如何在Erlang中操作Redis？

用ERedis：

下載和編譯：

git clone git://github.com/wooga/eredis.git
cd eredis
./rebar compile

在console中使用：

erl -pa ebin/
{ok, C} = eredis:start_link().
{ok, <<"OK">>} = eredis:q(C, ["SET", "foo", "bar"]).
{ok, <<"bar">>} = eredis:q(C, ["GET", "foo"]).

在模塊中使用：

save_order_id({Pid, DynData}) ->
	{ok, Rds} = eredis:start_link(),
	{_,Val} = ts_dynvars:lookup(order_id, DynData),
	Id = binary_to_list(Val),
	{ok, _} = eredis:q(Rds, ["RPUSH", "order_list", Id]).

get_order_id({Pid, DynData}) ->
	{ok, Rds} = eredis:start_link(),
	{ok, Id} = eredis:q(Rds, ["LPOP", "order_list"]),
	Id.
