All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to facilitate understanding of the present embodiment, the following describes embodiments of the present application in detail.
Embodiment one:
fig. 1 is a flowchart of a method for dynamically loading configuration files according to an embodiment of the present application.
Referring to fig. 1, applied to a CDN (Content Delivery Network ) device, the nginx may be considered as a CDN device, and in this embodiment, the configuration functions (conf files) of the nginx that are native are configured into different functional configurations according to the lua script, that is, the configuration functions of the nginx are lua-typed. 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 combining a plurality of functions according to the requirement, but is not limited thereto. . In addition, the configuration information may be configuration information obtained by lua of conf configuration information, for example, the conf configuration information of the nginx includes location, the conf file is divided into http, server and location, 3 layers are total, http is a first layer, server is a second layer, location is a third layer, each layer is a relationship contained, the server layer is the configuration for the whole domain name, and the location layer is the configuration for some paths of books under the domain name; the lua configuration corresponding to the location is uri (regular expression); where location is the meaning of a path.
Configuration information of nginx supports snoop ports (listen 80), corresponding lua configuration is port:80. where port is a function name, 80 is a port number, and listen 80 means listening to 80 ports. The original configuration of the nginx cannot support dynamic loading, and after the lua configuration, the configuration of the same function supporting dynamic loading is realized.
In this embodiment, when the client sends the request information to the CDN device, the CDN device searches 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 equipment each time, the corresponding configuration information is acquired from the shared memory, so that reloading operation is avoided, and the performance of the CDN equipment is stable.
Further, the shared memory stores a first designated file, wherein the first designated 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 format table file, which is a lua-formatted file; the first specified file may be a json-format table file, but is not limited thereto.
Further, the method comprises the following steps:
step S201, monitoring whether a second designated file under a designated directory of the CDN device is updated; wherein the second designated file stores a corresponding relation;
step S202, under the condition that the second designated file is updated, the difference file received from the configuration file issuing system is synchronized into the first designated file in the shared memory.
It should be noted that, the above configuration file issuing system issues the differential file to the specified directory of the CDN device, and in case that it is monitored that the second specified file is updated, the CDN device may directly synchronize the differential file in the specified directory to the shared memory of the CDN device, without synchronizing the entire second specified file to the shared memory, thereby further saving the update time. Further, step S102 includes at least one of:
under the condition that the first specified file is not 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 first specified file which is not updated in the shared memory according to the domain name information;
and 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 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.
Specifically, 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 under the condition that the first specified file in the shared memory is not updated, the configuration information corresponding to the domain name information is obtained from the first specified file which is not updated according to the domain name information.
And under the condition that the updating of the first specified file in the shared memory is completed, if the client side 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, acquiring the configuration information corresponding to the domain name information from the updated first specified file according to the domain name information.
In an embodiment of the present application, the configuration file delivery system may deliver the difference file to the specified directory of the CDN device and also deliver the latest complete configuration file (for example, the latest second specified file) in the specified directory, where the latest complete configuration file is received by the CDN device and directly covers the second specified file stored in the specified directory before the latest complete configuration file is stored, and at this time, the time attribute of the updated second specified file may be changed. Thus, the CDN device checks the second designated file in each cycle to determine a latest modification time of the second designated file, and if the latest modification time is unchanged, it indicates that the second designated file is not updated; if the latest modification time is changed, the second designated file is indicated to be updated.
Thus, the step S201 may include:
monitoring whether the time attribute of the second designated file is changed; and determining that the second designated file is updated when the time attribute is not changed.
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 is subordinate to the second domain name information, referring to fig. 2, step S102 further includes the steps of:
step S301, searching configuration information corresponding to the first domain name information from a shared memory according to the first domain name information;
in step S302, if no configuration file is found, the configuration information corresponding to the second domain name information is obtained from the shared memory according to the second domain name information.
Here, the first domain name information may be precise domain name information, and the second domain name information may be general 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 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 is more diversified, and the searching efficiency is improved.
