我的操作系统是i.MX6Q上的Yocto Rocko。
我使用docker v17.06加载了三个greengrass镜像版本1.7.1、1.8.1和1.9.2。
我按照每个软件包中的README.md进行了逐步设置和安装。
所有图像都无法连接我创建的AWS greengrass组。
以下是有关错误的日志，我认为原因是MQTT设置有问题。我在mosquitto.conf上搜索了有关greengrass的信息，但找不到任何解决方案。
这是我的蚊子信息。
root@imx6qsabresd:/etc/mosquitto# mosquitto -h
mosquitto version 1.4.14 (build date 2019-06-26 15:24:46+0800)
mosquitto is an MQTT v3.1.1/v3.1 broker.
谁能告诉我如何为greengrass设置mosquitto.conf？
还是根本原因是另一个原因？

最佳答案
您可以在通常可用的端口443上使用AWS MQTT。要使用此端口，http header 值“应用程序协议(protocol)名称”需要设置为“x-amzn-mqtt-ca”。请在这里阅读更多内容:

关于docker - 无法连接AWS Greengrass，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/56832111/
