Once your app is ready to be deployed there are a few things you should do.
You can clone your repository onto your production server and then checkout the
commit/tag you want to run. Then, run
composer install. While this requires
some knowledge about git and an existing install of
this process will take care about library dependencies and file and folder
Be aware that when deploying via FTP you will 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 local environment.
You’ll want to make a few adjustments to your application’s configuration for
a production environment. 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
Debug messages, created with
Core CakePHP caches duration are defaulted to 365 days, instead of 10 seconds as in development.
Error views are less informative, and generic error pages are displayed instead of detailed error messages with stack traces.
PHP Warnings and Errors are not displayed.
In addition to the above, many plugins and application extensions use
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_local.php:
$debug = (bool)getenv('CAKEPHP_DEBUG'); return [ 'debug' => $debug, ..... ];
It is recommended that you put configuration that is shared across all of your application’s environments in config/app.php. For configuration that varies between environments either use config/app_local.php or environment variables.
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 (CSRF) Middleware 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
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
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
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 dumpautoload -o
plugins, through the
Dispatcher is incredibly inefficient, it is strongly
recommended to symlink them for production. This can be done by using
bin/cake plugin assets symlink
The above command will symlink the
webroot directory of all loaded plugins
to appropriate path in the app’s
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
assert() internally to provide runtime type checking and
provide better error messages during development. You can have PHP skip these
assertions by updating your
php.ini to include:
; Turn off assert() code generation. zend.assertions = -1
Skipping code generation for
assert() will yield faster runtime performance,
and is recommended for applications that have good test coverage or that are
using a static analyzer.
On each deploy you’ll likely have a few tasks to co-ordinate on your web server. Some typical ones are:
Install dependencies with
composer install. Avoid using
update when doing deploys as you could get unexpected versions of packages.
Run database migrations with either the Migrations plugin or another tool.
Clear model schema cache with
bin/cake schema_cache clear. The Schema Cache Tool
has more information on this command.
