@Wayne-Workman What happens if you run:

apachectl restart

[Wayne Workman]

changed ownership and permissions of the /opt/fog folder

chown -R apache:apache /opt/fog
chmod -R 744 /opt/fog

systemctl restart httpd

@Tom-Elliott
apachectl restart

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

[Wayne Workman]

So - what I have done is - I built a new fog server, moved over the images, installed the SELinux policy and firewalld settings,

and copied over the /opt/fog directory.

The server has a different name - but the same IP.

[Tom Elliott]

Then is it possible selinux is failing to allow creation of the /opt/fog/snapins/ssl/.srvprivate.key file?

My guess is either this file is not present, or it is empty.

[Wayne Workman]

@Tom-Elliott I think it’s there… I copied the whole directory from the old server.

ls -lat /opt/fog/snapins/ssl

total 8
drwxr--r--. 4 apache apache   50 Nov 24 11:05 ..
-rwxr--r--. 1 apache apache 3243 Nov 24 11:04 .srvprivate.key
drwxr--r--. 2 apache apache   44 Nov 24 11:04 .
-rwxr--r--. 1 apache apache 1586 Nov 24 11:04 fog.csr

[Tom Elliott]

what if you run:

setenforce 0; systemctl restart httpd

[Wayne Workman]

@Tom-Elliott Funny you asked, I was trying it as you replied.

it works.

OK Done, FOG Server successfully migrated to Fedora 23 with Firewalld enabled.

I’ll set SELinux back to enforcing just to try it out - but the problem described in this thread does need some addressing.

I’m more than willing to help ofcourse.

[Wayne Workman]

@Jbob Fedora 23.

ls /etc/selinux/targeted/modules/active/modules/ | grep fog

ls: cannot access /etc/selinux/targeted/modules/active/modules/: No such file or directory

[Wayne Workman]

@Jbob SELinux also apparently breaks the FTP Image Size feature.

fog

[Wayne Workman]

@Jbob Figured it out.

The newest SELinux userspace project release 2015-02-02 includes a change of the location of the SELinux policy store, which defaults to /var/lib/selinux/.

https://fedoraproject.org/wiki/Changes/SELinuxPolicyStoreMigration

find /var/lib/selinux | grep fog

/var/lib/selinux/targeted/active/modules/400/fog
/var/lib/selinux/targeted/active/modules/400/fog/lang_ext
/var/lib/selinux/targeted/active/modules/400/fog/hll
/var/lib/selinux/targeted/active/modules/400/fog/cil

[Wayne Workman]

@Jbob Whenever you’re free just let me know. I have FOG setup in Fedora 23 both at work and home.

[Tom Elliott]

Another thread being solved because this isn’t “directly” a FOG issue, but rather SELinux issue.
