Binary deployment of K8s cluster

Configure the nfs server

NFS_SERVER () {yum install-y nfs-utils rpcbindmkdir-pv / nfssystemctl restart nfs rpcbindsystemctl enable nfs rpcbindecho'/ nfs * (rw,no_root_squash)'> / etc/exportsexportfs-ravcd / nfs}

1. The client of nfs sharing

NFS_CLIENT () {yum install-y nfs-utils rpcbindsystemctl restart nfs rpcbindsystemctl enable nfs rpcbindmkdir-pv / nfsshowmount-e 192.168.11.11mount.nfs 192.168.11.11:/nfs / nfsdf-hT}

2. Hostname setting

HOST_NAME () {read-p 'please inpute hostname (eg.srv11):' NAMEHOSTNAME=$ {NAME} hostnamectl-- static set-hostname $HOSTNAMEhostname# modify hosts file grep-E 'node | srv | dk.io' / etc/hosts | | echo' 192.168.11.11 node1 k8s-master srv11192.168.11.12 node2 k8s-node1 srv12192.168.11.13 node3 k8s-node2 srv13192.168.11.14 node4 k8s-node3 srv14192.168.11.11 dk.io' > > / etc/hostscat / etc/hosts}

3. Installation and configuration of etcd and flannel

ETCD_INST () {\ cp-fv / nfs/k8s/k8s.repo / etc/yum.repos.d/yum install-y etcd flannel [- f / etc/etcd/etcd.conf.bak] | | cp-v / etc/etcd/etcd.conf {, .bak} cd/etc / etcd# remove the number # sed-I's cd/etc at the beginning of lines 5, 20, 26, 27, 28. 27s/ ^ # / /; 28s/ ^ # / /; 'etcd.confegrep-nv' ^ # | ^ $'etcd.confsed-I "9 etcd.confsed 26slob defaultlop ${HOSTNAME} /;" etcd.confsed-I "20J 21sLash 0.0.0.0lash ${HOSTNAME} / "etcd.confegrep-nv'^ # | ^ $'etcd.confCluster='ETCD_INITIAL_CLUSTER=" srv11= http://srv11:2380,srv12=http://srv12:2380,srv13=http://srv13:2380"'sed-I "26c ${Cluster}" etcd.confegrep-nv' ^ # | ^ $'etcd.confsed-I' 4s hash 127.0.0.1 / etc/sysconfig/flanneldcat / etc/sysconfig/flanneld

4. Start the etcd service

Systemctl enable etcdsystemctl restart etcdetcdctl get / atomic.io/network/config [$?-eq 0] | | etcdctl mk / atomic.io/network/config'{"Network": "10.0.0.0amp 16"} 'systemctl enable flanneldsystemctl restart flanneld}

5. Install the k8s-master server

K8S_MASTER () {yum install-y docker kubernetessystemctl restart dockersystemctl enable dockerdocker info

6. Modify scripts for apiserver and config files

Cd / etc/kubernetes/sed-I '11s/ ^ # /; 14s/ ^ # / /' apiserversed-I'8s 22s/127.0.0.1/srv11/ 127.0.0.1G 'apiserversed-I "17s 22s/127.0.0.1/srv11/ ${HOSTNAME} /" apiserversed-I "23s 22s/127.0.0.1/srv11/ 22s/127.0.0.1/srv11/ configgrep-Ev' ^ $| ^ # 'apiservercd / etc/kubernetes/sed-I" 22s/127.0.0.1/srv11/ "ServiceAccountMague /" SecurityContextDenyServiceAccountMague / "SecurityContextDenyServiceAccountMagneEffect /" SecurityContextDenyServiceAccountTime / "SecurityContextDenyServiceAccoun

7. K8s-master starts the service and sets boot self-startup

Systemctl enable docker.servicesystemctl restart docker.servicesystemctl enable kube-apiserver.servicesystemctl restart kube-apiserver.servicesystemctl enable kube-controller-manager.servicesystemctl restart kube-controller-manager.servicesystemctl enable kube-scheduler.servicesystemctl restart kube-scheduler.servicekubectl get nodes

8. Visit http://kube-apiserver:port, to view all request url and creation status

Curl http://192.168.11.11:8080 curl http://192.168.11.11:8080/healthz/ping}

9. K8s-node node deployment

# install docker and kubernets (refer to the installation method of k8s-master)

K8S_NODE () {yum install-y docker kubernetessystemctl restart dockersystemctl enable dockerdocker info

10. Modify scripts for config and kubelet files

Cd / etc/kubernetes/MASTER='srv11'sed-I "22s8s/ 127.0.0.1 HOSTNAME ${MASTER} /" configgrep-Ev'^ $| ^ # 'configcd / etc/kubernetes/sed-I "5s/127.0.0.1/0.0.0.0/" kubeletsed-I' 8s/ ^ # / / 'kubeletsed-I "11s HOSTNAME} /" kubeletsed-I "14s/127.0.0.1/srv11/" kubeletgrep-Ev' ^ $| ^ # 'kubelet

11. K8s-node1 starts the service and sets boot self-startup

Systemctl enable docker.servicesystemctl restart docker.servicesystemctl enable kubelet.servicesystemctl restart kubelet.servicesystemctl enable kube-proxy.servicesystemctl restart kube-proxy.servicekubectl-s http://srv11:8080 get nodes}

12. K8s cluster status detection

K8S_STAT () {etcdctl member listetcdctl cluster-healthkubectl-s http://srv11:8080 get node} cat
