Detailed Description
The Nginx (engine x) is a high-performance HTTP and reverse proxy web server, and can be used as an HTTP server to perform website publishing processing, and can be used as a reverse proxy to perform load balancing. In the embodiment of the present application, mainly, the negative proxy server is Nginx. Regarding the way of dealing with reverse proxy, taking a certain X website as an example, the number of visitors who are connected to the website at the same time every day is already exploded, and a single server is far from meeting the increasing purchasing desire of people, and at this time, a well-understood term appears: distributed deployment; namely, the problem of limitation of the number of visitors is solved by deploying a plurality of servers.
Most functions in an X website are also implemented by directly using a reverse proxy by using a Nginx, and a specific deployment manner may be as shown in fig. 1. As can be seen from fig. 1, the reverse proxy process performed by Nginx is as follows: after receiving the request sent by the plurality of clients to the Nginx server, the Nginx server distributes the request to the service processing server at the back end according to a certain rule for processing. At this time, the source of the request, that is, the user terminal, is clear, but it is not clear which server the request is specifically processed by, the role played by nginn is a reverse proxy role, the client is unaware of the existence of the proxy, the reverse proxy is transparent to the outside, and the visitor does not know that the visitor accesses the proxy. As the user terminal does not need any configuration to be accessible. Wherein, the reverse proxy has the following functions: the safety of the intranet is guaranteed, the reverse proxy is generally used as a public network access address, and the Web server is the intranet. And load balancing, namely optimizing the load of the website through a reverse proxy server.
Taking Nginx as a reverse proxy server, please refer to fig. 2, an embodiment of the present application provides a service deployment system, which includes amanagement server 20, aclient 21 corresponding to the management server, areverse proxy server 22, at least oneservice server 23, and at least oneuser terminal 24. Eachservice server 23 may deploy one or more services, themanagement server 20 is configured to manage service configuration data representing access weights of the service servers, and send the service configuration data to thereverse proxy server 22, and thereverse proxy server 22 is configured to control forwarding amounts for forwarding access requests from theuser terminal 24 to the service servers based on the service configuration data. The management server, the service server and the reverse proxy server may be independent physical servers, or may be a server cluster or a distributed system formed by a plurality of physical servers.
The services referred to in the embodiments of the present application may refer to, for example, login services, payment services, and the like provided for a user, and each service may correspond to a plurality of business servers. Taking the login service as an example, the service server 1 corresponding to the service may be used to provide a username-password login service, and the service server 2 corresponding to the service may be used to provide a code scanning login service.
The service deployment system further includes a reverse proxy server, at least one service server deployed with a service, and a client corresponding to the management server, where the management server is configured to manage service configuration data representing access weights of the service servers, and issue the service configuration data to the reverse proxy server, and the reverse proxy server is configured to control forwarding amounts for forwarding access requests to the service servers based on the service configuration data. Referring to fig. 3, the method of the embodiment of the present application includes the following steps.
S301: and receiving a service deployment updating request from the client, wherein the service deployment updating request carries the identification information of the service server. The identification information of the service server may refer to a number for uniquely identifying the service server, and the like.
In a specific implementation, when a user wants to update a service deployed by a target service server, the target service server may be selected from a service server list displayed by a client, and a service deployment update operation may be input for the target service server (for example, after the target service server is selected, a service update button of a currently displayed page is clicked and pressed). After detecting the operation of the service deployment update, the client can acquire the identification information of the target service server and send a service deployment update request carrying the identification information of the target service server to the management server.
S302: and determining a target service server matched with the identification information from the started service servers.
In a specific implementation, the management server may detect an operation state of each service server in the service deployment system, and determine a started service server based on the operation state. Further, the target service server corresponding to the identification information can be queried from the started service server through the identification information.
S303: and acquiring a pre-configured access weight of the target service server, and adjusting the pre-configured access weight to zero to obtain a new access weight corresponding to the target service server.
In an embodiment, a service configuration page may be displayed through a client in advance, a user may configure an access weight (that is, a preconfigured access weight) of each service server in the service configuration page, after the configuration is completed, service configuration data for each service server may be generated and uploaded to a management server, the management server may store the service configuration data and issue the service configuration data to a reverse proxy server, and the reverse proxy server may control a forwarding amount of forwarding an access request to each service server based on the access weight of each service server indicated by the service configuration data.
Specifically, the size of the access weight corresponding to each service server is in a direct proportion to the forwarding amount of the reverse proxy server forwarding the access request to each service server. It can be understood that, the higher the access weight of any service server is, the greater the number of access requests that characterize the reverse proxy server to forward to the any service server is, that is, the greater the corresponding forwarding amount is, and conversely, the smaller the forwarding amount is. If the access weight of any service server is 0, the number of the access requests forwarded to any service server by the reverse proxy server is represented to be 0, that is, the corresponding forwarding amount is 0.
S304: and determining other service servers which have the same service as the target service server and are deployed in the started service servers, and adjusting the pre-configured access weights of the other servers according to a preset adjustment rule to obtain new access weights corresponding to the other service servers.
The services may refer to, for example, a login service, a payment service, and the like provided for a user, and each service may correspond to a plurality of service servers. Exemplarily, it is assumed that the service deployment system includes a service server 1, a service server 2, a service server 3, a service server 4, and a service server 5, where the service server 1 and the service server 2 are both configured to provide a login service, and the service server 3, the service server 4, and the service server 5 are all configured to provide a payment service. Then, when the target service server is the service server 3, the service server 4 and the service server 5 may be determined as other service servers having the same service as that deployed by the service server 3.
The preset adjustment rule is that, for example, the service provided by the target service server is a login service, the provided login service further includes a service server 1 and a service server 2, and the preconfigured access weights of the target service server, the service server 1 and the service server 3 are 0.4, 0.2 and 0.4, respectively, so that the preset adjustment rule may be that the preconfigured access weights of the target service server are averagely allocated to other servers providing the same service. In this case, after the access weight corresponding to the target service server is modified to 0, the access weight of the service server 1 may be updated to 0.4, and the access weight of the service server 2 may be updated to 0.6.
S305: and generating new service configuration data based on the new access weights corresponding to the target service server and other servers respectively.
In an embodiment, service configuration data before updating of the access weight corresponding to the current target service server and the other servers may be obtained (for example, the service configuration data obtained by configuring the access weight of each service server through the service configuration page). Further, the access weight parts corresponding to the target service server and other servers in the service configuration data can be updated through the new access weights corresponding to the target service server and other servers, so that new service configuration data can be obtained.
S306: and sending the new service configuration data to the reverse proxy server, and returning the update confirmation indication information aiming at the target service server to the client.
The new service configuration data is used for indicating the reverse proxy server to control the forwarding amount of the access request to the target service server and other servers based on the new access weight corresponding to the target service server and other servers respectively. And if the new access weight corresponding to the target service server is zero, the forwarding amount corresponding to the target service server is zero.
And the update confirmation indication information is used for prompting the client to update the service deployed by the target service server corresponding to the user. That is, when the user corresponding to the client checks the update confirmation indication information through the client, it can be known that the preparation work for updating the service deployed by the target service server is completed ((that is, the access weight is updated)), and the user can perform the subsequent operation of service update on the target service server. By adopting the mode, in the subsequent process of updating the corresponding service of the target service server, the reverse proxy server can be ensured not to issue the access request to the target service server, but to deliver the access request to other servers providing the same service for processing based on the corresponding access weight. Compared with the traditional service deployment, the method has the advantages that part or all of the servers do not need to be stopped, and then the services are updated.
In the embodiment of the application, the access weights of the target service server and other service servers providing the same service as the target service server can be updated by adjusting the access weights, and subsequently, in the service updating process of the target service server, the reverse proxy server can not issue the access request to the target service server, but can deliver the access request to other service servers providing the same service to process the access request based on the corresponding access weights, so that the normal response to the access request in the service updating process is ensured. Compared with the traditional service deployment, the method has the advantages that part or all of the servers do not need to be stopped, and then the services are updated.
Referring to fig. 4, the present application provides another service updating method, which may be executed by a management server in a service deployment system, where the service deployment system further includes a reverse proxy server, at least one service server deployed with a service, and a client corresponding to the management server, where the management server is configured to manage service configuration data representing access weights of the service servers, and send the service configuration data to the reverse proxy server, and the reverse proxy server is configured to control forwarding amounts of forwarding access requests to the service servers based on the service configuration data. Referring to fig. 4, the method of the embodiment of the present application includes the following steps.
S401: acquiring service information of each service server, wherein the service information comprises any one or more of the following: internet protocol, port information, location information, identification information, and service description information of the corresponding service provided. The service description information characterizes what service the corresponding service server is used for providing, such as user password login service, code scanning login service, and the like.
As a feasible implementation manner, the SDK of the monitoring program may be integrated into each service server in advance, and the SDK may collect service information of each service server after each service server is started, and report the collected service information to the management server.
S402: and determining a pre-configured access weight corresponding to each business server, and generating and storing service configuration data aiming at each business server based on the service information and the pre-configured access weight of each business server. Wherein the service configuration data comprises preconfigured access weights and service information of the respective service servers.
In one embodiment, the service information includes location information, and after the management server performs step S402, the management server may further perform statistics on access requests received by the reverse proxy server, determine an access request amount of each region within a preset time period according to a statistical result, extract location information of each service server from the service configuration data, and determine a region where each service server is located based on the location information. Further, the preconfigured access weights of the service servers in different regions in the service configuration data can be adjusted according to the access request amount of each region in a preset time period.
In the above process of adjusting the preconfigured access weights of the service servers in different regions in the service configuration data according to the access request amount of each region in the preset time period, the adjustment may be performed based on a principle that the larger the access request amount is, the larger the corresponding access weight is. Exemplarily, assuming that the access request volume in the beijing area is relatively high within a preset time period, the access weight of the service server deployed in beijing may be correspondingly adjusted, the resources may be dynamically adjusted, and the response speed to the access request may be improved.
In an embodiment, after the service configuration data for each service server is generated and stored, the operation condition of each service server may also be detected, and if an operation failure of a first service server in each service server is detected, the preconfigured access weight of the first service server is adjusted to zero, so as to obtain a new access weight corresponding to the first service server, where the first service server is any one or more service servers in each service server. Further, a second service server with the same service as the first service server deployed may be determined from the started service servers, the preconfigured access weight of the second service server is adjusted according to a preset adjustment rule, a new access weight corresponding to the second service server is obtained, the service configuration data is updated based on the new access weights corresponding to the first service server and the second service server, and the updated service configuration data is sent to the reverse proxy server. So that the reverse proxy server can forward the access request based on the updated service configuration data.
S403: and receiving a service deployment updating request from the client, wherein the service deployment updating request carries the identification information of the service server.
S404: and determining a target service server matched with the identification information from the started service servers.
S405: and acquiring a pre-configured access weight of the target service server, and adjusting the pre-configured access weight to zero to obtain a new access weight corresponding to the target service server.
S406: and determining other service servers which have the same service as the target service server and are deployed in the started service servers, and adjusting the pre-configured access weights of the other servers according to a preset adjustment rule to obtain new access weights corresponding to the other service servers.
S407: and generating new service configuration data based on the new access weights corresponding to the target service server and other servers respectively.
S408: and sending the new service configuration data to the reverse proxy server, and returning the update confirmation indication information aiming at the target service server to the client. For specific implementation of steps S403 to S408, refer to the description related to steps S301 to S306 in the foregoing embodiment, and details are not repeated here.
In an embodiment, after the update confirmation indication information for the target service server is returned to the client, if it is detected that the service deployed for the target service server is updated, the access weights corresponding to the target service server and the other servers are restored based on the pre-recorded access weight before the target service server is updated and the pre-updated access weight of the other servers. Further, the new service configuration data may be updated based on the respective access weights corresponding to the restored target service server and other servers, and the updated service configuration data may be sent to the reverse proxy server.
Or, updating the service configuration data based on the restored access weight also requires occupying a certain resource. In order to improve the speed of restoration, the service configuration data before updating can be recorded directly before updating the access weights of the target service server and the other servers, if the completion of service updating deployed for the target service server is detected, the service configuration data before updating of the access weights corresponding to the target service server and the other servers which are recorded in advance are obtained, and the service configuration data before updating is issued to the reverse proxy server, so that the reverse proxy server controls the forwarding amount of forwarding the access request to each service server based on the service configuration data before updating.
In the embodiment of the application, the access weights of the target service server and other service servers providing the same service as the target service server can be updated by adjusting the access weights, and subsequently, in the service updating process of the target service server, the reverse proxy server can not issue the access request to the target service server, but can deliver the access request to other service servers providing the same service to process the access request based on the corresponding access weights, so that the normal response to the access request in the service updating process is ensured. Compared with the traditional service deployment, the method has the advantages that part or all of the servers do not need to be stopped, and then the services are updated.
