Embodiment Construction

[0027] Such as figure 1 , 2 As shown, configure the host network information: the host installs two network cards, eth0 and eth1 respectively, assuming that eth0 is connected to the external network, and eth1 is connected to the internal network; start the two network cards, and create the bridge br0 of the internal network card eth1 Make the following configuration:

[0028] The internal network eth1 configuration file / etc / sysconfig / network-script / ifcfg-eth0 is as follows:

[0029] DEVICE="eth1"

[0030] ONBOOT="yes"

[0031] BRIDGE=br0

[0032] The bridge br0 configuration file / etc / sysconfig / network-scripts / ifcfg-br0 is as follows:

[0033] DEVICE=br0

[0034] TYPE=Bridge

[0035] ONBOOT=yes

[0036] BOOTPROTO=static

[0037] IPADDR=192.168.6.22

[0038] NETMASK=255.255.255.0

[0039] GATEWAY=192.168.6.254

[0040] Create a virtual machine on the host and connect it to the host's internal network card in a bridge mode, that is, ensure that the network interface part of the virtual machine ...

Abstract

The invention relates to the field of cloud computing, in particular to a public network IP dynamic management method for a virtual machine. The public network IP dynamic management method for the virtual machine includes the steps of 1, installing at least two physical network interface controllers which are respectively used for being connected with an internal network and an external network on a host machine; 2, connecting a created virtual machine with the network interface controller of the internal network through bridging on the host machine; 3, installing and configuring the host machine with a DHCP (Dynamic Host Configuration Protocol) server of the internal network and allocating an internal network IP to the virtual machine; 4, starting an IP data packet forwarding function for the host machine; 5, configuring a sub-interface of the network interface controller of the external network of the host machine with a public network IP allocated to the virtual machine through the host machine; 6, finally achieving flexible binding of the virtual machine with the public network IP through NAT (Network Address Translation) on the host machine. The public network IP dynamic management method for the virtual machine solves the problems that the network configuration of the virtual machine is complex and confusing and the like and is applicable to IP management of the virtual machine.

Description

Technical field [0001] The invention relates to the field of cloud computing, in particular to a virtual machine-oriented dynamic management method of public network IP. Background technique [0002] In the era of cloud computing, virtual machines are provided to users in the form of services, and users on the public network need to access the virtual machines through the public IP. At the same time, because the virtual machines provided by cloud computing service providers need to be isolated by firewalls; therefore, in the traditional public network IP management method, the virtual machine’s actually configured IP is an internal network IP, and the public network IP and internal network IP are configured through the firewall. The mapping relationship of the network IP, when the public network user accesses the virtual machine through the public network IP, the firewall forwards the connection to the corresponding virtual machine. This management method has the following disad...
