Two virtual machines ready to work:

1. Disable FIREWALLD for each machine:

Systemctl Stop Firewalld
Systemctl Disable FIREWALLD

2. Disable SELinux:

Vi/etc/selinux/config
#SELINUX =enforcing
Selinux=disabled
#也可用命令
Sed-i '/selinux/s/enforcing/disabled/'/etc/selinux/config

Start the service:
For SERVICES in Etcd kube-apiserver Kube-controller-manager Kube-scheduler; Do
Systemctl Restart $SERVICES
Systemctl Enable $SERVICES
Systemctl Status $SERVICES
Done

Define flannel network configuration to ETCD, this configuration will be pushed to the flannel service of each slave
Etcdctl mk/coreos.com/network/config ' {"Network": "172.17.0.0/16"} '

Slave: Installation and configuration of the machine

Installing Docker and updating reboots
Yum-y Install Docker
Yum-y Update
Reboot

Yum-y Install Kubernetes-node Flannel

Systemctl Restart $SERVICES
Systemctl Enable $SERVICES
Systemctl Status $SERVICES
Done

Login Master to confirm the status of Minions:

[[email protected] ~]# Kubectl get nodes
NAME LABELS STATUS
172.16.198.128 kubernetes.io/hostname=172.16.198.128 Ready

Note : If you need more than one slave node, you only need to repeat the operation on the Slava machine above .
