我们的演示中，工作站和节点的IP地址如下：
- 工作站 – 192.168.31.154 (hostname: qikegu)
- 节点 – 192.168.31.100 (hostname: qikegu2)

添加节点
在工作站中，执行Knife Bootstrap命令将节点添加到服务器，命令中指定了Chef节点的IP地址及名称。
切换到/root/chef-repo目录，执行：
knife bootstrap 192.168.31.100 --connection-user root --connection-password your_password --node-name chefNode
