        And you can note here, I get the same FQDN message.

          Ah, now I have the problem. I just rebooted.

          So the problem is not that it updated. It is that it updated and something else changed that was not applied until a reboot applied the update. Like the new kernel.

                I didn't say the kernel broke anything. I said a new change that was not applied until reboot like the new kernel.

                  Ah I see.

                  I just rebooted some web servers last night and no issues.

                    And here is the problem. SELinux on the log file.

                    -- Unit httpd.service has begun starting up.
Mar 05 12:23:57 bookstack httpd[1046]: AH00558: httpd: Could not reliably determine the server's fully qualified domain name, usin

                    That vhost file that we made, bookstack.conf specified this: CustomLog /var/log/access.log combined

                    And the SELinux context is not writable by Apache.

                    [root@bookstack ~]# ls -laZ /var/log/access.log /var/log/httpd

                    It should have stated CustomLog /var/log/httpd/access_log combined

                      So, if you followed the original instructions, you can use this to fix it.

                      sed -i "s/access\.log/httpd\/access_log/" /etc/httpd/conf.d/bookstack.conf

                      Then start apache.

                      systemctl start httpd

                        FYI, I totally blame someone else and not myself as I used the conf file from @black3dynamite in my guide.

                        Not sure WTF changed to let it work then not work though.
