卸载EMQX后重新安装后打开dashboard规则页面报500错误

环境信息

  • EMQ X 版本:4.2.13
  • 操作系统及版本:CentOS7.8
  • 其他

问题描述

按照官方文档操作:
刚开始是安装的最新版的emqx
执行命令:

sudo yum install emqx

后面发现最新版的MQTT连接速度有点慢,所以卸载了,执行命令:

sudo yum remove emqx

然后重新安装4.2.13版本:

sudo yum install emqx-4.2.13

打开 dashboard 发现卸载前创建的规则和资源都还在。。。
然后打开规则页面发现报500错误了。
我尝试又卸载4.2.13版本然后删除 /etc/emqx 文件夹再重新安装4.2.13版本,发现还是存在这个问题。
使用 emqx console 命令启动发现存在报错:

请问是否是没有完全卸载干净导致的?但我是按照官方文档的卸载命令操作的。。
这个问题请问要如何处理呢?

已解决,还需要删除配置和数据文件。
rm -rf /var/lib/emqx
rm -rf /etc/emqx
