Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
In the existing CDN function module operation method, as shown in fig. 2, after receiving a request packet for a certain domain name, an edge node needs to traverse all switch identifiers of function modules in a full configuration file, for example, switch identifiers of 12 function modules in fig. 2 need to be traversed, and for the domain name a, all the function modules 1, 3, 4, 6, 7, 8, 9, 11, and 12 are skipped when only detecting a switch identifier, and only the function modules 2, 5, and 10 actually need to be operated, and these computations are actually computing resources of a processor in the edge node that are consumed without end.
In view of this, as shown in fig. 3, an embodiment of the present invention provides a CDN function module operation method, which is applied to an edge node in a CDN, and the method may include the following steps:
s101, acquiring a request message sent by a client.
The edge node in the embodiment of the present invention may be one of nodes in a CDN network, and it can be understood that the edge node may obtain request messages sent by different clients, and the request messages sent by different clients may include different domain name information, for example, the request message sent by the client 1 carries information that a domain name is ksyun.
Specifically, the request packet may be a segment of request packet beginning with http or https and carrying information of the domain name.
In the embodiment of the invention, the edge node can be operated by adopting a Nginx-Lua system based on the OpenResty technology, wherein Nginx is a high-performance HTTP server and a reverse proxy server, Lua is a lightweight and embeddable script language, and the Lua is embedded into Nginx, so that a script program can be written by using Lua, and the technology is the OpenResty technology. In an edge node operated based on the nginnx-Lua system, when a certain function is implemented, it is usually implemented by operating a script program code, that is, the functional module in the embodiment of the present invention, and by executing the functional module, a corresponding service function is implemented.
S102, obtaining the pre-stored operation sequence of each functional module to be operated corresponding to the domain name.
After the edge node obtains the request packet sent by the client, a plurality of function modules to be operated stored in the edge node can be operated to realize different functions, and the edge node usually operates in units of domain names (host) when operating the function modules. The functional module to be operated may refer to a functional module that needs to be operated to implement a function corresponding to the domain name.
For example, if a total number of 300 functional modules are stored in one edge node, 10 functional modules may be operated for the domain name corresponding to the request packet to implement 10 functions, where the 10 functional modules are to-be-operated functional modules.
It can be understood that one edge node may receive a request packet containing information of different domain names to implement functions corresponding to the different domain names.
For example, if the domain name is ksyun.com, the request packet may be a segment of request packet beginning with http or https and carrying the domain name ksyun.com, and for the domain name ksyun.com, 10 functional modules of 300 functional modules may be operated, thereby implementing 10 functions; com, 5 of the 300 function modules may be run to implement 5 functions.
As can be seen from the above examples, the embodiments of the present invention may implement multiple functions of a domain name, for example, for a domain name ksyun.
However, before operating each functional module for the domain name, the edge node needs to determine which of all the functional modules stored therein are to-be-operated functional modules corresponding to the domain name, and an operation sequence of the to-be-operated functional modules.
For example, there are 300 functional modules stored in the edge node, where the 300 functional modules are the sum of the functional modules of all domain names, and only 10 of the domain names a may need to be run, so that only the 10 functional modules to be run need to be confirmed, and since the functional modules to be run are run according to a certain sequence, the running sequence of the functional modules to be run needs to be determined. Of course, the operating sequence may be preset.
If the existing functional module operation method is adopted, the above 300 functional modules need to be traversed and judged one by one, and these calculations are actually computing resources of processors in endless consuming edge nodes, so that the processing time of the whole CDN network is increased, which may cause delay of response content returned to the user terminal.
According to the foregoing embodiment, it can be known that different functions implemented for one domain name may correspond to different function modules, and in the embodiment of the present invention, names of function modules to be operated corresponding to the domain names and operation sequences of the function modules to be operated may be stored in advance, so that after a request packet sent by a client is acquired, the function modules to be operated of the domain name and the operation sequences of the function modules to be operated are determined directly through prestored information, without traversing switch identifiers of the function modules.
Referring to fig. 3, in S103, pre-stored configuration information of each functional module to be operated corresponding to the domain name is obtained.
In the embodiment of the present invention, the configuration information of each to-be-operated function module corresponding to the domain name may be pre-stored, for example, the edge node may read the configuration information of each to-be-operated function module corresponding to the domain name from a pre-stored second configuration file.
It can be understood that after determining the function module to be operated corresponding to the domain name, the configuration information of each function module to be operated corresponding to the domain name, which is pre-stored, may be obtained, for example, the configuration information of the network speed limit value is obtained: 100 kb/S.
And S104, operating each function module to be operated according to the operation sequence and the configuration information of each function module to be operated.
After determining the functional modules to be operated of the domain name and the operation sequence thereof and acquiring the configuration information thereof, each functional module to be operated can be operated, thereby realizing each function of the domain name.
For example, when one of the to-be-operated function modules of the domain name is a network speed limit function module, the configuration parameters stored in the configuration file may be: the network speed limit value can be used for operating the network speed limit function module.
For example, when another functional module to be operated of the domain name is an add-response head module (the response header is a part of the header field in an http request, and the operation sequence of the module is located behind the network speed limiting functional module), then the configuration parameters saved in the configuration file may be: the name of the response head and the key value are required to be added, and the response head module can be added by using the parameter operation.
As an optional implementation manner of the embodiment of the present invention, on the basis of the flow shown in fig. 3, as shown in fig. 4, the step S102 may specifically be:
s102', according to the domain names, acquiring the function linked list corresponding to the domain names from a plurality of preset function linked lists corresponding to the pre-stored domain names.
In the embodiment of the invention, the function linked lists corresponding to the domain names can be preset aiming at the domain names, and the function linked lists are prestored, so that the function linked lists corresponding to the domain names can be obtained from the prestored preset function linked lists corresponding to the domain names.
The function linked list describes an operation sequence of each function module to be operated corresponding to the domain name, wherein one function linked list may include names of Lua files corresponding to each function module to be operated, the names may be names of storage paths of the Lua files corresponding to the function modules, and the names of the Lua files corresponding to each function module to be operated may be written in according to a preset operation sequence of each function module to be operated, that is, the names of the Lua files corresponding to each function module may correspond to the preset operation sequence of each function module to be operated.
As an optional implementation manner in the embodiment of the present invention, on the basis of the flow shown in fig. 4, as shown in fig. 5, the CDN function module operation method in the embodiment of the present invention may further include:
s201, generating a second configuration file corresponding to the domain name based on the first configuration file corresponding to the edge node, and generating a function linked list corresponding to the domain name.
The edge node may have a preset first configuration file, and the configuration information in the first configuration file may be stored as a basic unit according to a domain name (host), that is, the first configuration file may store an operation sequence and configuration parameters of all the function modules, and the configuration information corresponding to different domain names may include a switch identifier for calling each function module.
It should be noted that the switch identifier may be considered as an attribute value corresponding to a function module, for example, a function module is a function module for adding a header, and the attribute may include: attribute 1 is add header; attribute 2 is the name of the header, and attribute 3 is the value of the header; attribute 1 adds a header to be considered as a switch identification for the function module.
As an optional implementation manner of the embodiment of the present invention, the configuration information belonging to different domain names may be divided by traversing the configuration information in the first configuration file, and then a second configuration file corresponding to each domain name is generated based on the divided configuration information.
And S202, storing the generated second configuration file corresponding to the domain name and the function linked list in a shared memory.
The second configuration file and the function linked list corresponding to the domain name can be stored in the shared memory, so that when a Nginx process of the edge node is started or reloaded (reloaded), the second configuration file and the function linked list which are previously stored in the shared memory cannot be deleted along with restarting or reloading, the edge node can use the second configuration file and the function linked list which are previously stored to operate the function module to be operated until the function linked list in the shared memory is updated, the situation that the configuration file and the function linked list cannot be read when the Nginx process of the edge node is started or reloaded can be avoided, and the operation stability of the edge node is improved.
Optionally, when the function linked list corresponding to the domain name is obtained from a plurality of function linked lists stored in the shared memory, the function linked list can be obtained by traversing each function linked list in the shared memory, and the speed of traversing the function linked list is faster because the number of the traversed function linked lists is less than that of traversing the switch identifiers; the domain name may also be searched from the shared memory by using the domain name as a keyword, to obtain a function linked list corresponding to the domain name, but the invention is not limited thereto.
After acquiring the function linked list corresponding to the domain name from the shared memory, the edge node can acquire the name of the Lua file of each functional module to be operated stored in the function linked list by reading the function linked list, thereby determining each functional module to be operated of the domain name.
In the embodiment of the present invention, as shown in fig. 6, the step of generating the function linked list specifically includes:
s2011, searches for a preset identifier in a second configuration file corresponding to the domain name.
In the embodiment of the present invention, an identifier may be added to each functional module in advance in the second configuration file, for example: the identifier may be a key attribute value of the function module, and the key attribute value may be considered as a switch for calling the function module, for example, in an attribute corresponding to one function module, attribute 1 is to add a header to the function module; attribute 2 is the name of the header, and attribute 3 is the value of the header; and adding a header as the key attribute value of the functional module, so that after the edge node finds the identifier (key attribute value) in the second configuration file corresponding to the domain name, the functional module corresponding to the edge node can be determined to be to-be-operated.
And S2012, determining the name of the Lua file corresponding to the searched preset identifier in a preset function mapping table.
Because the corresponding relationship between the preset identifier and the Lua file can be stored in the preset function mapping table, after the preset identifier is found in the above step, the name of the Lua file corresponding to the preset identifier can be further found in the function mapping table.
And S2013, writing the determined names of the Lua files into the function linked list corresponding to the domain name according to the operation sequence of the function modules corresponding to the Lua files to obtain the function linked list corresponding to the domain name.
After the operation sequence of the function modules corresponding to the Lua files is determined, the names of the Lua files of the function modules corresponding to the domain name can be written into the function linked list corresponding to the domain name based on the determined operation sequence, that is, the function linked list corresponding to the current domain name has recorded therein: the names of the Lua files of the functional modules corresponding to the domain name and the recorded names of the Lua files carry the running sequence information of the functional modules, that is, the functional modules to be run corresponding to the domain name and the running sequence of the functional modules to be run can be determined according to the names of the Lua files and the positions of the names of the Lua files in the function linked list.
As an optional implementation manner in the embodiment of the present invention, when the function linked list is established, names of the function linked lists may be named as the same as domain names, for example, the function linked list corresponding to the domain name a may be directly named as the function linked list a, so that a corresponding relationship between the function linked list and the domain names is established. Of course, in addition to the implementation manners shown in the illustrated examples, the manners of implementing the features of establishing the correspondence between the function linked list and the domain name are all within the protection scope of the embodiment of the present application.
As an optional implementation manner of the embodiment of the present invention, the establishing process of the function mapping table may be:
when the Nginx process of the edge node is started or reloaded, the identifiers (key attribute values) of all the functional modules are obtained from the second configuration file, the corresponding relation is established between each identifier and the Lua file name of each functional module, and the established corresponding relation is stored in a form of a table 1.
Table 1 contents of function mapping table
As an optional implementation manner of the embodiment of the present invention, a second configuration file corresponding to a domain name may be obtained from second configuration files of the domain names stored in a shared memory, and configuration information of each function module to be operated corresponding to the domain name is read, so that the reading speed of the configuration information is increased by using the characteristic of high memory read-write performance.
