MQTT broker
Broker 幾乎都是 Erlang 的天下
後續考量 MySQL 身份認證、SSL、平台支援、ACL 訂閱限制，最後選擇 EMQ X
--
EMQ X
不得不說，大陸的軟體就是好用，設想的較為周全，文件也齊全，平台支援性也完整

VerneMQ
CentOS 7
下載安裝後不要傻傻的按照官方的說法直接啟動服務，那是不會成功的，還要先設定設定檔才行

Ubuntu 20 - Docker
使用 dpkg 安裝 deb ，出現 libss 版本不符錯誤，目前找不到解決方法，改採 Docker 方式使用

# docker run -p 1883:1883 -p 8888:8888 -e "DOCKER_VERNEMQ_ACCEPT_EULA=yes" -e "DOCKER_VERNEMQ_ALLOW_ANONYMOUS=on" --name vernemq1 -d vernemq/vernemq |
使用 netstat 查詢轉址無法判斷，直接測試使用即可
