php - Symfony can't write in cache folder on CentOS 7 even with the right permissions

Solution:

I've solved this issue. Here is how.

First, Nginx and php-fpm are running using the nginx user. This user is created automaticlly when installing Nginx.

On the/etc/nginx/nginx.conf

user  nginx;
Copy code

And on the/etc/php-fpm.d/www.conf

user = nginx
group = nginx
...
...
listen.owner = nginx
listen.group = nginx
listen.mode  = 0660
Copy code

Second the permissions on the symfony app are set to 755 and the owner is changed to nginx user/group (The user Nginx and php-fpm are using)

sudo chown -R nginx:nginx /path/to/symfony

sudo chmod 0755 -R /path/to/symfony
Copy code

Then, I run two commands. The first is to ennable the httpd connections And the second allows the httpd process to read and write on the /path/to/symfony folder

sudo setsebool -P httpd_can_network_connect on

sudo chcon -R -t httpd_sys_content_rw_t /path/to/symfony
Copy code

Finanlly, restarting the Nginx service

sudo systemctl restart nginx
Copy code
