- 最低需求：要1台master宿主机 2台node节点机
- 配置为：2C 4G 60GB
1.修改节点名称（ip和名称匹配很重要 一开始不要出错喔~）
cat >> /etc/hosts <
2…关闭自动挂载
swapoff -a
sed -i '/ swap / s/^(.*)$/#1/g' /etc/fstab
3.关闭selinux以及防火墙
sed -ri 's#(SELINUX=).*#1disabled#' /etc/selinux/config
setenforce 0
systemctl disable firewalld && systemctl stop firewalld
4.开启内核对流量的转发
cat < /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward=1
vm.max_map_count=262144
EOF
5.
modprobe br_netfilter
sysctl -p /etc/sysctl.d/k8s.conf
6.配置docker-ce.repo
curl -o /etc/yum.repos.d/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/docker-ce.repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
7.配置kubernetes.repo
cat < /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
http://mirrors.aliyun.com/kubernetes/yum/doc/rpm package-key.gpg
EOF
8.清除缓存并且重启配置
yum clean all && yum makecache
