[erlang-questions] How to call a locally Pid cross node on Distributed Application!

[wenew zhang]

the source code as below,on the first time start the two nodes,i get output
like this:
(socketservernode@REDACTED)2> spawn(
authservernode@REDACTED,authserver1,start,[]).
<5869.52.0>
Authserver start
Authserver init with []

and then i start i again,
(socketservernode@REDACTED)3> Pid=spawn(
authservernode@REDACTED,authserver1,start,[]).
Authserver start
<5869.54.0>

No" Authserver init with [] " output  on the Init parts,
on the terminate:    io:format("Terminating...~n"),
can't find this output,
i use rb nether find log-message on the socketservernode no authservernode

Best Regards

Wenew Zhang

-module(authserver1).

-behaviour(gen_server).

%% gen_server callbacks
-export([init/1, handle_call/3, handle_cast/2, handle_info/2, terminate/2,
         code_change/3]).
-export([start_link/0,start/0]).

start_link() ->
    io:format("Authserver start_link~n"),
    gen_server:start_link({global, ?MODULE}, ?MODULE, [],[]).

start() ->
    io:format("Authserver start~n"),
    gen_server:start({global, ?MODULE}, ?MODULE, [],[]).

init([]) ->
    process_flag(trap_exit, true),
    io:format("Authserver init with []~n"),
    {ok,0}.



handle_call({213,Uid,Pwd},_From,State) ->
    io:format("PLLogin id:~w Uid:~w   Pwd:~w~n",[213,Uid,Pwd]),
    {reply,213, State}.

handle_cast(_Msg, State) ->
    {noreply, State}.

handle_info({213,Uid,Pwd},State) ->
    io:format("PLLogin id:~w Uid:~w   Pwd:~w~n",[213,Uid,Pwd]),
    {noreply, State}.

terminate(_Reason, _N) ->
    io:format("Terminating...~n"),
    ok.


code_change(_OldVsn, State, _Extra) ->
    {ok, State}.
