Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The internet IP is an IP address of a device in the internet, through which other devices connected to the internet can be accessed. Internet IP requires paid provisioning by an Internet Service Provider (ISP).
Vendors providing cloud platform services typically purchase a certain number of internet IPs, which are rented to users of the cloud platform services along with the cloud services.
In the design of the existing cloud platform, only an external network (public network) is created. In this way, when creating a virtual machine, in order to implement internet access, only one external network IP (also internet IP) address can be allocated to the cloud host as a fixed IP, so that other devices in the internet can access the cloud host by routing to the fixed IP. Other terminal equipment can directly access the cloud host by accessing the internet IP address.
In fact, although the manner of accessing the cloud host through the fixed IP directly solves the problem that the external user accesses the cloud host through the internet, the method may cause waste of IP resources for the cluster user. For example, for a certain integrator user who uses a plurality of cloud hosts as a cluster, there is only one cloud host in the cluster that provides an external access function. Then, the internet IP used as the fixed IP in the other cloud hosts is actually idle and does not perform the function of providing internet access. At this level, a lot of internet IP resources are wasted. Moreover, the user himself also incurs high costs.
The method aims to provide a scheme, so that the total number of internet IPs in the cluster is reduced as much as possible, and meanwhile, normal internet service is not influenced.
The floating IP is an IP address which does not target a specific cloud host, does not bind a certain cloud host, and corresponds to the cloud host one to one.
Computers in a network represent their identity by IP addresses, one IP address representing only a particular computer. A number of services, such as database services, FTP services, Web services, etc., may be provided simultaneously on a single computer. In the IP protocol, different services provided by a computer are generally distinguished by different logical ports. The ports of one IP address are numbered by 16 bits and there may be a maximum of 65536 ports. Ports are labeled by port number, which is only an integer, ranging from 0 to 65535.
But a large proportion of the 65536 ports are idle and fully functional. In fact, only one port of the internet IP is mapped to one cloud host, and when the terminal accesses the port, the terminal can access the cloud host.
Based on this, the application provides a network access method. In the construction phase of the cluster, a plurality of ports of one internet IP are mapped with a plurality of cloud hosts in the cluster by means of the floating IP. When the cloud host in the cluster is accessed, the corresponding cloud host can be accessed according to the port number of the Internet IP.
Fig. 1 is a schematic diagram of an application scenario provided in the present application. The scheme of the application can be used for an access process of the cloud host in the cluster. As shown in fig. 1, a cluster includes three cloud hosts 101, 102, and 103, where two of the cloud hosts 101 and 102 provide internet access. The two cloud hosts share the internet IP114.40.24.180, but correspond to different ports. 101 corresponds to a port 22880, and provides office management services (OA system); 102 correspond to port 23880 which provides financial management services (ERP system). The client terminal may initiate an access request to the OA system or the ERP system through the browser. After receiving the access request, the cloud platform management system of the cluster may associate to the corresponding cloud host according to the port of the specific IP address requested to be accessed. Specific access procedures may refer to the following embodiments.
Fig. 2 is a flowchart of a network access method according to an embodiment of the present application, and as shown in fig. 2, the method according to the embodiment may include:
s201, receiving a network access request, wherein the network access request comprises a port address of an Internet IP corresponding to a cloud host to be accessed.
A user with a network access requirement can initiate an access request to a target website through a browser of the terminal equipment. The user can input a port corresponding to the internet IP of the target website or input a domain name of the target website on an input interface of the terminal device.
Or the user may initiate a service request through a corresponding application in the terminal device.
The "network access request" referred to in the present application is not a request initiated by a user, but request information finally received by the cloud platform. According to the characteristics of network access, the request initiated by the terminal equipment can finally reach the network equipment pointed by the target address through a plurality of gateway equipment.
S202, according to the port address of the Internet IP and the preset mapping relation between the plurality of ports of the Internet IP and the plurality of floating IPs, the floating IP address corresponding to the cloud host to be accessed is determined.
The one-to-one mapping relation between a plurality of ports of the internet IP and a plurality of floating IPs is preset, and when an access request for the corresponding ports of the internet IP is received, the corresponding floating IPs can be determined.
S203, determining the cloud host to be accessed according to the floating IP address corresponding to the cloud host to be accessed and the incidence relation between the plurality of floating IPs and the plurality of fixed IP addresses.
The floating IP is used as an external network IP of the cloud host and has a corresponding incidence relation with the fixed IP of the cloud host. After the floating IP is determined, the fixed IP can be determined according to the association relation, and then the cloud host pointed by the fixed IP is accessed.
The fixed IP refers to an IP fixed by the device, and is equivalent to the identifier of the device.
The network access method provided by the embodiment comprises the following steps: receiving a network access request, wherein the network access request comprises a port address of an internet IP corresponding to a cloud host to be accessed; determining a floating IP address corresponding to a cloud host to be accessed according to the port address of the Internet IP and the preset mapping relation between a plurality of ports of the Internet IP and a plurality of floating IPs; and determining the cloud host to be accessed according to the floating IP address corresponding to the cloud host to be accessed, and the incidence relation between the plurality of floating IPs and the plurality of fixed IP addresses. By constructing the mapping relation between the plurality of ports of the internet IP and the plurality of floating IPs, the cloud host corresponding to different floating IPs can be reached when different ports of the internet IP are accessed. Therefore, the method can realize that one internet IP corresponds to a plurality of cloud hosts. Compared with the condition that one internet IP corresponds to one host in the prior art, a large amount of internet IP resources can be saved, and meanwhile, the cluster construction cost is also reduced.
In some embodiments, the fixed IP and the floating IP of each cloud host may be determined by establishing a local area network and allocating a VLAN.
Specifically, a virtual local area network VLAN may be constructed for a plurality of cloud hosts in a cluster; and acquiring a plurality of first intranet IPs and a plurality of second intranet IPs from the VLAN pool.
And the IP of the cloud host in the local area network is the intranet IP.
In the present application, the first intranet IP and the second intranet IP are both virtual IPs obtained from a VLAN pool, and the prefixes first and second are only used for distinguishing specific uses of the virtual IPs, and are used as fixed IPs or floating IPs.
Specifically, a first intranet IP may be allocated to each cloud host in the cluster as a fixed IP of the cloud host; and allocating a second intranet IP as a floating IP for each cloud host in the cluster which needs to provide services to the outside through the Internet.
Specifically, a first intranet IP may be allocated to each cloud host in the cluster; the first intranet IP is bound with the cloud host to serve as a fixed IP of the cloud host, and at the moment, the intranet IP becomes the attribute of the cloud host, is in a relatively stable relation, and is not unbound in general.
The fixed IP is the "ID" of the corresponding cloud host.
In addition, when a second intranet IP is allocated to each cloud host in the cluster, which needs to provide service to the outside through the internet, as a floating IP, a second intranet IP may be specifically allocated to each cloud host in the cluster, which needs to provide service to the outside through the internet; and then associating the second intranet IP with the fixed IP of the cloud host to serve as the floating IP of the cloud host.
After the floating IP is associated with the fixed IP, a one-to-one correspondence relationship is actually formed between the floating IP and the cloud hosts corresponding to the fixed IP.
The association relationship between the floating IP and the fixed IP may be stored in the cloud platform management system. And determining the target fixed IP by inquiring the association relation in the access process.
The process of allocating the fixed IP and the floating IP may be regarded as a configuration process of parameters of the cloud host.
The binding of the internet IP port and the floating IP specifically may include: acquiring an Internet Protocol (IP) of a cluster; and establishing a mapping relation between a plurality of floating IPs and a plurality of ports of the Internet IPs.
The cloud service provider may provide one or more internet IPs to the cloud service renter, which may be used for cluster construction. By adopting the scheme of the application, only one internet IP is needed in one cluster. A one-to-one mapping relation is established between a plurality of ports in one internet IP and a plurality of floating IPs, namely the ports can be mapped to the floating IPs in the access process of the internet IP ports, and then the ports are corresponding to the cloud host.
In some embodiments, the constructed mappings of the plurality of floating IPs to the plurality of ports of the internet IPs may be stored.
Specifically, the mapping relationship may be stored in a virtual address translation device in the cloud platform management system.
Because the floating IP is allocated, when the subsequent cloud host renting is finished, the cloud service provider can terminate the use of the Internet IP only by removing the association relation between the fixed IP and the floating IP.
In a specific embodiment, a large-scale cloud platform is built based on a processor of a LoongISA instruction set, and cloud service is provided. A user wants to apply for 4 cloud hosts to form a cluster. Wherein 4 cloud hosts all need to provide internet access service.
An internal network with address 10.80.230.0/24 is first created within the clustered lan environment. And dynamically allocating 4 intranet IPs to 4 cloud hosts as fixed IPs and 4 extranet IPs to 4 cloud hosts as floating IPs by using a software and hardware tool complying with a Dynamic Host Configuration Protocol (DHCP).
Second, a virtual router (virtual router) is created to connect the intranet IP with the floating IP route.
Then, 4 of the ports of the internet IP114.40.24.180 are mapped onto 4 floating IPs.
The correspondence between the final IP addresses is shown in fig. 3.
The client accesses https://114.40.24.180:22880, and the application software service provided on the 10.80.230.2 host is available. The Apache service on 10.80.230.5 host is available when the client accesses https://114.40.24.180: 25080.
The method and the device expand a large number of floating IPs by using a port mapping networking mode and are used for providing Internet external network access services. The external service is provided at the port layer of the application system, which just accords with the original service level of the system operation environment and can effectively solve the problem of the shortage of Internet IP resources.
