前言：
如今我们对“centos上安装minion”大概比较重视，兄弟们都需要知道一些“centos上安装minion”的相关知识。那么小编在网摘上网罗了一些有关“centos上安装minion””的相关内容，希望我们能喜欢，朋友们快快来学习一下吧！一，Kubernetes安装
master 节点安装 etcd package
yum install
systemctl disable iptables-services firewalld
systemctl stop iptables-services firewalld
每个节点上修改kubernetes配置文件
vi /etc/kubernetes/config
# How the controller-manager, scheduler, and proxy find the apiserver
KUBE_MASTER="--master=;
KUBE_ETCD_SERVERS="--etcd_servers=;
Master节点上 vi /etc/kubernetes/apiserver
# The address on the local server to listen to.
KUBE_API_ADDRESS="--address=0.0.0.0"
KUBE_API_PORT="--port=8080"
# Comma separated list of nodes in the etcd cluster
#KUBE_ETCD_SERVERS="--etcd_servers=;
Master节点启动相关kubernetes服务
for SERVICES in etcd kube-apiserver kube-controller
manager kube-scheduler; do
systemctl restart $SERVICES
systemctl enable $SERVICES
systemctl status $SERVICES
done
for SERVICES in etcd kube-apiserver kube-controller
manager kube-scheduler; do
systemctl status $SERVICES
done
Node节点修改/etc/kubernetes/kubelet
###
# kubernetes kubelet (minion) config
KUBELET_ADDRESS="--address=0.0.0.0"
KUBELET_PORT="--port=10250"
KUBELET_HOSTNAME="--hostname_override=centos-minion"
KUBELET_API_SERVER="--api_servers=“
# Add your own!
KUBELET_ARGS=""
tail -f /var/log/messages |grep kube
在master节点执行kubectl get nodes
查看到节点注册成功，则表明系统安装正常
[root@centos-master yum.repos.d]# kubectl get nodes
NAME LABELS STATUS
centos-minion kubernetes.io/hostname=centos-minion Ready
[root@centos-master yum.repos.d]# kubectl cluster-info
Kubernetes master is running at
二，Kubernetes基本命令
Master上的kubectrl命令为管理集群的命令
kubectl describe --help
三，Hello world
