Jenkins发布java项目到另一台主机的tomcat
安装tomcat和Jenkins的步骤略，前面的文章有写到，现在直接开始 *** 作
关闭两台防火墙，查看端口，访问页面是否正常

发送端的tomcat访问正常
发送端的Jenkins访问正常
接受端的tomcat访问正常

发送端将代码拉下来并打包成.war 包

接收端查看
# 传输成功并已经自动解压 [root@server webapps]# ls ROOT docs examples host-manager jenkins jenkins.war manager myapp(自动解压的) myapp.war(war包)
接受端访问查看
/
接收端创建一个文件夹来存放备份文件(如果有文件)
[root@server ~]# mkdir /opt/backup [root@server ~]# ls /opt/backup/ [root@server ~]#
发送端进入Jenkins web界面进行 *** 作(创建项目)
写入脚本自动执行
脚本内容
pipeline {
agent any
stages {
stage('Build') {
steps {
// Get some code from a GitHub repository
git 'https://gitee.com/jinchenghe92/tomcat-java-demo.git'
// Run Maven on a Unix agent.
sh "mvn -Dmaven.test.failure.ignore=true clean package"
sh "mv target/ly-simple-tomcat-0.0.1-SNAPSHOT.war target/myapp.war"
// To run Maven on a Windows agent, use
// bat "mvn -Dmaven.test.failure.ignore=true clean package"
}
}
stage("publish"){
steps{
sh "ssh root@192.168.220.10 tar -Jcf /opt/backup/myapp-$(date +%Y%m%d).tar.xz /usr/local/tomcat/webapps/myapp"
sh "scp target/myapp.war root@192.168.220.10:/usr/local/tomcat/webapps/"
sh "ssh root@192.168.220.10 '/usr/localtomcat/bin/catalina.sh stop;sleep 3;/usr/local/tomcat/bin/catalina.sh start'"
}
}
}
}
查看接收端是否收到 myapp.war 包
[root@server ~]# cd /usr/local/tomcat/webapps/ [root@server webapps]# ls ROOT docs examples host-manager jenkins jenkins.war manager myapp(已自动解压) myapp.war(收到)
接收端 web界面访问
