This module installs and configures ucarp on CentOS 7.
It allows you set up multiple virtual ip addresses with automatic failover by using ucarp.
puppet module install yoshz-ucarp
Add the module to node configuration:
node /host*/ {
class { '::ucarp':
bind_interface => 'ens160',
password => 'ProtectedPassword',
}
ucarp::host { '001':
bind_interface => 'ens160',
vip_address => '192.168.0.101',
source_address => '192.168.0.1',
master_hostname => 'host001',
}
ucarp::host { '002':
bind_interface => 'ens160',
vip_address => '192.168.0.102',
source_address => '192.168.0.2',
master_hostname => 'host002',
}
}
Or add the following hiera configuration to your host group
ucarp::bind_interface: "ens160"
ucarp::password: ProtectedPassword
ucarp::hosts:
'001':
vip_address: 192.168.0.101
master_hostname: host001
'002':
vip_address: 192.168.0.102
master_hostname: host002
'003':
vip_address: 192.168.0.103
master_hostname: host003
'004':
vip_address: 192.168.0.104
master_hostname: host004
