Redhat Cluster updating kernel setting
hello,
I was going through clustering documentation for Redhat, it says "Enable IP Aliasing support in the kernel by setting the CONFIG_IP_ALIAS kernel option to y. When specifying kernel options, under Networking Options, select IP aliasing support", I knew I should update /etc/sysctl.conf with CONFIG_IP_ALIAS = y, the confusing part is When specifying kernel options, under Networking Options, select IP aliasing support" where do I have to change these setting
Thanks,
