I have had to use the
app/console cache:clear command
to solve a problem when generating an entity.
I am now unable to load my homepage on :
http://localhost/projet_etienne/web/app_dev.php
it says :
RuntimeException: Failed to write cache file "/var/www/projet_etienne/app/cache/dev/classes.php".
I don't understand much about this cache business!
In my app/cache
folder, I got a dev
, a dev_new
, a dev_old
folder. Is that normal?
the
app/console cache:clear
generates by the way a :
[ErrorException] Warning: rename(/var/www/projet_etienne/app/cache/dev,/var/www/projet_etien
ne/app/cache/dev_old): Directory not empty in /var/www/projet_etienne/vendo
r/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Command/CacheClearComm
and.php line 77
please help!
This question is related to
symfony
If the folder is already writable so thats not the problem.
You can also just navigate to /www/projet_etienne/app/cache/
and manualy remove the folders in there (dev, dev_new, dev_old).
Make sure to SAVE a copy of those folder somewhere to put back if this doesn't fix the problem
I know this is not the way it should be done but it worked for me a couple of times now.
if symfony version less than 2.8
sudo chmod -R 777 app/cache/*
_x000D_
if symfony version great than or equal 3.0
sudo chmod -R 777 var/cache/*
_x000D_
i executed:
ps aux | grep apache
and got something like that:
root 28147 0.0 5.4 326336 27024 ? Ss 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28150 0.0 1.3 326368 6852 ? S 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28151 0.0 4.4 329016 22124 ? S 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28152 0.1 6.0 331252 30092 ? S 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28153 0.0 1.3 326368 6852 ? S 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28154 0.0 1.3 326368 6852 ? S 20:06 0:00 /usr/sbin/apache2 -k start
www-data 28157 0.0 1.3 326368 6852 ? S 20:06 0:00 /usr/sbin/apache2 -k start
user 28297 0.0 0.1 15736 924 pts/4 S+ 20:12 0:00 grep --color=auto apache
so my user with no access turned out to be www-data
thus i executed commands:
sudo chown -R www-data app/cache
sudo chown -R www-data app/logs
and it solved access errors.
Never-ever use unsecure 777 for solving specific access probles:
sudo chmod -R 777 app/cache
sudo chmod -R 777 app/logs
Just use this acl cmd, next time the files inside var are created it will have the r/w/x permission for www-data user.
cd var
rm -rf *
cd ..
setfacl -d -m u:www-data:rwx var
Cmd explanation:
setfacl -> Set acl command
-d -> default behavior
-m -> modify
u:www-data: -> for user
rwx -> adding permissions
var -> on the folder
You probably aborted a clearcache halfway and now you already have an app/cache/dev_old.
Try this (in the root of your project, assuming you're on a Unixy environment like OS X or Linux):
rm -rf app/cache/dev*
Maybe you forgot to change the permissions of app/cache app/log
I'm using Ubuntu so
sudo chmod -R 777 app/cache
sudo chmod -R 777 app/logs
sudo setfacl -dR -m u::rwX app/cache app/logs
Hope it helps..
I move the whole directory from my Windows installation to a unix production server and I got the same error. To fix it, I just ran these two lines in unix and everything started to run fine
rm -rf app/cache/*
rm -rf app/logs/*
If you face this error when you start Symfony project with docker (my Symfony version 5.1). Or errors like these:
Uncaught Exception: Failed to write file "/var/www/html/mysite.com.local/var/cache/dev/App_KernelDevDebugContainer.xml"" while reading upstream
Uncaught Warning: file_put_contents(/var/www/html/mysite.com.local/var/cache/dev/App_KernelDevDebugContainerDeprecations.log): failed to open stream: Permission denied" while reading upstream
Fix below helped me.
In Dockerfile for nginx container add line:
RUN usermod -u 1000 www-data
In Dockerfile for php-fpm container add line:
RUN usermod -u 1000 www-data
Then remove everything in directories "/var/cache", "/var/log" and rebuild docker's containers.
Most likely it means that the directory and/or sub-directories are not writable. Many forget about sub-directories.
Symfony 2
chmod -R 777 app/cache app/logs
Symfony 3 directory structure
chmod -R 777 var/cache var/logs
Permissions solution by Symfony (mentioned previously).
Permissions solution by KPN University - additionally includes an screen-cast on installation.
Note: If you're using Symfony 3 directory structure, substitute app/cache
and app/logs
with var/cache
and var/logs
.
