Jenkins添加从节点

前提环境：

• Jenkins需要安装以下两个插件
  SSH Build Agents、Credentials
• 从节点需要安装java环境 (sudo yum install -y java-11-openjdk java-11-openjdk-devel)

ssh方式启动代理的话，有两种方式进行连接

1. 账号密码方式进行连接
2. 使用密钥方式进行连接

添加ssh连接凭证

选择以下两种方式的其中一种即可

1. 账号密码方式进行连接
   
   
   

2. 使用密钥方式进行连接

在Jenkins主机且使用启动Jenkins的用户生成

$ ssh-keygen 
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ops/.ssh/id_rsa): 
Created directory '/home/ops/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/ops/.ssh/id_rsa.
Your public key has been saved in /home/ops/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:NQNYoBjA4Psr7i/rdaWBBAmW5INwlg1I3RvGejOAUfU ops@jenkins.ecloud.com
The key's randomart image is:
+---[RSA 2048]----+
|@O%=+..+o        |
|BBo=.*o  .       |
|.+..= oE  +      |

$ ssh-copy-id -i .ssh/id_rsa ops@192.168.32.163
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: ".ssh/id_rsa.pub"

Are you sure you want to continue connecting (yes/no)? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
ops@192.168.32.163's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'ops@192.168.32.163'"
and check to make sure that only the key(s) you wanted were added.

注意：需要用Jenkins启动用户来创建密钥文件及分发文件
