环境

  • EMQX 版本：5.1.6
  • 操作系统版本：

重现此问题的步骤

  1. 在 emqx.conf authentication块中添加配置
    {
    type = redis
    enable = true

     redis_type = single 
 
 pool_size = 8
 password_hash_algorithm {name = "plain", salt_position = "disable"}
 
 cmd = "HMGET DH:WEB_MQTT:${username} password_hash"
 database = 0
 password = password
 server = "127.0.0.1:6379"

}
启动报错

TIP： 如果是复杂的配置不好配置。但是想固化在 emqx.conf中启动
可以在 dashbaord 配置好后
把配置从data/configs/cluster.hocon里面copy 出来。
最新版本，还可以使用：

 ./bin/emqx ctl conf
conf reload --replace|--merge              # reload etc/emqx.conf on local node
                                           # The new configuration values will be overlaid on the existing values by default.
                                           # use the --replace flag to replace existing values with the new ones instead.
----------------------------------         # ------------
conf show_keys                             # print all the currently used configuration keys.
conf show [<key>]                          # Print in-use configs (including default values) under the given key.
                                           # Print ALL keys if key is not provided
conf load --replace|--merge <path>         # Load a HOCON format config file.
                                           # The new configuration values will be overlaid on the existing values by default.
                                           # use the --replace flag to replace existing values with the new ones instead.
                                           # The current node will initiate a cluster wide config change
                                           # transaction to sync the changes to other nodes in the cluster.
                                           # NOTE: do not make runtime config changes during rolling upgrade.
----------------------------------         # ------------

conf cluster_sync inspect <ID>             # Inspect detailed information of the config change transaction at the given commit ID
conf cluster_sync skip [node]              # Increment the (currently failing) commit on the given node.
                                           # WARNING: This results in inconsistent configs among the clustered nodes.
conf cluster_sync fast_forward [node] <ID> # Fast-forward config change to the given commit ID on the given node.
                                           # WARNING: This results in inconsistent configs among the clustered nodes.

来操作配置。
