erlang从机：启动/2连接被拒绝

操作系统是MacOSLion。 如果命令是

'erl-name aa'

和

'erl-name bb'

，则两个节点之间的longname连接正常

但如果使用slave:start/2，则会出现如下连接错误：

(emacs@yus-iMac.local)33> slave:start('yus-iMac.local',bb).

longname测试如下所示：

yus-iMac:~ yuchen$ erl -name cc
Erlang R15B (erts-5.9) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]

默认情况下，当您通过

slave

API启动节点时，将使用RSH连接。阅读下列文件：

“与主节点在同一主机上启动的从属节点继承某些 主目录中的环境值，例如当前目录和 环境变量。关于 环境当从机在另一台主机上启动时，请阅读 rsh计划的文件。”

也许这就是问题所在。您应该验证主机上的RSH连接是否正常。启动“erl”命令时，可以在命令行上指定rsh程序的替代方案：

erl -rsh ssh

希望这能把你带向正确的方向。我没有运行Lion，所以我真的不知道。

您声明：“两个节点之间的longname连接正常”。你是如何尝试的？我在上一篇文章中添加了长名称测试。我尝试了这个方向。这对狮子座的人来说似乎很难。它的ssh不包含ssh askpass。非常感谢你。
