1、下载文件
https://github.com/dotbalo/k8s/
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 None5672/TCP 1hrmq-cluster-balancer NodePort 10.107.221.85 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。
