PHP Question

yii php framework "Application runtime path is not valid." exception

I tried to make a yii project for testing by executing

/var/www/html/yii/framework/yiic webapp demo


and when I go to localhost/demo I get en error:

Application runtime path "/var/www/html/demo/protected/runtime" is not valid.
Please make sure it is a directory writable by the Web server process.


At first I thought that it really isn't writable so I did:

chmod 777 /var/www/html/demo/protected/runtime


didn't work so as the last idea I executed:

chmod 777 -R /var/www/html/demo/


and I still get the same exception. Any ideas on what might be wrong?

---EDIT---

FFS this drives me nuts

Answer

Looks like you might have SELinux turned on, which enforces it's own security policies and can be a real pain for web apps and very annoying when it ends up resulting in errors like this. Whenever you have funky permissions problems, it's a good idea to check if you have it set: /usr/sbin/getenforce (or similar, depending on what system you are on).

See: http://www.crypt.gen.nz/selinux/disable_selinux.html for a good overview and how to turn it off (again, the details may vary depending on your OS/kernel version). If it's a test machine not publicly accessible, you can pretty safely turn it off, otherwise, you should read the site above to understand what it does. Most Linux package managers can install files to help you manage the policies for specific apps. On RH/CentOS, you can also use /usr/bin/system-config-securitylevel-tui to turn it on/off.
