tomcat使用jenkins部署项目到对端主机

• 使用jenkins部署项目到对端主机
• • • 1. 部署环境
    • 2. jenkins部署项目(手动部署)
    • 3. jenkins部署项目(自动部署)
    • 4. 通过代码仓库部署项目（有密码）

//先下载git工具和打包工具
[root@jenkins opt]# -y install maven git

//在github上克隆一个Java项目到本机opt目录里
[root@jenkins opt]# git clone https://gitee.com/caimengzhi/tomcat-java-demo.git
[root@jenkins opt]# ls
tomcat-java-demo

//把java项目进行打包
[root@jenkins tomcat-java-demo]# mvn clean package
[root@jenkins tomcat-java-demo]# ls
jenkins  pom.xml  README.md  src  target

[root@jenkins tomcat-java-demo]# ls target/
classes            ly-simple-tomcat-0.0.1-SNAPSHOT      maven-archiver
generated-sources  ly-simple-tomcat-0.0.1-SNAPSHOT.war  maven-status
[root@jenkins tomcat-java-demo]# 


//做免密登录
[root@jenkins ~]# ssh-keygen -t rsa
[root@jenkins ~]# ssh-copy-id root@192.168.200.151

//把项目传到对端主机
[root@jenkins opt]# scp tomcat-java-demo/target/ly-simple-tomcat-0.0.1-SNAPSHOT.war root@192.168.200.151:/usr/local/tomcat/webapps/
ly-simple-tomcat-0.0.1-SNAPSHOT.war  100%   21MB 166.7MB/s   00:00    
[root@jenkins opt]# 

//在对端主机查看，发现以及解压好了
[root@localhost webapps]# ls

[root@localhost webapps]# mv ly-simple-tomcat-0.0.1-SNAPSHOT mydemo

//重启tomcat
[root@localhost webapps]# /usr/local/tomcat/bin/shutdown.sh stop
[root@localhost webapps]# /usr/local/tomcat/bin/catalina.sh start
[root@localhost webapps]# ss -antl

先创建一个项目



编写的脚本

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git "https://gitee.com/cai-aocheng/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{
                //ssh root@192.168.200.144 'tar -Jcf /opt/backup/myapp-$(date +%Y%m%d).tar.xz /usr/local/tomcat/webapps/myapp'
                sh "scp target/myapp.war root@192.168.200.144:/usr/local/tomcat/webapps/"
                sh "ssh root@192.168.200.144 '/usr/localtomcat/bin/catalina.sh stop;sleep 3;/usr/local/tomcat/bin/catalina.sh start'"
            }
        }
    }
}

添加所myapp项目名访问（没有配置数据库）
