj0r1CobpXsD5H7pS4Cq0lLJxSmFwCLroz1C9ecGhBWBmaCbkOaJ0Q6JLTO830w7noTFYZq4/NWTGtE4xpVDDNUFTAS4j4T/0QQF6YvXIqw0EzdKKkuZLw9Rl9f2j7D1eNJX3QyY2LSgxPsXE77PzlKeJue0FKa0JwzNeKNS01rM9ztoc0VQVhxjOgjY+rhoUtBFYwxXQLmwtBq82dh6qVBKrCDpNIPE+XaXFZVMyZ0Ahs3vD2iIP9Xz/ root@jenkins-ubunutu1804
在gitlab服务器上添加上面生成的ssh key

jenkins配置自动构建部署插图(1)

在jenkins服务器上测试 ssh key

测试可以不使用用户名密码后直接获取代码

先在gitlab查看项目的下载地址:code>git@10.0.0.100:testgroup/testproject.git

在jenkins服务器上执行克隆,不再需要用户和密码

[root@jenkins-ubunutu1804 ~]#git clone git@10.0.0.100:testgroup/testproject.git

配置jenkins到gitlab非交互式拉取代码

jenkins 服务器添加凭据

将代码部署至后端服务器

先和后端服务器实现基于key验证

[root@jenkins-ubunutu1804 ~]#ssh-copy-id 10.0.0.102
[root@jenkins-ubunutu1804 ~]#ssh 10.0.0.102
Last login: Sat Mar  7 18:46:25 2020 from 10.0.0.1
[root@web-ubuntu1804 ~]#exit
logout

-rw-r--r-- 1 root root   17 Mar  7 18:58 README.md

访问后端服务器页面验证是否成功

范例:针对tomcat后端服输,构建执行shell脚本内容

ssh-copy-id tomcat服务器IP #实现到生产服务器的免密钥认证
cd /var/lib/jenkins/workspace/linux36-job1/ 
tar czvf code.tar.gz index.html 
scp code.tar.gz www@192.168.7.105:/data/tomcat/tomcat_appdir/
scp code.tar.gz www@192.168.7.106:/data/tomcat/tomcat_appdir/
ssh www@192.168.7.105 "/etc/init.d/tomcat stop && rm -rf /data/tomcat/tomcat_webdir/myapp/* && cd /data/tomcat/tomcat_appdir && tar xvf code.tar.gz -C /data/tomcat/tomcat_webdir/myapp/"
ssh www@192.168.7.106 "/etc/init.d/tomcat stop && rm -rf /data/tomcat/tomcat_webdir/myapp/* && cd /data/tomcat/tomcat_appdir && tar xvf code.tar.gz -C /data/tomcat/tomcat_webdir/myapp/"
ssh www@192.168.7.105 "/etc/init.d/tomcat start"
ssh www@192.168.7.106 "/etc/init.d/tomcat start"
更新代码再次构建,查看后端服务器是否能自动更新
