jenkins流水线项目发布(拉代码、打包、发布)
环境
| 系统 | ip、主机名 |
| redhat 8 | 192.168.100.137/redhat：提前安装好了jenkins |
| redhat 8 | 192.168.100.138/tomcat1：提前安装好了jenkins |
安装jenkins请参考Jenkins配置使用
替换Jenkins源为国内
https://updates.jenkins.io/update-center.json 改为 https://mirror.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
Jenkins打包的方式：
maven
ant
gradle
在使用功能之前，先安装几个插件
git
pipeline
gitee
如果安装报错，请多试几遍，多半是网络问题
创建新项目
这里的连接可以去github或者码云找，我贴一个现在用的

尝试打包代码
代码
pipeline { agent any stages { stage('pull code') { steps { git 'http://github.com/lizhenliang/tomcat-java-demo.git' } } stage('package') { steps { sh """ mvn clean mvn package """ } } } }
这里失败了好多次，因为网络的原因，请在网络环境良好的情况下做
尝试部署
给第二台机器做免密认证
//RedHat //做免密认证 [root@RedHat ~]# ssh-keygen -t rsa [root@RedHat ~]# ssh-copy-id root@192.168.100.138 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys root@192.168.100.138's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'root@192.168.100.138'" and check to make sure that only the key(s) you wanted were added.
//tomcat1 //关闭防火墙和selinux [root@RedHat tomcat]# setenforce 0 [root@RedHat tomcat]# systemctl disable --now firewalld
