This is preventing apache from performing a write action on something with an invalid context. You should check your tmpdir as it's defined in your php.ini, and possibly the mmcache and make sure apache the proper selinux context there (ls -Z). If apache is using /tmp as its temp directory (which is the default) then selinux will prevent apache from doing certain tasks with those files. It's best to create a tmpdir for apache in /var/www/tmp and define that in php.ini. This will fix tmp actions for apache. Details about this are here -> https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=193579 as for your normal files in the webroot, you should be sure they have the proper context on them. Files created in a user's homedir, and moved to the webroot will have an incorrect context. Files created in a user's homedir and COPIED will have a correct context. You can relabel the files as needed or use chcon in a similar fashion to chown and chmod. > /sbin/fixfiles restore This won't fix the problems because the context on them is 'correct' they're just in the wrong location. The simple way is to do something like chcon --reference=/var/www /your/files/here, or something to that effect. -- This message has been double ROT13 encoded for security.
