Hi Aniket, Is MySQL listening on the IPV6 loopback interface ::1? See below for the connection test on a freshly installed CentOS 6.3 with MySQL. It fails on the V6 loopback.
Fix could be to either bind MySQL to ::1 or to remove the V6 loopback entry in /etc/hosts. Hth. [root@db01 ~]# telnet ::1 mysql Trying ::1... telnet: connect to address ::1: Connection refused [root@db01 ~]# telnet 127.0.0.1 mysql Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 8 5.1.66-log?<!.c,M~vk6i1U:`Ug+: ^] telnet> Connection closed.

I'll try removing that and will try restoring db.properties file's IP entries as before. But why IPv6 entry in hosts file will cause this issue?

But I figured it out. I changed db.properties and changed all "localhost" and "127.0.0.1" with actual management server IP. Management server and DB are on same node but seems somehow mysql was blocking connections accessed with above two and was allowing by actual IP. It is working fine now and I launched my first instance too! Looks cool so far. Thanks for pointers anyways. Problem was in exactly the same area. Does your /etc/hosts line have an IPV6 entry for localhost??
