|
+## 部署前言
|
|
|
+
|
|
|
+长亭科技的雷池开源WAF(Web Application FireWalld)是一款足够简单、足够好用、足够强的免费 WAF。基于业界领先的语义引擎检测技术，作为反向代理接入，保护你的网站不受黑客攻击。
|
|
|
+
|
|
|
+至文档编写时官方开源版本与专业版并不支持HA高可用与集群模式部署。因需在生产环境部署故考虑架构必须至少是HA高可用，而官方不支持，仅在社区中发现有人编写过K8S集群中通过HelmChart的部署方案。
|
|
|
+
|
|
|
+耗时长达一个月对开源版本的测试部署，最终部署方案采用在k3s集群之上采用HelmChart部署，Chart中镜像完全采用官方原镜像不做任何改动。
|
|
|
+
|
|
|
+尽管如此，运行在k3s集群中的雷池WAF服务有且只能有一个POD副本，如有多个副本会导致某些功能异常，如：控制面板首页无访问计数变动、业务能正常转发但入侵行为无法正常检测与拦截。
|
|
|
+
|
|
|
+**目前此文档仅实现了WAF服务运行在K3S集群多个节点上，如有节点宕机，节点上的服务可自动切换至其它节点继续运行，并未实现服务多POD副本负载均衡。**

|
|
+## 部署前准备
|
|
|
+
|
|
|
+准备3台服务器，配置在4C8G，生产环境建议采用8C16G及以上配置，操作系统为Ubuntu22.04，作为K3S集群的服务器。在K3S集群的基础上部署雷池WAF。当前文档配置信息如下：
|
|
|
+| 主机名 | 主机IP | 用途 |
|
|
|
+|:----:|:----:|:----:|
|
|
|
+| waf-lan-k3s-master| 192.168.1.9 | K3S集群的master节点 |
|
|
|
+| waf-lan-k3s-node1| 192.168.1.7 | K3S集群的node1节点 |
|
|
|
+| waf-lan-k3s-node2| 192.168.1.8 | K3S集群的node2节点 |
|
|
|
+
|
|
|
+## 部署K3S集群
|
|
|
+### 部署k3s-Master节点服务
|
|
|
+#### 脚本部署master节点服务
|
|
|
+安装k3s版本对标k8s-1.28.8版本，在部署同时禁用自带的traefik网关与local-storage的存储类型
|
|
|
+
|
|
|
+```shell
|
|
|
+curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn INSTALL_K3S_VERSION=v1.28.8+k3s1 sh -s - --disable traefik --disable local-storage
|
|
|
+kubectl get nodes -owide #查看集群信息
|
|
|
+kubectl get pod -A #查看集群pod启动情况
|
|
|
+```
|
|
|
+
|
|
|
+> 参照官方部署文档如下：
|
|
|
+> https://docs.k3s.io/zh/quick-start
|
|
|
+> https://docs.k3s.io/zh/installation/configuration
|
|
|
+> 可部署升级的k3s版本，请查询官方如下地址：
|
|
|
+> https://update.k3s.io/v1-release/channels
|
|
|
+
|
|
|
+> 安装完毕后会有如下实用工具:
|
|
|
+> kubectl、crictl、ctr、k3s-killall.sh 和 k3s-uninstall.sh
|
|
|
+
|
|
|
+
|
|
|
+
|
|
|
+#### 调整集群kubeconfig文件
|
|
|
+- **k3s默认的kubeconfig文件存放路径：**
|
|
|
+
|
|
|
+```shell
|
|
|
+ls -l /etc/rancher/k3s/k3s.yaml
|
|
|
+```
|
|
|
+- **解决k3s下默认无/root/.kube/config文件问题**
|
|
|
+```shell
|
|
|
+echo "export KUBECONFIG=/etc/rancher/k3s/k3s.yaml" >> /etc/profile
|
|
|
+source /etc/profile
|
|
|
+mkdir -p /root/.kube/
|
|
|
+ln -sf /etc/rancher/k3s/k3s.yaml /root/.kube/config
|
|
|
+cat /root/.kube/config #查看kubeconfig文件内容
|
|
|
+```
|
|
|
+
|
|
|
+#### 配置k3s集群中的私有仓库信息
|
|
|
+默认k3s集群中containerd中配置docker镜像的私有仓库地址为空，加速地址为默认的dockerhub仓库域名，必须手动进行指定才能正常拉取私有仓库中的容器镜像与使用国内镜像加速源。
|
|
|
+k3s集群中自定义私有仓库地址，需要在master节点服务器上的`/etc/rancher/k3s`目录中新建registries.yaml文件。
|
|
|
+在此文档中registries.yaml文件内容如下(注意：此文件中的密码值不是真实存在的)：
|
|
|
+```yaml
|
|
|
+mirrors:
|
|
|
+ "docker.io":
|
|
|
+ endpoint:
|
|
|
+ - "http://192.168.1.138:5000"
|
|
|
+ - "https://tshf4sa5.mirror.aliyuncs.com"
|
|
|
+ "harbor.scmttec.com":
|
|
|
+ endpoint:
|
|
|
+ - "https://harbor.scmttec.com"
|
|
|
+configs:
|
|
|
+ "harbor.scmttec.com":
|
|
|
+ auth:
|
|
|
+ username: "robot$pull_image"
|
|
|
+ password: "b9RCmoH5vN5ZA0"
|
|
|
+ tls:
|
|
|
+ insecure_skip_verify: false
|
|
|
+```
|
|
|
+文件存放好以后，重启k3s服务使配置生效
|
|
|
+```shell
|
|
|
+systemctl restart k3s
|
|
|
+```
|
|
|
+
|
|
|
+#### 安装helm工具
|
|
|
+- **helm官方下载工具压缩包并解压安装**
|
|
|
+
|
|
|
+下载页面：https://github.com/helm/helm/releases
|
|
|
+下载地址：https://get.helm.sh/helm-v3.12.0-linux-amd64.tar.gz
|
|
|
+
|
|
|
+```shell
|
|
|
+wget https://get.helm.sh/helm-v3.12.0-linux-amd64.tar.gz
|
|
|
+tar zxf helm-v3.12.0-linux-amd64.tar.gz
|
|
|
+cp ./linux-amd64/helm /usr/local/bin/
|
|
|
+rm -rf ./linux-amd64/ #删除解压出来的目录
|
|
|
+```
|
|
|
+- **配置helm命令和kubectl命令的自动补全功能**
|
|
|
+```shell
|
|
|
+echo "source <(kubectl completion bash)" >> /etc/profile #添加kubectl命令自动补全
|
|
|
+echo "source <(helm completion bash)" >> /etc/profile #添加helm命令自动补全
|
|
|
+source /etc/profile #让功能立即生效
|
|
|
+```
|
|
|
+- **查看helm命令是否能正常使用**
|
|
|
+```shell
|
|
|
+helm list -n kube-system
|
|
|
+#显示如下信息：
|
|
|
+NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
|
|
|
+traefik kube-system 1 2023-05-29 06:39:26.751316258 +0000 UTC deployed traefik-21.2.1+up21.2.0 v2.9.10
|
|
|
+traefik-crd kube-system 1 2023-05-29 06:39:22.816811082 +0000 UTC deployed traefik-crd-21.2.1+up21.2.0 v2.9.10
|
|
|
+```
|
|
|
+
|
|
|
+### 部署k3s-Node节点服务
|
|
|
+#### 获取k3s-Master节点的token文件
|
|
|
+在部署k3s-node节点服务即k3s-agent服务之前，需要获取k3s-server服务的token文件，文件位置为master节点的/var/lib/rancher/k3s/server/token文件，在master节点执行如下命令获取token值：
|
|
|
+```shell
|
|
|
+cat /var/lib/rancher/k3s/server/token
|
|
|
+#显示结果如下：
|
|
|
+K10f890abb83ce8cdf8b5dbeff8edb628d10cc53c23fa9f56152db0cf22454546bf::server:fec37548170a2affec1e3ebd1fdf708d
|
|
|
+```
|
|
|
+
|
|
|
+#### 通过官方脚本直接安装k3s-agent服务
|
|
|
+k3s官方有k3s-agent服务的安装脚本，通过curl直接进行安装，在安装的同时指定server即master节点的IP地址与token值。
|
|
|
+在2台Node节点服务器上直接执行命令如下：
|
|
|
+```shell
|
|
|
+curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn INSTALL_K3S_VERSION=v1.28.8+k3s1 K3S_URL=https://192.168.1.9:6443 K3S_TOKEN=K10f890abb83ce8cdf8b5dbeff8edb628d10cc53c23fa9f56152db0cf22454546bf::server:fec37548170a2affec1e3ebd1fdf708d sh -
|
|
|
+```
|
|
|
+执行后在master节点通过kubectl命令查看新加节点状态：
|
|
|
+```shell
|
|
|
+kubectl get nodes -owide
|
|
|
+# 显示结果如下：
|
|
|
+NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME

|
|
|
+```
|
|
|
+> 至此K3S集群基础服务已成功部署完毕！

|
+## 安装k3s集群存储与网关组件
|
|
|
+### 安装Nginx-Ingress组件
|
|
|
+通过nginx-ingress官方github站点获取最新安装版本及文件，并对官方部署文件进行修改后得出最终文件nginx-ingress-v1.10.0.yaml。

+### 通过HelmChart安装nfs-provisioner组件
|
|
|
+nfs-subdir-external-provisioner服务为K8S或K3S集群自动挂载NFS目录，作为集群后端持久化数据存储使用的一个第三方组件。
|
|
|
+本文中将采用HelmChart的方式进行部署并生成集群的stroage-class存储类型。
|
|
|
+#### 增加helm的公共远程仓库并部署
|
|
|
+```shell

|
|
+helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/

|
|
|
+查看HelmChart中NFS相关的版本信息
|
|
|
+```shell

|
|
|
+helm search repo nfs-subdir-external-provisioner|grep nfs-subdir-external-provisioner

|
|
|
+#安装nfs命令客户端
|
|
|
+apt install -y nfs-common
|
|
|
+#注意：如果要使用NFS作为后端存储，已Ubuntu系统为例，所有集群节点都必须安装NFS客户端，否则无法进行挂在NFS存储
|
|
|
+```
|
|
|
+安装nfs-client-provisioner
|
|
|
+```shell
|
|
|
+helm install --namespace kube-system nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner \

|
|
|
+> nfs.path为NFS服务器共享出来的目录路径
|
|

|
|
|
+> storageClass.defaultClass为是否设置为集群的默认存储类型
|

+## Helm部署雷池WAF服务
|
|
|
+雷池WAF官方仅支持docker单机容器化部署，社区内有人提供了一个helmchart的部署方案，此文档中按照第三方的helmchart的部署方案进行部署。当前第三方的仓库在文档顶部已由链接，此处不再赘述。
|
|
|
+### master节点拉取helmchart的tgz包
|
|
|
+直接通过命令进行拉取
|
|
|
+```shell

|
|
+helm repo add safeline "https://g-otkk6267-helm.pkg.coding.net/Charts/safeline"
|
|
|
+helm repo update
|
|
|
+helm fetch --version 5.2.0 safeline/safeline
|
|
|
+```
|
|
|
+### 创建values文件
|
|
|
+直接通过命令创建values.yaml文件，文件内容如下：
|
|
|
+```yaml
|
|

|
|
|
+```
|
|
|
+> 至此helm部署雷池开源WAF服务已成功，可通过k3s-node节点的IP+safeline-mgt暴露的NodePort端口进行访问雷池WAF控制台，此文档中为：https://192.168.1.9:31443
|
|
|
+
|
|
|
+## Nginx-Ingress接入防护站点域名至WAF
|
|
|
+### Nginx-Ingress的选择说明
|
|
|
+登录雷池开源WAF服务后，需要在防护站点中配置需要接入WAF的防护站点，以及接入WAF后的上级代理转发IP或域名。
|
|
|
+所有的接入站点均通过`safeline-tengine`服务进行接入转发，因雷池WAF部署在kubernetes集群中
|
|
|
+**就算将`safeline-tengine`服务通过NodePort暴露出去后，如果将域名直接指向node节点的公网IP+NodePort端口，tengine服务也获取不到`X-Forwarded-For`的header头部信息，只能通过网络获取，而网络获取的IP仅只能显示kubernetes的内网POD的IP，不是真实的客户端公网IP。**
|
|
|
+**获取不到`X-Forwarded-For`字段的nginx访问日志示例,以及通过网络只能获取到内网IP：10.42.1.1：**
|
|
|
+```
|
|
|
+10.42.1.1 - - [16/Apr/2024:16:52:36 +0800] "www.abc.com" "GET /message-ajaxGetMessage-0.html HTTP/1.1" 200 0 "https://www.abc.com/my/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36" ""
|
|
|
+```
|
|
|
+故只能通过Nginx-Ingress来进行转发至WAF的safeline-tengine服务，此时safeline-tengine服务才能获取到`X-Forwarded-For`的头部信息,可以获取到真实的客户端公网IP地址，**只有获取到客户端真实IP后才能做封堵以及黑白名单规则。**
|
|
|
+> 雷池WAF控制台中的“防护站点”-“代理配置”中“源 IP 获取方式”设置为“从HTTP Header中获取”，下面的Header值为:`X-Forwarded-For`
|
|
|
+
|
|
|
+**获取到nginx-ingress中转发过来的`X-Forwarded-For`字段的tengine中访问日志示例：**
|
|
|
+```
|
|
|
+10.42.1.1 - - [16/Apr/2024:16:52:36 +0800] "www.abc.com" "GET /message-ajaxGetMessage-0.html HTTP/1.1" 200 0 "https://www.abc.com/my/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36" "222.234.923.56"
|
|
|
+```
|
|
|
+> 除Nginx-Ingress可以实现客户端真实IP外，k3s自带的teafik也能实现，但需要做一定的修改，感兴趣的可自行研究此处再做赘述。
|
|
|
+
|
|
|
+
|
|
|
+### Nginx-Ingress配置举例
|
|
|
+此文档中比如需要配置`www.abc.com`域名的接入，除雷池WAF的防护站点需配置外，还需要创建Nginx-Ingress关于该域名的资源清单文件。kubernetes中的资源清单详细解读，请参见kubernetes官方网站。
|
|
|
+> 除Nginx-Ingress配置外，在雷池WAF控制台还需要做一些类似防护站点等配置，此处不赘述，详情参见雷池WAF官方文档。
|
|
|
+
|
|
|
+
|
|
|
+此清单文件包含如下2个方面：
|
|
|
+- 域名证书文件资源清单文件，即kubernetes的secret类型
|
|
|
+
|
|
|
+文件举例(证书内容通过了base64加密后的值，示例中的值不是真实存在的)：
|
|
|
+```yaml

|
|
|
+
|
|
|
+- Ingress资源清单文件，即绑定指定域名、域名证书以及Ingress后端转发svc使用
|
|
|
+
|
|
|

|
|
|
+
|
|
|
+### 应用该配置并查看访问情况
|
|
|
+- 通过`kubectl`命令来应用以上创建的两个yaml文件
|
|
|
+```shell
|
|
|
+kubectl apply -f www-abc-com-secret.yaml
|
|
|
+kubectl apply -f www-abc-com-ingress.yaml
|
|
|
+```
|

|
|
|
+
|
|
|
+## 测试攻击防护
|
|
|
+此处以`www.abc.com`域名为例，首先此域名需解析到WAF所在的k3s集群节点服务器IP上。
|
|
|
+攻击语句举例：
|
|
|
+```shell
|
|
|
+curl -v https://www.abc.com/\?id\=3%20AND%201\=1
