Changing cache_dir and log_dir with Symfony2

Because of deployment constraints, I would like to have the log and cache directories used by my Symfony2 application somewhere under /var/... in my file system. For this reason, I am looking for a way to configure Symfony and to o开发者_StackOverflow中文版verride the default location for these two directories.

I have seen the kernel.cache_dir and kernel.log_dir and read the class Kernel.php. From what I have seen, I don't think that it is possible to change the dir locations by configuration and I would have to patch the Kernel.php class.

Is that true, or is there a way to achieve what I want without modifying the framework code?

Add the following methods to app/AppKernel.php (AppKernel extends Kernel) making them return your preferred paths:

public function getCacheDir()
{
    return $this->rootDir . '/my_cache/' . $this->environment;
}

public function getLogDir()
{
    return $this->rootDir . '/my_logs';
}

I was happy to find your post, but I was a little bit confused of the unhelping answers.

I got the same problem and found out that the logs are depending on the config parameter kernel.logs_dir.

So I just added it to my config.yml parameters:

kernel.logs_dir: /var/log/symfonyLogs

I hope it will helpfull for you even, if its a late answer.

i think the easiest way is to link the folder to another place. We have made this on the prod server but when you develop local perhaps on windows its a bit complicated to set the symlinks.

ln -s /var/cache/ /var/www/project/app/cache

something like this.

I would like to offer an alternative and that is to set environment variables to change these directories. This way it's easier to set depending on the stage. (testing, production or development)

export SYMFONY__KERNEL__CACHE_DIR "/your/directory/cache"
export SYMFONY__KERNEL__LOGS_DIR "/your/directory/logs"

Environment variables can also be set in the virtual host with SetEnv. When reading kernel parameters symfony will look for all the $_SERVER variables that start with SYMFONY__, strip the first part and convert all the double underscores into a .

In symfony you can override the cache (and logs) directory by extending the method in AppKernel.

// app/appKernel.php
class AppKernel extends Kernel
{
    // ...

    public function getCacheDir()
    {
        return $this->rootDir.'/'.$this->environment.'/cache';
    }
}

I used the configuration solution from Dragnic but I put the paths in the parameters.yml file because this file is ignored by git. in other words, it's not synchronized from my PC to the git repository so there is no impact in the prod environment.

# app/config/parameters.yml
parameters:
    database_driver: pdo_mysql
    [...]
    kernel.cache_dir: "T:/project/cache"
    kernel.logs_dir: "T:/project/logs"

Configuration: Windows7, WAMP 2.4 and Symfony 2.3.20.

But you have to know that:

Overwriting the kernel.cache_dir parameter from your config file is a very bad idea, and not a supported way to change the cache folder in Symfony.

It breaks things because you would now have different cache folders for the kernel Kernel::getCacheDir() and for the parameter.

So you should use it only in dev environment and if you don't want to change the content of the app/AppKernel.php file, otherwise see the other answers.

No accepted answer, and a really old question, but I found it with google, so I post here a more recent way to change the cache directory, and the logs directory, (source here)

• remember, short syntax for arrays require php 5.4

• you can select the env to modify, and manage different cache and logs directories if you want

  public function getCacheDir()
  {
      if (in_array($this->environment, ['prod', 'test'])) {
      return '/tmp/cache/' .  $this->environment;
  }
  
  return parent::getCacheDir();
  }
  
  public function getLogDir()
  {
      if (in_array($this->environment, ['prod', 'test'])) {
      return '/var/log/symfony/logs';
  }
  
  return parent::getLogDir();
  }
