K8S部署rocketmq5全過程

 更新時(shí)間：2025年01月02日 09:22:06   作者：萊特昂  
在開發(fā)環(huán)境中部署RocketMQ 5并驗(yàn)證新版本代理特性,遇到一系列問題,包括存儲(chǔ)權(quán)限、主從副本配置和命名空間問題,通過修改配置文件和PV設(shè)置,最終解決了這些問題,成功部署了RocketMQ集群

背景

需要在開發(fā)環(huán)境部署rocketmq5驗(yàn)證新版本proxy相關(guān)的特性，而開發(fā)環(huán)境沒有helm和外網(wǎng)，有k8s的環(huán)境

發(fā)現(xiàn)網(wǎng)上也沒有太多資料，記錄一下操作流程

操作流程

1. helm庫(kù)拉取rocketmq5鏡像

用的是某個(gè)大佬上傳的helm庫(kù)鏡像：

## 添加 helm 倉(cāng)庫(kù)
helm repo add rocketmq-repo https://helm-charts.itboon.top/rocketmq
helm repo update rocketmq-repo
## 查看鏡像
helm search rocketmq
拉取鏡像到本地 兩個(gè)都拉
helm pull itboon/rocketmq
helm pull itboon/rocketmq-cluster
解壓
tar -zxf rocketmq.tgz

2. 單集群?jiǎn)?dòng)測(cè)試

進(jìn)入目錄修改value.yaml文件：

helm啟動(dòng)

helm upgrade --install rocketmq \
  --namespace rocketmq-demo \
  --create-namespace \
  --set broker.persistence.enabled="false" \
  ./rocketmq

3. sc/pv配置

采用的掛載本地的方式設(shè)置：

SC:

vi sc_local.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: local-storage
  annotations:
    openebs.io/cas-type: local
    storageclass.kubernetes.io/is-default-class: "false"
    cas.openebs.io/config: |
      #hostpath type will create a PV by
      # creating a sub-directory under the
      # BASEPATH provided below.
      - name: StorageType
        value: "hostpath"
      #Specify the location (directory) where
      # where PV(volume) data will be saved.
      # A sub-directory with pv-name will be
      # created. When the volume is deleted,
      # the PV sub-directory will be deleted.
      #Default value is /var/openebs/local
      - name: BasePath
        value: "/tmp/storage"
provisioner: openebs.io/local
volumeBindingMode: Immediate
reclaimPolicy: Retain

kubectl apply -f sc_local.yaml

PV（只broker）：

vi local_pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  labels:
    type: local
  name: broker-storage-rocketmq-broker-master-0
  namespace: rocketmq-demo
spec:
  accessModes:
  - ReadWriteOnce
  capacity:
    storage: 100Mi
  hostPath:
    path: /tmp/storage
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: local-storage
  volumeMode: Filesystem

kubectl apply -f local_pv.yaml

4.集群?jiǎn)?dòng)測(cè)試

5.離線安裝

helm導(dǎo)出yaml文件：

helm template rocketmq ./rocketmq-cluster --output-dir ./rocketmq-cluster-yaml

注意，轉(zhuǎn)成yaml文件后，原本用helm設(shè)置的namespace沒了。

執(zhí)行yaml文件驗(yàn)證：

kubectl apply -f rocketmq-cluster-yaml/ --recursive
kubectl delete -f rocketmq-cluster-yaml/ --recursive

yaml導(dǎo)出：

## 安裝傳輸工具
yum install lrzsz
## 打包yaml文件夾
tar czvf folder.tar.gz itboon
sz folder.tar.gz

附錄

最后生成的部署yaml：

踩坑

  • 存儲(chǔ)權(quán)限問題

配置完pv后啟動(dòng)一直報(bào)錯(cuò)。

查日志：

kubectl describe pod rocketmq-broker-master-0 -n rocketmq-demo

結(jié)果：

查應(yīng)用啟動(dòng)日志：

kubectl logs rocketmq-broker-master-0 -n rocketmq-demo

結(jié)果：

具體錯(cuò)誤信息：

03:30:58,822 |-ERROR in org.apache.rocketmq.logging.ch.qos.logback.core.rolling.RollingFileAppender[RocketmqAuthAuditAppender_inner] - Failed to create parent directories for [/home/rocketmq/logs/rocketmqlogs/auth_audit.log]

        at org.apache.rocketmq.broker.BrokerStartup.main(BrokerStartup.java:52)

網(wǎng)上查了下是掛載的本地目錄，pod沒有權(quán)限讀寫。

解決的方式：

1、移出root目錄

由于是root用戶賬號(hào)，k8s啟動(dòng)用的kubectl賬號(hào)，把掛載的目錄移到了/tmp，修改上文PV文件。

2、提前創(chuàng)建PV目錄

在/tmp目錄下創(chuàng)建/tmp/storage，不然啟動(dòng)會(huì)報(bào)PVC沒有該目錄

3、chmod開啟目錄及子目錄的讀寫權(quán)限，需要帶上-R遞歸修改所有子目錄

chmod -R 777 storage
  • 主從副本問題

修改完文件權(quán)限啟動(dòng)后又報(bào)以下錯(cuò)誤：

而且Broker一主一從，一個(gè)正常啟動(dòng)，另一個(gè)報(bào)這個(gè)錯(cuò)誤。網(wǎng)上查了下，正常會(huì)出現(xiàn)在同一個(gè)機(jī)器部署了兩個(gè)Broker的情況下。

但我們的環(huán)境是K8S集群，節(jié)點(diǎn)之間理應(yīng)是隔離的，所以猜想是storage掛載了同一個(gè)目錄的問題，修改PV，兩個(gè)PV掛載的目錄不同，改為storageSlave。再次啟動(dòng)后成功。

  • 命名空間問題

轉(zhuǎn)移到開發(fā)環(huán)境后報(bào)，啟動(dòng)Broker和Namesrver正常，但proxy啟動(dòng)不了，報(bào)：

org.apache.rocketmq.proxy.common.ProxyException: create system broadcast topic DefaultHeartBeatSyncerTopic failed on cluster rocketmq-helm

在本地環(huán)境轉(zhuǎn)完yaml啟動(dòng)時(shí)沒報(bào)過。

網(wǎng)上查了下，如果broker沒正確配置nameserver，也會(huì)報(bào)這個(gè)錯(cuò)誤。懷疑是環(huán)境變了后，某些配置需要根據(jù)環(huán)境修改。把目錄下的配置都仔細(xì)研究了下，尤其涉及broker和proxy的nameserver地址的。

還有個(gè)地方有差異，由于開發(fā)環(huán)境多人共用，有許多的應(yīng)用在跑，而導(dǎo)出的yaml文件會(huì)默認(rèn)在K8S的default namespace啟動(dòng)pod，容易造成混亂和不好管理。所以嘗試在yaml文件中加入了namespace:rocketmq。

最后排查確實(shí)由于這個(gè)導(dǎo)致，在proxy和broker的配置文件中，還有這句讀取nameserver地址的語(yǔ)句：

需要將其中的：

value: rocketmq-nameserver-0.rocketmq-nameserver-headless.default.svc:9876

改為：

value: rocketmq-nameserver-0.rocketmq-nameserver-headless.rocketmq.svc:9876

這個(gè)環(huán)境變量提供了 RocketMQ NameServer 的地址和端口。rocketmq-nameserver-0.rocketmq-nameserver-headless.default.svc 是 NameServer Pod 的 DNS 名稱，9876 是 NameServer 服務(wù)的端口。這個(gè)地址用于客戶端或 Broker 連接到 NameServer，以便進(jìn)行服務(wù)發(fā)現(xiàn)和元數(shù)據(jù)同步。

其中，rocketmq-nameserver-0是當(dāng)前nameserver的name，rocketmq-nameserver-headless對(duì)應(yīng)headless service的name，default對(duì)應(yīng)namespace。所以部署新的K8S命名空間后，需要也把這里的default改為rocketmq的namespace，否則就會(huì)報(bào)找不到無法創(chuàng)建topit的錯(cuò)誤。不過，這里挺奇怪的，broker能正常啟動(dòng)，只有啟動(dòng)proxy的時(shí)候才會(huì)報(bào)這個(gè)錯(cuò)誤，估計(jì)Rocketmq5新版本做了什么修改。

看了別人debug啟動(dòng)源碼，指出是這里的問題：

在BrokerStartup.java閱讀發(fā)現(xiàn)這個(gè)是namesrv的地址，如果不添加的話，會(huì)導(dǎo)致即使你啟動(dòng)了broker，但其實(shí)并不會(huì)在namesrv上有任何注冊(cè)信息。

如果不配置會(huì)發(fā)生什么呢，主要體現(xiàn)在proxy啟動(dòng)的時(shí)候，就一定會(huì)報(bào)錯(cuò)

create system broadcast topic DefaultHeartBeatSyncerTopic failed on cluster DefaultCluster

總結(jié)

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
