解决方案

要解决此问题,请检查是否由于 Mnesia 表数据写入问题,部分或所有 RabbitMQ Pod 处于 CrashLoopBackOff 状态。

如果所有 Pod 都在运行,请执行以下步骤:

  1. 删除 RabbitMQ 中的用户:

    kubectl -n rabbitmq exec rabbitmq-server-0 -c rabbitmq -- rabbitmqctl  list_users -s --formatter json | jq '.[]|.user' | grep -v default_user | xargs -I{} kubectl -n rabbitmq exec rabbitmq-server-0 -c rabbitmq -- rabbitmqctl delete_user {}kubectl -n rabbitmq exec rabbitmq-server-0 -c rabbitmq -- rabbitmqctl  list_users -s --formatter json | jq '.[]|.user' | grep -v default_user | xargs -I{} kubectl -n rabbitmq exec rabbitmq-server-0 -c rabbitmq -- rabbitmqctl delete_user {}
  2. 删除 UiPath 命名空间中的 RabbitMQ 应用程序密码:

    kubectl -n uipath get secret --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | grep -i rabbitmq-secret | xargs -I{} kubectl -n uipath delete secret {}kubectl -n uipath get secret --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | grep -i rabbitmq-secret | xargs -I{} kubectl -n uipath delete secret {}
  3. 删除 RabbitMQ 命名空间中的 RabbitMQ 应用程序密码:

    kubectl -n rabbitmq get secret --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | grep -i rabbitmq-secret | xargs -I{} kubectl -n rabbitmq delete secret {}kubectl -n rabbitmq get secret --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | grep -i rabbitmq-secret | xargs -I{} kubectl -n rabbitmq delete secret {}
  4. 通过 ArgoCD 同步 sfcore 应用程序并等待同步完成:


  5. 对 UiPath 命名空间中的所有应用程序执行首次重新启动:

    kubectl -n uipath rollout restart deploykubectl -n uipath rollout restart deploy

如果某些 Pod 处于 CrashLoopBackOff 状态,请执行以下步骤:

  1. 确定哪些 RabbitMQ Pod 卡在 CrashLoopBackOff 状态,并检查 RabbitMQ CrashLoopBackOff Pod 日志:
    kubectl -n rabbitmq get pods
    kubectl -n rabbitmq logs <CrashLoopBackOff-Pod-Name>kubectl -n rabbitmq get pods
    kubectl -n rabbitmq logs <CrashLoopBackOff-Pod-Name>
  2. 检查前面命令的输出。如果问题与 Mnesia 表数据写入有关,您应该会看到类似于以下内容的错误消息:

    Mnesia('rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq'): ** ERROR ** (could not write core file: eacces)
     ** FATAL ** Failed to merge schema: Bad cookie in table definition rabbit_user_permission: 'rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq' = {cstruct,rabbit_user_permission,set,[],['rabbit@rabbitmq-server-2.rabbitmq-nodes.rabbitmq','rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq','rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'],[],[],0,read_write,false,[],[],false,user_permission,[user_vhost,permission],[],[],[],{{1667351034020261908,-576460752303416575,1},'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'},{{4,0},{'rabbit@rabbitmq-server-2.rabbitmq-nodes.rabbitmq',{1667,351040,418694}}}}, 'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq' = {cstruct,rabbit_user_permission,set,[],['rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'],[],[],0,read_write,false,[],[],false,user_permission,[user_vhost,permission],[],[],[],{{1667372429216834387,-576460752303417087,1},'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'},{{2,0},[]}}Mnesia('rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq'): ** ERROR ** (could not write core file: eacces)
     ** FATAL ** Failed to merge schema: Bad cookie in table definition rabbit_user_permission: 'rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq' = {cstruct,rabbit_user_permission,set,[],['rabbit@rabbitmq-server-2.rabbitmq-nodes.rabbitmq','rabbit@rabbitmq-server-0.rabbitmq-nodes.rabbitmq','rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'],[],[],0,read_write,false,[],[],false,user_permission,[user_vhost,permission],[],[],[],{{1667351034020261908,-576460752303416575,1},'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'},{{4,0},{'rabbit@rabbitmq-server-2.rabbitmq-nodes.rabbitmq',{1667,351040,418694}}}}, 'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq' = {cstruct,rabbit_user_permission,set,[],['rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'],[],[],0,read_write,false,[],[],false,user_permission,[user_vhost,permission],[],[],[],{{1667372429216834387,-576460752303417087,1},'rabbit@rabbitmq-server-1.rabbitmq-nodes.rabbitmq'},{{2,0},[]}}
  3. 要解决此问题,请执行以下步骤:

    1. 查找 RabbitMQ 副本的数量:

      rabbitmqReplicas=$(kubectl -n rabbitmq get rabbitmqcluster rabbitmq -o json | jq -r '.spec.replicas')

    2. 缩减 RabbitMQ 副本:

      kubectl -n rabbitmq patch rabbitmqcluster rabbitmq -p "{\"spec\":{\"replicas\": 0}}" --type=merge

      kubectl -n rabbitmq scale sts rabbitmq-server --replicas=0

    3. 等待所有 RabbitMQ Pod 终止:

      kubectl -n rabbitmq get pod

    4. 查找并删除卡在 CrashLoopBackOff 状态的 RabbitMQ Pod 的 PVC:

      kubectl -n rabbitmq get pvc

      kubectl -n rabbitmq delete pvc <crashloopbackupoff_pod_pvc_name>

    5. 扩展 RabbitMQ 副本:

      kubectl -n rabbitmq patch rabbitmqcluster rabbitmq -p "{\"spec\":{\"replicas\": $rabbitmqReplicas}}" --type=merge

    6. 检查所有 RabbitMQ Pod 是否运行状况良好:

      kubectl -n rabbitmq get pod
