Can't access scalr-ser

[Karima Kaddouri]

Hello,

This is the first time I am trying Scalr. I am following the steps for the open source version. After installing scalr-server and finishing its setup, I can't access scalr to login as admin.

When I run "nestat -nlp" port 80 is not listening on 0.0.0.0. How can I solve this.

Also, what is my.scalr.com and how do we get credentials to have access to it ?

Thank you!

Did you run "scalr-server-ctl reconfigur"? If you did, did you see any errors? If you're unsure, re-run it. 

my.scalr.com is a hosted version of Scalr. You can learn more and / or sign up for a trial here: http://www.scalr.com/pricing/hosted

Hi, 

I ran  "scalr-server-ctl reconfigure" and I got an error "Error executing action 'start' on resource 'supervisor_service[httpd]', followed by the error trace.

Best,

Karima

Please post the trace; that's the helpful bit that'll clue somebody into what's going wrong :).

Thanks for pitching in, Karl!

This means Apache was unable to start (and therefore explains why nothing is listening on port 80).

You should review the logs under /opt/scalr-server/var/log/httpd and /opt/scalr-server/var/log/supervisor/httpd.err, and look for errors there.

Feel free to post the logs here if you can't find the root cause yourself.

Thank you so much for your input guys !

I tried to find the root of the error from the trace but I couldn't, so I am posting it here hoping someone could.

Hi,

Like I asked a bit earlier, please include the Apache log files.

The trace only indicate Apache couldn't start. The log files will indicate why.

Hi!

I managed to fix the issue after some research :) ! thank you for your help and your time everyone !

Cheers,

Karima

What OS are you running this on? Is it a clean server or do you run other things as well?

It might be that you have something else blocking port 80. When you did the "netstat -nlp", did you see port 80 being used at all? Maybe listening on 127.0.0.1?

Regards,

Daniele

Hey there,

Please disregard the last message here from Daniele, it was stuck in moderation and I just let it through (and therefore it's a bit outdated). 

Sorry about the inconvenience,

Cheers,
