Enables running Symfony2 applications with the AppServer-in-PHP (AiP). AiP simplifies application deployment greatly by not requiring a normal web server, and makes Symfony2 operations more efficient by keeping the framework persistent between requests.
Users of other PHP frameworks like Midgard MVC or Flow3 have reported performance increases between 2 and 4 times faster by running their systems on AiP instead of the traditional way of serving PHP.
AiP is an application server for PHP applications that has been written in PHP itself. You can either run it as a full HTTP server, in which situation no regular web server like Apache is needed. Or you can set it up to be a FastCGI provider if you run more than just PHP on your server.
The AppServerBundle integrates AiP with the Symfony2 framework. The points of integration are the following:
- Your Symfony2 application is started by the
aip appcommand, which launches the AppServerBundle Application
- The Application bootstraps Symfony2 and creates instances of the Symfony2 AppKernels configured in
- When AiP receives a request, the
__invokemethod of the Application is run, generating a regular Symfony2 Request object and telling AppKernel to Handle it
- When request handling has completed the status code, headers, and contents of the Response object are passed to AiP
- AiP sends the response to the browser
Install AppServer-in-PHP either via PEAR:
$ pear channel-discover pear.indeyets.pp.ru $ pear install indeyets/aip
...or by installing the AiP repository under your
vendors directory. AiP requires the
php-cli package to run, as it is basically a command-line PHP script.
Install this bundle under your
vendors directory and add the
Midgard namespace to your
autoload.php. You can automate the install by adding the following to your
[AppServerBundle] git=http://github.com/bergie/MidgardAppServerBundle.git target=Midgard/AppServerBundle
aip.yaml.example file from this bundle to your
app directory. You can edit it as necessary. By default it sets up two workers to listen to
http://localhost:8001, running your
If you have multiple application kernels, you have to configure them in your
aip.yml. For example, this is how Lichess can be configured:
symfony.kernels: - path: / kernel: AppKernel kernelFile: AppKernel.php environment: dev debug: false - path: /xhr_dev.php kernel: XhrKernel kernelFile: ../xhr/XhrKernel.php environment: dev debug: false
AppServerBundle will not work with the Symfony's
NativeSessionStorage implementation, so it supplies its own
SessionStorage implementation. Switch to that in
framework: session: storage_id: session.storage.aip
Start your server with:
$ aip app app/aip.yaml
The AppServerBundle is still under heavy development, and you may still run into issues, or find things that could be optimized. Contributions for making it more reliable are very welcome.
Just fork the AppServerBundle repository on GitHub and send pull requests.
