### 替换hostname
|
|
```shell
|
|
export HOSTNAME=node
|
|
hostnamectl set-hostname $HOSTNAME && reboot
|
|
vim /etc/hosts
|
|
```
|
|
|
|
### 安装tailscale
|
|
```shell
|
|
curl -fsSL https://tailscale.com/install.sh | sh
|
|
```
|
|
|
|
### 开启ip转发
|
|
```shell
|
|
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
|
|
```shell
|
|
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
|
|
```shell
|
|
curl -sfL https://get.k3s.io | \
|
|
INSTALL_K3S_VERSION=v1.30.5+k3s1 \
|
|
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
|
|
|
|
```shell
|
|
vim /etc/rancher/k3s/registries.yaml
|
|
```
|
|
|
|
### 查看serverToken 记得在config中替换最新的token
|
|
```shell
|
|
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
|
|
```shell
|
|
cat /etc/rancher/k3s/k3s.yaml
|
|
```
|
|
|
|
### 给node添加地域标签
|
|
```shell
|
|
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
|
|
```shell
|
|
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
|
|
```shell
|
|
iptables -A OUTPUT -p udp --dport 41641 -d 85.113.71.11 -j DROP
|
|
```
