k3s安装ragflow

一、    k3s安装

1.1 修改hostname

hostnamectl set-hostname <hostname>

1.2 关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

1.3 关闭selinux

setenforce 0
sed -i 's/enforcing/disabled/' /etc/selinux/config

1.4 关闭swap分区

sudo swapoff -a #临时禁用所有swap分区

编辑/etc/fstab文件并注释掉swap分区的相关行，或者直接删除swap分区的相关行。

1.5 准备安装文件

install.sh：https://github.com/k3s-io/k3s/blob/v1.25.16%2Bk3s4/install.sh
k3s：https://github.com/k3s-io/k3s/releases/tag/v1.25.16%2Bk3s4
镜像k3s-airgap-images-amd64.tar.gz：https://github.com/k3s-io/k3s/releases/tag/v1.25.16%2Bk3s4

1.6 执行安装脚本

将 tar 文件放在images目录下

sudo mkdir -p /var/lib/rancher/k3s/agent/images/
sudo cp ./k3s-airgap-images-$ARCH.tar /var/lib/rancher/k3s/agent/images/

  将 k3s文件放在/usr/local/bin/目录下

cp k3s /usr/local/bin/
chmod +x /usr/local/bin/k3s

执行安装脚本

chmod +x install.sh
INSTALL_K3S_SKIP_DOWNLOAD=true ./install.sh

1.7 K3S修改NodePort范围

systemctl stop k3s

vi /etc/systemd/system/k3s.service  # 修改配置，保存并退出
      #配置文件修改如下，修改ExecStart后内容
  ExecStart=/usr/local/bin/k3s \
    server \
    --kube-apiserver-arg service-node-port-range=1-65535

systemctl daemon-reload
systemctl start k3s

 

1.8 K3S修改DNS文件解析

创建自定义 resolv.conf

echo "nameserver 192.168.1.1" | sudo tee /etc/k3s-resolv.conf

修改/etc/rancher/k3s/config.yaml文件

vi /etc/rancher/k3s/config.yaml
kubelet-arg:
- "resolv-conf=/etc/k3s-resolv.conf"

重启k3s进程

sudo systemctl stop k3s
sleep 10
sudo systemctl start k3s
systemctl status k3s

重启所有CoreDNS pod

kubectl get pod -n kube-system -l k8s-app=kube-dns --no-headers | awk '{print $1}' | xargs -I{} kubectl delete pod -n kube-system {}

二、     启动ragflow镜像

2.1 部署ollama配置文件

[root@k3s ragflow]#kubectl apply -f open-webui.yml

查看pod状态

[root@k3s ragflow]#kubectl get pods
NAME                               READY   STATUS RESTARTS       AGE
open-webui-0                       1/1     Running   1 (122m ago)   69d
open-webui-ollama-979dcd68c-sjkrt  1/1     Running   1 (122m ago)   128m
open-webui-pipelines-855c779597    1/1     Running   0              120m

查看svc状态

[root@k3s ragflow]# kubectl get svc

NAME               TYPE        CLUSTER-IP  EXTERNAL-IP PORT(S)     AGE
open-webui         NodePort    10.43.221.218   <none> 80:38080/TCP   69d

open-webui-pipelines ClusterIP 10.43.16.79     <none>  9099/TCP       69d

2.2 部署ragflow配置文件

[root@k3s ragflow]# ls
es.yml  minio.yml  mysql.yml  ragflow.yml  redis.yml
[root@k3s ragflow]# kubectl apply -f .

查看pod状态

[root@k3s ragflow]#kubectl get pods

2.3 查看ragflow状态

[root@k3s ragflow]# kubectl logs -f ragflow-64fd699694-tfvhv
