cybervolkan Posted January 19, 2009 Share Posted January 19, 2009 Hello, I am planning to setup a second server to actively backup my existing server (using round robin dns ). They will use same database in two diferrent locations. I have one problem (or question). Whmcs licenses are bound to an ip address. What about for my setup? Will I have to use a seperate license? Or is there a way to manage to run this setup? Thanks in advance 0 Quote Link to comment Share on other sites More sharing options...
bear Posted January 19, 2009 Share Posted January 19, 2009 Not sure if it will break license agreements or not (I'd guess it would), but if the failover would be just for a day or two while the main licensed server is broken or unavailable, it should still operate. How did you intend to keep the DB's in sync, replication? 0 Quote Link to comment Share on other sites More sharing options...
cybervolkan Posted January 19, 2009 Author Share Posted January 19, 2009 Thanks for reply, I have planned to setup a mysql replication configuration on both servers. For static files, I will try to use drdb. If It does not work, rsync will be the second choice. Drdb has worked nice in local lan but I don't know how it will work on two seperate datacenter. I have didn't tested but I has worked on paper But our main problem is licenses. Because, round robin dns is working like a load balancer. So half of requests will go to second server even if main server is up. This won't be a problem on this setup, but whmcs stops working as soon as it runs on a different ip address. I think I have to buy a seperate license. 0 Quote Link to comment Share on other sites More sharing options...
bear Posted January 19, 2009 Share Posted January 19, 2009 If It does not work, rsync will be the second choice. Rsync would be a poor choice to use on live data in a database, since the tables would not be locked, and any writes while copying could corrupt the results.

If it's for load balancing, then yes, a duplicate installation with license is needed. Have you opened a ticket with Matt yet to ask about possibilities? Mention what you're looking for, and I'm sure he can offer suggestions. 0 Quote Link to comment Share on other sites More sharing options...
eh-rob Posted January 23, 2009 Share Posted January 23, 2009 Rsync would be a poor choice to use on live data in a database, since the tables would not be locked, and any writes while copying could corrupt the results. I think he was talking about the static files. He was planning on doing replication on the database. 0 Quote Link to comment Share on other sites More sharing options...
bear Posted January 23, 2009 Share Posted January 23, 2009 Read the whole thread. He said rsync would be his second choice if replication didn't work out. I'd even quoted it from his post. 0 Quote Link to comment Share on other sites More sharing options...
mikelegg Posted July 13, 2011 Share Posted July 13, 2011 It would be handy if a WHMCS licence could be set to use one of two IP addresses (only one at a time) without having to manually change it. I have a similar failover system to the OP. 0 Quote Link to comment Share on other sites More sharing options...
