One important Symfony requirement is that the
var directory must be
writable both by the web server and the command line user.
On Linux and macOS systems, if your web server user is different from your command line user, you need to configure permissions properly to avoid issues. There are several ways to achieve that:
Edit your web server configuration (commonly
for Apache) and set its user to be the same as your CLI user (e.g. for Apache,
If this solution is used in a production server, be sure this user only has limited privileges (no access to private data or servers, execution of unsafe binaries, etc.) as a compromised server would give to the hacker those privileges.
On macOS systems, the
chmod command supports the
+a flag to define an
ACL. Use the following script to determine your web server user and grant the
1 2 3 4 5 6
$ rm -rf var/cache/* $ rm -rf var/logs/* $ HTTPDUSER=$(ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1) $ sudo chmod +a "$HTTPDUSER allow delete,write,append,file_inherit,directory_inherit" var $ sudo chmod +a "$(whoami) allow delete,write,append,file_inherit,directory_inherit" var
Most Linux and BSD distributions don't support
chmod +a, but do support
another utility called
setfacl. You may need to install
enable ACL support on your disk partition before using it. Then, use the
following script to determine your web server user and grant the needed permissions:
1 2 3 4
$ HTTPDUSER=$(ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1) # if this doesn't work, try adding `-n` option $ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:$(whoami):rwX var $ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:$(whoami):rwX var
setfacl command sets permissions for future files and folders,
while the second one sets permissions on the existing files and folders.
Both of these commands assign permissions for the system user and the Apache
setfacl isn't available on NFS mount points. However, storing cache and
logs over NFS is strongly discouraged for performance reasons.
If none of the previous methods work for you, change the
umask so that the
cache and log directories are group-writable or world-writable (depending
if the web server user and the command line user are in the same group or not).
To achieve this, put the following line at the beginning of the
1 2 3 4 5
umask(0002); // This will let the permissions be 0775 // or umask(0000); // This will let the permissions be 0777
umask is not thread-safe, so the ACL methods are recommended
when they are available.
