It is intended as a building block for any web +architecture regardless of its complexity, from enterprise-scale deployments to +your pet's homepage. + +Unit's native RESTful JSON API enables dynamic updates with zero interruptions +and flexible configuration, while its out-of-the-box productivity reliably +scales to production-grade workloads. We achieve that with a complex, +asynchronous, multithreading architecture comprising multiple processes to +ensure security and robustness while getting the most out of today's computing +platforms. + + +## Quick Installation + +### macOS + +``` console +$ brew install nginx/unit/unit +``` + +For details and available language packages, see the +[docs](https://unit.nginx.org/installation/#homebrew). + + +### Docker + +``` console +$ docker pull docker.io/nginx/unit +``` + +For a description of image tags, see the +[docs](https://unit.nginx.org/installation/#docker-images). + + +### Amazon Linux, Fedora, RedHat + +``` console +$ curl -sL 'https://unit.nginx.org/_downloads/setup-unit.sh' | sudo -E bash +# yum install unit +``` + +For details and available language packages, see the +[docs](https://unit.nginx.org/installation/#official-packages). + + +### Debian, Ubuntu + +``` console +$ curl -sL 'https://unit.nginx.org/_downloads/setup-unit.sh' | sudo -E bash + +# apt install unit +``` + +For details and available language packages, see the +[docs](https://unit.nginx.org/installation/#official-packages). + + +## Running a Hello World App + +Suppose you saved a PHP script as `/www/helloworld/index.php`: +``` php +<?php echo "Hello, PHP on Unit!"; ?> +``` + +To run it on Unit with the `unit-php` module installed, first set up an +application object. Let's store our first config snippet in a file called +`config.json`: + +``` json +{ + "helloworld": { + "type": "php", + "root": "/www/helloworld/" + } +} +``` + +Saving it as a file isn't necessary, but can come in handy with larger objects. + +Now, `PUT` it into the `config/applications` section of Unit's control API, +usually available by default via a Unix domain socket: + +``` console +# curl -X PUT --data-binary @config.json --unix-socket \ + /path/to/control.unit.sock http://localhost/config/applications +``` +``` json + +{ + "success": "Reconfiguration done." +} +``` + +Next, reference the app from a listener object in the `config/listeners` +section of the API. This time, we pass the config snippet straight from the +command line: + +``` console +# curl -X PUT -d '{"127.0.0.1:8000": {"pass": "applications/helloworld"}}' \ + --unix-socket /path/to/control.unit.sock http://localhost/config/listeners +``` +``` json +{ + "success": "Reconfiguration done." +} +``` + +Now Unit accepts requests at the specified IP and port, passing them to the +application process. Your app works! + +``` console +$ curl 127.0.0.1:8080 + + Hello, PHP on Unit! +``` + +Finally, query the entire `/config` section of the control API: + +``` console +# curl --unix-socket /path/to/control.unit.sock http://localhost/config/ +``` + +Unit's output should contain both snippets, neatly organized: + +``` json +{ + "listeners": { + "127.0.0.1:8080": { + "pass": "applications/helloworld" + } + }, + + "applications": { + "helloworld": { + "type": "php", + "root": "/www/helloworld/" + } + } +} +``` + +For full details of configuration management, see the +[docs](https://unit.nginx.org/configuration/#configuration-management). + + +## Community + +- The go-to place to start asking questions and share your thoughts is + our [Slack channel](https://nginxcommunity.slack.com/). + +- Our [GitHub issues page](https://github.com/nginx/unit/issues) offers + space for a more technical discussion at your own pace. + +- The [project map](https://github.com/orgs/nginx/projects/1) on + GitHub sheds some light on our current work and plans for the future. + +- Our [official website](https://unit.nginx.org/) may provide answers + not easily found otherwise. + +- Get involved with the project by contributing!
