LINUX7-based k8s deployment (i)

1. Environment preparation

   #系统环境lsb_release -aDistributor ID: CentOSDescription:    CentOS Linux release 7.3.1611 (Core)Release:    7.3.1611Codename:   Core说明：如提示：-bash: lsb_release: command not found，请yum install -y redhat-lsb#查看selinux状态getenforceDisabled#docker 版本docker --versionDocker version 17.09.0-ce, build afdb6d4

2. Initializing configuration work
   Master and Node nodes because of division of labor, so the installation of different services, the final installation completed, Master and node start the core services are as follows:

Td>kube-scheduler

Master node	node node
etcd-master	kube-flannel
kube-apiserver	kube-proxy
Kube-con Troller-manager	Other apps
kube-proxy	--------
--------
kube-dns	--------
kube-flannel	--------
pause-amd64	--------

1. Base image (binary) (take v1.10.0 as an example):
   #说明:
   Do high availability must ensure that the master node is 2 and above, recommended 3 nodes!
   #下载kubernetes二进制文件
   Can be downloaded from kubernetes, generally need to download the server package, unzip the file, use the Docker load command to load the tar package into a usable image (if necessary to hit the tag you want).

   #下载：kubernetes-server-linux-amd64.tar.gzkubernetes-src.tar.gzkubernetes.tar.gz#解压缩tar zxf kubernetes-server-linux-amd64.tar.gzcd /data/k8s/kubernetes/server/bin#创建镜像docker load -i  kube-apiserver.tardocker load -i kube-controller-manager.tardocker load -i kube-scheduler.tardocker load -i kube-proxy.tar

   The list of individual images that #本次演示 kubernetes depends on is as follows:

Image Name	Version	Des (* required)
k8s.gcr.io/kube-apiserver	v1.10.0	*
K8s.gcr.io/kube-cont Roller-manager	v1.10.0	*

1. Running the Kubelet service

   #cp文件cp /data/k8s/kubernetes/server/bin/kubeadm   /usr/bin/cp /data/k8s/kubernetes/server/bin/kubectl      /usr/bin/cp /data/k8s/kubernetes/server/bin/kubelet      /usr/bin/#cp kubelet.service文件mkdir kubernetes-srctar zxf kubernetes-src.tar.gz -C ./kubernetes-src/cd /data/k8s/kubernetes-src/build/rpmscp ./kubelet.service  /etc/systemd/system/chmod 755  /etc/systemd/system/kubelet.service#修改kubelet.service文件[Unit]Description=kubelet: The Kubernetes Node AgentDocumentation=http://kubernetes.io/docs/[Service]ExecStart=/usr/bin/kubeletRestart=alwaysStartLimitInterval=0RestartSec=10[Install]WantedBy=multi-user.target#开启kubelet服务systemctl start  kubelet.servicesystemctl status kubelet.service
