11、新增一个node节点步骤

本文以144为例子

11.1 参照三章系统常规参数配置

 更新hosts(所有节点)

vim /etc/hosts

192.168.22.141 k8s_master

192.168.22.142 k8s_node01

192.168.22.143 k8s_node02

192.168.22.144 k8s_node03

   

11.2 安装Docker 参照第五章

 

11.3 从node01复制文件到node03

scp -r /opt/kubernetes/  k8s_node03:/opt/

scp /usr/lib/systemd/system/{kubelet,kube-proxy}.service k8s_node03:/usr/lib/systemd/system/

11.3.1 替换node节点ip

cd /opt/kubernetes/cfg

                   

   

需要修改:kubelet,kubelet.config,kube-proxy文件ip

                  

 

11.3.2 删除node01认证信息

rm -rf /opt/kubernetes/ssl/*

 

11.3.3 启动kubelet,kube-proxy服务

systemctl start kubelet.service

systemctl enable kubelet.service

systemctl start kube-proxy.service

systemctl enable kube-proxy.service

   

11.3.4 master授权新加入node

# kubectl get csr

                  

# kubectl certificate approve node-csr-tE3KOFUjDDu1VLUZQNmEqwhdpRhU-RBRfWIIbAD3Xj8
