使用 gRPC 协议时务端至少升级到5.0版本，并启用 gRPC Proxy 才可兼容。
### 先启动broker
$ nohup sh bin/mqbroker -n localhost:9876 --enable-proxy &
### 验证broker是否启动成功, 比如, broker的ip是192.168.1.2 然后名字是broker-a
$ tail -f ~/logs/rocketmqlogs/proxy.log
The broker[broker-a,192.169.1.2:10911] boot success...修改rocketmq5.1.4/conf/rmq-proxy.json文件
{
"grpcServerPort": 9875,
"rocketMQClusterName": "DefaultCluster"
}
