Hello, Thanks for the great howto - How To Set Up A Load-Balanced MySQL Cluster. We completed it almost succesfully, but... We got an error on our (active) loadb1 server. The error is: DBI connect('database=ldirectordb;host=10.10.20.11;port=3306','ldirector',...) failed: Can't connect to MySQL server on '10.10.20.11' (110) at /etc/ha.d/resource.d/ldirectord line 1950 and DBI connect('database=ldirectordb;host=10.10.20.12;port=3306','ldirector',...) failed: Can't connect to MySQL server on '10.10.20.12' (110) at /etc/ha.d/resource.d/ldirectord line 1950 We've set up everything as told in the howto. Does anyone have any idea what this error could mean and how it is need to be solved? Our setup is the following: loadb1 : 10.10.20.1 (We called it x1clmng) loadb2 : 10.20.20.2 (We called it x2clmng) sql1 : 10.10.20.11 (We called it x1mysql) sql2 : 10.10.20.12 (We called it x2clmng) virtual ip sql : 10.10.20.10
Hello! /etc/ha.d/haresources gives: x1clmng \ ldirectord::ldirectord.cf \ LVSSyncDaemonSwap::master \ IPaddr2::10.10.20.10/24/eth0/10.10.20.255 And syslog writes no errors at all..
Try this instead: Code: x1clmng \ ldirectord::ldirectord.cf \ LVSSyncDaemonSwap::master \ IPaddr2::10.10.20.10/8/eth0/10.255.255.255
Falko, Thanks for the reply. We will try and see what happends. We use an Debian Sarge template in a XenSource environment. Is it possible that we miss some crucial packages that aren't installed in the template? Do you have any idea which packages are needed for Ultramonkey and the Cluster? I could send you a list of installed packages on our system, maybe that you see something missing... We hope to hear from you soon! Greetz
All needed packages are mentioned in the tutorial, so the packages should be present on your systems.
Hello, We've changed the subnet to 8 as you said and till now we don't have any problems at all, so we hope that it's the right solution! Thanks again!
