Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
An embodiment of the present application provides a communication transmission method, which is executed by a public cloud server, and as shown in fig. 1, provides a flowchart of the communication transmission method in the embodiment of the present application, where the method at least includes the following steps S110 to S130:
step S110, deploying a Nginx server in a public cloud, wherein the Nginx server is configured with a multi-computer-room access strategy in a private cloud.
The public cloud is a cloud which can be used and is provided by a third-party provider for a user, can be generally used through the Internet, has a core attribute of shared resource service, has a plurality of instances, and can provide service in the whole open public network. In the embodiment of the application, the arriyun cloud is mainly used as an internet outlet for communication transmission, and certainly, a person skilled in the art can also flexibly select other types of public clouds, such as Tencent cloud, according to actual needs, which is not specifically limited herein.
The communication transmission method of the embodiment of the application can be executed by a public cloud server, and when communication transmission is performed, a Nginx server can be deployed in the public cloud, wherein the Nginx server is a high-performance Http and reverse proxy server, can be used as an Http server to perform release processing of a website, and can also be used as a reverse proxy to perform load balancing.
Based on configurability of the Nginx server, the multi-machine-room access strategy in the private cloud is configured in the Nginx server of the public cloud in the embodiment of the application, and the multi-machine-room access strategy in the private cloud can be understood as an access strategy of the Nginx server in the public cloud to a plurality of machine rooms in the private cloud in a distributed multi-machine-room service scene of the private cloud.
Step S120, receiving an Http request through an Nginx server in the public cloud, wherein the Http request refers to a request for accessing multiple computer rooms in the private cloud.
After the Nginx server is deployed in the public cloud, the Http request initiated by the user side can be received through the Nginx server in the public cloud, where the Http request may be various types of requests initiated by the user side to access multiple computer rooms in the private cloud in an actual service scene, such as a transaction request, a clearing request, and the like, which is not specifically limited herein.
Step S130, according to a multi-machine-room access strategy in a private cloud configured in the Nginx server, sending the Http request to a Nginx server of a target machine room in the private cloud so as to provide Http service through the Nginx server of the target machine room in the private cloud, wherein the target machine room is a machine room determined according to the multi-machine-room access strategy.
Since the private cloud adopts a multi-machine-room architecture, after the Nginx server in the public cloud receives the Http request, the ngnx server in the private cloud needs to determine to which Nginx server the Http request is sent according to a multi-machine-room access policy in the private cloud configured in the Nginx server, that is, a target machine room is determined, and the Nginx server in the target machine room can provide corresponding Http service.
In the existing communication transmission method between the public cloud and the private cloud, only the Nginx server is deployed on the layer of the private cloud, and the layer of the public cloud can only depend on the load balancing service provided in the public cloud to realize random routing of multiple machine rooms in the lower-layer private cloud, so that the actual service requirement under the distributed multi-machine room service scene cannot be met.
The communication transmission method provided by the embodiment of the application is characterized in that a Nginx server which is in communication transmission with a private cloud side is further arranged on the basis of the existing public cloud side, and a multi-computer-room access strategy of the private cloud is configured in the Nginx server of the public cloud based on the configurability of the Nginx server, so that the public cloud can access according to the multi-computer-room access strategy of the private cloud configured inside when in communication transmission with the private cloud based on the framework of the double-layer Nginx server, and the non-random routing ensures the high availability and the service continuity of the system and meets the actual requirements under the service scene of the distributed multi-computer-room.
In one embodiment of the present application, the public cloud including a plurality of available zones therein, the deploying an Nginx server in the public cloud comprising: and respectively deploying a plurality of Nginx servers in each available area, and configuring the plurality of Nginx servers deployed in each available area into a multi-active mode.
An available Zone (AZ for short) refers to a physical area where power and a network are independent from each other in the same geographical area. Network delay between the instances in the same available area is smaller, intranet intercommunication between the available areas in the same region can be realized, and fault isolation can be realized between the available areas. Taking the ali cloud as an example, in order to provide more stable and reliable load balancing service for users, the ali cloud load balancing has deployed a plurality of available areas in each Region (Region) to realize cross-machine room disaster recovery in the same Region. When the machine room of the main available area fails or is unavailable, the load balancing still has the capability of switching to another machine room of the standby available area and recovering service in a very short time (about 30 seconds); when the main usable area recovers, the load balancing is automatically switched to the machine room of the main usable area to provide service.
In the embodiment of the application, a plurality of available areas are also deployed in the public cloud, and when the Nginx servers are specifically deployed in the public cloud, a plurality of Nginx servers, such as two or more Nginx servers, can be respectively deployed in each available area, so as to ensure high availability and service continuity of the system. Of course, one skilled in the art may also deploy only one nginnx server in each available area according to actual needs, and the number of specific configurations is not specifically limited herein.
In order to improve the disaster tolerance capability of the system, in the embodiment of the present application, multiple Nginx servers deployed in each available area may be configured in a multi-active mode. The multi-active mode of the Nginx server is understood to mean that two or more Nginx servers are in operation, run the same application, have the same data, and can achieve continuous application availability and disaster backup capability.
In an embodiment of the present application, load balancing servers are also respectively deployed in each available area of the public cloud, and the receiving, by an Nginx server in the public cloud, an Http request includes: receiving, by a load balancing server in the available region, the Http request; and sending the Http request to a target Nginx server deployed in the available area according to a load balancing strategy configured in the load balancing server, wherein the target Nginx server is any one of a plurality of Nginx servers deployed in the available area.
Taking the ali cloud as an example, a load balancing Server (SLB) is deployed in the ali cloud, and is designed mainly for the ali cloud elastic computing platform, and the use characteristics and specific service scenarios of the elastic computing server are fully considered in the aspects of system architecture, system safety and performance, and compatibility design.
In an actual service scenario, an Http request initiated by a user side is first sent to an SLB in an available area of an arii cloud, and then the SLB sends the Http request to a target Nginx server deployed in the available area according to a load balancing policy configured in advance, so that the target Nginx server forwards subsequent requests.
The load balancing policy mainly includes a polling policy, a weighted minimum connection number policy, and the like, and these load balancing policies are usually set in advance in the SLB of the airy cloud, so that it is not necessary to pay attention to which load balancing policy is specifically adopted in the SLB in the embodiment of the present application.
In an embodiment of the present application, the private cloud is deployed with a plurality of machine rooms, the multi-machine-room access policy in the private cloud is a machine-room multi-active policy, and the sending the Http request to the nginnx server of the target machine room in the private cloud according to the multi-machine-room access policy in the private cloud configured in the nginnx server includes: and distributing the Http request to an Nginx server of a target machine room according to the machine room multi-activity strategy according to a preset distribution principle, wherein the target machine room is a machine room which is deployed in the private cloud and is in a survival state.
The private cloud is provided with a plurality of machine rooms, the access policies adopted by the machine rooms can be machine room multi-activity policies, and the machine room multi-activity policies can be understood as that two or more machine rooms in the private cloud are in operation, namely in an alive state, so that cross-machine room service load balancing operation capacity can be provided, and continuous application availability and disaster backup capacity are realized.
Under the condition that the private cloud adopts a machine room multi-activity strategy, a plurality of machine rooms in the private cloud are all in an active state and can receive and forward requests, so that when the Http request is distributed by the Nginx server in the public cloud, the Http request can be determined to be distributed to which machine room in the private cloud according to a certain distribution principle. The distribution principle adopted here may be a polling policy adopted in the SLB, for example, the requests are distributed one by one in sequence, and certainly, a random distribution policy may also be adopted, or a preset proportion mode may also be adopted for distribution, for example, 50% of the requests are distributed to the machine room a,30% of the requests are distributed to the machine room B,20% of the requests are distributed to the machine room C, and the like. Specifically, which distribution principle is adopted, those skilled in the art can flexibly set the distribution principle according to actual service requirements, and the distribution principle is not specifically limited herein.
In an embodiment of the application, the sending the Http request to the Nginx server of the target machine room in the private cloud according to the multi-machine-room access policy in the private cloud configured in the Nginx server includes: determining a main machine room in the private cloud as the target machine room according to the main machine room and standby machine room strategy; and sending the Http request to an Nginx server of the main computer room.
The multi-computer-room access strategy in the embodiment of the application can also be a computer-room main-standby strategy, that is, a main computer room and at least one standby computer room are deployed in a private cloud, in an actual service scene, only the main computer room provides service to the outside, and in the case of a failure of the main computer room, the standby computer room can take over the work of the main computer room, so as to ensure the high availability and the service continuity of the system.
If the access policy configured in the private cloud is a machine room master-standby policy, when the Http request is distributed by the Nginx server in the public cloud, the IP address of the current host room may be determined, and then the Http request is sent to the host room, so that the host room performs subsequent processing on the Http request.
The embodiment provides two access strategies, namely a machine room multi-active strategy and a machine room main-standby strategy, realizes the independent control of the access priority of the multiple machine rooms in the private cloud in the distributed multi-machine-room service scene, and meets the actual requirements in the distributed multi-machine-room service scene.
In an embodiment of the application, the sending the Http request to an Nginx server of a target computer room in a private cloud includes: and sending the Http request to an Nginx server of a target machine room in the private cloud through the private line connection between the public cloud and the private cloud.
The public cloud and the private cloud in the embodiment of the application can be connected by a private line, and the range of the accessible port is limited through NAT Address Translation (Network Address Translation). According to the embodiment of the application, the Http request is transmitted through the private line connection, so that the safety of a communication transmission process can be improved, the transmission speed can be increased, and the delay can be reduced.
Taking the airy cloud as an example, the access modes of the private line connection provided by the airy cloud include the following two modes, one mode is that the private line is independently applied for exclusive access, the private line is automatically pulled through a local machine room in the private cloud to an airy cloud access point, the mode monopolizes a physical port, and the high-speed channel console can be used for independently applying for the exclusive connection of the physical private line. The other is sharing access of a cooperative partner, the access point of the cooperative partner is already in butt joint with the access point of the Ali cloud, and the private line deployment from a local machine room in the private cloud to the access point of the cooperative partner is completed only through the cooperative partner.
Of course, how to establish a dedicated line connection with a public cloud is specifically, and those skilled in the art can flexibly set the dedicated line connection according to actual needs, and no specific limitation is made.
In an embodiment of the application, each machine room in the private cloud is respectively deployed with a main Nginx server and a standby Nginx server, and the sending the Http request to the Nginx server of the target machine room in the private cloud includes: determining a main computer room in the private cloud and a main Nginx server in the main computer room; and sending the Http request to a main Nginx server in the main computer room.
In an actual service scenario, a plurality of Nginx servers are also deployed in each machine room of the private cloud, and the Nginx servers usually adopt an active-standby mode, that is, one machine room includes one main Nginx server and at least one standby Nginx server. Under normal conditions, only the main Nginx server in the main room provides external services, and when the main Nginx server in the main room fails, the standby Nginx server in the main room takes over the work of the main Nginx server to ensure high availability and service continuity of the system.
Based on this, when the naginx server in the public cloud of the embodiment of the present application forwards the request, the current host room and the IP address of the main naginx server in the host room may be determined, and then the Http request is sent to the main naginx server in the host room, so that the main naginx server performs subsequent processing on the Http request.
In an embodiment of the present application, a plurality of Nginx servers are respectively deployed in each machine room in the private cloud, each Nginx server in the private cloud is configured with an SSL security certificate, and the sending the Http request to the Nginx server of the target machine room in the private cloud includes: acquiring an SSL security certificate configured by an Nginx server in the private cloud; encrypting the Http request by using the SSL security certificate to obtain the Http request; and sending the Http request to a Nginx server of a target machine room in a private cloud to provide Http service through the Nginx server of the target machine room in the private cloud.
Although the existing communication transmission between the public cloud and the private cloud also adopts a special line connection mode, the existing transmission mode is generally not TLS (Transport Layer Security, secure Transport Layer protocol) for opening a Transport Layer because the communication transmission is usually considered to be secure, and in this case, if an Http request is directly transmitted, security risks still face.
In consideration of the situation, in the embodiment of the application, an SSL (Secure socket Layer protocol) security certificate is configured in advance in each Nginx server of the private cloud, and when the Nginx server in the public cloud sends the Http request to the Nginx server in the private cloud, the SSL security certificate configured on the Nginx server in the private cloud may be obtained first, and then the Http request is encrypted by using the SSL security certificate to obtain the Http request, so that the Http request is sent to the Nginx server in the private cloud, and the security of the transmission process is further improved.

It can be understood that, the communication transmission apparatus can implement the steps of the communication transmission method executed by the public cloud server provided in the foregoing embodiment, and the relevant explanations about the communication transmission method are all applicable to the communication transmission apparatus, and are not described herein again.
The embodiment of the application further provides a communication transmission system which comprises a public cloud server and a private cloud server, wherein the public cloud server is used for any one of the methods.
As shown in fig. 3, a schematic structural diagram of a communication transmission system in the embodiment of the present application is provided. The method comprises the steps that a plurality of available areas are deployed on a public cloud side, an SLB and a plurality of Nginx servers are deployed in each available area, a plurality of machine rooms are deployed on a private cloud side, and a plurality of Nginx servers are deployed in each machine room.
When communication transmission is carried out, an SLB in a public cloud server receives an http request triggered by a user on an APP, and then the http request is sent to a corresponding Nginx server in the public cloud according to a load balancing strategy. And then the Nginx server in the public cloud sends the http request to a target Nginx server in the target machine room according to a pre-configured multi-machine-room access strategy in the private cloud, and finally the target Nginx server provides http service and returns the result to the user layer by layer.
It should be noted that, in the embodiment of the present application, the multiple active mode is uniformly adopted when the Nginx server proxies the APP.
In an embodiment of the present application, the multi-machine-room access policy in the private cloud includes a machine-room master-slave policy, and the private cloud server is configured to execute: determining a current state of a main room in the private cloud; and if the current state of the host computer room of the private cloud is a fault state, switching the host computer room, and receiving an Http request sent by an Nginx server in the public cloud through the switched host computer room.
The multi-computer-room access strategy in the private cloud can adopt a computer-room main-standby strategy, under the strategy, the current state of the main computer room in the private cloud can be detected according to a certain frequency, if abnormal conditions such as failure and the like of the main computer room in the private cloud are detected, the failed main computer room can be switched, and the standby computer room takes over the work of the failed main computer room, so that the high availability and the service continuity of the whole system are ensured.
In an embodiment of the present application, each machine room in the private cloud is respectively bound with a corresponding virtual IP address, and the private cloud server is further configured to execute: and if the current state of the host computer room of the private cloud is a fault state, drifting the virtual IP address of the host computer room to a standby computer room by using keepalive high-availability software so as to switch the host computer room of the private cloud.
Keepallded high-availability software is deployed in Nginx servers of the private cloud, the Keepallded is used for detecting the state of each Nginx server in a machine room, if one Nginx server is down or works in a fault, the Keepallded detects the state and removes the faulty Nginx server, and meanwhile, other Nginx servers are used for replacing the work of the Nginx server, so that the high availability of the system is ensured. In a similar way, when one machine room breaks down, the whole machine room can be automatically isolated, and meanwhile, other machine rooms are used for replacing the machine room.
When implementing the high availability function of the system, keepalived may bind the corresponding virtual IP address (VIP for short) to each computer room in advance, where the VIP may be understood as an IP that is not allocated to a real host, that is, a virtual IP address is provided for a Nginx server that provides a service to the outside in addition to a real IP address, and any one of the two IP addresses may be used to connect to the Nginx server, and the virtual IP address is generally used in actual use. When the machine room fails and cannot provide service to the outside, keepalived can dynamically switch the virtual IP address of the machine room to a standby machine room, so that switching of the main machine room and the standby machine room is realized, and high availability of the system is ensured.
Because the existing communication transmission mode between the private cloud and the public cloud is mainly realized by the SLB deployed in the public cloud based on a load balancing strategy, namely, the request is forwarded by adopting a random routing mode, the mode ignores the states of all machine rooms in the private cloud and the actual requirements in a distributed multi-machine room service scene.
In the embodiment of the application, the multi-machine-room access strategy of the private cloud is configured in the public cloud, so that when the Nginx server in the public cloud carries out request forwarding, the access priorities of a plurality of machine rooms in the private cloud can be autonomously controlled according to the multi-machine-room access strategy, the high availability and the service continuity of the system are ensured, and the actual requirements under the distributed multi-machine-room service scene are met.
