1. 4台虚拟机 (CentOS Linux release 7.2.1511 (Core) ）
192.168.130.211 master
192.168.130.212 node1
192.168.130.213 node2
192.168.130.214 node3
2. 设置服务器hostname
2.1 设置本机 hostnamectl set-hostname master
2.2 vim /etc/hosts
192.168.130.211 master
192.168.130.212 node1
192.168.130.213 node2
192.168.130.214 node3
2.3 reboot
3.关闭防火墙、selinux和swap
systemctl stop firewalld systemctl disable firewalld setenforce 0 sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config swapoff -a sed -i 's/.*swap.*/#&/' /etc/fstab
4.配置内核参数，将桥接的IPv4流量传递到iptables的链
cat > /etc/sysctl.d/k8s.conf <<EOF net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF sysctl --system
5.配置国内yum源
yum install -y wget mkdir /etc/yum.repos.d/bak && mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo yum clean all && yum makecache
6.配置国内Kubernetes源
cat <<EOF > /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg EOF
6.配置 docker 源
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
