I've been bashing my head into a wall the past few days on this. I am trying to setup a Load Balanced MySQL Cluster. I can get the MySQL NDB Clusters working, but when I try to install the HA Load Balancers, I can't get past the step of the shared Virtual IP. I'm basing my sequence on HowToForge Guide written for Debain (http://www.howtoforge.com/loadbalanced_mysql_cluster_debian_p7). I've added my own tweaks and use the appropriate CentOS x64 commands and configurations. I am creating a loopback interface with the following configs: vi /etc/sysconfig/network-scripts/ifcfg-lo:0 DEVICE=lo:0 IPADDR=10.98.51.10 NETMASK=255.255.254.0 NETWORK=10.98.50.0 # If you're having problems with gated making 127.0.0.0/8 a martian, # you can change this to something else (255.255.255.255, for example) BROADCAST=10.98.51.255 ONBOOT=yes NAME=loopback The Guide shows this for Debian vi /etc/network/interfaces auto lo:0 iface lo:0 inet static address 192.168.0.105 netmask 255.255.255.255 pre-up sysctl -p > /dev/null I think I am almost there, but just can't place my figure on my error. Can anyone help guide me? -------------- next part -------------- An HTML attachment was scrubbed...
