安装SSH插件
Jenkins- 插件管理- 可选插件- 搜索SSH Agent
配置启用SSH Server
Jenkins- 系统管理 - 全局安全配置， 把 SSH Server 设置为启用(默认是禁用)
新增节点
第一种方式（SSH密钥连接）：
1.Jenkins主机生成SSH密钥
[root@k8s-master ~]# ssh-keygen -t rsa 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:oI7S4uwjskL1wGBt04Xq3F2huICMKSZ8jBTfwiROlNk root@971e942b7a70 The key's randomart image is: +---[RSA 3072]----+ |.=*.. o. | |o*=E.o . | |*oB+o.o . . | |=* O.o o . | |+ = * o S | | o = + . | |+ o . | |*+ | |*=. | +----[SHA256]-----+
2.发送Jenkins主机公钥至要远程主机上
[root@k8s-master ~]# ssh-copy-id 192.168.1.20
3.测试Jenkins主机免密连接远程主机
[root@k8s-master ~]# ssh root@192.168.1.20 Last login: Fri Mar 4 10:44:53 2022 from k8s-master [root@k8s-node2 ~]#
4.添加Jenkins主机SSH私钥key为凭据
[root@k8s-master ~]# cat /root/.ssh/id_rsa -----BEGIN RSA PRIVATE KEY----- MIIEpAIBAAKCAQEA0le59pH7mp+XHxmkoEbX8SyXcZ+dmcyhrS1HbqtfnWVoSqai MrQijlIDv66bFDg9VnbFUKiXrcbzC+wVh8zuuy4Zl9OyvUEOC/YSHwaBvqMwPqgw nipCRoNNq3MQMBr7T6r7SWA0CCP2IPCl+q0W/HHI5LRk8FT7rGH/hdufwYn8rJxM B7jntBXMKZJzIQRMyVkZ0vlAla/2/t33dQVRLKNF8//G3wEKQL1yGMgmCXtAj/rn M96T4qIq4DpkELUFR52ql5SjSFZ3MLQ5Weyx81leLIJH5ikJ6N6pHQMNBRtW8Vw6 dypzhogjXb6tGlcjTxxlot6buzoT7MZRM9jWTwIDAQABAoIBAQC2mKk6vyen5vqN aPlcmaNEHe2qGWH67YU8jJ4CGIr8W9fZViZf1bhZzCCs+apuNxQoRxqrFm/1z0uW Ae/+34wuuapF/uSfHiZPg+HfRQrEr21mNyNdaln2VG3MdCqNWB7p3ggefoEsv+se VUoA/tmBdFVtFJy7dUq1Lq1fSnS40LhbprPFmbLEB9Q3/hNlWxsS1jk0NaaHQ6Qh lCUi3Weu9Yq8Ltuko4xqj98BIq/sYxp9X/i5qonJIMz3Pk9fxa19OTWXFi7vUfnY yBf6RBEBlXr5LJnAl7wpzeUbBHGog5Kx0+TmSwej//cVTvD5A10y99rmdfzKZ4/d wqcPrvcBAoGBAPwuFrV2Wd2JwIFyr3uDyZ0CXuaRfd06+mM4eAC5ANCQQ6Tksl+1 U8MXndeM23CN0vgW/cBjT8K6nJU98Gk5eMCBMMeNZF0GnDlj7x61VMRp3LuPZRrO FnhdR3FQdn7FTe2m962wz2E/awdCb+9Cx1WheUk/P3c8PmxYtBHTX+nhAoGBANWH Zkpb0Uu6Xhw5R3VgOCWXDuGC5UOU+vdXDh3L+KXG9CY+po2J+ak6T6wJfwSlmXT7 Zg71Z7nCVW/MwH3YonYdh0ddb16xUTrah8vHVNSw5L0vsyqx3g/fmdCSEDKKOQft eF9fGICZHna+daUqZEWYYCVqCxYF5u1x02jINaYvAoGAPmm5vReZjjb1qhQUUmF/ mJhpnG8N058xMTVcnfErvnK2Cy1+6CkcngBOVHbMKMMxH62xB9iMeQluj5FQ2voa ZKqUxA6+dDeamqmdGOCQJjx9IP6Qa13uOcP8VpMvgJicfOECE77a1Jq5hoZu5ayF YTAhsHsy3fPPD0m052SFLIECgYAWlDS61C6zhUeCUIQ/4ybMwsZuDjtUBCLtmKUD fZgTX5Bdou5VtStTO7lFBdQKl8A8YIEQP97yA5ypL8uDAy9ashCl+TlXmARw5r7J S5Cq1PG7F5oof5ptr0VCis9vqLITJoc9/n5GyuovwEAMcQkdWtl/21DEyWb74Lds Mw+JPQKBgQCiKGvd+YXzPgh3BJoguaMAIrcrlr0iGAEU5y2qi4xgqfyp4Wcb+RHx LAF7Uz2aT5oj4GP7HVBN7E2OyBe9TjOATnRRb+lSTKNMYYV20av5LaahtlN5URYu JC7glE/aMXR60Fx4E0iajzZpDKFyQSfc1TqReBQQF+qR0c5QeQSbRw== -----END RSA PRIVATE KEY-----
5.添加从节点
添加节点页面解释：
- 名称：自定义一个节点名称
- 执行器数量：可以同时执行的job线程数，随便写个数字
- 远程工作目：宿主机上Workspace目录
- 标签：自定义，方便后期识别
- 用法：尽可能的使用这个节点
- 启动方式：Launch agent agents via SSH
- 主机：输入要远程的宿主机IP地址
- Credentials：将Jenkins本机生成的SSH密钥的公钥发送至要远程的宿主机上，并且添加Jenkins主机的私钥key为凭据进行远程连接
- Host Key Verification Strategy：这项选择Known hosts file Verification Strategy
第二种方式：（ROOT账密连接）
1.添加远程主机的ROOT账号密码为凭据
2.添加从节点
添加节点页面解释：
- 名称：自定义一个节点名称
- 执行器数量：可以同时执行的job线程数，随便写个数字
- 远程工作目：宿主机上Workspace目录
- 标签：自定义，方便后期识别
- 用法：尽可能的使用这个节点
- 启动方式：Launch agent agents via SSH
- 主机：输入要远程的宿主机IP地址
- Credentials：添加要远程的宿主机的ROOT账号和密码的凭据
- Host Key Verification Strategy：这项选择Non verifying Verifcation Stragegy
