Private key path not found when registering client

[A Former User]

Hi,

I created a freshly installed CentOS7 host and I installed fogproject on it.

The installer runs fine and I can log in into Fog.
When I install the client on the first computer and try to register this computer in for, the registration fails and the client does not want to do anything like power management or execute a snapin.

In the logs of the client I get the following errors:

This continues on an on.

Reading previous posts I check the rights of the key, but that seems to be OK.

SELinux has bee turned off.

I tried running installfog.sh -KY, the installer runs and ends fine, but it doesn’t solve my issue.

What can be wrong and where can I look?

Thanks in advance!

@Jurgen-Goedbloed said in Private key path not found when registering client:

Private key path not found

Please take a look at the storage node definition/settings in the web UI. There is an option called SSL path. Make sure this matches exactly what you have in the filesystem - /opt/fog/snapins/ssl as we see.

Hi Sebastian,

Thanks for the answer.
This was indeed the root cause.
On our Linux servers we set the umask to 0027 instead of 0022.
That has the consequence that /opt/fog did not have access permissions for the apache user as the R and X for others missed. Maybe an improvement for the installer as the other directories under /opt/fog have their rights set explicitely by the installer?

@Jurgen-Goedbloed I am not exactly sure I get what you say. Has the SSL path option been wrong? What was it set to? Is this something the installer messed up?

Or do you mean the permissions were causing this issue? I have not messed with umask in a long time but I do remember this can cause quite some unexpected situations. I can imagine this could also cause trouble in other places where the FOG installer does not explicitly set permissions.
