一、用Jenkins发布一个项目

创建项目




点击完应用之后点击save保存，项目就创建完成了

创建完项目之后点击构建就会显示效果


绿色代表成功，点击log可以查看日志

查看输出

下面还有个流水线步骤，告诉你一步一步的该做什么

点击回放，可以查看脚本的语法

二、用命令拉取java项目

手动部署

Jenkins发布项目
克隆项目地址

tomcat部署博客

[root@manage ~]#  yum -y install git maven
[root@manage ~]# cd /opt/

// 克隆项目
[root@manage opt]# git clone https://gitee.com/forgotten/tomcat-java-demo.git

// 打包成war包
[root@manage tomcat-java-demo]# cd tomcat-java-demo/
[root@manage tomcat-java-demo]# mvn package -Dmaven.test.skip=true
[root@manage tomcat-java-demo]# ls

[root@manage tomcat-java-demo]# cd target/
[root@manage target]# ls

maven-status

// 包名过长，修改名字
[root@manage target]# mv ly-simple-tomcat-0.0.1-SNAPSHOT.war myapp.war
[root@manage target]# ls

// 备份文件
[root@manage target]# cp -r /usr/local/tomcat/webapps/ /opt/
[root@manage target]# ls /opt/
tomcat-java-demo  webapps


// 做免密登录
[root@manage target]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.

访问myapp页面

项目部署成功

自动部署

1、公有仓库部署

点击demo

点击配置


下载包位置

流水线脚本配置

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git "https://gitee.com/jinchenghe92/tomcat-java-demo.git"  // 下载包的位置

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

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


        }
        stage('publish'){
            steps{
                //sh "root@192.168.91.135 'tar Jcf /opt/backup/myapp-\$(date +%Y%m%d).tar.xz /usr/local/tomcat/webapps/myapp'"                // 备份数据
                sh "scp target/myapp.war root@192.168.91.135:/usr/local/tomcat/webapps/" // 传输包
                sh "ssh root@192.168.91.135 '/usr/local/tomcat/bin/catalina.sh stop;sleep 3;/usr/local/tomcat/bin/catalina.sh start'"      // 重启服务
            }
        }
        
        
    }
}

然后点击应用之后保存

进行构建，绿色就是访问成功了

2、私有仓库部署

gitee使用介绍

点击管理进入配置设置私有仓库

流水线脚本配置

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git credentialsId: '3096bfc5-8973-45b8-8070-7db925c5b544', url: 'https://gitee.com/amxnh/tomcat-java-demo.git'   //生成的私有仓库用户名和密码，用的私有仓库就加这个

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

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


        }
        stage('publish'){
            steps{
                //sh "root@192.168.91.135 'tar Jcf /opt/backup/myapp-\$(date +%Y%m%d).tar.xz /usr/local/tomcat/webapps/myapp'"                // 备份数据
                sh "scp target/myapp.war root@192.168.91.135:/usr/local/tomcat/webapps/" // 传输包
                sh "ssh root@192.168.91.135 '/usr/local/tomcat/bin/catalina.sh stop;sleep 3;/usr/local/tomcat/bin/catalina.sh start'"      // 重启服务
            }
        }
        
        
    }
}

私有仓库拉取代码

将生成的用户名和密码脚本带入到流水线脚本中即可

最后进行构建，绿色就是成功了
