CentOS 7/RHEL 7/Fedora 20 Support
-
So I no longer think Multicast not working on CentOS 7 is related to a database issue. Tested by importing a functional Centos 6.5 Fog 1.2 database to the CentOS 7 install of fog and updating the users privileges. Anybody got any ideas?
-
Any update with CentOS 7 and Multicast issue? I managed to have a functional fog server (as far as tested) except Multicasting (“StorageNode Not found on this system”).

To get multicast working on CentOS7 you’ll need to modify the following line in function getIPAddress in /var/www/html/fog/lib/fog/FOGCore.class.php
from:
[CODE]exec(“/sbin/ifconfig | grep ‘[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}’| cut -d’:’ -f 2 | cut -d’ ’ -f1”, $arR, $retVal);[/CODE]to:
[CODE]exec(“/sbin/ip addr | grep -o ‘[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}/[0-9]{1,2}’ | cut -d/ -f1”, $arR, $retVal);[/CODE]If you have multiple interfaces with IP addresses you might need to use the following in the first portion of that line
[CODE]/sbin/ip addr list eth0[/CODE]
Replace eth0 with the interface you use for fog.
I haven’t tested this with Ubuntu but if the system has iproute2 package installed it should work.

Thanks a lot vinyard, it works smoothly now

Good work guys. Here is the info you posted. I just rehashed it into the wiki.
[url]http://fogproject.org/wiki/index.php/Installation_on_CentOS_7#Multi-Cast_Issues[/url] -
Hey all,
Just wanted to let you know I’ve “baked” some of the found items in here into the installer and system. FOGCore will check ip’s from ifconfig, if nothing is found will attempt with ip addr. The installer should take into account the systemd inclusion on CentOS/Redhat 7 now as well.

On this subject, I’ve successfully installed FOG on a vm(CentOS 7) and have had some trouble throughout. I used MariaDB for the database and was able to get a registration menu. However, when I go to upload my first image, I get this error:
*Mounting File System…mount: mounting <ip address>/images/dev on /images failed: Operation not supported
Done
*Preparing to send image file to server.
*Checking mounted File System…
#############################################an error has been detected!
############################################
Fatal Error: Failed to mount NFS volume
I do have .mntcheck files in each the /images and /images/dev dirs and am trying to use the FOG server as the storage server as well. Any ideas on what to check? I’ve googled and gone through forums but any direction will help greatly!

Hi,
Did you check the right of each folder ?
Regards,
Ch3i. -
Also, have you ensured firewall and selinux are disabled?

Thanks for checking in, Tom and ch3i.
I am using iptables and selinux because we must with our environment.
FOG Version: 1.2.0
OS version CentOS 7There are no log messages in the apache error log around the time I try to upload the images from the client machine. I am going through the wiki now but I think it’s an issue with FOG trying to mount /images and /images/dev. I’m new to FOG so please be gentle. Oh, here are the perms/ownership on /images and /images/dev:
stat /images
File: ‘/images’
Size: 4096 Blocks: 8 IO Block: 4096 directory

First make sure nfs is actually running with [code]service rpcbind restart; service nfs restart[/code]
If iptables is blocking the ports nfs uses you may have to figure out which are in use and unblock them from iptables.
-
Is the nfs-server running? What is the output of the following?
[CODE]systemctl status nfs-server[/CODE]
If it is not running, run the following:
[CODE]systemctl enable nfs-server
systemctl start nfs-server[/CODE]You should test this with iptables and selinux disabled first to make sure everything works as expected.
-
That did work!! Hallelujah! Thanks vinyard and Tom!! I ran the following commands and now its uploading that first image:
systemctl status nfs-server
systemctl enable nfs-server
systemctl start nfs-serverThanks guys, success at last!
