Subject Re: [users@httpd] find IP and PORT in use by Apache
Date Tue, 21 Jun 2016 18:54:34 GMT
You know, the problem is that compute nodes in Rocks distribution use Apache web server to
locate the install image. Currently, the compute node, says 
Unable to retrieve http://10.10.10.1/install/rocks-dist/x86_64/images/install.img The guys
on Rocks mailing list suggested that


the root of webserver tree is: /var/www/html the install subdirectory is soft-linked to /export/rocks/installif
the webserver can't find the install.img, then your distro is likely corrupted. To fix that
problem: # cd /export/rocks/install; rocks create distroIf you have somehow changed the configuration
of the webserver on your frontend, you need to figure out what was changed.



However, the soft link is present

The front end (the head node) has not been rebooted for more than 2 months, and I have some
how configured the httpd for some tests!
Now I see that something went wrong.
Do you have any idea?

Mahmood
