With the continuous development of computer technology, distributed systems are usually used in network applications. Multiple servers are used to provide services. Each server has hundreds of processes. The process configuration of these servers is usually the same. When the process configuration needs to be modified, the process configuration must be modified for all servers.

At present, zookeeper is often used to centrally manage all process configuration information in multiple servers. Zookeeper, as the name suggests, zookeeper, in the field of computer technology, zookeeper is a reliable coordination system for large-scale distributed systems, providing functions such as configuration maintenance, name service, distributed synchronization, group service and so on. The existing zookeeper-based information configuration scheme is: each process in each server must establish a long connection with the zookeeper server, and each process monitors the configuration information of its own process by calling the interface of the zookeeper server, when a certain process When the configuration information needs to be modified, the operator only needs to modify the corresponding configuration information on the zookeeper server. Once the configuration information of the zookeeper server is changed, the corresponding server process updates the configuration of the process according to the modified configuration information on the zookeeper server. information.

Since in practice, there are often hundreds of servers serving together, each server usually runs at least hundreds of processes, for example, if there are 100 servers providing services together, and each server runs 200 processes, each server Each process establishes a long connection with the zookeeper server. A total of 20,000 connections need to be established. This configuration method imposes a large load on the zookeeper server and seriously affects the processing performance of the zookeeper server.

BRIEF DESCRIPTION OF THE DRAWINGS

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

Please refer to FIG. 1 , which is a flowchart of Embodiment 1 of a zookeeper-based information configuration method according to an embodiment of the present invention. The method includes Step 101 and Step 102:

Step 101: Start a process to occupy a lock between processes, and establish a long connection between the process and the zookeeper server, and monitor all configuration information in the local disk through the process, so that the zookeeper server changes when the configuration information changes. Sending an update configuration information notification to the process.

A process is the basis of the operating system structure. It is a program that is being executed. When any process in the server starts running, it needs to read the configuration information first, and then process the program according to the configuration.

In the embodiment of the present invention, a process is started to occupy a lock between processes in order to realize sharing of resources between multiple processes in a server. When a process modifies shared data, other processes cannot operate on shared data at the same time, any one. Processes operate on shared data, and other processes can see it immediately. In order to achieve this, the server system kernel is required to provide locks. The specific implementation of such locks is: file lock (record lock), System V semaphore lock (signal light), mutex lock, condition variables, read-write locks, and so on. File locks and semaphore locks are generally used for synchronization between processes. Mutexes, condition variables, and read-write locks are generally used for synchronization between threads, and are determined according to actual conditions, and are not specifically limited herein.

In this step, a process is started to occupy the lock between the processes, and a long connection between the process and the zookeeper server is established, and all the configuration information on the local disk is monitored by the process. Specifically, there are two implementation manners. Two implementations are explained.

The first implementation manner may include:

Start a process dedicated to monitoring process configuration information to occupy locks between processes;

A long connection between the process dedicated to monitoring process configuration information and the zookeeper server is established, and all configuration information in the local disk is monitored by the process dedicated to monitoring process configuration information.

The server starts a process dedicated to monitoring process configuration information. This process is only used to monitor the configuration information of all processes in the server. The process occupies a lock between processes to achieve synchronization between all processes. The actual function of the lock is that when a process dedicated to monitoring process configuration information writes data to the local disk, other processes cannot perform any operations on the data of the local disk. Similarly, when other processes read data from the local disk. Processes that are dedicated to monitoring process configuration information cannot perform any operations on the local disk. Therefore, by occupying inter-process locks, all processes do not interfere with local disk operations.

The second implementation manner may include:

The process of starting the configuration information to be read occupies a lock between processes;

Starting a thread or a process in the process of the configuration information to be read, establishing a long connection between the thread or the process and the zookeeper server, and monitoring all configurations in the local disk by the thread or the process information.

When a process in the server needs to read the configuration information, the process that uses the configuration information to be read occupies the lock between the processes. The specific function of the lock is the same as the above function, and will not be described here.

The process of the configuration information to be read may start a long connection between a thread and a zookeeper server, and monitor all configuration information in the local disk through the thread; or, the process of the configuration information to be read starts a A long connection between the process and the zookeeper server, and through this process to monitor all configuration information on the local disk.

In order to not affect the main process execution rate of the process, and the system resources are not wasted, the embodiment of the present invention further provides a preferred solution.

As a preferred solution of the embodiment of the present invention, a thread started by the process of the configuration information to be read may be an asynchronous thread.

Because the process maintains a long connection with the zookeeper server, when the operator needs to modify the configuration, only the corresponding configuration information on the zookeeper server needs to be modified. When the configuration information monitored in the zookeeper server changes, it will immediately The process issues an update configuration information notification.

Step 102: The process obtains corresponding configuration information from the zookeeper server and updates it to the local disk according to the received update configuration information notification, so that the process of the configuration information to be read searches for the corresponding one from the local disk. The configuration information, if the corresponding configuration information is found, the process of the configuration information to be read reads the configuration information corresponding to the configuration from the local disk; if the corresponding configuration information is not found, the process of the configuration information to be read Establish a short connection with the zookeeper server, and obtain the corresponding configuration information from the zookeeper server and store it on the local disk.

According to the update configuration information, the configuration information is obtained from the zookeeper server and updated to the local disk, so that the latest configuration information is stored in the local disk, so that any process can be The configuration information corresponding to the local disk read is the latest configuration information, ensuring real-time update of the configuration information to ensure that each process in the server is correctly executed.

When a process needs to be run on the server, you must first read its own configuration information and only need to find its own configuration information from the local disk.

When the corresponding configuration information is not found, the configuration information of the current process to be read configuration information has not been monitored. Therefore, the process of the current configuration information to be read needs to establish a short connection with the zookeeper server. The zookeeper server obtains its corresponding configuration information and stores it on the local disk.

The so-called short connection is two connection methods opposite to the long connection. The short connection operation steps are: establishing a connection---data transmission---closing the connection. The short connection method is to disconnect immediately after establishing the connection transmission data. The long connection is performed by: establishing a connection---data transfer---(always staying connected)---data transfer----closing the connection. The long connection method does not disconnect after establishing the connection transmission data, and this communication connection relationship always exists. In contrast, short connection methods can save server system resources.

The process of establishing a long connection with the zookeeper server scans the local disk. When it finds the configuration information of the new process in the local disk (that is, when there is configuration information that has not been monitored in the local disk), the configuration information is added to the monitoring content. Ensure that the configuration information of all processes on the local disk can be monitored in time to update the configuration information of all processes in real time.

By starting a process that occupies a lock between processes, other processes in the process of modifying the shared data cannot perform any operation on the shared data, and the process can immediately know the operation of the shared data, and establish the A long connection between the process and the zookeeper server, which scans the local disk to monitor all configuration information on the local disk.

Obtain the corresponding configuration information from the zookeeper server according to the received notification, and update to the local disk. When any process needs to obtain the configuration information, only the local disk needs to be obtained to obtain the corresponding configuration information, and no need to cooperate with the zookeeper. A long connection is established between the servers; if there is no corresponding configuration information in the local disk, the related configuration information of the process has not been monitored. In this case, the process only needs to establish a short connection with the zookeeper server. The zookeeper server obtains its own configuration information and stores it on the local disk so that the configuration information is also monitored.

It can be seen that, according to the method provided by the present invention, each server does not need to establish a long connection between each process and the zookeeper server, but uses the lock between the process and the local disk to establish only one process and the zookeeper server. Long connection between the two, and using the short connection method at the beginning, It can ensure that the configuration information of all processes is monitored and the load of the zookeeper server is reduced.

The configuration information of the above-mentioned zookeeper-based information configuration method is stored in the local disk. The process of viewing the local disk and obtaining the corresponding configuration information is inferior, resulting in low process performance of the entire server. The invention also provides a preferred solution.

Referring to FIG. 2, a flowchart of Embodiment 2 of a zookeeper-based information configuration method according to an embodiment of the present invention is shown. The method includes Step 201 and Step 202:

In step 201, a process is started to occupy the lock between the processes, and a long connection between the process and the zookeeper server is established, and all configuration information in the shared memory is monitored by the process, so that the zookeeper server changes when the configuration information changes. Sending an update configuration information notification to the process;

Step 202: The process obtains corresponding configuration information from the zookeeper server and updates to the local disk and the shared memory according to the received update configuration information notification, so that the process of the configuration information to be read is from the shared memory and the local The process of searching for the corresponding configuration information on the disk, if the corresponding configuration information is found, the process of the configuration information to be read reads the configuration information corresponding to the configuration from the shared memory; if the corresponding configuration information is not found, the The process of reading the configuration information establishes a short connection with the zookeeper server, and obtains the corresponding configuration information from the zookeeper server and stores it in the shared memory and the local disk.

If any of the processes in the server needs to be run, you need to obtain the configuration information. First, check whether the configuration information is saved in the shared memory. If not, check whether the corresponding configuration information is saved in the local disk. The configuration information of the process is saved on the local disk while being saved in the shared memory. Therefore, the configuration information saved in the local disk and the shared memory is the same. Just look at any of them, but consider that the data in the shared memory may be lost for some reason, and the data on the local disk is generally persistent and not easily lost. Therefore, the way to store the configuration information on the local disk ensures the reliability of the configuration information. The way to store the configuration information in the shared memory ensures the operating rate of the system and improves system performance. Therefore, both shared memory and local disks are viewed to avoid information viewing omissions.

Different from the first embodiment, in the embodiment, after the configuration information is stored in the local disk, the configuration information is further stored in the shared memory, and the process reads the data from the shared memory at a slower speed. It is much faster than reading data from a local disk, so the rate of process configuration information is increased by reading the corresponding configuration information from the shared memory.

The following is a description of the above-mentioned example of the information configuration method of the zookeeper based on the web server. For details, please refer to FIG. 3, which shows an information configuration framework of the zookeeper based on the embodiment of the present invention.

A web server usually runs 128 fast page mode (English short page mode, abbreviated as fpm) process to provide services. According to step 201 and step 202 above, a process is started to occupy the lock between processes, and a process is established between the process and the zookeeper server. Long connection, then the process according to the update configuration information notification to obtain configuration information from the zookeeper server, and update to the local disk and shared memory, when any process in the web server needs to obtain configuration information, directly from the share The corresponding configuration information is found in the memory. If the configuration information is found, the configuration information is directly obtained. If the short connection is established with the zookeeper server, the corresponding configuration information is obtained and stored in the local disk and the shared memory. It can be seen that the entire web server only needs to establish a long connection with the zookeeper server and establish a short connection when the configuration information is first acquired, so that the configuration information of all processes can be monitored and updated in time.

Please refer to FIG. 4, which shows a prior art zookeeper-based information configuration framework. Each process in the web server must establish a long connection with the zookeeper server, as compared to the embodiment of the present invention. The zookeeper-based information configuration method can greatly reduce the long connection with the zookeeper, thereby reducing the load of the zookeeper server while ensuring that all process configuration information in the server is monitored.

By starting a process to occupy the lock between processes and establishing a long connection between the process and the zookeeper server, it is ensured that the configuration information used by the process is updated and saved in time, reducing the load on the zookeeper server. In addition, the configuration information is stored in the shared memory, so that the process of the configuration information to be read obtains the configuration information corresponding to the configuration through the shared memory, thereby improving the rate of obtaining the configuration information, thereby improving the processing performance of the server.

Preferably, the second monitoring sub-unit is configured to start an asynchronous thread in the process of the configuration information to be read, and establish a long connection between the asynchronous process and the zookeeper server, by using the asynchronous thread Monitor configuration information of all processes in the interprocess communication.

As can be seen from the above embodiments, the beneficial effects of the present invention are:

Obtain corresponding configuration information from the zookeeper server according to the received notification, and update On the local disk, if you need to obtain the configuration information, you need to go to the local disk to obtain the corresponding configuration information. You do not need to establish a long connection with the zookeeper server. If there is no corresponding configuration information on the local disk, The configuration information about the process has not been monitored. In this case, the process only needs to establish a short connection with the zookeeper server, obtain the configuration information from the zookeeper server and store it on the local disk, so that the configuration information is also Get monitored.

It can be seen that, according to the device provided by the present invention, each server does not need to establish a long connection between each process and the zookeeper server, but uses the lock between the process and the local disk to establish only one process and the zookeeper server.
