本文详细介绍如何从零开始搭建Kubernetes集群，包括关闭防火墙、SELinux、swap，修改内核参数，安装并配置Docker及Kubernetes组件，部署Flannel网络插件，以及在master节点上部署Dashboard的过程。

节点ip
10.0.0.4 master
10.0.0.5 node

在所有节点上执行

cat <<EOF >>/etc/hosts
10.0.0.4 master
10.0.0.5  node
EOF

关闭防火墙
systemctl stop firewalld &&  systemctl disable firewalld

关闭selinux
setenforce 0
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/sysconfig/selinux 
sed -i "s/^SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

关闭swap
swapoff -a
sed -i 's/.*swap.*/#&/' /etc/fstab

修改内核
cat <<EOF >  /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system

修改句柄
echo "* soft nofile 65536" >> /etc/security/limits.conf
echo "* hard nofile 65536" >> /etc/security/limits.conf
echo "* soft nproc 65536"  >> /etc/security/limits.conf
echo "* hard nproc 65536"  >> /etc/security/limits.conf
echo "* soft  memlock  unlimited"  >> /etc/security/limits.conf
echo "* hard memlock  unlimited"  >> /etc
