1.配置Jenkins主节点

主节点就是按照Jenkins节点
在Jenkins主节点中生成SSH密钥对，并将公钥添加到目标节点的authorized_keys文件中。

1.确认 Jenkins Pod 名称

[root@master var]# kubectl get pods -n devops-tools
NAME                      READY   STATUS    RESTARTS   AGE
jenkins-b96f7764f-drtz2   1/1     Running   0          52m

2.进入 Jenkins Pod：

[root@master var]# kubectl  exec -it  jenkins-b96f7764f-drtz2 -n devops-tools -- /bin/bash
jenkins@jenkins-b96f7764f-drtz2:/$ ls
bin  boot  dev	etc  home  lib	lib64  media  mnt  opt	proc  root  run  sbin  srv  sys  tmp  usr  var

3.生成SSH密钥对

jenkins@jenkins-b96f7764f-drtz2:~$ ssh-keygen -t rsa -b 4096 -C "jenkins" -f /var/jenkins_home/.ssh/id_rsa -N ""
Generating public/private rsa key pair.
/var/jenkins_home/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Your identification has been saved in /var/jenkins_home/.ssh/id_rsa
Your public key has been saved in /var/jenkins_home/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:1cqf53fIpx1kkDTUvFQ3ARMw75RbhBUdOozweab6mhI jenkins
The key's randomart image is:
+---[RSA 4096]----+
|         . ooBBBO|
|          o.B.B++|
|          .+.%...|
|         o .* =. |
|        S o. o o |
|       E  .. .o  |
|        ..  o..o |
|       .  o  oo.=|
|        .o..  o+o|
+----[SHA256]-----+

4.将公钥复制到目标节点：

jenkins@jenkins-b96f7764f-drtz2:~$ ssh-copy-id -i /var/jenkins_home/.ssh/id_rsa.pub root@172.16.103.197
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/var/jenkins_home/.ssh/id_rsa.pub"
/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
root@172.16.103.197's password: Number of key(s) added: Now try logging into the machine, with:   "ssh 'root@172.16.103.197'"
and check to make sure that only the key(s) you wanted were added.

2.配置Jenkins的node1节点

1.安装java

在目标节点（172.16.103.197）上安装 Java 11 或更高版本：

root@node1 bin]# sudo yum install java-11-openjdk -y上次元数据过期检查：1:27:01 前，执行于 2024年08月05日 星期一 04时00分42秒。
依赖关系解决。

2.配置 Jenkins node1节点的 Java 路径

1.添加Java环境变量

[root@node1 bin]# vim /etc/profile
#行尾添加
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.23.0.9-3.oc8.x86_64
export PATH=$JAVA_HOME/bin:$PATH

2.生效Java环境变量

[root@node1 bin]# source  /etc/profile
[root@node1 bin]# java -version
openjdk version "11.0.23" 2024-04-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.23.0.9-2) (build 11.0.23+9-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.23.0.9-2) (build 11.0.23+9-LTS, mixed mode, sharing)
[root@node1 bin]# 

3.Jenkins网页页面添加node1节点

1.创建node1节点

2.设置node1节点

生成的密钥：
复制到你添加的Key里

jenkins@jenkins-b96f7764f-drtz2:~$ cat /var/jenkins_home/.ssh/id_rsa

保存，然后刷新当前页面
