phpfog Application runtime path is not valid - yii

Question

I'm trying to implement a little default application that comes with yii framework on phpfog.
I've installed it according to the instructions using GIT. Now, when I try to run it, I get this error (below).
I've checked to make sure that the directory is writeable and that the directory called for does exists. I'm stuck, what do I do next?
Application runtime path /var/fog/apps/app35423/austintxous.phpfogapp.com/demos/emp/protected/runtime" is not valid.
Please make sure it is a directory writable by the Web server process.
259 return $this->_runtimePath;
260 }
261 }
262
263 /**
264 * Sets the directory that stores runtime files.
265 * #param string $path the directory that stores runtime files.
266 * #throws CException if the directory does not exist or is not writable
267 */
268 public function setRuntimePath($path)
269 {
270 if(($runtimePath=realpath($path))===false || !is_dir($runtimePath) ||
!is_writable($runtimePath))
271 throw new CException(Yii::t('yii','Application runtime path "{path}" is
not valid. Please make sure it is a directory writable by the Web server process.',
272 array('{path}'=>$path)));
273 $this->_runtimePath=$runtimePath;
274 }
275
276 /**
277 * Returns the root directory that holds all third-party extensions.
278 * #return string the directory that contains all extensions. Defaults to the
'extensions' directory under 'protected'.
279 */
280 public function getExtensionPath()
281 {
282 return Yii::getPathOfAlias('ext');
283 }

Answer 1

The web server cannot write to the runtime directory. Make sure it exists, and change ownership of it to your web server, or set chmod 777 (which is a fine solution if it's your dev environment).
cd [project directory]
chmod 777 protected/runtime

Answer 2

Have you got a firewall running?
Maybe it's preventing write access?

Answer 3

you must config with semanage like this which allow php-fpm write access to directory
# semanage fcontext -a -t httpd_sys_rw_content_t 'YOUR_PATH_HERE'
# restorecon -v 'YOUR_PATH_HERE'
