Objectif
On a deux machines A et B.
Ces machines sont "identiques" !
La mise en place
Environnement
Scripts indispensables
/etc/sysconfig/carp/vip-down
#!/bin/sh exec /sbin/ifconfig $1 down
/etc/sysconfig/carp/vip-up
#!/bin/sh
# We could use ifup directly, but it complains if the address is already used
. /etc/sysconfig/network-scripts/ifcfg-$1
exec /sbin/ifconfig $1 ${IPADDR} netmask ${NETMASK} up
Sur le Master
/etc/sysconfig/carp/vip-100.conf
