Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
In order to implement dynamic update of load balancing backend Server (RS) information, reduce update cost of RS information, and improve update efficiency of RS information, an embodiment of the present application provides an RS information update method, including:
receiving update request information of RS information of a load balancing background server, wherein the RS information is stored in a shared memory;
and updating the RS information corresponding to the update request information in the shared memory through the target process receiving the update request information.
Therefore, the RS information updating method provided by the embodiment of the application can receive the updating request information of the RS information, wherein the RS information is stored in the shared memory; and updating the RS information corresponding to the update request information in the shared memory through the target process receiving the update request information. The RS information can be dynamically updated, the updating cost of the RS information is reduced, and the updating efficiency of the RS information is improved.
Referring to fig. 1, fig. 1 is a flowchart of an RS information updating method according to an embodiment of the present application, including:
and step S11, receiving the update request information of the RS information of the load balancing background server.
Wherein, the RS information is stored in the shared memory. In a seven-layer load balancing forwarding mechanism represented by Nginx, the RS information in the upstream module can be accessed by all worker processes. Wherein the update request information may include the upstream name and the new RS list.
The RS information updating method of the embodiment of the application aims at the RS information in the intelligent terminal device, so that the RS information can be executed through the intelligent terminal device, and specifically, the intelligent terminal device can be a computer or a server and the like.
Step S12, the RS information corresponding to the update request information is updated in the shared memory by the target process that receives the update request information.
The RS information is stored in the shared memory, and all worker processes can access the RS information stored in the shared memory. The RS information corresponding to the update request information is updated in the shared memory through the target process receiving the update request information, and the RS information corresponding to the update request information can be updated through the target process receiving the update request information, a new process or a current process such as a target process. For example, a worker process in the Nginx receives the update request information of the RS information, analyzes the content of the update request information of the RS information, and updates the RS information on the shared memory.
Because the worker process acquires the RS information from the shared memory, the RS information corresponding to the updating request information is updated in the shared memory through the target process for receiving the updating request information, and the real-time sharing of the RS information among all worker processes can be ensured.
Therefore, the RS information updating method provided by the embodiment of the application can receive the updating request information of the RS information, wherein the RS information is stored in the shared memory; and updating the RS information corresponding to the update request information in the shared memory through the target process receiving the update request information. The RS information can be dynamically updated, the updating cost of the RS information is reduced, and the updating efficiency of the RS information is improved.
Optionally, referring to fig. 2, fig. 2 is a flowchart of a method for storing RS information in a shared memory according to an embodiment of the present application, where before receiving an update request message of the RS information, the method further includes:
step S21, when the reverse proxy server is started, a shared memory is established.
The shared memory may be a segment of storage space in the server memory, and information in the storage space may be read by any process.
In step S22, the RS information is stored in the shared memory.
When the reverse proxy server is started, a shared memory is established, and the RS information is stored in the shared memory. A monitoring module can be added in the Nginx to monitor the RS state change, when the Nginx is started, a shared memory is created and used for storing the RS information, and all worker processes can read the RS information in the shared memory.
Therefore, when the reverse proxy server is started, a shared memory is established; and storing the RS information into the shared memory. The RS information in the shared memory can be read by any process in the server.
Optionally, referring to fig. 3, fig. 3 is a flowchart of a method for locking RS information according to an embodiment of the present application, where before updating, in a shared memory, RS information corresponding to update request information through a target process that receives the update request information, the method further includes:
step S31, the RS information corresponding to the update request information is searched.
The update request information may be the RS information corresponding to the update request information, which is obtained by analyzing the update request information. For example, a worker process in the Nginx receives the update request information of the RS information, analyzes the content of the update request information of the RS information, and searches for the corresponding RS information on the shared memory according to the content of the update request information of the RS information.
Step S32, it is determined whether the RS information corresponding to the update request information is in a read-write state.
The RS information corresponding to the update request information is determined whether to be in a read-write state, and the RS information corresponding to the update request information may be read-written for determining whether any process exists.
In step S33, if the RS information corresponding to the update request information is not in a read-write state, the RS information is locked.
And locking the RS information comprises forbidding any process except the target process to read and write the RS information. Therefore, error information generated by the RS information out of synchronization and integrity can be prevented from being updated when a process acquires the RS information.
After the RS information corresponding to the update request information is updated in the shared memory by the target process receiving the update request information, the method further includes:
step S34, unlock the RS information.
Therefore, by the method for locking the RS information, the RS information corresponding to the update request information can be searched, and the RS information is locked, wherein the locking of the RS information comprises prohibiting any process except the target process from reading and writing the RS information. Therefore, error information generated when the RS information is not synchronized completely in the process of acquiring the RS information updating by a process is prevented.
Optionally, referring to fig. 4, fig. 4 is a flowchart of an updating method for RS information in a read-write state according to an embodiment of the present application, and after determining whether RS information corresponding to update request information is in the read-write state, the method further includes:
step S35, if the RS information corresponding to the update request information is in a read-write state, after waiting for a preset duration, re-determining whether the RS information corresponding to the update request information is in a read-write state.
Therefore, by the method for locking the RS information, whether the RS information corresponding to the update request information is in the read-write state can be judged again when the RS information corresponding to the update request information is in the read-write state. Therefore, error information generated when the RS information is not synchronized completely in the process of acquiring the RS information updating by a process is prevented.
Optionally, referring to fig. 5, fig. 5 is a flowchart of a method for periodically updating RS information according to an embodiment of the present application, where update request information of the RS information is sent through a pre-established control center, and the method further includes:
step S41, comparing the RS information stored in the control center with the RS information in the shared memory according to the preset time interval.
The preset time interval can be any time interval, the RS information stored in the control center and the RS information in the shared memory are compared, and the RS information stored in the control center and the RS information in the shared memory can be compared through the control center and timing control.
And step S42, when the difference information between the RS information stored in the control center and the RS information in the shared memory is larger than a preset threshold value, updating the RS information in the shared memory according to the RS information stored in the control center.
In order to ensure the consistency of the RS information in the shared memory and the RS information of the control center, a timing task is required to be set, a list of the RS of the control center is obtained at regular time, and if the difference information between the data in the shared memory and the RS list of the control center is larger than a preset threshold value, the RS in the shared memory is updated. And the worker process and the control center data are synchronized. Wherein the threshold value may be any value, e.g. 0%, i.e. updated when there is a discrepancy. For example, referring to fig. 6, fig. 6 is a diagram illustrating an example of a timing update of RS information according to an embodiment of the present application, where an update request of RS information sent by a control center is sent to a work process, and RS information of a shared memory is updated by acquiring/updating the RS information.
Therefore, by the method for locking the RS information, the RS information stored in the control center and the RS information in the shared memory can be compared according to the preset time interval, and when the difference information between the RS information stored in the control center and the RS information in the shared memory is larger than the preset threshold value, the RS information in the shared memory is updated according to the RS information stored in the control center. Therefore, the consistency of the RS information stored in the control center and the RS information in the shared memory is ensured, and the real-time effectiveness of the RS information in the shared memory is ensured.
Optionally, referring to fig. 7, fig. 7 is a flowchart of a RS information obtaining method according to an embodiment of the present application, where after the target process that receives the update request information updates RS information corresponding to the update request information in the shared memory, the method further includes:
step S51, receiving the request information of the RS information of the load balancing backend server, and acquiring updated RS information in the shared memory corresponding to the request information through a preset process.
Therefore, by the method of the embodiment of the application, the request information of the RS information of the load balancing background server can be received after the RS information corresponding to the update request information is updated in the shared memory through the target process for receiving the update request information, and the updated RS information in the shared memory corresponding to the request information is obtained through the preset process. Therefore, the updated RS information is obtained from the shared memory, and the use of the RS information is ensured.
Referring to fig. 8, fig. 8 is another flowchart of an RS information updating method according to an embodiment of the present application, including:
and step S11, receiving the update request information of the RS information of the load balancing background server.
Wherein, the RS information is stored in the shared memory.
Step S31, the RS information corresponding to the update request information is searched.
Step S32, it is determined whether the RS information corresponding to the update request information is in a read-write state.
In step S33, if the RS information corresponding to the update request information is not in a read-write state, the RS information is locked.
And locking the RS information comprises forbidding any process except the target process to read and write the RS information.
Step S35, if the RS information corresponding to the update request information is in a read-write state, after waiting for a preset duration, re-determining whether the RS information corresponding to the update request information is in a read-write state.
Step S12, the RS information corresponding to the update request information is updated in the shared memory by the target process that receives the update request information.
The RS information corresponding to the update request information is updated in the shared memory by the target process that receives the update request information, and the update request information may be the update request information of the RS information sent by the established control center. An RS update list will be sent to Nginx, where the update request information of the RS information contains the upstream name and the new RS list. And a worker process in the Nginx receives the request and analyzes the content, and updates the RS information on the shared memory.
Because the worker process acquires the RS information from the shared memory, the RS information corresponding to the updating request information in the shared memory is updated, and the RS information among all worker processes can be guaranteed to be shared in real time. After the RS information is updated, when an access request of new RS information of the shared memory comes, the scheduled RS information can be taken out from the shared memory when Nginx schedules the RS, and the shared memory is already provided with a new RS list, so that the dynamic update of the RS is realized.
Step S34, unlock the RS information.
Step S51, receiving the request information of the RS information of the load balancing backend server, and acquiring updated RS information in the shared memory corresponding to the request information through a preset process.
Optionally, before receiving the update request information of the RS information, the method further includes: when a reverse proxy server is started, a shared memory is established; and storing the RS information into the shared memory.

Therefore, the RS information updating method provided by the embodiment of the application can receive the updating request information of the RS information, wherein the RS information is stored in the shared memory; and updating the RS information corresponding to the update request information in the shared memory through the target process receiving the update request information. The RS information can be dynamically updated, the updating cost of the RS information is reduced, and the updating efficiency of the RS information is improved.
