All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any creative effort, shall fall within the protection scope of the present invention.
For the understanding of the present embodiment, the following detailed description will be given of the embodiment of the present invention.
The first embodiment is as follows:
fig. 1 is a flowchart of a method for dynamically loading a configuration file according to an embodiment of the present invention.
Referring to fig. 1, the present invention is applied to a CDN (Content Delivery Network) device, where nginx may be considered as a CDN device, and in this embodiment, a native nginx configuration function (conf file) is configured to correspond to a different function configuration according to a lua script, that is, the nginx configuration function is lua-converted. The method comprises the following steps:
step S101, receiving request information sent by a client, wherein the request information comprises domain name information corresponding to the client;
step S102, obtaining configuration information corresponding to the domain name information from a shared memory of the CDN device according to the domain name information.
It should be noted that the configuration information may include a plurality of functions, that is, may be formed by combining a plurality of functions, and one configuration information may correspond to one domain name, that is, the complete configuration information corresponding to one domain name may be formed by configuring and combining a plurality of functions as required, but is not limited thereto. . In addition, the configuration information may be configuration information obtained by lua transformation of conf configuration information, for example, there are location in conf configuration information of nginx, the conf file is divided into http, server and location, which total 3 layers, http is the first layer, server is the second layer, location is the third layer, each layer is an included relationship, the configuration of the server layer is for the whole domain name, and the location layer is for the configuration of some paths of the book under the domain name; wherein, the lua configuration corresponding to the location is uri (regular expression); here, location means a path.
The configuration information of nginx supports a listening port (listen 80), and the corresponding lua configuration is port: 80. Wherein, port is function name, 80 is port number, and listen 80 means listening to 80 ports. The original configuration of nginx cannot support dynamic loading, and the configuration of the same function of supporting dynamic loading is realized after the lua configuration.
In this embodiment, when the client sends the request information to the CDN device, the CDN device searches for the domain name information from the shared memory according to the domain name information in the request information, and obtains configuration information corresponding to the domain name information. And when the client sends the request information to the CDN device, the corresponding configuration information is obtained from the shared memory, so that the reloading operation is avoided, and the performance of the CDN device is stable.
Further, the shared memory stores a first specific file, wherein the first specific file stores a corresponding relationship between the domain name and the configuration information.
Here, the first specified file is obtained by reading the second specified file from the directory, or is obtained from the second specified file and the difference file. The second specified file may be a json-formatted table file, which is a lua-formatted file; the first specific file may be a json table file, but is not limited thereto.
Further, the method comprises the following steps:
step S201, monitoring whether a second specified file under a specified directory of CDN equipment is updated; wherein, the second specified file stores the corresponding relation;
step S202, synchronizing the difference file received from the configuration file issuing system to the first specified file in the shared memory when it is monitored that the second specified file is updated.
It should be noted that, the configuration file issuing system issues the difference file to the specified directory of the CDN device, and when it is monitored that the second specified file is updated, the CDN device may directly synchronize the difference file in the specified directory into the shared memory of the CDN device, without synchronizing the entire second specified file into the shared memory, so that the update time is further saved. Further, step S102 includes at least one of:
under the condition that the first designated file is not updated completely and the configuration information corresponding to the request information comprises part or all of the content of the difference file, acquiring the configuration information corresponding to the domain name information from the first designated file which is not updated in the shared memory according to the domain name information;
and under the condition that the first specified file is updated and the configuration information corresponding to the request information comprises part or all of the content of the difference file, acquiring the configuration information corresponding to the domain name information from the updated first specified file in the shared memory according to the domain name information.
Specifically, under the condition that the first specific file in the shared memory is not updated, if the client sends the request information and the configuration information corresponding to the request information includes part or all of the content of the difference file, the configuration information corresponding to the domain name information is acquired from the first specific file which is not updated according to the domain name information.
Under the condition that the updating of the first specified file in the shared memory is completed, if the client sends the request information again and the configuration information corresponding to the request information comprises part or all of the content of the difference file, the configuration information corresponding to the domain name information is acquired from the updated first specified file according to the domain name information.
In an embodiment of the application, the configuration file issuing system issues the difference file to the specified directory of the CDN device and also issues a latest complete configuration file (for example, a latest second specified file), and when the CDN device receives the latest complete configuration file, the second specified file stored in the specified directory before the CDN device directly overwrites the latest complete configuration file, and at this time, a time attribute of the updated second specified file changes. Therefore, the CDN device checks the second specified file in each period to determine the latest modification time of the second specified file, and if the latest modification time is not changed, it indicates that the second specified file is not updated; if the latest modification time is changed, the second specified file is updated.
Thus, the step S201 may include:
monitoring whether the time attribute of the second specified file is changed; and when the monitored time attribute is not changed, determining that the second specified file is not updated.
It should be noted that the time attribute may be a modification date or a modification time, but is not limited thereto.
Further, the domain name information includes first domain name information and second domain name information, the first domain name information belongs to the second domain name information, referring to fig. 2, step S102 further includes the following steps:
step S301, searching configuration information corresponding to the first domain name information from a shared memory according to the first domain name information;
step S302, if the configuration file is not found, obtaining configuration information corresponding to the second domain name information from the shared memory according to the second domain name information.
Here, the first domain name information may also be precise domain name information, and the second domain name information may be pan domain name information, but is not limited thereto.
Specifically, when the memory is updated, the corresponding configuration information can be searched through the first domain name information and the second domain name information, the first domain name information is firstly used for searching, and if the corresponding configuration information is not searched through the first domain name information, the second domain name information is used for searching, so that the searching of the configuration information can be more diversified, and the searching efficiency is improved.
