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 On Fri, Jun 12, 2015 at 1:23 PM, Devender Singh <dev1986en...@gmail.com> wrote: > After upgrading cloudstack 4.2.1 to 4.4.2 we are facing console proxy agent > issue . > > connection of Agent to Management is continuously dropping > > netstat -na | grep 8250 > > > > tcp 867 0 x.x.x.x:37789 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:38275 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 .x.x.x:37942 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x3:38327 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:37810 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:37737 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:37775 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:37858 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:38039 y.y.y.y:8250 CLOSE_WAIT > > tcp 867 0 x.x.x.x:37960 y.y.y.y:8250 CLOSE_WAIT >
