[dcphp-dev] Re: Question On "Permission denied"

Hi Robyn,

Here are couple questions/suggestions to help you:

What is the user that Apache is running as?

If you want to become root and have sudo permission run  "sudo su -" and you'll become root.  Don't stay here long though.

Once there - if you want to test to see if selinux is bothering things run :  # echo 0 > /selinux/enforce

to disable selinux temporarily - you can echo 1 to the same to re-enable it later.

Check if this solves your problem.  If it does, then re-enable (actually re-enable in either case) and try opening and changing  the following file

/etc/selinux/config. You need to change the SELINUX option to permissive like so:

SELINUX=permissive

which will cause selinux to not interfere, but log what it would have complained about to the logs.

If that doesn't solve it - I'll need an answer to the user who apache is running as..

Hey folks, 

I have a problem. I have a LAMP server running CentOS. In php I am attempting to opendir('/var/lib/mysql/');

But I am getting a "Permission denied" error.

drwxr-xr-x. 2 root root 4096 Apr 23 12:52 mysql

I can opendir('/var/'), and opendir('/var/lib/') but not opendir('/var/lib/mysql/');.

I can opendir on other directories in /var/lib, (like /var/lib/php). 

The permissions are set 755 for each level in this tree.

They are all owned by root:root, EXCEPT for /var/lib/mysql, which is owned by mysql:mysql.

I set the owner to root:root - but nothing. 

This is a test environment, so I set all the tree to 777 - nothing. 

I thought is could be the dot at the end of the permissions, which I read means the file has an access list with SELinux. But I cannot alter that. 

So, I'm a bit stumped. I don't have root user, but I do have sudo. 

Any suggestions?

Thanks in advance.
