k8s部署rabbitmq集群的方式

更新時(shí)間：2024年03月11日 09:52:24 作者：Apex?Predator

本次部署方式為setafulset的方式部署rabbitmq集群，使用svc的無(wú)頭服務(wù)，本次涉及使用到的服務(wù)有setafulset、secret、configmap、service、pv、pvc、sa，在rabbitmq的官網(wǎng)中使用的是operator的方式，感興趣的朋友一起看看吧

一、前言

本次部署方式為setafulset的方式部署rabbitmq集群，使用svc的無(wú)頭服務(wù)，本次涉及使用到的服務(wù)有setafulset、secret、configmap、service、pv、pvc、sa，在rabbitmq的官網(wǎng)中使用的是operator的方式

operator方式參考:RabbitMQ Cluster Kubernetes Operator Quickstart | RabbitMQ

二、部署

創(chuàng)建rabbitmq yaml文件存放目錄

mkdir /opt/rabbitmq && cd /opt/rabbitmq

編輯secret配置

vi secret.yaml

kind: Secret
apiVersion: v1
metadata:
  name: rabbitmq
  namespace: rabbitmq
type: Opaque
stringData:
  rabbitDefaulUser: admin       #設(shè)置rabbitmq集群的用戶名
  rabbitDefaultPass: admin      #設(shè)置rabbitmq集群的密碼
  erlang.cookie: ERLANG_COOKIE    #集群需要用到的cookie值，每個(gè)節(jié)點(diǎn)都需要保持一致

編輯configmap配置

vi configmap.yaml

kind: ConfigMap
apiVersion: v1
metadata:
  name: rabbitmq-config
  namespace: rabbitmq
data:
   enabled_plugins: |
      [rabbitmq_management,rabbitmq_peer_discovery_k8s].
   rabbitmq.conf: |
      cluster_formation.peer_discovery_backend  = rabbit_peer_discovery_k8s
      cluster_formation.k8s.host = kubernetes.default.svc.cluster.local
      cluster_formation.k8s.address_type = hostname
      cluster_formation.k8s.hostname_suffix = .rabbitmq-headless.rabbitmq.svc.cluster.local
      cluster_formation.node_cleanup.interval = 30
      cluster_formation.node_cleanup.only_log_warning = true
      cluster_partition_handling = autoheal
      queue_master_locator=min-masters
      cluster_formation.randomized_startup_delay_range.max = 2
      vm_memory_high_watermark.absolute = 1GB
      disk_free_limit.absolute = 2GB
      loopback_users.guest = false

編輯rbac配置

vi rbac.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: rabbitmq
  namespace: rabbitmq
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: endpoint-reader
  namespace: rabbitmq
rules:
- apiGroups: [""]
  resources: ["endpoints"]
  verbs: ["get"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: endpoint-reader
  namespace: rabbitmq
subjects:
- kind: ServiceAccount
  name: rabbitmq
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: endpoint-reader

編輯service配置

vi service.yaml

kind: Service
apiVersion: v1
metadata:
  name: rabbitmq-headless       #該service服務(wù)為提供無(wú)頭服務(wù)
  namespace: rabbitmq
spec:
  clusterIP: None
  publishNotReadyAddresses: true
  ports:
   - name: amqp
     port: 5672
   - name: http
     port: 15672
  selector:
    app: rabbitmq

vi service-nodeport.yaml

kind: Service
apiVersion: v1
metadata:
  namespace: rabbitmq
  name: rabbitmq-service
spec:
  ports:
  - name: http
    protocol: TCP
    port: 15672
    nodePort: 30015  #管理web界面
  - name: amqp
    protocol: TCP
    port: 5672
    targetPort: 5672
    nodePort: 30016
  selector:
    app: rabbitmq
  type: NodePort

編輯pv配置(使用該nfs路徑時(shí)一定要配置一定的寫入權(quán)限，不然啟動(dòng)rabbitmq服務(wù)時(shí)會(huì)出現(xiàn)沒有寫入權(quán)限而報(bào)錯(cuò))

vi pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: rabbitmq-pv01
spec:
  storageClassName: rabbitmq-pv    #定義了存儲(chǔ)類型
  capacity:
    storage: 30Gi

  persistentVolumeReclaimPolicy: Retain
  nfs:

    server: 10.1.13.99

編輯setafulset配置

      accessModes: [ "ReadWriteMany" ]
      resources:
        requests:
          storage: 30Gi

創(chuàng)建命名空間

kubectl create namespace rabbitmq

創(chuàng)建各yaml服務(wù)

kubectl create -f secret.yaml
kubectl create -f configmap.yaml
kubectl create -f pv.yaml
kubectl create -f service.yaml
kubectl create -f service-nodeport.yaml
kubectl create -f setafulset.yaml

查看集群狀態(tài)

kubectl exec -it rabbitmq-0 -n rabbitmq -- rabbitmqctl cluster_status

可以看到rabbitmq集群正常運(yùn)行，至此rabbitmq集群部署完成。
