Deepstream使用Rabbitmq 和kafka发送消息(天坑)unable to connect to broker library

连接服务器失败，要么是是本地参数没设对, 要么服务器没开！

使用Kafka发送消息好搞，按照 /opt/nvidia/deepstream/deepstream-6.2/sources/libs/kafka_protocol_adaptor/README 一步一步来就行了，前提是要搞kafka 环境搭建开启，这个在README 里面是没有提到的。
kafka 环境搭建

1. 安装jdk

$ apt-get update && apt-get install openjdk-8-jdk

2. 安装kafka

https://www.apache.org/dyn/closer.cgi?path=/kafka/3.3.1/kafka_2.13-3.3.1.tgz
$ tar -xzf kafka_2.13-3.3.1.tgz
$ cd kafka_2.13-3.3.1

3 开启两个服务器

3.1 Start the ZooKeeper service
$ ./bin/zookeeper-server-start.sh config/zookeeper.properties
3.2 start a new teminal, Start the Kafka broker service
$ ./bin/kafka-server-start.sh config/server.properties

4. 测试kafka

4.1 创建主题，这条命令只用执行一次，执行完会自己退出。
$ ./bin/kafka-topics.sh --create --topic mytopic --bootstrap-server localhost:9092

4.2 开启消费者
$ ./bin/kafka-console-consumer.sh --topic mytopic --from-beginning --bootstrap-server localhost:9092

5. Deepstream 推消息

$ cd /opt/nvidia/deepstream/deepstream-6.2/sources/apps/sample_apps/deepstream-test4
配置好
dstest4_config.yml

msgbroker:
  proto-lib: /opt/nvidia/deepstream/deepstream-6.2//lib/libnvds_kafka_proto.so
  conn-str: localhost;9092
  topic: mytopic

$ ./deepstream-test4-app dstest4_config.yml
即可

下面才是今天重点，Rabbitmq ！

1. 安装Rabbitmq 开启服务

按照 /opt/nvidia/deepstream/deepstream-6.2/sources/libs/amqp_protocol_adaptor/README
$sudo service rabbitmq-server status
Running 即可
make 后测试
./test_amqp_proto_async
./test_amqp_proto_sync
都没有问题，下面创建exchange， Queue， Bind Queue to exchange

2. Deepstream 推消息

使用
$ ./deepstream-test4-app -i …/…/…/…/samples/streams/sample_720p.h264 -p /opt/nvidia/deepstream/deepstream-6.2/lib/libnvds_amqp_proto.so --conn-str=“localhost;5672;guest;guest” --topic=topicname -s 0
没有问题，但是
如果按照官方文档kafaka模板更改
dstest4_config.yml

msgbroker:
  proto-lib: /opt/nvidia/deepstream/deepstream-6.2/lib/libnvds_amqp_proto.so
  conn-str: localhost;5672
  topic: topicname
  sync: 0

$ ./deepstream-test4-app dstest4_config.yml
问题来了，报错：

ERROR from element nvmsg-broker: Could not configure supporting library.
Error details: /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvmsgbroker/gstnvmsgbroker.cpp(401): legacy_gst_nvmsgbroker_start (): /GstPipeline:dstest4-pipeline/GstNvMsgBroker:nvmsg-broker:
unable to connect to broker library

再次更改dstest4_config.yml，添加用户名密码

msgbroker:
  proto-lib: /opt/nvidia/deepstream/deepstream-6.2/lib/libnvds_amqp_proto.so
  #conn-str: localhost;5672
  conn-str: localhost;5672;guest;guest
  topic: topicname
  sync: 0

$ ./deepstream-test4-app dstest4_config.yml
跑起来了！
