使用jenkins将项目部署到另一台主机的过程

作者:逐流·

这篇文章主要介绍了使用jenkins将项目部署到另一台主机的详细过程,这这里手动部署需要关闭防火墙,确保git命令存在,拉取部署的项目包,具体实例代码跟随小编一起看看吧

环境

 

主机名 ip地址 服务
jenkins 192.168.216.200 tomcat、jenkins
server 192.168.216.215 tomcat


//关闭防火墙selinux

//安装打包命令,git
[root@jenkins ~]#  yum -y install maven
[root@jenkins ~]#  yum -y install git

//配置免密登录
[root@localhost ~]# ssh-keygen 
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:npcyZyHpOPmqGL1nbpZRj7UYULZxJhvNIcDg2G9Qvso root@localhost.localdomain
The key's randomart image is:
+---[RSA 3072]----+
|    .oooBo+.     |
|   + oo. Xo      |
|  . + ..o        |
|     o .o..      |
|      +.S*..     |
|   o o.=oooo     |
|  . E +o* =      |
|   o .*o *       |
|  . oBo..        |
+----[SHA256]-----+
[root@localhost ~]# ssh-copy-id root@192.168.216.215
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.216.215's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@192.168.216.215'"
and check to make sure that only the key(s) you wanted were added.

[root@localhost ~]# ssh root@192.168.216.215

进入jenkins端



pipeline {
    agent any
    
    stages {
        stage('Build') {
            steps {
                // Get some code from a GitHub repository
                git 'https://gitee.com/forgotten/tomcat-java-demo.git'  #下载包,确保主机上有git命令

                // 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
                // To run Maven on a Windows agent, use
                // bat "mvn -Dmaven.test.failure.ignore=true clean package"
                
            } 
        }        
        stage("publish"){
            steps{
                sh "ssh root@192.168.216.215  'tar -Jcf /opt/backup/webapps-\$(date +%Y-%m%d).tar.xz   /usr/local/tomcat/webapps/*'"   #备份原有的项目
                sh "scp target/myapp.war root@192.168.216.215:/usr/local/tomcat/webapps/"  #传包到目标主机
                sh "ssh root@192.168.216.215 '/usr/local/tomcat/bin/catalina.sh stop;sleep 3;/usr/local/tomcat/bin/catalina.sh start'"   #  重启生成项目
            }
        }
    }
}


去目标主机验证

手动部署

//关闭防火墙,selinux

//确保git命令存在,拉取部署的项目包
[root@jenkins opt]# git clone https://gitee.com/forgotten/tomcat-java-demo.git
正克隆到 'tomcat-java-demo'...

[root@jenkins opt]# ls
tomcat-java-demo

// 打包,确保mvn命令存在
[root@jenkins opt]# cd tomcat-java-demo/
[root@jenkins tomcat-java-demo]# ls
db           Dockerfile   LICENSE  README.md
deploy.yaml  jenkinsfile  pom.xml  src      // 只要是带pom.xml这样文件的都是用mvn打包


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

// 确保有免密登录,通过ssh启动server端tomcat,然后把要部署的包传过去
[root@jenkins tomcat-java-demo]# scp target/myapp.war root@192.168.47.163:/usr/local/tomcat/webapps/
//tomcat会自动解压,过一会进入网站对应目录就能看到新部署的项目
