通过tomcat使用jenkins将项目部署到另一台主机

部署环境

安装打包的命令
[root@jenkins ~]#  yum -y install maven

设置免密登录
[root@jenkins ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
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:dz9rzIoQEKZxDykFoEHfsfirgvL6Z3OEN6XtrUS9TxM root@jenkins
The key's randomart image is:
