Ejabberd：mod_roster_odbc 未启动

Question

启用 mod_roster_odbc 模块后，当我尝试重新启动服务器时，我在日志中看到以下内容。

2015-02-26 14:07:03.725 [critical] <0.836.0>@gen_mod:start_module:94 Problem     starting the module mod_roster_odbc for host <<"localhost">>

2015-02-26 14:07:03.726 [critical] <0.836.0>@gen_mod:start_module:99     ejabberd initialization was aborted because a module start failed.
The trace is [{mod_roster_odbc,start,[<<"localhost">>,[]],[]},    {gen_mod,start_module,3,[{file,"src/gen_mod.erl"},{line,83}]},{lists,foreach,2,    [{file,"lists.erl"},{line,1336}]},{ejabberd_app,start,2,    [{file,"src/ejabberd_app.erl"},{line,69}]},{application_master,start_it_old,4,    [{file,"application_master.erl"},{line,272}]}].
(END)
