CLOUDOS3.0前台界面空白，master节点满了，重定向后pod起来前台还是不行

有个rabbit报错，在故障节点上。Error syncing pod, skipping: failed to "StartContainer" for "rabbit1" with CrashLoopBackOff: "Back-off 10s restarting failed cOntainer=rabbit1 pod=rabbit1rc-qdd6n_default(4d4b9b2c-ba2f-11f0-9b26-c2ab20da4d30)"

一、解决 RabbitMQ 容器 CrashLoopBackOff 问题

1. 查看 RabbitMQ 容器日志

   执行命令获取容器启动日志，定位具体报错：
   kubectl logs -f rabbit1rc-qdd6n -c rabbit1 -n default
   重点关注日志中关于数据目录、配置文件、权限或服务依赖的错误（如/var/lib/rabbitmq目录损坏、配置文件语法错误、依赖服务未就绪等）。
2. 检查数据目录完整性

   若日志提示数据目录损坏，需检查持久化卷（PV/PVC）：
   kubectl describe pvc <rabbitmq-pvc-name> -n default
   若数据不可恢复，可尝试删除旧 PVC 并重建（注意：此操作会丢失消息数据，需评估业务影响）。
3. 重建 RabbitMQ 容器

   若确认是容器本身损坏，可删除故障 Pod 强制重建：
   kubectl delete pod rabbit1rc-qdd6n -n default
   若重建后仍崩溃，需检查镜像版本与 CloudOS 的兼容性，确保使用的是cloud-base/rabbitmq-3.6.5:E3106H01-V300R001B01D029-RC3官方适配镜像。

二、检查前端服务依赖的其他组件

1. 查看所有 Pod 状态

   执行命令列出所有 Pod，检查是否有其他服务异常：
   kubectl get pods -n default
   重点关注web、db、cache类 Pod 的Running状态与重启次数。
2. 检查 Web 服务日志

   若前端 Pod 存在，查看其日志是否有与 RabbitMQ 通信失败的报错：
   kubectl logs -f <web-pod-name> -n default
   关键词如RabbitMQ connection failed等。

三、清理残留配置与缓存

1. 清理前端缓存

   进入前端 Pod，删除缓存目录（以 Nginx 为例）：
   kubectl exec -it <web-pod-name> -n default -- rm -rf /var/cache/nginx/*
2. 重启前端服务 Pod

   强制重启前端 Pod，使其重新加载配置：
   kubectl delete pod <web-pod-name> -n default

四、验证系统健康度

1. 访问 CloudOS 前台界面，检查是否仍空白。
2. 执行命令查看系统组件状态：
   kubectl get deployments,statefulsets -n default
   确认所有组件READY状态为1/1。

• 所有相关 Pod 的日志（kubectl logs <pod-name> -n default）
• 节点资源使用情况（kubectl top nodes）
• CloudOS 版本与部署架构详情
