CakePHP cache was unable to write in Centos 7
Okay, this helped me:
setsebool -P httpd_unified 1put this in console
sudo chmod -R 777 tmp always worked for me, once bash in the app folder
Beside checking file/folder ownership and permissions, check if you have SELinux properly configured. In my local env, I prefer to switch it off commpletely.
setenforce 0
