更好的识别

vim /etc/hosts

192.168.1.2 test1

192.168.1.2 test2

关闭swap

swapoff -a

fstab 删除 swap

vim /etc/fstab

关闭selinux

vim /etc/selinux/config

SELINUX=disable

setenforce = 0

关闭防火墙

systemctl stop firewalld.service

systemctl disable firewalld.service

开启ip转发功能

vim /etc/sysctl.conf

net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1

modprobe br_netfilter
sysctl -p

更换k8s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

# 将 SELinux 设置为 permissive 模式（相当于将其禁用）
sudo setenforce 0
sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

sudo yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

sudo systemctl enable --now kubelet

开机启动

[root@localhost ~]# systemctl enable kubelet



#添加模块
[root@localhost ~]#vim /etc/modules-load.d/containerd.conf

overlay
br_netfilter

[root@localhost ~]# modprobe overlay
[root@localhost ~]# modprobe br-netfilter

加载docer源(可以更换为阿里源)

sudo yum install -y yum-utils

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

安装 containerd

[root@localhost ~]# yum -y install containerd.io

[root@localhost ~]# mkdir -p /etc/containerd
[root@localhost ~]# containerd config default | sudo tee /etc/containerd/config.toml

vim /etc/containerd/config.toml

#95 行添加
SystemdCgroup = true

[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart containerd
[root@localhost ~]# systemctl enable containerd

#初始化
[root@localhost ~]# kubeadm init --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=10.168.1.181 --image-repository=registry.aliyuncs.com/google_containers
