我有一个简单的主管，看起来像这样

-module(a_sup).
-behaviour(supervisor).

%% API
-export([start_link/0, init/1]).

start_link() ->
  supervisor:start_link({local,?MODULE}, ?MODULE, []).

init(_Args) ->
  RestartStrategy = {simple_one_for_one, 5, 3600},
  ChildSpec = {
    a_gen_server,
    {a_gen_server, start_link, []},
    permanent,
    brutal_kill,
    worker,
    [a_gen_server]
  },
  {ok, {RestartStrategy,[ChildSpec]}}.

当我在shell上运行这个命令时，它运行得非常好。但是现在我想在不同的节点上运行这个supervisor的不同示例，名为foo和bar（从一个名为main erl -sname main的单独节点开始，以erl -sname foo和erl -sname bar启动）。

从消息中看，这个调用似乎希望supervisor是一个gen_server？当我尝试在节点上初始化一个gen_server时，它运行得很好，但对于supervisor就不行了。我似乎不知道在本地/远程节点上初始化supervisor是否有什么不同，如果有，我们应该怎么做来解决这个问题？
