Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for updating configuration of a DNS server, a terminal device, and a configuration updating system.
Background
A Content Delivery Network (CDN) is a one-layer intelligent virtual Network based on the existing internet, which is formed by placing node servers at various locations of the Network, so that a CDN system can redirect a user's request to a service node closest to the user in real time according to Network traffic, connection of each node, load conditions, and comprehensive information such as a distance to the user and response time. When providing network acceleration service, a CDN service provider often needs to change and timely process a policy of providing service according to factors such as a special requirement of a user, a state of a server, or own cost. For example: 1. when the bandwidth of an exit of a server at a certain node is too high, the phenomena of time delay, packet loss and the like occur when a user accesses the node, so that the service quality is reduced, and the bandwidth of the node with the too high bandwidth is reduced because the ip of a backup node needs to be searched to carry the bandwidth of the node with the too high bandwidth; 2. when a user in a certain area accesses, the user can provide the specified node for service, so that the purposes of reducing cost and improving service quality are achieved.
How to improve the efficiency of updating the configuration file becomes a key problem for providing high-quality service under the condition that the scheduling strategy needs to be changed in time.
In the prior art, an adjustment scheme for a scheduling policy is implemented, in which a central server monitors the status of a server providing a service in real time, calculates the status to generate a corresponding scheduling policy, converts the scheduling policy to be adjusted into a bind configuration file, and sends the bind configuration file to each DNS server. And the update configuration cannot be issued in time, so that the service quality is reduced, and the user experience is not high. The prior art has the following defects:
1. the central server needs to perform a large amount of calculation, converts the original monitoring data into configuration files which can be identified by the bind, and then issues the configuration files to each DNS server, so that the configuration files need to contain modification strategies which are in line with the needs of all DNS servers, the configuration files are too large, the issuing time is too long, and the load of the central server is increased.
2. Due to the fact that the time for sending is too long, the operation failure rate of the configuration file which needs to be changed frequently is greatly improved, and user experience is affected.
3. When a DNS server is newly deployed, the DNS server needs to download a complete configuration file to the central server, and when a plurality of DNS servers request simultaneously, the central server is under excessive pressure, so that the download time of the configuration file is too long.
4. In the prior art, if the central server is in a configuration issuing state, the configuration file updated subsequently cannot be issued, so that the configuration file cannot be changed urgently in case of an emergency.

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.
The first embodiment of the present invention:
referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart of an embodiment of a method for configuration update of a DNS server provided in the present invention, and fig. 2 is a schematic structural diagram of an embodiment of a configuration update system provided in the present invention. The configuration updating system in the embodiment of the invention comprises a central server and a plurality of DNS servers administered by the central server, wherein each DNS server provides domain name resolution service for a network region; the configuration updating system runs hex distributed software and is divided into a center part and an edge part, a center server runs a hex center, and a DNS server runs a hex edge. For a network user in a network area, such as a mobile device user, a PC end user, etc., accessing a DNS server in the network area, the DNS server converts a name provided by the network user into a network address, such as an IP address, and returns the network address to the network user, and the network user accesses a corresponding node server according to the returned network address. The local configuration file stored in the DNS server for converting the name provided by the network user into the network address is issued and configured by the central server. Therefore, based on the update request of the configuration update of the DNS server, an embodiment of the present invention provides a method for updating the configuration of the DNS server, which is executed by a central server, and specifically includes the following steps:
and S10, receiving basic configuration data of the monitoring node server of the whole network.
In the embodiment of the invention, a resource platform monitors node servers of the whole network, the resource platform can automatically generate original access data according to the monitoring process, and can also add manual configuration, so that the original access data is a set of basic configuration data of each region, and one basic configuration data records a scheme that one or more DNS servers selected by the node servers in one network region provide domain name resolution service and a scheme that users in the network region can selectively access the node servers according to the identity attributes of the users. Because the original access data is the planned basic configuration data, the central server is not required to calculate and generate the basic configuration data for configuring the DNS server, and the load of the central server is reduced.
The basic configuration data provided in the embodiment of the present invention includes, but is not limited to, the contents in the following table, and may be sent to a DNS server of a large area corresponding to the basic configuration data in a file format, for example, the following table is taken as an example, the large area a may include, but is not limited to, an area a, an area b, and an area c, and the large area and the area are network areas; the basic configuration data records data of node servers contained in the cache1 and the cache2, when the identity attribute of the user is operator 1 and is area a, the node servers accessible by the user are the cache 1; the cache1 and the cache2 both comprise a plurality of node servers. Therefore, when a user accesses a DNS server of a large area, the DNS server determines a node server which can be accessed by the user according to the identity attribute of the user and returns the information to the user so that the user can log in the corresponding node server.
S20, monitoring the update request for updating the configuration of the DNS server managed by the central server.
In the embodiments of the present invention, in general, the following occurs: firstly, when the bandwidth of an exit of a certain node server is too high, the phenomena of time delay, packet loss and the like occur when a user accesses the node, so that the service quality is reduced, and the bandwidth of the node with the too high bandwidth is reduced because the ip of a backup node needs to be searched to carry the bandwidth of the node with the too high bandwidth; secondly, a certain area needs to be assigned with a specific node for service, and when a user in the area accesses the area, the user can provide the assigned node for service, so that the purposes of reducing cost and improving service quality are achieved; and the central server updates the configuration of the DNS server managed by the central server, namely the central server receives an updating request.
S30, responding to the update request, and issuing basic configuration data and deployment notification corresponding to each network area to the DNS server of each network area; the deployment notification is used for notifying the DNS server to perform deployment updating operation according to the basic configuration data received by the DNS server; the deployment update operation includes the DNS server converting the base configuration data into a reference configuration file that the DNS server can identify containing a set of secondary domain name resolutions.
In the embodiment of the invention, the basic configuration data required by the DNS server is only issued to the DNS server in each network area, so that the issued data volume is greatly reduced, and the issuing speed is increased; and the operation of converting the base configuration data into a reference configuration file that is recognizable by the DNS server and contains a set of secondary domain name resolutions is performed by the DNS server, com is a secondary domain name, on the one hand, to reduce the load on the central server, and, on the other hand, to include a plurality of secondary domain name resolution groups, e.g. cdn.com, by classifying customers (by service type, country, etc.), the same type of customers are classified into the same CDN acceleration secondary domain name, which is CNAME to the assigned acceleration secondary domain name, i.e., one resolution group corresponds to the same class of customer domain names, while the file size of one resolution group is almost equal to the file size of one underlying configuration data, therefore, the basic configuration data is reduced by multiple times compared with the file size of the converted reference configuration file, and the issuing speed can be further improved.
In the embodiment of the invention, the format of the reference configuration file is a bind format configuration file and can be identified by bind software built in a DNS.
In summary, the present invention provides a method for updating configuration of DNS servers, where a central server can directly obtain original access data of monitoring node servers in a whole network from a resource platform, and because the original access data comprises the basic configuration data of the domain name resolution service provided by the DNS server selected by the node server in each network region, a central server is not required to perform a large amount of calculation, the load of the central server is reduced, on the other hand, when an update request for a configuration update to a DNS server administered by the central server is monitored, issuing basic configuration data and deployment notification corresponding to each network area to a DNS server of the network area, because the data is only configured to the DNS server of each network region, the data volume of the distribution is greatly reduced, and the distribution speed is improved; and the operation of converting the basic configuration data into the reference configuration file which can be identified by the DNS server and contains the secondary domain name resolution group is executed by the DNS server instead of the central server, so that the load of the central server is reduced on one hand, and on the other hand, the issuing speed can be further improved because the size of the basic configuration data is reduced by multiple times compared with the file size of the converted reference configuration file.
Second embodiment of the invention:
on the basis of the first embodiment, the issuing of the basic configuration data and the deployment notification corresponding to each network area to the DNS server of each network area specifically includes:
and after receiving the information of successful test deployment operation, issuing basic configuration data and a deployment notification corresponding to each network area to a DNS (domain name server) of each network area. When the update request is responded, the DNS server is tested and deployed successfully, and then the deployment operation of the whole network is executed, so that the condition that the DNS server of the whole network is paralyzed due to the fact that the update is directly issued by the whole network when the basic configuration data to be issued have errors is avoided. And after the test deployment operation is successful, the deployment operation of the whole network is executed after the basic configuration data to be issued is proved to have no problem.
Preferably, the test deployment operation is executed by the central server, and specifically includes:
sending basic configuration data and test deployment notification corresponding to a network area to which the DNS server belongs to at least N DNS servers in the whole network; the test deployment notification is used for notifying the DNS server to perform deployment updating operation according to the basic configuration data received by the DNS server, and returning the information of successful test deployment operation to the central server after successful deployment.
Preferably, N is equal to or greater than 3. In the embodiment of the invention, the whole network deployment is executed after the N DNS servers all return the information of successful test deployment operation. The embodiment of the invention can effectively improve the success rate of the deployment and update operation of the DNS server.
In the embodiment of the present invention, the selection of the N DNS servers may be that N servers closest to the central server are selected from all DNS servers governed by the central server, so as to improve the efficiency of the test deployment operation; the method can also be used for selecting N DNS servers with the largest DNS server load from all DNS servers governed by the central server, and if the N servers with the largest load are successfully deployed and updated and can complete the pressure test, the success rate of deployment and update of other DNS servers with smaller load is higher; or the N DNS servers with the largest load quantity are selected from the DNS servers which have not been subjected to the test deployment operation within a period of time set by history, so that the success rate of the DNS servers for performing the deployment updating operation can be further ensured.
Third embodiment of the invention:
on the basis of the first embodiment or the second embodiment, the method for providing configuration update according to the embodiment of the present invention further includes:
distributing basic configuration data in the original access data to a task issuing queue of a corresponding network area; the basic configuration data has the attribute of issuing priority;
and responding to the updating request, and extracting the basic configuration data with the highest issuing priority from each task queue as the basic configuration data to be issued.
Specifically, each piece of basic configuration data is used as a task, and has a version number, and the task with the highest version number has the highest issuing priority. When a plurality of tasks exist in a task queue of the same network area, the task being issued is not interrupted, only the basic configuration data with the highest version number, namely the priority, is issued to the DNS server of the network area, and other tasks (namely the basic configuration data) are discarded.
Fig. 3 is a schematic diagram of a flow for executing configuration update distribution by the central server according to the present invention. Taking the original access data acquired by the central server from the resource platform as an example, the configuration issuing process of the central server is described as follows:
step A1: the central server acquires original access data from the resource platform;
step A2: the central server performs file inspection on basic configuration data in the original access data;
step A3: the central server distributes the basic configuration data to a task issuing queue of a corresponding network area;
step A4: when an updating request is received, judging whether the task queue executes a task which issues basic configuration data or the task queue is empty; if yes, go to step A9; if not, executing the step A5;
step A5: taking out the basic configuration data with the highest issued priority level from the task queue;
step A6: compressing the extracted basic configuration data;
step A7: sending the compressed basic configuration data to a DNS server of a corresponding network area;
step A8: sending a deployment notification to the DNS server which has issued the basic configuration data and returning to the step A4;
step A9: the central server quits working.
On the basis of the above embodiment, preferably, the deployment updating operation further includes that the DNS server updates data in the local configuration file that is different from the reference configuration file to corresponding data in the reference configuration file.
Referring to fig. 4, a schematic flowchart of the DNS server executing the deployment update operation provided by the present invention is shown. When the DNS server receives a deployment notification or a test deployment notification from the central server, the process of the deployment update operation of the DNS server is described by taking the received basic configuration data as an example, specifically as follows:
step B1: the DNS server receives a deployment notification or a test deployment notification from the central server and inquires whether basic configuration data are received; if yes, go to step B3; if not, go to step B2.
Step B2: and the DNS server requests the central server to download the basic configuration data, and checks the basic configuration data until the checking is successful. The specific verification process comprises: and checking the validity of the IP of the central server, and eliminating the server IP with faults and the file sent by the server with incomplete regional information.
Step B3: the DNS server decompresses the compressed packets of the base configuration data.
Step B4: and the DNS server generates a reference configuration file which can be identified by the bind according to the decompressed basic configuration data.
Step B5: the DNS server performs a syntax check on the reference profile.
Step B6: after the grammar check is passed, the DNS server carries out differential updating on the local configuration file; the differential updating refers to updating data which is different from the reference configuration file in a local configuration file into corresponding data in the reference configuration file. Since only the changed files are updated, the speed of reloading the local configuration files by the subsequent bind is increased.
Step B7: the DNS controls bind software to reload the local configuration file; this enables the modified local profile to be successfully re-run in the DNS server.
Step B8: the DNS server executes dig check and returns the information of successful deployment to the central server after the check is successful.
And in the embodiment of the invention, as long as one step of the flow fails to be executed, the flow quits and returns the information of failed deployment to the central server.
