Mnesia 认证
Mnesia 认证使用 EMQ X 内置 Mnesia 数据库存储客户端 Client ID/Username 与密码,支持通过 HTTP API 管理认证数据。
Mnesia 认证不依赖外部数据源,使用上足够简单轻量。
插件:
emqx_auth_mnesia
哈希方法
Mnesia 认证默认使用 sha256 进行密码哈希加密,可在 etc/plugins/emqx_auth_mnesia.conf
中更改:
# etc/plugins/emqx_auth_mnesia.conf
## Value: plain | md5 | sha | sha256
auth.mnesia.password_hash = sha256
配置哈希方法后,新增的预设认证数据与通过 HTTP API 添加的认证数据将以哈希密文存储在 EMQ X 内置数据库中。
预设认证数据
可以通过配置文件预设认证数据,编辑配置文件:etc/plugins/emqx_auth_mnesia.conf
预设认证数据格式兼容 emqx_auth_clientid
与 emqx_auth_username
插件的配置格式
# etc/plugins/emqx_auth_mnesia.conf
## clientid 认证数据
auth.client.1.clientid = admin_client
auth.client.1.password = public
## username 认证数据
auth.user.2.username = admin
auth.user.2.password = public
插件启动时将读取预设认证数据并加载到 EMQ X 内置数据库中,节点上的认证数据会在此阶段同步至集群中。
预设认证数据在配置文件中使用了明文密码,出于安全性与可维护性考虑应当避免使用该功能。
