# Rke2单机快速部署Kubernetes
|
||
|
|
|
||
|
|
| 节点名称 | IP | Kubernetes角色 |
|
||
|
|
| :----------: | :----------: | :----------------------------------------: |
|
||
|
|
| k8s-master-1 | 192.168.1.10 | Controlplane,etcd,worker,keepalived-master |
|

|
## 环境准备
|
||
|
|
|
||
|
|
> !!!每次部署都写挺麻烦的索性都放在一个文件内了请查看 [Kubernetes基础环境准备](https://gitee.com/offends/Kubernetes/blob/main/%E9%83%A8%E7%BD%B2%E6%96%87%E6%A1%A3/Kubernetes%E5%9F%BA%E7%A1%80%E7%8E%AF%E5%A2%83%E5%87%86%E5%A4%87.md) ,请按照此文档初始化环境
|
||
|
|
|
||
|
|
### 所有节点执行
|
||
|
|
|
||
|
|
1. 更改主机名
|
||
|
|
|
||
|
|
```bash
|
||
|
|
hostnamectl set-hostname k8s-master-1 && bash
|
||
|
|
```
|
||
|
|
|
||
|
|
3. 在三台节点上配置 NetworkManager
|
||
|
|
|
||
|
|
- 配置 cali 和 flannel 的网卡不被 NetworkManager 管理
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mkdir -p /etc/NetworkManager/conf.d
|
||
|
|
```
|
||
|
|
|
||
|
|
内容如下
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cat <<EOF > /etc/NetworkManager/conf.d/rke2-canal.conf
|
||
|
|
[keyfile]
|
||
|
|
unmanaged-devices=interface-name:cali*;interface-name:flannel*
|
||
|
|
EOF
|
||
|
|
```
|
||
|
|
|
||
|
|
- 重启 NetworkManager
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl daemon-reload
|
||
|
|
systemctl restart NetworkManager
|
||
|
|
```
|
||
|
|
|
||
|
|
### 开始部署
|
||
|
|
|
||
|
|
[Rke2-Github-releases](https://github.com/rancher/rke2/releases)
|
||
|
|
|
||
|
|
1. 安装 RKE2
|
||
|
|
|
||
|
|
```bash
|
||
|
|
curl -sfL https://get.rke2.io | sh -
|
||
|
|
```
|
||
|
|
|
||
|
|
> - 使用国内源
|
||
|
|
>
|
||
|
|
> ```bash
|
||
|
|
> curl -sfL http://rancher-mirror.rancher.cn/rke2/install.sh | INSTALL_RKE2_MIRROR=cn INSTALL_RKE2_TYPE="server" sh -
|
||
|
|
> ```
|
||
|
|
>
|
||
|
|
> - 指定版本
|
||
|
|
>
|
||
|
|
> ```bash
|
||
|
|
> curl -sfL https://rancher-mirror.rancher.cn/rke2/install.sh | INSTALL_RKE2_MIRROR=cn INSTALL_RKE2_TYPE="server" INSTALL_RKE2_VERSION="v1.29.3+rke2r1" sh -
|
||
|
|
> ```
|
||
|
|
|
||
|
|
2. 开始部署主节点
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl enable rke2-server.service
|
||
|
|
systemctl start rke2-server.service
|
||
|
|
```
|
||
|
|
|
||
|
|
> 启动失败查看日志
|
||
|
|
>
|
||
|
|
> ```bash
|
||
|
|
> rke2 server --config /etc/rancher/rke2/config.yaml --debug
|
||
|
|
> ```
|
||
|
|
|
||
|
|
3. 配置 RKE2 可执行文件加入到系统的 PATH 中
|
||
|
|
|
||
|
|
```bash
|
||
|
|
echo "export PATH=$PATH:/var/lib/rancher/rke2/bin" >> /etc/profile && source /etc/profile
|
||
|
|
```
|
||
|
|
|
||
|
|
4. 配置 config 文件
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mkdir ~/.kube && cp /etc/rancher/rke2/rke2.yaml ~/.kube/config
|
||
|
|
```
|
||
|
|
|
||
|
|
5. 验证
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl get node
|
||
|
|
```
|
||
|
|
|
||
|
|
6. 配置 crictl 软链接
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ln -s /var/lib/rancher/rke2/agent/etc/crictl.yaml /etc/crictl.yaml
|
||
|
|
```
|
||
|
|
|
||
|
|
7. 验证
|
||
|
|
|
||
|
|
```bash
|
||
|
|
crictl ps
|
||
|
|
```
|
||
|
|
|
||
|
|
## 卸载节点
|
||
|
|
|
||
|
|
1. 停止 Rke2
|
||
|
|
|
||
|
|
```bash
|
||
|
|
rke2-killall.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
2. 卸载 Rke2
|
||
|
|
|
||
|
|
```bash
|
||
