Once your application is complete, or even before that you’ll want to deploy it. There are a few things you should do when deploying a CakePHP application.
You are encouraged to create a git commit and pull or clone that commit or
repository on your server and run composer install
.
While this requires some knowledge about git and an existing install of git
and composer
this process will take care about library dependencies and file
and folder permissions.
Be aware that when deploying via FTP you will at least have to fix file and folder permissions.
You can also use this deployment technique to setup a staging- or demo-server (pre-production) and keep it in sync with your dev box.
Adjusting app.php, specifically the value of debug
is extremely important.
Turning debug = false
disables a number of development features that should
never be exposed to the Internet at large. Disabling debug changes the following
types of things:
Debug messages, created with pr()
, debug()
and dd()
are
disabled.
Core CakePHP caches are by default flushed every year (about 365 days), instead of every 10 seconds as in development.
Error views are less informative, and give generic error messages instead.
PHP Errors are not displayed.
Exception stack traces are disabled.
In addition to the above, many plugins and application extensions use debug
to modify their behavior.
You can check against an environment variable to set the debug level dynamically
between environments. This will avoid deploying an application with debug
true
and also save yourself from having to change the debug level each time
before deploying to a production environment.
For example, you can set an environment variable in your Apache configuration:
SetEnv CAKEPHP_DEBUG 1
And then you can set the debug level dynamically in app.php:
$debug = (bool)getenv('CAKEPHP_DEBUG');
return [
'debug' => $debug,
.....
];
If you’re throwing your application out into the wild, it’s a good idea to make sure it doesn’t have any obvious leaks:
Ensure you are using the Cross Site Request Forgery component or middleware.
You may want to enable the Security component. It can help prevent several types of form tampering and reduce the possibility of mass-assignment issues.
Ensure your models have the correct Validation rules enabled.
Check that only your webroot
directory is publicly visible, and that your
secrets (such as your app salt, and any security keys) are private and unique
as well.
Setting the document root correctly on your application is an important step to
keeping your code secure and your application safer. CakePHP applications
should have the document root set to the application’s webroot
. This
makes the application and configuration files inaccessible through a URL.
Setting the document root is different for different webservers. See the
URL Rewriting documentation for webserver specific
information.
In all cases you will want to set the virtual host/domain’s document to be
webroot/
. This removes the possibility of files outside of the webroot
directory being executed.
Class loading can take a big share of your application’s processing time. In order to avoid this problem, it is recommended that you run this command in your production server once the application is deployed:
php composer.phar dump-autoload -o
Warning
If you are using deprecated class names in your project or plugins, don’t
combine this with -a
/--classmap-authoritative
. This breaks the class aliases.
Instead, you can use the mentioned option 2b instead
using --apcu
as additional optimization if APCu is installed.
Since handling static assets, such as images, JavaScript and CSS files of
plugins, through the Dispatcher
is incredibly inefficient, it is strongly
recommended to symlink them for production. This can be done by using
the plugin
shell:
bin/cake plugin assets symlink
The above command will symlink the webroot
directory of all loaded plugins
to appropriate path in the app’s webroot
directory.
If your filesystem doesn’t allow creating symlinks the directories will be copied instead of being symlinked. You can also explicitly copy the directories using:
bin/cake plugin assets copy
After deployment of an update you might also want to run bin/cake schema_cache
clear
, part of the Schema Cache Shell shell.
