EMQX is an open-source MQTT message broker based on the Erlang/OTP platform. OpenBSD is a free and open-source Unix-like operating system. In this tutorial, we will guide you on how to install EMQX on OpenBSD.
Before we start installing EMQX on OpenBSD, make sure that you have the following prerequisites:
The first step is to install some dependencies required by EMQX. OpenBSD does not have some of the dependencies that EMQX requires, so we need to install them manually.
sudo pkg_add gcc git make automake autoconf openssl
EMQX requires a specific version of the Erlang/OTP platform. OpenBSD comes with its own version of the OTP platform, which is often updated but may not be the correct version that EMQX requires. Therefore, we will download and install the required OTP version from source.
cd /tmp
ftp https://github.com/erlang/otp/archive/OTP-23.3.4.7.tar.gz
tar -xzvf OTP-23.3.4.7.tar.gz
cd otp-OTP-23.3.4.7
./otp_build setup -a
sudo ln -s /usr/local/lib/erlang/bin/erl /usr/local/bin/
Now that we have all the prerequisites installed, we can proceed to download and install EMQX.
cd /tmp
git clone https://github.com/emqx/emqx-rel.git
cd emqx-rel
make
This will download and build EMQX. The build process may take a few minutes.
Once the build process is complete, we can start EMQX using the following command:
./_build/emqx/rel/emqx/bin/emqx start
You can now access the EMQX dashboard by opening your web browser and navigating to http://localhost:18083.
In this tutorial, we have shown you how to install EMQX on OpenBSD. EMQX is an open-source MQTT message broker based on the Erlang/OTP platform. It is a powerful tool for handling message brokering in your IoT projects.
