Subject Re: connection of Agent to Management is continuously dropping
Date Mon, 15 Jun 2015 00:11:26 GMT
Hi Devender,

I've experience a similar issue a few times in my test environments, so i
took a closer look at what was causing it... If you're experiencing the
same issue, here's the symptoms, cause and resolution:

Symptoms:
- SSL fails to start on tomcat;
- SSL connection fails to establish between agent and management;

Diagnose:
Run:
file /etc/cloudstack/management/cloudmanagementserver.keystore
On a good setup should display:
/etc/cloudstack/management/cloudmanagementserver.keystore: Java KeyStore
On a bad setup should display:
/etc/cloudstack/management/cloudmanagementserver.keystore: data

Cause:
Management server has been setup to use encryption for configuration stored
in DB.
(This affects all fields marked as "Hidden" in the configuration table in
mysql)
DB Encryption secret is missing or wrong
in /etc/cloudstack/management/db.properties
(This happens when you uninstall and reinstall and db.properties gets
replaced with fresh one)

Resolution:
Option 1:
Restore a previous copy of your db.properties to decrypt configuration
values correctly and restart management server.
Option 2(only if you don't have a backup.... but you should ;) ):
Delete ssl.keystore from table, this will make server to create a fresh one
on restart.

On startup, server always creates a new instance of the keystore file,
based on what is read from the configuration table or creates and stores a
new one if none is there.

Let me know if this helps :)

Cheers,
Rafael
