{["src/*"],[{outdir, "ebin"}]}.
src/* 表示编译src目录下所有的源代码文件
outdir 指定编译后的beam文件输出目录
erl -make all
cd config
erl -name wulin@192.168.1.1 -setcookie mywulin -boot start_sasl -noshell -config config -pa ../ebin/ -s wulin_app start
-noshell 禁止输入
-config xxx 加载文件名为xxx.config的配置
-pa 指定目录
-s xxx yyy 启动xxx模块的yyy函数

可以在程序内使用application:get_env/2获取这里定义的变量
示例:application:get_env(sasl, error_logger_mf_dir).
返回{ok,"../logs"}
{
application, server % 对应文件名
, [{description, "Server"}
, {vsn, ‘1.0a‘}
, {modules, []}
, {registered, []}
, {applications, [kernel, stdlib, sasl]} % 依赖库
, {env, [{author, "demo"}]}
, {mod, {wulin_app, [12321]}} % 依赖模块,主模块
, {start_phases, []}]
}.
server(app名)必须和server.app(文件名)一致
-module(wulin_app).
-behaviour(application).
-export([start/2,start/0, stop/1]).
start() ->
application:start(server).
start(_Type, [A]) ->
util:debug("Server Starting.... ~p ~n", [A]),
util:debug("Server Starting.... ~n", []),
{ok, Pid} = wulin_sup:start_link(),
util:debug("Server Started in ~p ~n", [Pid]),
{ok, Pid}.
stop(_State) ->
io:format("Server Stoped..... ~n").
application:start(server)中的server对应server.app中的server
-module(wulin_sup).
-behaviour(supervisor).
-export([start_link/0,init/1]).
start_link() ->
supervisor:start_link({local,?MODULE}, ?MODULE, []).
init([]) ->
{ok, {{one_for_one, 3, 10},[
{demo, {demo, start, []}, permanent, 10000, worker, []}
]}}.
-module(demo).
-export([start/0]).
start() ->
util:debug("xxxxx ~n", []),
{‘ok‘, self()}.
-module(util).

debug(F, Args) ->
{ok, LogPath} = application:get_env(sasl, error_logger_mf_dir),
File = LogPath ++ "/debug.txt",
{ok, Steam} = file:open(File, [write, append]),
io:format(Steam, F, Args),
file:close(Steam).

start.bat -> wulin_app:start/0 -> server.app ->
