2 创建项目

按照下面的命令创建一个新的项目test_rebar：

 $ mkdir test_rebar
 $ cd test_rebar/
 $ cp ../rebar/rebar .
 $ ./rebar create-app
 $ mkdir rel
 $ cd rel
 $ ../rebar create-node
 $ vi reltool.config
 $ cd ..
 $ echo "{sub_dirs,[\"rel\"]}.">rebar.config
 $ ./rebar compile generate
==> rel (generate)
WARN:  'generate' command does not apply to directory ~/test_rebar

{app, mynode, [{mod_cond, app}, {incl_cond, include}]}

{app, mynode, [{mod_cond, app}, {incl_cond, include}, {lib_dir,".."}]}

3 运行

$ pwd
../test_rebar/rel/mynode/bin
$ ./mynode start
$ ./mynode attach
Attaching to /tmp//~/test_rebar/rel/mynode/erlang.pipe.1 (^D to exit)

[{mynode,[],[]},
 {sasl,"SASL  CXC 138 11","2.4.1"},
 {stdlib,"ERTS  CXC 138 10","2.2"},
 {kernel,"ERTS  CXC 138 10","3.0.3"}]
