k8s多节点master部署

多节点master2节点部署

从master01节点上拷贝证书文件、配置文件和服务管理文件到master02

scp -r /opt/etcd/ root@192.168.80.16:/opt/
scp -r /opt/kubernetes/ root@192.168.80.16:/opt
scp /usr/lib/systemd/system/{
   
   kube-apiserver,kube-controller-manager,kube-scheduler}.service root@192.168.80.16:/usr/lib/systemd/system/

修改配置文件kube-apiserver中的IP

vim /opt/kubernetes/cfg/kube-apiserver
KUBE_APISERVER_OPTS="--logtostderr=true \
--v=4 \
--etcd-servers=https://192.168.80.11:2379,https://192.168.80.12:2379,https://192.168.80.13:2379 \
--bind-address=192.168.80.16 \				#修改master02的ip
--secure-port=6443 \
--advertise-address=192.168.80.16 \			#修改master02的ip

在master02节点上启动各服务并设置开机自启

systemctl enable --now kube-apiserver.service
systemctl enable --now kube-controller-manager.service
systemctl enable --now kube-scheduler.service

查看node节点状态

ln -s /opt/kubernetes/bin/* /usr/local/bin/
kubectl get nodes
kubectl get nodes -o wide			#-o=wide：输出额外信息；对于Pod，将输出Pod所在的Node名
//此时在master02节点查到的node节点状态仅是从etcd查询到的信息，而此时node节点实际上并未与maste
