jenkins流水线项目发布

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
