Hi,

Installed Scalr from github and followed the tutorial http://wiki.scalr.net/display/docs/Install+a+Wordpress+Blog+with+Scalr

Scalr is able to provision VM for loadbalancer, apache and mysql. However the scalr dashboard continued to show that server is pending . AWS console showed that VM are created and running. I logged into the apache VM and found that monitoring tool scalarizer service failed to start.

I created the VM as shown in the tutorial (Ubuntu 10.4) type is t1.micro in AWS EC2. The console log of the VM is at http://pastebin.com/PGswAjnG

Any help to troubleshoot this issue will be greatly appreciated.

Regards,

Senthil

Scalarizr agent on VM is unable to communicate with you Scalr instance. On the VM check /var/log/scalarizr.log. Make sure you have set the correct IP address in Scalr settings and reqd ports are open.

Thanks. Further probing, it appears that scalarizr is not starting due to parse error . Stack trace (/var/log/scalarizr.log) is here. http://pastebin.com/vQNLbxnT

Any help from Scalr team is greatly appreciated.

I would recommend to do this privately, as it may contain personal information.

Hi,

I traced the problem to be not able to communicate with Scalr server. When the VM is created in AWS, the scalrizer is configured to look up http://example.com/query-env to load parameters.

As a hack, i changed /etc/hosts file to resolve example.com to scalr server, pushed new virtual host "example.com" , copied environment.php (at the www directory) into query-env/index.php.

It started working. Does anyone know, how to pass the actual scalr server hostname instead of example.com?

Regards,

Senthil
