The invention discloses a method for realizing multi-line access of an external network based on OpenStack. The method comprises the following steps: acquiring an IP address of an operator; summarizing the obtained IP addresses and mapping the IP addresses to an intranet address with a preset bit number; setting a virtual router to an external gateway connected to a first preset IP in a gateway setting mode, forming a first interface in the virtual router, and adopting a second preset IP of the first interface for being connected with an external network; creating a plurality of virtual routing table files in the virtual router so as to correspond to an operator through each virtual routing table file; creating a policy route in the virtual router so as to associate different addresses with the virtual routing table; connecting a tenant network to the virtual router, generating a second interface in the router, and adopting the IP of the second interface as the internal gateway address of the tenant network so as to be used for connecting the internal network; configuring the floating IP on an external interface of the virtual router through a neutron component, and setting a processing rule of the floating IP in the virtual routing table file.
Description
technical field [0001] The invention relates to the technical field of OpenStack external network multi-line access, in particular to a method for realizing external network multi-line access based on OpenStack. Background technique [0002] OpenStack is an open source cloud operating system that can control large computing, storage, network and other resource pools through the data center. All management can be done through the front-end interface administrator, and end users can also deploy resources through the web interface. [0003] OpenStack supports almost all types of cloud environments and has become the mainstream IaaS (Infrastructure as a Service) standard. It provides Infrastructure as a Service (IaaS) solutions through various services, and each service provides APIs for integration. Currently, there are multiple network server providers in China, and the network resources provided by different network providers have different addresses and gateways, etc., so t...
