【RocketMQ】RocketMQ 5.1.0版本Proxy集群模式部署实践

为了支持长远的云原生发展，RocketMQ引入了一个全新的模块：Proxy，官方对RocketMQ客户端提供了独立的开源项目：https://github.com/apache/rocketmq-clients，如果要使用这个新的客户端，必须要使用Proxy作为endpoint。

Proxy有两种搭建方式：

• LOCAL：本地模式，顾名思义，通过追加参数，在broker本地启动
• CLUSTER：集群模式，作为独立的集群启动，搭建完nameserver和broker后，独立部署

本地模式更适合非正式的场景，如调试、开发，线上环境还是推荐集群模式，本文基于集群模式进行部署验证。

启动proxy使用mqproxy命令：

[root@XXGL-T-TJSYZ-REDIS-01 bin]# ./mqproxy -help
usage: mqproxy [-bc ] [-h] [-n ] [-pc ] [-pm ]
 -bc,--brokerConfigPath    Broker config file path for local mode
 -h,--help                      Print help
 -n,--namesrvAddr          Name server address list, eg: '192.168.0.1:9876;192.168.0.2:9876'
 -pc,--proxyConfigPath     Proxy config file path
 -pm,--proxyMode           Proxy run in local or cluster mode
[root@XXGL-T-TJSYZ-REDIS-01 bin]# 

• -bc：使用本地模式时，指定broker的配置文件路径
• -h：输出帮助信息；
• -n：nameserver路径，也可以通过在配置文件中配置namesrvAddr指定；
• -pc：proxy配置文件路径；
• -pm：代理模式：LOCAL / CLUSTER，默认为CLUSTER（集群模式）

需要编辑的文件有：

• bin/runserver.sh：修改GC日志目录和JVM参数；（非必须）
• conf/rmq-proxy.json：
  主要是设置集群名、自定义端口

  "rocketMQClusterName": "littleCat",
  "remotingListenPort":28080,
  "grpcServerPort":28081
}

完整参数见源码：org.apache.rocketmq.proxy.config.ProxyConfig

启动脚本：

#!/bin/bash
. /etc/profile

nohup sh /neworiental/rocketmq-5.1.0/rocketmq-proxy/bin/mqproxy -n '172.24.30.192:19876;172.24.30.193:19876;172.24.30.194:19876' -pc /neworiental/rocketmq-5.1.0/rocketmq-proxy/conf/rmq-proxy.json >/dev/null 2>&1 &
echo "deploying rocketmq-proxy..."

停止脚本：

#!/bin/bash
. /etc/profile

PID=`ps -ef | grep '/neworiental/rocketmq-5.1.0/rocketmq-proxy' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing rocketmq-proxy : $PID"
  kill $PID
fi

启动成功

客户端测试：

pom依赖：

        <dependency>
            <groupId>org.apache.rocketmqgroupId>
            <artifactId>rocketmq-client-javaartifactId>

以上，搭建成功，消息生产消费成功~

遇到的问题：

找到rmq.proxy,logback.xml，批量修改对应的路径：

将${brokerLogDir}批量替换成自定义的路径即可。

dashboard目前还不能采集到客户端的信息：
