    Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. The default epmd port is 4369, but this can be changed using the ERL_EPMD_PORT environment variable. For further details see the Erlang epmd manpage. Once a distributed Erlang node address has been resolved via epmd, other nodes will attempt to communicate

    如何使用一门新的语言

    要想在你本地远程连接生产环境的 node,你需要知道其在 epmd 下注册的端口。 这样的需求我一般都用 ssh port forwarding 来完成: PORT_PROD=$(shell ssh prod-cms-service "epmd -names" | grep cms_service epmd -names 显示本机在 epmd 注册的服务的端口号。为了找到生产环境下当前运行的服务的端口号,我们需要 ssh 上去运行这条命令。 服务在 epmd 注册的端口是动态的,不像 epmd 自身的端口 4369 是固定(或者可配置)的 ,因此你无法为防火墙单独开放这个端口。

  • 解密RabbitMQ:你所不知道的端口及其重要性

    第三部分:Erlang Port Mapper Daemon(epmd)端口(4369) Erlang Port Mapper Daemon(epmd)是Erlang编程语言中的一个重要组件,用于节点之间的通信 下面是有关epmd和其监听的端口4369的信息: epmd的作用,用于节点之间的通信: epmd(Erlang Port Mapper Daemon)是一个独立的守护进程,它在Erlang分布式系统中扮演着关键的角色 当Erlang节点启动时,它需要在分布式系统中找到其他节点以便进行通信,epmd负责维护这些节点的注册信息。 每个节点在启动时会向epmd注册,以及在需要与其他节点通信时,它会查询epmd获取目标节点的端口信息,从而建立通信连接。 总之,epmd是Erlang分布式系统中的重要组件,负责节点之间的服务发现和端口分配,从而支持分布式通信。
