Jenkins流水线项目发布

CI/CD代码发布流程

 

 本次环境为：

主机名	IP	已安装的服务
localhost	192.168.44.128	tomcat jenkins
node1	192.168.44.129	tomcat

 

//准备工作
[root@localhost ~]# systemctl disable --now firewalld
[root@localhost ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
[root@localhost ~]# setenforce 0
[root@localhost ~]# yum -y install maven git
[root@localhost ~]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.44.129 node1
[root@localhost ~]# ssh-keygen -t rsa  //全部按回车
[root@localhost ~]# ssh-copy-id root@192.168.44.129

[root@node1 ~]# systemctl disable --now firewalld
[root@node1 ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
[root@node1 ~]# setenforce 0

首先把源替换成国内源

再安装Pipeline、Publish Over SSH、Publish Over SSH、SSH Build Agents、Git、GitHub、GitLab、Gitee插件（如果出现错误多装几次）

 

新建任务

pipeline {
    agent any
    
    stages {
        stage('pull code') {
            steps {   #拉取代码
                git 'http://github.com/lizhenliang/tomcat-java-demo.git'
            }
        }

        stage('package') {
            steps {        #打包代码
                sh """    
                mvn clean
                mvn package
                """
            }
        }
         stage('deploy') {
            steps {        #scp命令传输包到部署机上并重启tomcat环境
                sh """
                scp target/ly-simple-tomcat-0.0.1-SNAPSHOT.war root@192.168.44.129:/usr/local/apache-tomcat-9.0.46/webapps
                ssh root@192.168.44.129 "bash /usr/local/apache-tomcat-9.0.46/bin/shutdown.sh && bash /usr/local/apache-tomcat-9.0.46/bin/startup.sh"
                """
            }
        }
    }
}

 

 

 

 

基于参数构建流水线流程

pipeline {
    agent any
    
    stages {
        stage('pull code') {
            steps {
                git "${GIT_URL}"    #调用仓库地址变量
            }
        }
 stage('package') {
            steps {        
                sh """    
                mvn clean
                mvn package
                """
            }
        }
         stage('deploy') {
            steps {        
                sh """    #调用maven包名，部署主机，tomcat安装目录
                scp target/${MAVEN_PACK}.war root@${DEPLOY_HOST}:${TOMCAT_DIR}webapps
                ssh root@192.168.44.129 "bash ${TOMCAT_DIR}bin/shutdown.sh && bash ${TOMCAT_DIR}bin/startup.sh"   #远程命令控制部署机重启tomcat服务
                """
            }
        }
    }
}
