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

1 overviewIn order to guarantee the stable operation of the bastion host-instruction channel, it is necessary to implement the load balance of instruction channel, and study to determine the use of LVS software.LVS is the abbreviation for Linux virtual server, that is, the Linux server, the official site is: www.linuxvirtualserver.org2 LVS ArchitectureLVS set up

. Instead of executing the LVS script we configured above, because Ldirectord will automatically call Ipvsadm to create the LVS routing table, we have described above using the IPVSADM command line to configure LVS in order to give readers a deeper understanding of IPVSADM implementation details and implementation mechanisms.If you are configuring LVS through the Piranha tool, you do not need to use the Ldirectord,piranha tool for the system process is pluse, this process will also automatically
