jenkins 使用pipline/Jenkinsfile发布项目

一、jenkins发布项目的各种方式原理都是差不多一样，pipline只是将普通的页面操作改成了类似代码的方式

二、具体执行步骤：

1.在运行jar的远程服务器，创建一个目录 /app/demo_pipline 用于接收jenkins服务器发过来的jar包

2.在运行jar的远程服务器的登录用户的家目录，创建一个目录 pipline,并且在该目录下，存放pre steps和post steps相关的shell 脚本：pipline_clean.sh 和 pipline_start.sh

pipline_clean.sh 如下：

#!/bin/bash
#删除旧的jar包
echo "开始执行了">ak.txt
rm -rf /app/demo_pipline/demo_mybatis*.jar
#判断就的java进程是否存在，存在则kill掉
isServerExist=`ps -ef|grep java |grep -v "grep"|  grep demo_mybatis | wc -l`
if [ "$isServerExist" = "0" ]; then
        echo "my_server not found"
#       exit;
elif [ "$isServerExist" = "1" ]; then
        pid=`ps -ef|grep java |grep -v "grep"|  grep demo_mybatis | awk '{print $2}'`
        kill $pid
fi
echo "结束啦啦">bbk.txt
sleep 1s

pipline_start.sh 如下：

#!/bin/bash
echo "开始发包">start.txt
nohup java -jar /app/demo_pipline/demo_mybatis-*-SNAPSHOT.jar &
echo "发包成功">finish.txt
sleep 1s

2.jenkins的配置：

a.先看build的功能，通过git拉取代码并且打成jar包

b.配置pre steps步骤：

c.配置post steps

最终的pipline脚本：

pipeline {
    agent any

    tools {
        // Install the Maven version configured as "M3" and add it to the path.
        maven "maven"
    }

    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git credentialsId: 'gitee_user_password', url: 'https://gitee.com/yangxioahui/demo_mybatis.git'

                // Run Maven on a Unix agent.
                sh "mvn -Dmaven.test.failure.ignore=true clean package"

                // To run Maven on a Windows agent, use
                // bat "mvn -Dmaven.test.failure.ignore=true clean package"
            }

           
        }
        stage('pre steps') {
            steps {
            sshPublisher(publishers: [sshPublisherDesc(configName: 'vagrant_10', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: 'sh pipline/pipline_clean.sh', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
            }

           
        }
        stage('post steps') {
            steps {
              sshPublisher(publishers: [sshPublisherDesc(configName: 'vagrant_10', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: 'nohup sh pipline/pipline_start.sh', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '/demo_pipline', remoteDirectorySDF: false, removePrefix: 'target/', sourceFiles: 'target/demo_mybatis-*-SNAPSHOT.jar', usePty: true)], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)]) 
            }

           
        }
    }
}

上面的pipline脚本就是Jenkinsfile

启动结果：
