emq无法订阅/#问题解决

环境信息

  • EMQ X 版本:4.3.5
  • 操作系统及版本:linux centos7
  • 其他

问题描述

在研究emq共享订阅的时候发现没有办法订阅通配符 /#

在多次卸载重装更换版本无果后,也是没有办法

今天突发奇想,emqx通常目录为

/usr/lib/emqx
/etc/emqx
/var/lib/emqx
/var/log/emqx

我在卸载完emq后 发现/etc/emqx、/var/lib/emqx、/var/log/emqx 目录中还有文件剩余
将剩余文件全部删除后,重装emq,订阅 test/# 发现成功

大概率问题文件为 /etc/emqx/emqx.conf.rpmsave
因为经过比对(其实就是我忘了删了哪些东西)
发现只有这个文件是额外存在的
