[OpenSIPS-Users] Help!! How to do failover of mysql connection

[Matteo D'Amato]

With SRV, if one box is down will it still get hit or does the DNS only send
to the one that is up?

That will not work. Try DNS SRV. Take a look at this link

Hope it helps.

Hi,

is it fine if I use DSN resolver?
Let me explain in detail:
I setup a DSN resolver & add A record for mysql servers.
mysql         A          192.168.1.5
mysql         A          192.168.1.6

where 192.168.1.5 & 192.168.1.6 are mysql cluster nodes.

So mysql.somedomain.com will point to both servers.
It will do load balance & failover both.

Please confirm that it will not create any issue.

Thanks,
Krunal Patel

This problem has been solved many times.  The absolute most bomb-proof
MySQL failover solution involves a combination of DRBD  and Linux HA
(Heart Beat).  The replication model has too many issues IMO.
