环境
- EMQX 版本：V5.0.8 Docker部署单点节
- 操作系统版本：CentOS7.9
重现此问题的步骤
安装步骤：
创建挂载目录
mkdir -p /data/emqx/{bin,etc,lib,data,log}
运行镜像
docker run -d --name emqx
-p 1883:1883
-p 8083:8083
-p 8084:8084
-p 8883:8883
-p 18083:18083
–restart=always
emqx/emqx:5.0.8
将临时EMQX容器的文件拷贝到服务器
docker cp emqx:/opt/emqx/bin /data/emqx
docker cp emqx:/opt/emqx/etc /data/emqx
docker cp emqx:/opt/emqx/lib /data/emqx
docker cp emqx:/opt/emqx/log /data/emqx
docker cp emqx:/opt/emqx/data /data/emqx
修改挂载目录权限
chown -R 1000:1000 /data/emqx/
chmod -R 755 /data/emqx/
删除临时emqx容器
docker rm -f emqx
重新启动一个EMQX
docker run -d --name emqx5.0.8
-p 5883:1883
-p 5083:8083
-p 5084:8084
-p 5123:8883
-p 58083:18083
-v /data/emqx/bin:/opt/emqx/bin
-v /data/emqx/etc:/opt/emqx/etc
-v /data/emqx/lib:/opt/emqx/lib
-v /data/emqx/data:/opt/emqx/data
-v /data/emqx/log:/opt/emqx/log
-v /etc/localtime:/etc/localtime
–restart=always
emqx/emqx:5.0.8
以上是我用Docker部署的详细步骤
- 登录WEB管理页面，修改默认的密码
- 在管理页面创建认证，选择基于密码认证，再添加用户添加用户；
- 关键问题就是，这个EMQX在运行一段时间之后（这个时间多长没有统计 ，也不知道有不有规律），程序就连接不上，再次登录EMQX的管理页面，以前修改的密码登录不了，只能用程序默认的账号admin与密码public登录进去，进去之后，里面创建的密码认证与添加的用户也没有了，需要再重新创建认证与添加用户
