替换hostname
export HOSTNAME=node
hostnamectl set-hostname $HOSTNAME && reboot
vim /etc/hosts
安装tailscale
curl -fsSL https://tailscale.com/install.sh | sh
开启ip转发
echo 'net.ipv4.ip_forward = 1' | tee -a /etc/sysctl.d/99-tailscale.conf
echo 'net.ipv6.conf.all.forwarding = 1' | tee -a /etc/sysctl.d/99-tailscale.conf
sysctl -p /etc/sysctl.d/99-tailscale.conf
新建目录 将不同节点类型的config写入
mkdir -p /etc/rancher/k3s && vim /etc/rancher/k3s/config.yaml
安装k3s 此处注意安装类型 是server 还是 agent
curl -sfL https://get.k3s.io | \
INSTALL_K3S_VERSION=v1.30.2+k3s2 \
INSTALL_K3S_MIRROR=cn \
sh -s - server
国内安装加速 & 镜像加速地址
https://rancher-mirror.rancher.cn/k3s/k3s-install.sh
vim /etc/rancher/k3s/registries.yaml
查看serverToken 记得在config中替换最新的token
cat /var/lib/rancher/k3s/server/node-token
查看api server config 需要替换到.kube/config中 注意将其中的server地址替换为高可用地址
cat /etc/rancher/k3s/k3s.yaml
给node添加地域标签
kubectl label nodes tca topology.kubernetes.io/region=cn-sh
kubectl label nodes tca svccontroller.k3s.cattle.io/enablelb="true"
给master节点添加污点
kubectl taint nodes tca node-role.kubernetes.io/master:NoSchedule
节点网络优化
可以在需要加速的节点屏蔽目标ip 比如85.113.71.11 让tailscale强制走drep服务器进行加速
iptables -A OUTPUT -p udp --dport 41641 -d 85.113.71.11 -j DROP
