通过tomcat使用jenkins将项目部署到另一台主机

部署环境

安装打包的命令

[root@jenkins ~]#  yum -y install maven

设置免密登录

[root@localhost ]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:VqqALy83NiBX9LeAywKQfVWsdZO18Pnpxj4jd1sqpzE root@RS1
The key's randomart image is:

Now try logging into the machine, with:   "ssh 'root@192.168.153.156'"
and check to make sure that only the key(s) you wanted were added.

创建项目

修改脚本

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

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