Hmm. You know, I hope, that the 777 permission is bad...the file only needs to be world readable:
Code:
-rw-r--r--. 1 root root 2018 Oct 24 2017 phpMyAdmin.conf
on my system.
But that's not the problem in any case.
Presumably, this is also true
Code:
drwxr-xr-x. 3 root root 4096 Dec 3 12:43 /etc/httpd/conf.d
drwxr-xr-x. 5 root root 86 Dec 3 12:35 /etc/httpd/
Have you edited the file? If so, how?
Linux intentionally throws "Permission denied" errors when there may be other problems, as if the file contains DOS line end characters.
