背景

RacketMQ 5.X 的发布，向云原生迈出了一大步。从官方的文档中，我们可以看到其中最大的一块变化是新增了 Proxy 模块，新旧版本架构对比如下：

  • RocketMQ 4.X 架构

    rocketmq4.x-arch.png

  • RocketMQ 5.X 架构

    rocketmq5.x-arch.png

在 RocketMQ4.X 的时候，深入使用过 RocketMQ 的人很多都可能遇到一个问题，RocketMQ 在复杂网络下是有缺陷的，比如说网上就有很多人问 RocketMQ 如何同时对内网和外网提供服务。得到的答案可能是让你修改brokerIP1、brokerIP2，brokerIP1 指向公网IP，brokerIP2 指向内网IP。但是这样并不能解决问题，因为 NameServer 始终会向客户端返回 brokerIP1 的地址，并不是真正解决了内外网的问题。

而 Proxy 模块的加入，客户端不再需要知道 Broker 的地址了，而是通过 Proxy 做一层中转，因此可以彻底解决复杂网络接入的问题。Proxy 使用全新的 gRPC 协议接受客户端的请求，同时也兼容 4.X 的 Remoting 协议，使得 RocketMQ 可以灵活地接入不同版本的客户端请求。

默认情况下，Proxy 的 8080 端口提供 Remoting 协议的接入，8081 端口提供 gRPC 协议的接入。Proxy 有一个参数 remotingAccessAddr 控制向 Remoting 协议客户端返回的访问地址。 你甚至可以这样做：

  • 搭建一套 Proxy，设置 remotingAccessAddr 为内网地址，对内网提供服务
  • 搭建另一套 Proxy，设置 remotingAccessAddr 为外网地址，对外网提供服务
  • 还可以不用 Proxy，客户端通过 Name Server 拿到 Broker 的地址，和 4.X 的架构基本一样
在编写这篇文章的时刻，RocketMQ 刚刚发布了 5.1.0 版本，但是经过我验证测试，proxy 还没做好旧版本协议的兼容，让我们一起期待下个版本的发布吧。

部署

RocketMQ 5.X 已经拥抱云原生，在 Kubernetes 上部署起来已经不再是难事。在我写这篇文章的时候，官方还没发布 5.X 版本的容器镜像，因此我是自己制作的镜像。

yaml

注意：此yaml部署的是单实例，且没有做持久存储，仅供测试用。

yaml 是使用 rocketmq-docker/rocketmq-k8s-helm at master · apache/rocketmq-docker · GitHub 生成的，并做了一点修改。其中 remotingAccessAddr 参数自行修改。

容器镜像是使用 rocketmq-docker/image-build at master · apache/rocketmq-docker · GitHub 生成的，对脚本做了一点修改。

踩坑

在部署使用的过程中，遇到了不少的问题，这里给大家分享一下，提供参考。

alpine 为基础镜像，proxy 运行不了

使用默认的 Dockerfile-alpine 制作的镜像，运行 proxy 会报错：

省略很多错误信息...
find an unexpect err.java.lang.RuntimeException: grpc tls set failed: Could not find TLS ALPN provider; no working netty-tcnative, Conscrypt, or Jetty NPN/ALPN available

我修改了 Dockerfile-alpine，用 alpine3.17.0，安装 openjdk 8.345.01-r3，运行依然报错：

#

最后，用 centos 作为基础镜像，就正常运行了。

./build-image.sh 5.1.0 centos

RocketMQ 5.1.0 才支持 remoting 协议

我刚开始测试的时候，最新的 release 版本是 5.0.0。这个版本不支持 remoting 协议，而且官方又没有说明，这个比较坑，我看了源码才发现的。

后来等官方发布 5.1.0 后就支持 remoting 协议了。但是没有兼容 4.X 的客户端，还需要再等等。

默认制作的镜像不支持自定义启动参数，比如 -Xmx -Xms 等

官方发布的 release bin 包，启动脚本不支持自定义启动参数，比如 -Xmx -Xms 等。我在 rocketmq-docker/image-build at master · apache/rocketmq-docker · GitHub 的基础上修改了 scripts/runbroker-customize.sh 和 scripts/runserver-customize.sh，使其根据 resources.limits.memory 的设置自动配置 -Xmx -Xms 等参数。修改后的内容如下：

  • runbroker-customize.sh
