Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The Nginx shared memory can store configuration data of different service scenes, and the Nginx can realize services such as system current limiting, malicious user filtering, load balancing and the like according to the configuration data stored in the shared memory. Along with the change of the service requirement, the configuration data in the shared memory needs to be correspondingly adjusted. The prior art typically updates the configuration data in the shared memory manually and then restarts ng the ng x to validate the configuration data.
Since the nginnx needs to be restarted, it takes a long time to update the configuration data in the prior art, thereby affecting the processing of corresponding services by the nginnx.
In view of this, an embodiment of the present invention provides a method for updating configuration data, as shown in fig. 1, including:
And 101, acquiring a configuration update message according to the connection between the pre-established ZooKeeper client and the ZooKeeper server.
When the stored configuration data is updated, the ZooKeeper server can push a configuration update message to the ZooKeeper client. The configuration update message may include an identification of the configuration item under the update path. The configuration update message may further include information such as an identification of the update configuration item, an update type, and a value of the configuration item under the update path. The identification of the configuration item may be the name or number of the configuration item, etc.
In order to ensure the stability of the service, in an actual application scene, the ZooKeeper client interacts with a server on the ZooKeeper server cluster.
Step 102, determining an update configuration item and an update type according to the configuration update message.
The configuration update message may include an update type, which may also be determined based on changes in the configuration items before and after the update. The update configuration item may be one item or a plurality of items. The update type comprises configuration item addition, configuration item modification, configuration item deletion and the like. For example, if the update configuration item is a and the update type is delete, then a in the nginnx shared memory is deleted. If the update configuration item is B and the update type is increased, B is increased in the Nginx shared memory. If the update configuration item is C and the update type is modification, modifying C in the Nginx shared memory.
And 103, updating the configuration data in the Nginx shared memory according to the update configuration item and the update type thereof.
After the configuration data in the ZooKeeper server is updated, the ZooKeeper client can timely and quickly acquire the configuration update message, update the configuration data in the Nginx shared memory based on the configuration update message, and the updated configuration data can be immediately used for service processing without restarting the Nginx. Therefore, the embodiment of the invention can shorten the time spent in the updating process and improve the processing efficiency of the business data.
In one embodiment of the invention, the method further comprises:
obtaining ZooKeeper configuration information;
And calling the ZooKeeper client to enable the ZooKeeper client to be connected with the ZooKeeper server according to the ZooKeeper configuration information.
The ZooKeeper configuration information includes a ZooKeeper service cluster host, port information, a directory path of configuration data, and the like.
The ZooKeeper client can establish connection with the ZooKeeper server according to the ZooKeeper service cluster host and the port information, and obtain the configuration data in the ZooKeeper server through the directory path of the configuration data.
After the ZooKeeper client is connected with the ZooKeeper server, the function address for processing the configuration update message can be specified, and after the ZooKeeper client receives the configuration update message pushed by the ZooKeeper server, the configuration update message is put into the specified function address to trigger the processing of the subsequent configuration update message.
According to the embodiment of the invention, the ZooKeeper client is connected with the ZooKeeper server by calling the ZooKeeper client, so that the configuration data in the ZooKeeper server can be conveniently and rapidly stored in the shared memory.
After the ZooKeeper configuration information is obtained, before the ZooKeeper client is called, the method can further comprise verifying whether the ZooKeeper configuration information meets the preset configuration condition, if so, executing the call of the ZooKeeper client, otherwise, terminating the current flow. The configuration condition may be that the ZooKeeper configuration information includes a ZooKeeper service cluster host and port information, and the configuration condition may also be that the ZooKeeper configuration information includes a ZooKeeper service cluster host, port information and a directory path of configuration data.
In one embodiment of the present invention, after invoking the ZooKeeper client, before acquiring the configuration update message, the method further comprises:
Acquiring configuration data in a ZooKeeper server through a ZooKeeper client;
and writing configuration data obtained from the ZooKeeper server into the Nginx shared memory.
Before updating the configuration data in the Nginx shared memory, the existing configuration data in the ZooKeeper server needs to be written into the Nginx shared memory, so that the subsequent business processing is ensured to be smoothly carried out.
In the embodiment of the invention, the configuration data of all the configuration packets in the WATCHPATH directory are read and stored in the memory in Hashmap, HASHMAP KEY is the name of the configuration item, and value is the configuration value.
WATCHPATH catalogue is as follows:
the WATCHPATH directory is a directory path configured in the configuration information, the next level is a grouping node of the configuration data, and the next level of the grouping node is actual configuration data.
HASHMAP KEY is config1, and the corresponding value is the configuration value of config 1. config1, config2, and config3 may filter, load balance, and request routing traffic for malicious users, respectively.
Compared with the method for manually writing the existing configuration data in the ZooKeeper server into the Nginx shared memory, the embodiment of the invention does not need to restart the Nginx and does not influence the service processing process.
In one embodiment of the invention, the method further comprises:
Generating configuration data structure information according to configuration data in a ZooKeeper server, wherein the configuration data structure information comprises identifiers of paths and configuration items under the paths;
The configuration update message comprises an update path and an identifier of a configuration item under the update path;
determining an update configuration item and an update type thereof according to the configuration update message, including:
and determining the identification of the update configuration item and the update type thereof according to the update path, the identification of the update configuration item under the update path and the identification of the configuration item under the path.
The configuration data structure information has the structure that:
the hash_map < string, set < string > >, the outer hash_map structure key is the path, and the value is the identification of all configuration items contained in the path.
For example, the content stored under the/WATCHPATH/configGroup 1 directory is,
key:/watchPath/configGroup1
Value, set containing two string members of config1 and config 2.
For example, the configuration data structure information before update, that is, the directory structure of the configuration data in the ZooKeeper server before update is:
The configuration update message comprises that the update path is/WATCHPATH/configGroup 1, and the identifier of the configuration item under the update path is config2. As can be seen from the configuration update message,/WATCHPATH/conf igGroup1, the configuration items are updated, and the identifiers of the configuration items config1 are absent after the update by comparing the identifiers of the configuration items before and after the update with the identifiers of the configuration items WATCHPATH/configGr oup, so that the update operation is to delete the configuration items config1.
If the identifiers of the configuration items under the update path are config1, config2, and config4, the update operation is to add the configuration item config4.
If the identifiers of the configuration items under the update path are config1 and config2, the update operation is to modify the configuration items config1 and config2, that is, if the identifiers of the configuration items under the update path have not changed, the values of the respective configuration items under the update path are modified.
The embodiment of the invention determines which change happens to the configuration item under which path through the configuration data structure information, can reduce the number of data transmission between the ZooKeeper client and the ZooKeeper server and the times that the ZooKeeper client accesses the ZooKeeper server, and simultaneously quickens the updating efficiency of the configuration data.
It should be noted that, in the actual application scenario, the identification of the update configuration item and the update type thereof may not be determined through the configuration data structure information. At this time, the configuration update message may include information such as an update type, an update path, and an identification of an update configuration item.
In one embodiment of the invention, if the update type is a configuration item modification, the method further comprises:
acquiring an update configuration value of an update configuration item in a ZooKeeper server through a ZooKeeper client;
updating the configuration data in the Nginx shared memory according to the update configuration item and the update type thereof, wherein the updating comprises the following steps:
and modifying the configuration value of the update configuration item in the Nginx shared memory into an update configuration value.
Along the above example, if configGroup a is modified, updating the configuration items to be config1 and config2, and obtaining the values of the configuration items config1 and config2 updated in the ZooKeeper server, namely the updated configuration values of config1 and config 2. Since the modification does not involve a change in the configuration data structure information, the embodiment of the present invention does not require updating the configuration data structure information.
In one embodiment of the present invention, if the update type is a configuration item delete, the method further comprises:
deleting the identification of the update configuration item under the update path in the configuration data structure information;
updating the configuration data in the Nginx shared memory according to the update configuration item and the update type thereof, wherein the updating comprises the following steps:
and deleting the identification and the configuration value of the updated configuration item in the Nginx shared memory.
Along the above example, after deleting the update configuration item config1, the configuration data structure information is changed to:
timely changing the configuration data structure information can ensure the accuracy and reliability of the subsequent updating configuration data.
In one embodiment of the present invention, if the update type is a configuration item addition, the method further comprises:
acquiring an update configuration value of an update configuration item in a ZooKeeper server through a ZooKeeper client;
adding an identifier of an update configuration item under an update path in the configuration data structure information;
updating the configuration data in the Nginx shared memory according to the update configuration item and the update type thereof, wherein the updating comprises the following steps:
And adding the identification of the update configuration item and the update configuration value into the Nginx shared memory.
Along the above example, if the update configuration item is config4 and the update type is configuration item increment, the configuration data structure information is changed to:
Similar to the deletion of the configuration item, the configuration data structure information needs to be adjusted in time after the configuration item is added to prevent errors in the subsequent update type and determination of the updated configuration item.
As shown in fig. 2, an embodiment of the present invention provides a method for updating configuration data, including:
step 201, obtaining ZooKeeper configuration information.
And 202, calling the ZooKeeper client so that the ZooKeeper client is connected with the ZooKeeper server according to the ZooKeeper configuration information.
And 203, acquiring configuration data in the ZooKeeper server through the ZooKeeper client.
And 204, writing configuration data obtained from the ZooKeeper server into the Nginx shared memory.
And 205, generating configuration data structure information according to configuration data in the ZooKeeper server, wherein the configuration data structure information comprises identifiers of paths and configuration items under the paths.
And 206, acquiring a configuration update message according to the connection between the ZooKeeper client and the ZooKeeper server, wherein the configuration update message comprises an update path and an identifier of a configuration item under the update path.
Step 207, determining the identity of the updated configuration item and the update type thereof according to the identity of the updated path, the identity of the configuration item under the updated path and the identity of the configuration item under the path, if the update type is the modification of the configuration item, executing step 208, if the update type is the deletion of the configuration item, executing step 209, and if the update type is the addition of the configuration item, executing step 210.
Step 208, obtaining the update configuration value of the update configuration item in the ZooKeeper server through the ZooKeeper client, and modifying the configuration value of the update configuration item in the Nginx shared memory into the update configuration value.
Step 209, deleting the identifier of the update configuration item under the update path in the configuration data structure information, and deleting the identifier and the configuration value of the update configuration item in the Nginx shared memory.
Step 210, obtaining an update configuration value of an update configuration item in the ZooKeeper server through the ZooKeeper client, adding an identifier of the update configuration item under an update path in configuration data structure information, and adding the identifier of the update configuration item and the update configuration value into the Nginx shared memory.
The embodiment of the invention updates the configuration data in the Nginx shared memory based on the ZooKeeper service without restarting the Nginx, and can reduce the influence of the configuration data update process on the business processing process. In addition, the embodiment of the invention can rapidly determine the update type based on the configuration data structure information, thereby improving the update efficiency of the configuration data and ensuring the update accuracy.
As shown in fig. 3, an embodiment of the present invention provides an apparatus for updating configuration data, including:
The configuration management module 301 is configured to obtain a configuration update message according to the connection between the pre-established ZooKeeper client and the ZooKeeper server;
The configuration updating module 302 is configured to update the configuration data in the nginnx shared memory according to the update configuration item and the update type thereof.
In one embodiment of the present invention, the configuration management module 301 is configured to obtain ZooKe eper configuration information, and call the ZooKeeper client to make the ZooKeeper client connect to the ZooKeeper server according to Zoo Keeper configuration information.
In one embodiment of the present invention, the configuration management module 301 is configured to obtain configuration data in the ZooKeeper server through the ZooKe eper client, and write the configuration data obtained from the ZooKeeper server into the nginnx shared memory.
In one embodiment of the present invention, the configuration management module 301 is configured to generate configuration data structure information according to the configuration data in the ZooKe eper server, where the configuration data structure information includes identifiers of paths and configuration items under the paths, and determines the identifiers of the update configuration items and the update types thereof according to the update paths, the identifiers of the configuration items under the update paths, and the identifiers of the configuration items under the paths.
In one embodiment of the present invention, if the update type is a configuration item modification, the configuration management module 301 is configured to obtain, by the ZooKeeper client, an update configuration value of an update configuration item in the ZooKeeper server;
The configuration updating module 302 is configured to modify the configuration value of the update configuration item in the nginnx shared memory into an update configuration value.
In one embodiment of the present invention, if the update type is a configuration item deletion, the configuration management module 301 is configured to delete the identifier of the update configuration item under the update path in the configuration data structure information;
the configuration update module 302 is configured to delete the identifier and the configuration value of the updated configuration item in the nginnx shared memory.
In one embodiment of the present invention, if the update type is that the configuration item is added, the configuration management module 301 is configured to obtain, through the ZooKeeper client, an update configuration value of the update configuration item in the ZooKeeper server;
The configuration update module 302 is configured to add the identification of the update configuration item and the update configuration value to the nginnx shared memory.
After the start-up, there are multiple independent Nginx workbench processes. The nmginx Worker process invokes the configuration management module 301 and the configuration update module 302, respectively, to implement updating of the configuration data.
Specifically, the nmginx Worker process loads the configuration management module 301 under OpenResty framework using the following statements:
lua_package_cpath"/export/soPath/configCenter.so;;"。
As shown in fig. 4, the configuration management module 301 sends an update configuration item and an update type thereof to the configuration update module 302 through an HTTP request, and the configuration update module 302 updates the configuration data in the nginnx shared memory according to the update configuration item and the update type thereof. In the practical application scenario, the configuration management module 301 and the configuration update module 302 run in the LuaJIT virtual machine in two threads, and since the LuaJIT virtual machine does not support multi-thread running, the HTTP protocol must be used to communicate between the configuration management module 301 and the configuration update module 302, if the communication is forced between the two threads directly, the nmginx Worker process is crashed, which causes an online accident.
As shown in fig. 4, nmginx is generally in a multi-process mode, and when the system is started, a plurality of nmginx Worker processes will perform initialization processing simultaneously, so that synchronization is required by using a security. Specifically, the nmginx Worker first determines whether a mark corresponding to the nmginx Worker exists in the shared memory, if the mark does not exist in the shared memory, then acquires the synchronous lock, loads the configuration management module, adds the mark in the nmginx shared memory after the configuration management module completes the initialization flow, so as to identify that the nmginx Worker completes the initialization of the configuration management module, and finally releases the synchronous lock. After the nmginx Worker releases the synchronization lock, other nmginx workers blocked by the lock can execute the initialization flow.
The configuration management module comprises the steps of establishing connection between a ZooKeeper client and a ZooKeeper server, acquiring configuration data in the ZooKeeper server through the ZooKeeper client, writing the configuration data acquired from the ZooKeeper server into an Nginx shared memory, and generating configuration data structure information according to the configuration data in the ZooKeeper server.
As shown in fig. 4, N nminbx Worker processes are obtained after nminbx is started, and a configuration management module and a configuration update module can be run in each nminbx Worker process. In fig. 4, only one nmginx Worker process runs the configuration management module and the configuration update module, and because the nmginx Worker process can update the configuration data in the nmginx shared memory, other nmginx Worker processes can share the updated configuration data and execute service logic based on the updated configuration data, so as to realize a corresponding service flow.

One or more processors;
Storage means for storing one or more programs,
The one or more programs, when executed by the one or more processors, cause the one or more processors to implement the methods of any of the embodiments described above.
