通过jenkins发布java项目到目标主机上的详细步骤

#两台主机做免密登录
[root@localhost ~]# 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:
SHA256:0zPiM+3ypvmYPisJbeL8LhA2QapiAVqwF9C+gyASonU root@localhost.localdomain
The key's randomart image is:
+---[RSA 3072]----+

ECDSA key fingerprint is SHA256:WbxvLgdwExwRlMT4gaAC1bVyIovZnAwwX1DX8dv6Rs0.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
