CentOS 7/RHEL 7/Fedora 20 Support

If you all know what needs to be changed/corrected for, place it here and I’ll try making the changes to make your lives that little bit easier.

I think for centos 7 mysql needs to be mariadb instead.
-
Bump!
I followed the steps here to install Mariadb and secure it (leaving blank password of course):
…but the fog installer still complains about mysql not starting… file not found… so I was able to get a little farther on the install process…
-
Ok
I was able to install FOG 1.2.0 on CentOS 7…
[LIST=1]
[]Install CentOS 7 Desktop using Gnome Desktop
[LIST=1]
[]Added most options except backup client and one other one… (can’t remember which one)
[/LIST]
[]Installed MariaDB by:
[LIST=1]
[]sudo yum install mariadb-server mariadb
[]sudo systemctl start mariadb
[]sudo mysql_secure_installation
[LIST=1]
[]Left root password blank, but did remove annonymous access (not sure this is completely OK…)
[]Removed remote root access
[/LIST]
[]sudo systemctl enable mariadb.service
[/LIST]
[]Edited the script for the FOG Install in …/fog_1.2.0/lib/redhat/functions.sh
[][INDENT][LIST]
[]section for configureMySql()
[]commented out exit 1; by adding a “#” in front so it looks like this:
[LIST]
[]#exit 1;
[/LIST]
[/LIST][/INDENT]
[*]Ran the FOG install script
[/LIST]
Tada!!!Note 1: I just finished this install a couple of minutes ago before making this post… I still have to test it…
Note 2: I am rather new to this, so use at your own risk…Good luck.

I had to also disable SELINUX:
[COLOR=#000000][FONT=monospace]sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/sysconfig/selinux
sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/selinux/config[/FONT][/COLOR]And clients were able to PXE boot after that.
I can register hosts… but, on Upload task the client can’t mount NFS:
[CODE]mounting x.x.x.x:/images/dev/ on /images failed: Operation not supported
Fatal Error: Failed to mount NFS Volume[/CODE]
Then I chown the /images forlder:
[CODE]chown -R fog /images[/CODE]
And rebooted and tried again, same error…

I just got back from vacation. Fog installer takes care of this already for these distros.

Have to disable SElinux on all distros. Rip off your firewall as well quick to test the NFS mount. systemctl stop firewalld.service && systemctl disable firewalld.service
-
Has anyone been able to get a succesful upload working? Mine is failing on FOGFTP_login() have tried a few quick fixes, will look into it some more this afternoon.

Yup… I forgot to add that I did have to stop and disable the firewall service…
The problem I was having with mounting the NFS share for /images/dev in /images was due to the NFS service not running…
I did, I think, systemctl restart nfs-server.service and also systemctl enable nfs-server.service just to be sure…

Is it working now? I don’t think your error is centOS 7 specific. I am almost positive I had nfs mounting out of box in centOS 7.

I got upload working on my CentOS 7 machine. Might have been due to setting seccomp=No in /etc/vsftpd/vsftpd.conf or more likely due to stupid vlan issues being resolved. Testing Multicast now, it seems to hang on “starting to restore image”
-
Multicast still not working
Output of Multicast.log:
[08-15-14 1:16:20 pm] | StorageNode Not found on this system.
[08-15-14 1:16:30 pm] | StorageNode Not found on this system.
…
This is a stand alone fog server, it is the master storage node. I’m kind of out ideas.Also I can use udp-sender and receiver to transmit the multicast log simultaneously between two clients as per these instructions. The third step is out of date.

madskillz23,
Same here… can’t multicast even on a flat (unmanaged) switch…
now… on a VM Server (different than the one with the problem for multicast) MariaDB fails to start on boot and I have to restart it every time with:
[INDENT=1]systemctl restart mariadb.service[/INDENT]
I tried adding the following two lines to the my.cnf
[INDENT=1][mysql.service][/INDENT]
[INDENT=1]–service-startup-timeout=9000[/INDENT]but it did not help…
Again… I’m semi-new to linux… any help appreciated…

Not sure on multicast yet. Try systemctl enable mariadb.service. and on an unrelated note, I also had to start the nfs service on a new server I threw up, like you had happen to you earlier in the thread
-
madskillz23,
I fixed the mariadb problem by:
[INDENT=1]su[/INDENT]
[INDENT=1]gedit /etc/rc.d/rc.local[/INDENT]Adding this line to the end of file “rc.local”
[INDENT=1]systemctl restart mariadb.service[/INDENT]then as the comments at the beginning of “rc.local” indicated to make sure the file is executable, ran:
[INDENT=1]chmod +x /etc/rc.d/rc.local[/INDENT]
[INDENT=1] [/INDENT]
Now, on to figuring out about the multicast…EDIT: I did run the command to enable the mariadb.service and it kept on crashing on boot…

On CentOS 7 across multiple servers I repeatedly keep getting this same problem:
On original fresh fog install, does not ask to update database schema. But after a while (few hours to a weekend) it prompts for a database schema update which consistently fails. Have to rerun fog installer to bypass the issue so I can get to the web interface. Is there a way to manually reset that bit in the database without rerunning the fog installer?
Have not seen this issue on CentOS 6.
-
doesn’t the fog installer re-launch the database??? if so, would a cron job to restart it nightly or every other night be an OK workaround??
systemctl restart mariadb.service
-
The correct command for nfs starting after a reboot is: [CODE]systemctl enable nfs-server.service[/CODE] Apparently just nfs instead of nfs-server didn’t work.

Nope restarting the system has no effect. Its a bit in the database or somewhere that is persistently set to upgrade.
-
Can FOG issue an error on the page that the database is NOT running rather than to say the schema is out of whack?? That would make troubleshooting a bit easier…
Something like, Can’t connect to database, please restart it or check on it?
