Warning: You are browsing the documentation for Symfony 5.0, which is no longer maintained.
Read the updated version of this page for Symfony 6.0 (the current stable version).
In Symfony 3.x, you needed to do some extra work to make sure that your cache directory was writable. But that is no longer true! Since Symfony 4, everything works automatically:
- In the
umask()is used in
public/index.phpso that any created files are writable by everyone.
- In the
prodenvironment (i.e. when
0), as long as you run
php bin/console cache:warmup, no cache files will need to be written to disk at runtime. The only exception is when using a filesystem-based cache, such as Doctrine's query result cache or Symfony's cache with a filesystem provider configured.
- In all environments, the log directory (
var/log/by default) must exist and be writable by your web server user and terminal user. One way this can be done is by using
chmod -R 777 var/log/. Be aware that your logs are readable by any user on your production system.
