No more web GUI after upgrade to 6.2.0

It's a symbolic link.

ls -al 090-jenkins.conf
lrwxrwxrwx 1 root root   23 Nov 24 22:59 090-jenkins.conf -> /apps/jenkins/http.conf

So I did this:

cd /apps/jenkins
 mv http.conf http.conf.old

systemctl restart apache2

(no ouput on screen, indicating it started)

Now I can enter the admin web GUI again!

What is the impact of the changes we made?
Can I now uninstall Jenkins (I'm not using it anyway)?

Interesting those two config files had different ports specified. That could be part of the problem.

I see.

http://localhost:8443/jenkins

vs

http://localhost:8180/jenkins

But then one is for https and the other one is for http, so shouldn't there be different port numbers?

You moved the Jenkins apache conf so it wasn't loaded.

Yes you should be able to uninstall it.

Ah. http vs https would explain that

Thanks for your help!

Remaining issues:

1. Jenkins doesn't uninstall


2. Cannot enable SSI and and virtual host any more (https://www.readynas.com/forum/viewtopic.php?f=36&t=73204#p408144), since the apache config has changed significantly.


Found a way to enable the SSI. Will create a post on that later for 6.2.0.

Can you remove it via SSH?

dpkg -l | grep jenkins
apt-get remove jenkins
apt-get purge jenkins
rm -rf /apps/jenkins

dpkg -l | grep jenkins

ii  jenkins                         1.534.0                        all          Continuous integration system written in Java

The remove is complaining about missing dependencies.

apt-get remove jenkins

Ah, I guess if you don't need to remove Jenkins there's not much harm leaving it there.

I guess not, but I don't like leaving unstable apps on my NAS. The rm -rf got the directory cleaned out and also made the Jenkins logo move from Installed Apps back to Available Apps.

rm -rf /apps/jenkins

In the mean time, a newer version of Jenkins became available (1.534.1) and I managed to install it and now the launch page shows up. So that's solved now too.

Thanks guys, I had the same problem with not accessing web ui after upgrade to 6.2.2 on my ReadyNas 104. I did:

rm /etc/apache2/sites-enabled
systemctl restart apache2

and got back online.

However, I need jenkins so I reverted that and just:

a2enmod proxy
service apache2 restart

which got me online with jenkins. Doing and upgrade just now of all my plugins so maybe the Jenkins thingy is fixed…

Cheers,
Viktor
instead which will make that command w
