<p>Hello,<br>
</p>
<p>Thank you for your advice!<br>
</p>
<p><br>
</p>
<p>Curl did not work on the master node.</p>
<p>It seems that nginx was not installed (service nginx status did not detect nginx).</p>
<p>I used yum to install nginx, but doing this seems arbitrary and does not seem to do anything (was it not supposed to be there in the first place?)</p>
<p><br>
</p>
<p>The bootstrap_admin_node logs suggested I use "<span>fuel-bootstrap build --activate</span>" once I had fixed the network.</p>
<p>This command crashes on a Cobbler issue (first image).</p>
<p>The configuration file of Cobbler has a comment suggesting I restart the cobbler demon. (second image)<br>
</p>
<p>The command still fails after restarting the demon.</p>
<p>This is the point where I begin to suspect httpd (apache) is in cause.</p>
<p>When I restart httpd, I get a strange error explaining how there is a name duplication in the Cobbler configuration file inside the /etc/httpd folders. (two last images) Specifically:</p>
<p><br>
</p>
<p></p>
<div>> # Use separate process group for wsgi<br>
> WSGISocketPrefix /var/run/wsgi<br>
> WSGIScriptAlias /cobbler_web /usr/share/cobbler/web/cobbler.wsgi<br>
> WSGIDaemonProcess cobbler_web display-name=%{GROUP} /// <span>***This line***</span><br>
> WSGIProcessGroup cobbler_web<br>
> WSGIPassAuthorization On<br>
</div>
<p></p>
<p><br>
</p>
<p>At this point, I am rather clueless and am starting to wonder if I am not breaking the OS further by stabbing in the dark. I wonder if this is leading anywhere, or whether I should just restart the Fuel installation from the CentOS image...</p>

<div dir="ltr">Hi,
<div><br>
</div>
<div>Try to access UI using "curl" from your machine and from Fuel Master:</div>
<div>1. If it's not available from your machine but available from Fuel Master, make sure that your network is configured correctly use regular troubleshooting techniques for that ping/traceroute/tcpdump.</div>
<div>2. If it's not available from both, your machine and Fuel Master, verify that Nginx up and running and that it's configured correctly, there could be problems with installation see "/var/log/puppet/bootstrap_admin_node.log" for details.</div>
<div><br>
</div>
<div>Thanks,</div>

<p>Hello,</p>
<p><br>
</p>
<p>I have attempted installing Fuel on my IBM server for testing purposes. </p>
<p>I currently find myself in a similar situation as the one described in this Openstack ask post: <a href="https://ask.openstack.org/en/question/84510/fuel-ui-network-error/" class="m_542873910897628344OWAAutoLink" id="m_542873910897628344LPlnk265578" target="_blank">https://ask.openstack.<wbr>org/en/question/84510/fuel-ui-<wbr>network-error/</a></p>
<p><br>
</p>
<p>I can ping to and from the server, and when I try to connect to the UI from my web browser, the page does not load. The browser tells me I might have too stringent security requirements, but this does not seem to be the issue (deactivating the firewall does
not change anything).</p>
<p><br>
</p>
<p>I cannot restart the Nailgun server simply because the dockerctl commands are deprecated on my version, and I have not found anywhere the commands that are meant to replace it.</p>
<p>fuel-utils reveals no issues with Nailgun, but apparently something is off with Cobbler (that's probably not relevant though).</p>
<p><br>
</p>
<p>When I check for the availability of the Nailgun server, I am told "Can't connect to Nailgun server! Please modify "SERVER_ADDRESS" and "LISTEN_PORT""</p>
<p><br>
</p>
<p>My config.yaml file looks like this:</p>
<p><br>
</p>
<p></p>
<div>SERVER_ADDRESS:"10.12.99.34"</div>
<div>LISTEN_PORT:"8000"</div>
<div>SERVER_PORT:"8443"</div>
<div>KEYSTONE_USER:"...............<wbr>."</div>
<div>KEYSTONE_PASS:"...............<wbr>."</div>
<div>KEYSTONE_PORT:"5000"</div>
<div><br>
</div>
<div>The IP is the host's IP as well as that advertised on the fuel console launch; 8443 is the advertised port for login as well.</div>
<div><br>
</div>
<div>I have added some of the following rules to the host's firewall, more or less blindly following tutorials:</div>
<div><br>
</div>
<div>
<div>*filter</div>
<div>:INPUT DROP [0:0]</div>
<div>:FORWARD DROP [0:0]</div>
<div>:OUTPUT ACCEPT [243:14376]</div>
<div>:ext-filter-forward - [0:0]</div>
<div>:ext-filter-input - [0:0]</div>
<div>-A INPUT -i lo -m comment --comment "000 allow loopback" -j ACCEPT</div>
<div>-A INPUT -p tcp -m state --state NEW --dport 23 -j ACCEPT</div>
<div>-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT</div>
<div>-A INPUT -m state --state NEW -m tcp -p tcp --dport 8000 -j ACCEPT</div>
<div>-A INPUT -s <a href="http://10.12.99.0/24" target="_blank">10.12.99.0/24</a> -p tcp -m multiport --dports 22 -m comment --comment "010 ssh" -m state --state NEW -j ACCEPT</div>
<div><br>
</div>
<div>I do "service iptable restart" and I restart firewalld after modifying this file.</div>
<div>I restart the network before trying to access the fuel UI.</div>
<div>I do all of my modifications on my client machine, on PuTTy using Telnet.</div>
<br>
</div>
<div>I've been stuck on this issue and have been on the lookout for support, hence my joining this email list.</div>
<div>This is not the only issue I've run into, but that's the most pressing one right now.</div>
<div>I know that I am attempting to join the right site on the browser because the tab icon on Chrome changes to the Fuel icon.</div>
<br>
<p></p>
<p>Regards,</p>
<p>Vincent</p>
