symfony2 : failed to write cache directory - symfony

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!

For a GOOD and definite solution see the Setting up Permissions section in Installing and Configuring Symfony section :
Setting up Permissions
One common issue when installing Symfony is that the app/cache and
app/logs directories must be writable both by the web server and the
command line user. On a UNIX system, if your web server user is
different from your command line user, you can try one of the
following solutions.
Use the same user for the CLI and the web server
In development environments, it is a common practice to use the same
UNIX user for the CLI and the web server because it avoids any of
these permissions issues when setting up new projects. This can be
done by editing your web server configuration (e.g. commonly
httpd.conf or apache2.conf for Apache) and setting its user to be the
same as your CLI user (e.g. for Apache, update the User and Group
values).
Using ACL on a system that supports chmod +a
Many systems allow you to use the chmod +a command. Try this first,
and if you get an error - try the next method. This uses a command to
try to determine your web server user and set it as HTTPDUSER:
$ rm -rf app/cache/*
$ rm -rf app/logs/*
$ HTTPDUSER=`ps aux | 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" app/cache app/logs
$ sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
Using ACL on a system that does not support chmod +a
Some systems don't support chmod +a, but do support another utility
called setfacl. You may need to enable ACL support on your partition
and install setfacl before using it (as is the case with Ubuntu). This
uses a command to try to determine your web server user and set it as
HTTPDUSER:
$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
For Symfony 3 it would be:
$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var/cache var/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX var/cache var/logs
If this
doesn't work, try adding -n option.
Without using ACL
If none of the previous methods work for you, change the umask so that
the cache and log directories will be 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 app/console, web/app.php and web/app_dev.php files:
umask(0002); // This will let the permissions be 0775
// or
umask(0000); // This will let the permissions be 0777
Note that using the ACL is recommended when you have access to them on your server
because changing the umask is not thread-safe.

source :
Failed to write cache file "/var/www/myapp/app/cache/dev/classes.php" when clearing the cache

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
Additional Resources
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.

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.

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/*

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

if symfony version less than 2.8
sudo chmod -R 777 app/cache/*
if symfony version great than or equal 3.0
sudo chmod -R 777 var/cache/*

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.

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

Unable to write cache symfony2

RuntimeException in ClassCollectionLoader.php line 239:
Failed to write cache file "/var/www/fareast/app/cache/dev/classes.php".
I have this error when I run my project in symfony2.
I have nginx as my web server and centOS 7 as my OS.
I tried deleting the cache folder manually and by
php app/console cache:clear
then I did a bad practice to app/cache and app/logs
chmod -R 777
but I have the same error.
/var/log/nginx/error.log is also empty.
Do you recommend other solutions?
Or do I have to install some php5 libraries for cache?
Setting 777 permissions do nothing, because when webserver user write folders to it, the folders belong to this user, and you, as command line user haven't access to them, and vice versa. Set permissions in correct way: http://symfony.com/doc/current/book/installation.html#book-installation-permissions
In symfony3 i've faced the same issue...
So, problem would not solve only using "cache clear"
You have to change (R/W)permission of cache folder in your project
For ex: "projectname/var/cache"
Now refresh...
If still issue is coming, change(R/W)permission of logs folder in your project
For ex: "projectname/var/logs"
You have to use the following script to determine your web server user and grant the needed permissions:
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 -R +a "$HTTPDUSER allow delete,write,append,file_inherit,directory_inherit" var
sudo chmod -R +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" var

Giving a default permission for cache folder

The problem is when I clear caches in my Symfony project on production environment, I should type this command for giving right permissions to cache folder:
cd app/cache
sudo chmod -R a+w *
But is there any way to not typing these commands each time?
try this
sudo setfacl -dR -m u::rwX app/cache

Exception handling app/logs/dev.log

The stream or file "/home/nick/projects/Symfony/app/logs/dev.log" could not
be opened: failed to open stream: Permission denied
I get it in symfony.
I know that I can go to app/logs and delete dev.log but this is happening to often and is annoying to delete it again and againand again.
Is there any way to make it just disapear?
LE: I guess, that I got the reply.
I run the comands prefixed with sudo.
Eg: sudo php app/console generate:bundle --namespace=Acme/StoreBundle will work like a charm.
nick#ptb:~/projects/Symfony$ ls -al app/logs
total 76
drwxrwxrwx+ 2 nick nick 4096 nov 24 15:16 .
drwxr-xr-x 6 nick nick 4096 nov 24 15:28 ..
-rw-rw-r--+ 1 www-data www-data 59583 nov 24 16:25 dev.log
-rw-rw-r--+ 1 nick nick 0 oct 6 15:55 .gitkeep
I think that you create directory app/logs as sudo (root), so symfony doesn't have permissions to write into the file dev.log. Manually remove directory app/logs (and all contents), create it as normal user and setup up permissions, like they are described in the official documentation http://symfony.com/doc/current/book/installation.html.
Something like:
$ sudo rm -rf app/logs
$ mkdir app/logs
$ HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
$ sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
Or use any other option which is described in official documentation.
If this not works then please paste us result of command:
$ ls -al app/logs
In my case, I used CentOS 7 and I solved it by set SELINUX=disabled as follow.
- sudo nano /etc/selinux/config
- Edit the file by set SELINUX=disabled
- Restart again then it worked !
I tested and tried many method included chmod, chwon, setfacl, etc but it cannot solve the problem until I tried above solution and it worked!
You should have a look at this http://symfony.com/doc/current/book/installation.html#configuration-and-setup.
UPD
Sometimes the solutions using ACL won't work, in this case try the forth option 4. Use the same user for the CLI and the web server
Use commands prefixed with sudo. I also got this error when I tried to run the server. Then I used 'sudo' and the error disappeared.
$ sudo php bin/console server:run

Unable to write cache

Hi all im working with Symfony2. I dont have problems with the project in my computer but when i upload the files in the web server, fails for cache permissions.
I set the permissions in my computer with this steps:
$ rm -rf app/cache/*
$ rm -rf app/logs/*
$ APACHEUSER=`ps aux | grep -E '[a]pache|[h]ttpd' | grep -v root | head -1 | cut -d\ -f1`
$ sudo setfacl -R -m u:$APACHEUSER:rwX -m u:`whoami`:rwX app/cache app/logs
$ sudo setfacl -dR -m u:$APACHEUSER:rwX -m u:`whoami`:rwX app/cache app/logs
As sugest The Doc.
So, upload the app/cache and app/logs (empty) folders to my webserver.
Whe in try access to the web project, Symfony says:
Fatal error: Uncaught exception 'RuntimeException' with message 'Could
not create cache directory
"/home/coleman/public_html/apps/app/cache/prod/annotations"
I check the folder with Filezilla, and the permissions are 666 (read and write for all).
I dont know that are wrong.
Any ideas ?.
See this link:
Configuration and Setup
It's pretty common issue. You need to configure permissions though ACL...
Is your project name "apps" ? If not, seems like you put your web folder content at root without modify the relative paths in your app.php

Permissions issues on Symfony2

This question has been asked several times but none of the solutions fix it in my situation.
I am running Apache on Mac OSX Lion. This http://localhost/Symfony/web/config.php URL triggers 2 major problems:
Change the permissions of the "app/cache/" directory so that the web server can write into it.
Change the permissions of the "app/logs/" directory so that the web server can write into it.
Following the guide under "Setting up Permissions":
rm -rf app/cache/*
rm -rf app/logs/*
sudo chmod +a "_www allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
That doesn't solve the problems, so then I tried:
sudo chmod -R 777 app/cache
That doesn't work either. Any ideas how to fix this?
Some preliminary explanations:
In order to enhance the performance of your website, Symfony2 needs to cache a lot of data and it does this by writing compiled files into your app/cache directory.
In order to propose powerful debugging and monitoring facilities, Symfony2 needs to track your website behavior and it does this by writing trace files into your app/logs directory.
Some words about Apache:
Apache runs under a specific user and a specific group (usually www-data for both, but you have to check your installation to find the used ones. For example, if you search in the /etc/apache2/envvars in Linux, you will have two variables APACHE_RUN_USER=www-data and APACHE_RUN_GROUP=www-data).
It means that when you build your website upon Symfony2 shoulders and you run it under Apache, every writes and reads are made on behalf of the Apache user and group.
Analyze of your problems:
First of all you have errors like:
Change the permissions of the "app/cache/" directory so that the web server can write into it.
Change the permissions of the "app/logs/" directory so that the web server can write into it.
because your app/cache and app/logs folders are not writable for your Apache user and group.
Secondly, by executing:
sudo chmod +a "_www allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
sudo chmod +a "`whoami` allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs
you are modifying the Access Control List (ACL) of the app/cache and app/logs folders in order to grant some permissions to whoami (basically you) and to _www.
This approach does not work and can have two origins:
You are modifying ACLs, but are your kernel and your file system configured to take into account ACLs?
You are giving some permissions to whoami and to _www, but have you checked that your Apache instance runs under one of these users?
Thirdly your colleagues solve the problem by executing:
sudo chmod -R 777 app/cache
This approach works because of two reasons:
You give all permissions (reads and writes) to every user on your system (777), so you are sure that at least your Apache user and group have also the needed permissions to write in app/cache.
You do it recursively (-R), so all the nested folders created in the app/cache directory are also concerned by the new permissions.
Simple solution:
Delete the content of your app/cache and app/logs folders:
rm -rf app/cache/*
rm -rf app/logs/*
Give all permissions (reads and writes) to your app/cache and app/logs folders:
chmod 777 app/cache
chmod 777 app/logs
Remarks:
There are also other solutions (with a greater difficulty) like giving permission to the specific Apache user and group and using ACLs for fine tuning.
The guide under the "Setting up permissions" says that if your system doesn't support chmod +a you have to do this:
HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:`whoami`:rwX app/cache app/logs
If that doesn't work try this:
umask(0002); // This will let the permissions be 0775
// or
umask(0000); // This will let the permissions be 0777
First solution worked for me. I hope it helps someone with the same type of issue.
rm -rf app/cache/*
rm -rf app/logs/*
APACHEUSER=`ps aux | grep -E '[a]pache|[h]ttpd' | grep -v root | head -1 | cut -d\ -f1`
sudo setfacl -R -m u:$APACHEUSER:rwX -m u:`whoami`:rwX app/cache app/logs
sudo setfacl -dR -m u:$APACHEUSER:rwX -m u:`whoami`:rwX app/cache app/logs
Source: http://symfony.com/doc/current/book/installation.html#configuration-and-setup
The Accepted answer is great however, in my case (Centos 7 & Symfony 4.3) even after setting permissions i was still getting error. It turns out SELinux was blocking Apache.
The following worked for me(change my-project to your Symfony install folder).
sudo chcon -R -t httpd_sys_script_rw_t /var/www/my-project/var/cache/
sudo chcon -R -t httpd_sys_script_rw_t /var/www/my-project/var/log/
You can also disable SELinux but only temporarily for the current session to isolate the issue(I don't recommend this for prod)
sudo setenforce 0
