环境准备
- Git: 安装部署使用略。
- Jenkins: 2.46.2版本安装部署略(修改jenkins执行用户为root,省得配置权限)
- JDK: 安装部署略。
- Maven: 安装部署略。
- 服务器免密登陆
Jenkinsfile文件编写
node {
def mvnHome
def workspace = pwd()
stage('Preparation') { // for display purposes
// Get some code from a GitHub repository
git 'http://192.168.161.118:8080/git/demo.git'
// Get the Maven tool.
// ** NOTE: This 'M3' Maven tool must be configured
// ** in the global configuration.
mvnHome = tool 'M3'
}
stage('Build') {
// Run the maven build
if (isUnix()) {
sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
} else {
bat(/"${mvnHome}inmvn" -Dmaven.test.failure.ignore clean package/)
}
}
stage('Deploy') {
sh "'/scripts/deploy.sh' ${workspace} deploy"
}
}
Jenkinsfile文件就放在你自己的Git仓库的更目录! 如图:
在Jenkins中创建Pipeline项目
如上3图,3步,jenkins的pipeline项目创建完成。
编写部署Shell脚本

PS: deploy.sh放在/scripts目录,和JenkinsFile中写的路径一致就好
运行看效果
部署成功。。。 Jenkins的Console Output也都打印成功。 浏览器访问部署的应用也一切正常。完事!
PS:本实践适合小型集群部署。(经验有限,欢迎大神指导)
