Move and process millions of MQTT messages per second. The EMQX v5.0 has been verified in [test scenarios](https://www.emqx.com/en/blog/reaching-100m-mqtt-connections-with-emqx-5-0) to scale to 100 million concurrent device connections, which is a critically important milestone for IoT designers. It also comes with plenty of exciting new features and huge performance improvements, including a more powerful [rule engine](https://www.emqx.com/en/solutions/iot-rule-engine), enhanced security management, Mria database extension, and much more to enhance the scalability of IoT applications. During the last several years, EMQX has gained popularity among IoT companies and is used by more than 20,000 global users from over 50 countries, with more than 100 million IoT device connections supported worldwide. For more information, please visit [EMQX homepage](https://www.emqx.io/). ## Get Started #### EMQX Cloud The simplest way to set up EMQX is to create a managed deployment with EMQX Cloud.

EMQX requires OTP 22 or 23 for version 4.3, and OTP 24 for 4.4 and 5.0. ```bash git clone https://github.com/emqx/emqx.git cd emqx make _build/emqx/rel/emqx/bin/emqx console ``` For 4.2 or earlier versions, release has to be built from another repo. ```bash git clone https://github.com/emqx/emqx-rel.git cd emqx-rel make _build/emqx/rel/emqx/bin/emqx console ``` ### Building on Apple silicon (M1, M2) Homebrew on Apple silicon [changed default location of it's home directory](https://github.com/Homebrew/brew/issues/9177) from `/usr/local` to `/opt/homebrew` and as a result a few things broke in the process. Concerning EMQX, when you install `unixodbc` package (one of the dependencies) via Homebrew, and build Erlang/OTP with [kerl](https://github.com/kerl/kerl), kerl will not be able to find `unixodbc`. Here is how to solve it: ```bash brew install unixodbc kerl sudo ln -s $(realpath $(brew --prefix unixodbc)) /usr/local/odbc export CC="/usr/bin/gcc -I$(brew --prefix unixodbc)/include" export LDFLAGS="-L$(brew --prefix unixodbc)/lib" kerl build 24.3 mkdir ~/.kerl/installations kerl install 24.3 ~/.kerl/installations/24.3 . ~/.kerl/installations/24.3/activate ``` Then you can proceed with `make`. ## License See [LICENSE](./LICENSE).
