关闭 swap
1)、swapoff -a
(2)、vim /etc/sysconfig/kubelet
KUBELET_EXTRA_ARGS="--fail-swap-on=false"
. 安装docker
sudo vi /usr/lib/systemd/system/docker.service
Environment="HTTPS_PROXY=www.ik8s.io:10070"
Environment="NO_PROXY=127.0.0.1/8,172.18.0.0/16"
Environment=PATH=/usr/libexec/docker:/usr/bin:/usr/sbin
systemctl daemon-reload
systemctl restart docker
2.配置桥
sudo sysctl -a |grep bridge
sudo touch /etc/sysctl.d/k8s.conf
sudo chmod 777 /etc/sysctl.d/k8s.conf
sudo cat <<EOF > /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
EOF
sudo sysctl -p /etc/sysctl.d/k8s.conf
3.安装k8s
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
kubernetes

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
sudo setenforce 0
sudo yum install -y kubelet kubeadm kubectl
sudo systemctl enable kubelet && systemctl start kubelet
yum --list |grep "^kubernetes"
iptable -vnl
sudo docker login --username=17809211858 registry.cn-hangzhou.aliyuncs.com
sudo kubeadm config print init-defaults > kubeadm.conf
kubeadm config images pull --config kubeadm.conf
#指定额外的初始化信息，下面表示禁用操作系统的swap功能
cat /etc/sysconfig/kubelet KUBELET_EXTRA_ARGS="--fail-swap-on=false"
sudo kubeadm init \
--apiserver-advertise-address=192.168.233.128 \
--image-repository registry.aliyuncs.com/google_containers \
--kubernetes-version v1.28.2 \
--service-cidr=10.1.0.0/16 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors="swap"
sudo kubeadm init --kubernetes-version="v1.18.2" --pod-network-cidr="10.244.0.0/16" --ignore-preflight-errors="swap" -skip-preflight-checks
kubectl get node
