Answer 1

assets folder should be writable by your web server process. Usually it is www-data if on apache configured by default. You can either add the user to the folder group with '+w' permission modifications

Alternatively just modify the permissions to 777 as assets folder will only contain your js and css files which will be exposed to the public anyway from your root directory

chmod 777 -R ./assets

You will also face the same issue with runtime and data/auth.php(if app is configured for using Yii auth roles), you can do similar suitable modifications there as well

UPDATE:: Additional Settings for PHP < 5.4 is required if safe-mode flags are set ( this was depreciated in 5.4 ) refer to http://php.net/manual/en/ini.sect.safe-mode.php on how to configure safe-mode settings in your php.ini file. Either you can set the flags fully off or exclude the directories in question. ( This step is not needed if you have added www-data(your web-process) to your group as the gid will then match automatically
