I have my a cluster Kloxo7. That 's great :D When i try adding slave it said "No socket connect to ...."
I disable firewall in slave and try again, it 's ok. You know, hosting cannot use without firewall. Please give me some port to open in firewall !
Thanks. Have a nice day :D

Port for Kloxo/Kloxo-MR is 7776-7778. Especially for master-slave connection need 7776.

Did you open 7776 in both side (master and slave)?.

Try open port 7770-7779 and then reboot servers.

I deleted one by one in that port range. Finally, 7777-tcp, 7778-tcp and 7779-tcp enough to work well after reboot. No need open 7776 port :D

Nice. Were you able to create database for a client that's assigned to a slave?
