2.预检查和配置:
#2.1 Linux kernal检查[master和node节点均做]：
[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[[email protected] ~]# uname -a
Linux k8s-1 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
#2.2.修改hosts文件[master和node节点均做]
vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.133.44 k8s-1
192.168.133.45 k8s-2
#2.3安装docker，docker版本[master和node节点均做]：
yum -y install docker
systemctl enable docker
systemctl restart docker
systemctl restart network
systemctl status docker
[[email protected] ~]# docker version
Client:
Version: 1.12.6
API version: 1.24
Package version: docker-1.12.6-68.gitec8512b.el7.centos.x86_64
Go version: go1.8.3
Git commit: ec8512b/1.12.6

[[email protected] ~]#
3.关闭selinux[master和node节点均做]:
vi /etc/selinux/config
SELINUX=disabled
systemctl restart network
4.关闭firewalld,[master和node节点均做]:
systemctl stop firewalld
systemctl disable firewalld
systemctl restart network
systemctl status firewalld
5.编辑并添加如下内容[master和node节点均做]:
[[email protected] ~]#vi /etc/sysctl.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 1
systemctl restart network
6.安装[master节点]:
[[email protected] ~]#tar -xzvf k8s-v1.7.3.tar.gz
进入k8s-v1.7.3，运行sh generate.sh生成master文件及node文件目录到output
[[email protected] k8s-v1.7.3]# sh generate.sh
开始生成master所需文件，请稍等。。。
开始生成node所需文件，请稍等。。。
成功！请将output下master目录及node目录上传到要部署k8s集群的master节点及node节点，然后在node上执行kubeadm join命令加入集群
[[email protected] k8s-v1.7.3]#ls
config generate.sh image kubectl output repo script
[[email protected] k8s-v1.7.3]#cd output
[[email protected] k8s-v1.7.3]#ls
master node
[[email protected] k8s-v1.7.3]#
进入master目录，运行:
[[email protected] k8s-v1.7.3]#sh init.sh
###一定等到部署ok完node节点以后，用于把node节点加入进来：###
You can now join any number of machines by running the following on each node
as root:
kubeadm join --token e35778.736fd8c0e78e6e5c 192.168.133.44:6443

Your Kubernetes master has initialized successfully!
To start using your cluster, you need to run (as a regular user):
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
http://kubernetes.io/docs/admin/addons/
You can now join any number of machines by running the following on each node
as root:
kubeadm join --token e35778.736fd8c0e78e6e5c 192.168.133.44:6443
