Your OTP version? And your EMQ version?

[gilbertwong96]

You need to use Erlang OTP 20 to compile this project . The default edition of Erlang OTP on Cent OS 7 is too old to compile the latest emqtt correctly.

[gilbertwong96]

This problem still caused by rebar. Usually, if you make project with erlang.mk . Rebar would be installed automatically by erlang.mk . The error log shows that crypto start failed . Did you build your erlang from source code . Please make sure that your all libraries of your erlang runtime have been built sucessfully.

yes, I build erlang by myself.
use the command :
cd otp_src_20.0 && ./configure && make && make install

[wumao]

thank you. @gilbert-wong , you are right.
apt-get install libssl-dev
then build erlang, now it works.
