New Fog Server - /images location

[Technolust]

Team,

I am in the process of building a new fog server since the box we have already is out of storage.
I’m looking to use a different path instead of /images for security purposes. I would like the new location to be /fogserver/images. How can I do this?

Thanks,

Technolust

One of the questions the fog installer script asks you is image store location. The default is /images. Provide a different path there and the rest will be setup for you.

[george1421]

If you have not build the server yet, then lets discuss a few different options before it built.

[Technolust]

@george1421 Thank you George. I am at the point where I am ready to run the installer. I will make the change in the installer however, when there is an upgrade will the upgrade know the location?

Also what is the difference in the installer between Normal/Storage?

@Technolust said in New Fog Server - /images location:

Yes your answers to the questions are stored in a hidden file in /opt/fog/.fogsettings That file is referenced each time the installer is run, even between version upgrades.

Also what is the difference in the installer between Normal/Storage?

A “Normal” install is a traditional FOG server with webui. A Storage [node] is a deploy only server that has no web gui, a storage node must connect to a Normal mode FOG server to be functional. You would use storage nodes, maybe at remote locations so you can deploy images locally to target computers at the same site as the storage node.

[Technolust]

Awesome, Thanks George. Running through the installer now and just saw the installer explain the difference… Haha, Reading is fundamental…

Hey George,

The installer doesn’t ask you for a location it automatically chooses the install location.

What version of Linux would you like to run the installation for?

      1) Redhat Based Linux (Redhat, CentOS, Mageia)
      2) Debian Based Linux (Debian, Ubuntu, Kubuntu, Edubuntu)
      3) Arch Linux

Choice: [1]

FOG Server installation modes:
* Normal Server: (Choice N)
This is the typical installation type and
will install all FOG components for you on this
machine. Pick this option if you are unsure what to pick.

  * Storage Node: (Choice S)
      This install mode will only install the software required
      to make this server act as a node in a storage group

** Notice ** FOG is difficult to setup securely

SELinux and IPTables are usually asked to be disabled

There have been strides in adding capabilities

The recommendations would now be more appropriate

to set SELinux to permissive and to disable firewall for now.

@Technolust Well color me wrong. I’m pretty sure it use to…

If you look in the /opt/fog/.fogsettings file does it contain a field for /images?

We can manually fix it, but it would be swell if it retained the settings for the next install.

[Technolust]

@george1421 No worries man, should I just go ahead and go through with the install afterwords and see if we can change it? I will take an image of the server and revert back to it if I need revert back. I’m asking because I don’t have the /opt/fog directory configure yet because I canceled the install.

Thoughts?

[george1421]

@Technolust Well confirm that the… let me remote into my office and see if the field is there. Lets not do a bunch until we know. We can make it work like you need it. Give me a few minutes to double check things.

[george1421]

@Technolust OK I just looked and there IS the field in question. Its called storagelocation. Go ahead and do a normal install, let it default to /images

[george1421]

@george1421 Just open thoughts on changing storage location.

1. Update .fogsettings storagelocation field.
2. Update /etc/exports to from /images and /images/dev to new locations /fogserver/images and /fogserver/images/dev
3. Copy everything from /images to /fogserver/images
   cp -r -f /images/* /fogserver/images
4. Make sure directory permissions match between /images and /fogserver/images
5. In the web ui update Fog Settings->Fog Configuration Expand all settings and then search for /images and replace with proper path
6. Go to default storage node settings and update /images to /fogserver/images
7. Then back to the linux command prompt and rerun the fog installer script.
8. Double check /etc/exports to ensure that /fogserver/images is still shared.
9. Reboot the fog server
10. At the linux command prompt key in showmount -e 127.0.0.1. It should show /fogserver/images being exported after a reboot.

That should do it.

[Technolust]

@george1421 Ok George, so going ahead with the default install and then will try the settings below. Sound right?

[Technolust]

@george1421 Is it common to leave the mysql password blank?

@Technolust said:

No you better set a proper mysql root password before installing FOG. We are working on the installer to pilot people to set passwords.

[Technolust]

@Sebastian-Roth That’s what I figured. Thank you!!!

[Technolust]

@george1421 Hey George, in step 5, the Web GUI -> Fog Configuration -> Fog Settings -> Expand all -> there is no /images location. Should there be any specific settings? In step 6 do I also change the FTP path to /fogserver/images from /images? If so I did that as well. Finally step 10 - Looks good.
Export list for 127.0.0.1:
/fogserver/images/dev *
/fogserver/images *

Can you tell me if this will need to be performed for every update or will fog server updates keep these settings?

[Technolust]

Should the Storage Node show online?

When I go to storage nodes it is up and running.

Thoughts?

Thanks,

Technolust

Sorry I wrote that post from memory since I didn’t have immediate access to a fog console to verify.

also change the FTP path to /fogserver/images from /images?

Right you need to change everywhere you would see /images to the new images path.

It looks good for the export list.

If you updated the .fogsettings file in step 1 then no, it should be automatic moving forward.

[george1421]

@Technolust What does the content of the default storage node look like?

Also did you reboot the fog server after you made all of those changes? Some values are only loaded at boot time.
