本次部署为基于k8s部署rocketmq两主两从集群,本次服务器为:

在这里插入图片描述
1.设置nfs存储

(1) yum下载nfs,rpcbind,四台机器上都执行

yum install -y nfs-utils rpcbind

(2) 在176上执行,设置/data为nfs共享目录，在exports文件中新增下列内容

vi /etc/exports

/data/ *(rw,sync,no_root_squash)在这里插入图片描述
(3) 176节点上执行,创建数据存储路径

mkdir -p /data/rocketmq
在这里插入图片描述
(4) 176节点上执行,设置数据存储路径文件权限

chmod -R 755 /data/rocketmq

(5) 176节点上执行,使新增的nfs共享目录生效

exportfs -arv

(6) 四台机器上都执行,启动rpcbind并设置开机自启

systemctl enable rpcbind && systemctl start rpcbind

(7) 四台机器上都执行,启动nfs并设置开机自启

systemctl enable nfs && systemctl start nfs

2.创建nfs相关pod.

176上以root用户操作,当前操作路径为/root/rocketmq,之后操作都在次路径下.

(2) 创建storageclass

vim rocketmq-nfs-class.yaml


kind: StorageClass

metadata:

  namespace: wiseco

provisioner: rocketmq/nfs

reclaimPolicy: Retain

(3) 创建rocketmq-nfs-class.yaml

          imagePullPolicy: IfNotPresent

          volumeMounts:

            - name: nfs-client-root

              mountPath:  /persistentvolumes

          env:

          nfs:

            server: 192.168.212.176

            path: /data/rocketmq

注:192.168.212.176更改为自己的ip

(4) 使上面三个配置文件生效

① kubectl apply -f nfs-raabc.yaml (kubectl apply -f 可以理解为使配置文件生效,这里就是使nfs-raabc.yaml文件生效)

② kubectl apply -f rocketmq-nfs-class.yaml

③ kubectl apply -f rocketmq-nfs.yml

(5) 查看rocketmq的nfs是否创建成功

kubectl get pods -n wiseco|grep nfs
在这里插入图片描述
3.制作镜像

镜像已制作好,把这三个镜像包包分别上传到176,177,178,179四台机器上并使用docker load -i 命令转为镜像即可.镜像制作看查看参考文档.

4.准备配置文件,创建configmap

进入config目录,需要自己创建并进入,编辑四个broker配置文件
(1) vim broker-a.properties

brokerClusterName=rocketmq-cluster

brokerName=broker-a

brokerIP1=192.168.212.178

brokerId=0

namesrvAddr=192.168.212.179:30915

mapedFileSizeCommitLog=1073741824

mapedFileSizeConsumeQueue=300000

diskMaxUsedSpaceRatio=88

storePathRootDir=/data/rocketmq/store

maxMessageSize=65536

brokerRole=MASTER

(2) vim broker-a-s.properties

brokerClusterName=rocketmq-cluster

brokerName=broker-a

brokerIP1=192.168.212.179

brokerId=1

namesrvAddr=192.168.212.179:30915

mapedFileSizeCommitLog=1073741824

mapedFileSizeConsumeQueue=300000

diskMaxUsedSpaceRatio=88

storePathRootDir=/data/rocketmq/store

maxMessageSize=65536

brokerRole=SLAVE

flushDiskType=SYNC_FLUSH

(3) vim broker-b.properties

brokerClusterName=rocketmq-cluster

brokerName=broker-b

brokerIP1=192.168.212.179

brokerId=0

namesrvAddr=192.168.212.179:30915

defaultTopicQueueNums=4

mapedFileSizeConsumeQueue=300000

diskMaxUsedSpaceRatio=88

storePathRootDir=/data/rocketmq/store

maxMessageSize=65536

brokerRole=MASTER

flushDiskType=SYNC_FLUSH

(4) vim broker-b-s.properties

brokerClusterName=rocketmq-cluster

brokerName=broker-b

brokerIP1=192.168.212.178

brokerId=1

namesrvAddr=192.168.212.179:30915

mapedFileSizeConsumeQueue=300000

diskMaxUsedSpaceRatio=88

storePathRootDir=/data/rocketmq/store

maxMessageSize=65536

brokerRole=SLAVE

flushDiskType=SYNC_FLUSH

(5) 依据上面rocketmq的4个配置文件创建configmap存储卷

kubectl create configmap rocketmq-config --from-file=broker-a.properties --from-file=broker-b.properties --from-file=broker-a-s.properties --from-file=broker-b-s.properties -n wiseco (根据四个broker创建configmap)
在这里插入图片描述
(6) 查询配置文件是否生成

kubectl get cm -n wiseco|grep rocketmq

5.部署rocketmq容器实例

在rocketmq目录下新建deploy目录并进入

(7) 使上述配置文件生效,在deploy目录下执行

kubectl apply -f .
在这里插入图片描述
(8) 查看rocketmq 的pod情况

kubectl get pod -n wiseco (STATUS皆为RUNNING则成功启动)
在这里插入图片描述
(9) 查看rocketmq的service服务是否全部启动

kubectl get svc -n wiseco (如图,总共6个服务全部启动)
在这里插入图片描述
(10) 查看控制台状态

访问:192.168.212.176:30916 ,即可进入控制台,将ip换成自己的ip:30916可访问自己部署的控制台.进入后点击cluster,能够看到四个broker则控制台状态正常.
在这里插入图片描述
(11) 问题解决

如果控制台不显示各个broker,报错如下:
在这里插入图片描述
点击OPS,之后点击下方按钮,关闭之后点击update,看到success之后再次点击Cluster,显示正常.
在这里插入图片描述
至此部署完成.
