打包文件

[root@localhost opt]# yum -y install maven
[root@localhost opt]# cd tomcat-java-demo/
[root@localhost tomcat-java-demo]# mvn clean package

将包文件传送过去

[root@localhost tomcat-java-demo]# scp target/myapp.war root@192.168.101.120:/usr/local/tomcat/webapps

查看打的包

[root@localhost tomcat-java-demo]# cd /root/.jenkins/workspace/
[root@localhost workspace]# ls

在tomcat主机上创建备份

[root@localhost webapps]# mkdir /opt/backup

配置流水线脚本

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git 'https://gitee.com/forgotten/tomcat-java-demo.git'

                // Run Maven on a Unix agent.
                sh "mvn -Dmaven.test.failure.ignore=true clean package"
                sh "mv target/ly-simple-tomcat-0.0.1-SNAPSHOT.war target/myapp.war"
                

                // To run Maven on a Windows agent, use
                // bat "mvn -Dmaven.test.failure.ignore=true clean package"
            }
        }
        stage('publish') {
            steps {
                //备份
                sh "ssh root@192.168.101.120 'tar -Jcf /opt/backup/myapp-$(data +%Y%m%d).tar.xz  /usr/local/tomcat/webapps/myapp'"
                sh "scp target/myapp.war root@192.168.101.120:/usr/local/tomcat/webapps"
                sh "/usr/local/tomcat/bin/configtest.sh stop;sleep 3"
                sh "/usr/local/tomcat/bin/configtest.sh start"
                
            }
        }
    }
}
