Newbie - Troubleshooting after not being able to access UI

I finished the trial installation. Then I went to access the URL by going to http://management-server-address:8080/client, but only get Page Cannot be Found. I disabled the firewall, but still no luck. Any help would be appreciated. Thanks.

The web GUI runs inside a tomcat container and that process should be listening to port 8080. The first thing to do is to confirm this is the case by using netstat. You can run something like "netstat -n -l -p |grep 8080" and make sure there's a process called "java" which is binded to port TCP 8080. If that's not the case, you should look into the catalina.out log file for a clue as to why the tomcat server is running. It might be as simple as starting it, the service is called cloud-management and is found under init.d.

Erik,

Thanks for your response. With your help I started the Tomcat and Cloud Management services. Now I just get a blank page instead of Page Cannot be Found. Thanks for all of your help.

Hi Phil,

As you're getting a blank page, I would say checking catalina.out for clues woud be your next step. In my case, /var/log/cloud/management/catalina.out

Erik,
You are gold so far. Looking at the Catalina.out file I see

/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied
/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied
/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied
/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied
/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied

I'm not linux proficient as most and know enough to be dangerous. Would this involve Chmod command or something ? Sorry of the delay. I was forced to backburner this project for a little while. Thanks.

Hi Phil,

the file /usr/share/cloud/management/logs/catalina.out needs to be owned by the 'cloud' user and also the user must be able to write to the file. You need to use chown to change the file's ownership to 'cloud' and chmod allows you to make it writable.

Erik,

Thank you for all your help. I was eventually able to work it out. One folder was not allowing the write permission and I changed it. I am logged into the Cloud eval and going through the initial setup process. So far so good. Thanks again for your help. I really appreciate it.

I'm having the exact same problem. I get a blank white page at http://server:8080/client, in the catalina out log I get

/usr/sbin/tomcat6: line 30: /usr/share/cloud/management/logs/catalina.out: Permission denied

I'm not much of a Linux guy so detailed steps on how to resolve this would be awesome. Thanks.

Nevermind, rebooted the management server and it started working.

execute the below 2 steps in case anyone faces the similar problem

#cd /var/log/cloud/management/
#chmod 777 catalina.out
