本文讲述了在VMware上安装CentOS7环境中，配置Jenkins并添加SSH节点时遇到的问题，包括ssh-keygen设置、known_hosts文件管理和Java路径确认。详细介绍了如何解决SSH连接验证失败及Java版本检测不成功的问题。

前提：
1、本案例是在VMware安装CentOS7的环境完成的
2、CentOS7已配置java环境
3、CentOS7安装tomcat下启动的jenkins

Jenkins配置节点

ssh-keygen配置证书，三次回车

[root@bogon ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
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:dOVo3O2Iz9RQ4c/nTdgIjrwznDAUU2S6q/kCS6n8tPs root@bogon
The key's randomart image is:
+---[RSA 2048]----+
|        oo+ . o. |
|         * = +   |
|        + = = o  |
|       o = + * * |
|     .  S + + = *|
|    +    = *   oo|
| . o.o  . * o   o|
|  o....o   o     |
|   .+oEo.        |
+----[SHA256]-----+

ssh连接slave机ip，自动生成known_hosts文件

# 连接slave机ip
[root@bogon ~]# ssh 192.168.111.129
