One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t

In this example, I will configure a cloud service Travelweb, which has two VMs, which together provide HTTP services1. Create the first VM TRAVELWEB01, specify the cloud service name as Travelweb when you create it, add an HTTP endpoint2. Create a second VM TRAVELWEB02, using the existing cloud service TravelwebAt this point, both VMs are under the same
