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
