1、下载文件
https://github.com/dotbalo/k8s/tree/master/rabbitmq-cluster
2、创建namespace
kubectl create namespace public-service
如果不使用public-service，需要更改所有yaml文件的public-service为你namespace。
sed -i "s#public-service#YOUR_NAMESPACE#g" *.yaml
3、创建持久化pv
此处采用的是静态PV方式，后端使用的是NFS，为了方便扩展可以使用动态PV较好。
[root@nfs rabbitmq-cluster-1]# cat /etc/exports/k8s/rmq-cluster/rabbitmq-cluster-1/ *(rw,sync,no_subtree_check,no_root_squash)/k8s/rmq-cluster/rabbitmq-cluster-2/ *(rw,sync,no_subtree_check,no_root_squash)/k8s/rmq-cluster/rabbitmq-cluster-3/ *(rw,sync,no_subtree_check,no_root_squash)
[root@k8s-master01 rabbitmq-cluster]# pwd/root/efk/rabbitmq-cluster[root@k8s-master01 rabbitmq-cluster]# lsrabbitmq-cluster-ss.yaml ?rabbitmq-pv.yaml ???rabbitmq-secret.yaml ??????????rabbitmq-service-lb.yamlrabbitmq-configmap.yaml ??rabbitmq-rbac.yaml ?rabbitmq-service-cluster.yaml ?README.md
创建集群
[root@k8s-master01 rabbitmq-cluster]# kubectl apply -f .
4、查看
pods、pv、pvc
[root@k8s-master01 rabbitmq-cluster]# kubectl get pods -n public-serviceNAME ???????????READY ????STATUS ???RESTARTS ??AGErmq-cluster-0 ??1/1 ??????Running ??0 ?????????40mrmq-cluster-1 ??1/1 ??????Running ??0 ?????????39mrmq-cluster-2 ??1/1 ??????Running ??0 ?????????39m
[root@k8s-master01 rabbitmq-cluster]# kubectl get pv -n public-serviceNAME ??????CAPACITY ??ACCESS MODES ??RECLAIM POLICY ??STATUS ???CLAIM ??????????????????????????????????????????STORAGECLASS ???????REASON ???AGEpv-rmq-1 ??4Gi ???????RWX ???????????Recycle ?????????Bound ????public-service/rabbitmq-storage-rmq-cluster-2 ??rmq-storage-class ????????????49mpv-rmq-2 ??4Gi ???????RWX ???????????Recycle ?????????Bound ????public-service/rabbitmq-storage-rmq-cluster-1 ??rmq-storage-class ????????????49mpv-rmq-3 ??4Gi ???????RWX ???????????Recycle ?????????Bound ????public-service/rabbitmq-storage-rmq-cluster-0 ??rmq-storage-class ????????????49m[root@k8s-master01 rabbitmq-cluster]# kubectl get pvc -n public-serviceNAME ????????????????????????????STATUS ???VOLUME ????CAPACITY ??ACCESS MODES ??STORAGECLASS ???????AGErabbitmq-storage-rmq-cluster-0 ??Bound ????pv-rmq-3 ??4Gi ???????RWX ???????????rmq-storage-class ??48mrabbitmq-storage-rmq-cluster-1 ??Bound ????pv-rmq-2 ??4Gi ???????RWX ???????????rmq-storage-class ??48mrabbitmq-storage-rmq-cluster-2 ??Bound ????pv-rmq-1 ??4Gi ???????RWX ???????????rmq-storage-class ??48m[root@k8s-master01 rabbitmq-cluster]#
services，此时使用的NodePort方式，可改为traefik模式
[root@k8s-master01 rabbitmq-cluster]# kubectl get services -n public-serviceNAME ??????????????????TYPE ???????CLUSTER-IP ?????EXTERNAL-IP ??PORT(S) ?????????????????????????AGErmq-cluster ???????????ClusterIP ??None ???????????<none> ???????5672/TCP ????????????????????????1hrmq-cluster-balancer ??NodePort ???10.107.221.85 ??<none> ???????15672:30051/TCP,5672:31892/TCP ??1h
5、访问测试
通过NodePort的端口
账号密码：guest
6、存在问题
上述yaml中有个secret
[root@k8s-master01 rabbitmq-cluster]# cat rabbitmq-secret.yaml kind: SecretapiVersion: v1metadata: ?name: rmq-cluster-secret ?namespace: public-servicestringData: ?cookie: ERLANG_COOKIE ?password: RABBITMQ_PASS ?url: amqp://RABBITMQ_USER:RABBITMQ_PASS@rmq-cluster-balancer ?username: RABBITMQ_USER
定义了username和password，然后在rabbitmq-cluster-ss.yaml引用作为默认账号密码，而且在configmap中也禁用了guest，但是没有生效。此问题待解决。
