本发明涉及一种服务器连接方法及服务器系统，具体涉及一种基于zookeeper的服务器连接方法及服务器系统。The invention relates to a server connection method and server system, in particular to a zookeeper-based server connection method and server system.
背景技术Background technique
目前，在企业的一些内部系统中，Web服务器到后台存储服务器的访问通常需要经过LVS，LVS是一个开源的软件，其全称为:Linux Virtual Server，可以实现LINUX平台下的简单负载均衡。比如，在一个云存储系统中，由Web服务器接收用户上传的文件，然后，通过LVS选择存储节点，把数据保存在存储节点。如图1所示，Web服务器如果想要访问后台数据库服务器集群中的一个数据库进行数据的存取，要通过LVS来和该数据库打交道，通常的流程是Web服务器首先连接LVS，然后，LVS根据算法取一个后台数据库，接着，Web服务器根据LVS运行的模式，通过直接或者间接的方式与数据库打交道。例如，LVS在采用IP Tunneling(隧道技术)模式的情况下，Web服务器需要与后台数据库2建立联系，则Web服务器首先连接LVS，LVS根据特定算法，把Web服务器的服务请求发给数据库2进行处理，数据库2将处理结果返回给LVS，LVS再把该结果返回给Web服务器。At present, in some internal systems of enterprises, the access from the Web server to the background storage server usually needs to go through LVS. LVS is an open source software, and its full name is: Linux Virtual Server, which can realize simple load balancing under the LINUX platform. For example, in a cloud storage system, the web server receives the files uploaded by the user, and then selects the storage node through LVS, and saves the data in the storage node. As shown in Figure 1, if the web server wants to access a database in the background database server cluster for data access, it needs to deal with the database through LVS. The usual process is that the web server first connects to LVS, and then, LVS Take a background database, and then, the Web server deals with the database directly or indirectly according to the operating mode of LVS. For example, when LVS adopts IP Tunneling (tunneling technology) mode, the Web server needs to establish a connection with the background database 2, then the Web server first connects to LVS, and LVS sends the service request of the Web server to the database 2 for processing according to a specific algorithm , database 2 returns the processing result to LVS, and LVS returns the result to the Web server.
在现有技术的处理模式中，由于处理请求的过程中多了一次LVS网络连接，这势必会增加Web服务器与数据库之间处理应答的响应时间，如果在后台的数据库或者其他服务器需要很长的处理时间时，LVS会把与后台数据库的连接断掉，但是又不通知前面的Web服务器，从而导致Web服务器的处理长时间等待。In the processing mode of the prior art, since there is one more LVS network connection in the process of processing the request, this will inevitably increase the response time for processing responses between the Web server and the database. If the database or other servers in the background require a long When processing time, LVS will disconnect the connection with the background database, but does not notify the front Web server, which causes the Web server to wait for a long time.

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
如图2所示，当Web服务器需要与后端服务器，比如某数据库集群中的第2个数据库进行数据通信时，首先要检查本地是否缓存有后端服务器集群列表，若未发现本地缓存的后端服务器集群列表，则通过配置服务器从后端服务器集群中获取后端服务器集群列表，并将该列表缓存在本地；当Web服务器从本地缓存获得后端服务器集群列表时，根据一定策略选择后端服务器的数据库2，Web服务器直接连接选中的数据库2，向其发送数据处理请求，并等待处理结束。基于该原理所用的配置服务器例如为zookeeper配置服务器，Zookeeper是Google的Chubby一个开源的实现，是高有效和可靠的协同工作系统，在一个分布式的环境中，需要一个Master实例或存储一些配置信息，确保文件写入的一致性等。Zookeeper是一个分布式的，开放源码的分布式应用程序协调服务，包含一个简单的原语集，是Hadoop和Hbase的重要组件。分布式应用可以使用它来实现诸如：统一命名服务、配置管理、分布式锁服务、集群管理等功能。在Zookeeper中的每个节点叫做znode，并且其有一个唯一的路径标识，znode是一个跟Unix文件系统路径相似的节点，可以往这个节点存储或获取数据。如果在创建znode时Flag设置为EPHEMERAL，那么当创建的这个znode的节点和Zookeeper失去连接后，这个znode将不再存在在Zookeeper里。Zookeeper使用Watcher察觉事件信息,当客户端接收到事件信息,比如连接超时，节点数据改变，子节点改变，可以调用相应的行为来处理数据。ZooKeeper的基本运转流程为：①选举Leader；②同步数据；③选举Leader过程中算法有很多，但要达到的选举标准是一致的；④Leader要具有最高的zxid；⑤集群中大多数的机器得到响应并follow选出的Leader。As shown in Figure 2, when the web server needs to communicate with the back-end server, such as the second database in a database cluster, it must first check whether there is a list of back-end server clusters in the local cache. end server cluster list, the configuration server obtains the backend server cluster list from the backend server cluster, and caches the list locally; when the web server obtains the backend server cluster list from the local cache, selects the backend server according to a certain The database 2 of the server, the Web server directly connects to the selected database 2, sends a data processing request to it, and waits for the processing to end. The configuration server used based on this principle is, for example, the zookeeper configuration server. Zookeeper is an open source implementation of Google's Chubby. It is a highly efficient and reliable collaborative work system. In a distributed environment, a Master instance or storage of some configuration information is required. , to ensure the consistency of file writing, etc. Zookeeper is a distributed, open source distributed application coordination service that contains a simple set of primitives and is an important component of Hadoop and Hbase. Distributed applications can use it to implement functions such as: unified naming service, configuration management, distributed lock service, cluster management, etc. Each node in Zookeeper is called a znode, and it has a unique path identifier. A znode is a node similar to the Unix file system path, and data can be stored or retrieved from this node. If the Flag is set to EPHEMERAL when creating a znode, then when the node of the created znode loses connection with Zookeeper, the znode will no longer exist in Zookeeper. Zookeeper uses Watcher to detect event information. When the client receives event information, such as connection timeout, node data changes, and child nodes change, the corresponding behavior can be called to process the data. The basic operation process of ZooKeeper is: ①Elect Leader; ②Synchronize data; ③There are many algorithms in the process of electing Leader, but the election standards to be achieved are consistent; ④Leader must have the highest zxid; ⑤Most machines in the cluster get a response And follow the elected Leader.
适用于本发明原理的策略选择可以采用负载均衡算法，负载均衡算法中常用到的有随机选择算法，随机选择算法是用负载均衡方法随机的把负载分配到各个可用的服务器上，通过随机数生成算法选取一个服务器，然后把连接发送给它；还常用到的可以是轮询算法，轮询算法按顺序把每个新的连接请求分配给下一个服务器，最终把所有请求平分给所有的服务器，轮询算法在大多数情况下都工作的不错，但是如果负载均衡的设备在处理速度、连接速度和内存等方面不是完全均等，那么效果会更好，当然，进一步的，可以使用涉及权重比例分配接受连接数量的加权轮询算法，也可以使用对权重值持续监控并不断更新的动态轮询算法；还常用到的是最少连接算法，系统把新连接分配给当前连接数目最少的服务器。该算法在各个服务器运算能力基本相似的环境中非常有效。例如，目前系统有个20个搜索引擎服务器、1个总服务器、1个备用总服务器和一个web服务器，其中，每个搜索引擎服务器负责总索引中的一部分搜索任务，总服务器负责向这20个搜索引擎服务器发出搜索请求并合并结果集，备用总服务器负责当总服务器宕机时自动替换总服务器。当web服务器的CGI(Common Gateway Interface)向总服务器发出搜索请求时，假设搜索引擎服务器中的15个服务器现在提供搜索服务，5个搜索引擎服务器正在生成索引，使用Zookeeper可以保证总服务器自动感知有多少提供搜索引擎的服务器并向这些服务器发出搜索请求，这20个搜索引擎服务器经常要让正在提供搜索服务的服务器停止提供服务开始生成索引,或生成索引的服务器已经把索引生成完成可以搜索提供服务了。The strategy selection applicable to the principle of the present invention can adopt load balancing algorithm, and random selection algorithm is commonly used in load balancing algorithm, and random selection algorithm is to use load balancing method to distribute the load to each available server at random, through random number generation The algorithm selects a server, and then sends the connection to it; the polling algorithm is also commonly used, and the polling algorithm assigns each new connection request to the next server in order, and finally distributes all requests equally to all servers. The round robin algorithm works well in most cases, but if the load balancing devices are not completely equal in terms of processing speed, connection speed and memory, the effect will be better. Of course, further, you can use weight ratio distribution The weighted polling algorithm that accepts the number of connections can also use the dynamic polling algorithm that continuously monitors and updates the weight value; the least connection algorithm is also commonly used, and the system assigns new connections to the server with the least number of current connections. This algorithm is very effective in an environment where the computing power of each server is basically similar. For example, the system currently has 20 search engine servers, 1 main server, 1 backup main server and a web server, wherein each search engine server is responsible for a part of the search tasks in the general index, and the main server is responsible for submitting the search tasks to the 20 The search engine server sends out the search request and merges the result sets, and the standby total server is responsible for automatically replacing the total server when the total server is down. When the CGI (Common Gateway Interface) of the web server sends a search request to the general server, assuming that 15 servers in the search engine server are now providing search services, and 5 search engine servers are generating indexes, the use of Zookeeper can ensure that the total server automatically perceives that there is a search request. How many servers that provide search engines and send search requests to these servers, these 20 search engine servers often have to make the servers that are providing search services stop providing services and start generating indexes, or the servers that generate indexes have completed the index generation and can search and provide services up.
图3所示为本发明的一个实施例，其原理与图2所示一致，具体的，一种服务器连接方法，用于把WEB服务器连接到后端服务器，该方法包括：Figure 3 shows an embodiment of the present invention, and its principle is consistent with that shown in Figure 2. Specifically, a server connection method is used to connect a WEB server to a backend server, and the method includes:
步骤S110，Web服务器检查本地是否缓存有后端服务器集群列表，若没有缓存，则执行步骤S120，若有缓存，则执行步骤S130；Step S110, the web server checks whether there is a list of backend server clusters in the local cache, if there is no cache, then execute step S120, if there is cache, then execute step S130;
步骤S120，Web服务器通过配置服务器从后端服务器集群中获取后端服务器集群列表并进行本地缓存，该配置服务器是基于zookeeper的配置服务器，通过调取后端服务器集群的应用程序编程接口(API，Application Programming Interface)获得后端服务器集群列表，配置服务器按照设定的时间间隔读取应用程序编程接口(API)来判断后端服务器集群列表是否发生变化，若发生变化则根据变化情况更新其获得的后端服务器集群列表，并将更新后的后端服务器集群列表缓存在本地，当然，配置服务器也可以通过管理员向其手动输入或更新后端服务器集群列表；Step S120, the web server obtains the list of back-end server clusters from the back-end server cluster through the configuration server and performs local caching. The configuration server is a configuration server based on zookeeper, and the application programming interface (API, Application Programming Interface) to obtain the list of back-end server clusters, the configuration server reads the application programming interface (API) according to the set time interval to determine whether the list of back-end server clusters has changed, and if there is a change, it will update the obtained information according to the change Back-end server cluster list, and cache the updated back-end server cluster list locally. Of course, the configuration server can also manually input or update the back-end server cluster list through the administrator;
步骤S130，Web服务器获取缓存的后端服务器集群列表并从所述缓存的后端服务器集群列表中选择指定后端服务器，这种选择方法可以采用随机选择，也可以采用负载均衡算法进行选择，负载均衡算法可以为，Web服务器按下面公式计算后端服务器集群列表中的各个后端服务器的负载值：Step S130, the web server obtains the cached list of backend server clusters and selects a designated backend server from the cached list of backend server clusters. The selection method can be random selection or a load balancing algorithm. The balancing algorithm can be that the web server calculates the load value of each backend server in the backend server cluster list according to the following formula:
后端服务器的负载值＝k1*cpu使用量+k2*处理器性能+k3*内存余量+k4*带宽资源；The load value of the backend server = k1*cpu usage+k2*processor performance+k3*memory margin+k4*bandwidth resources;
其中，所述k1为cpu使用量所对应的权值，所述k2为处理器性能所对应的权值，所述k3为内存余量所对应的权值，所述k4为带宽资源所对应的权值，这些权值都是可以根据需要人为设定的；Web服务器选择负载值最小的后端服务器作为指定后端服务器；比如后台服务器集群列表中有3个数据库，在各参数使用归一化处理后数据库1的负载值＝0.5+0.8+0.6+0.7＝2.6；数据库2的负载值＝0.6+0.8+0.7+0.7＝2.8；数据库3的负载值＝0.8+0.7+0.3+0.7＝2.5，则Web服务器选择负载值最小的数据库3作为指定后端服务器；Wherein, the k1 is the weight corresponding to the cpu usage, the k2 is the weight corresponding to the processor performance, the k3 is the weight corresponding to the memory margin, and the k4 is the bandwidth resource corresponding Weights, these weights can be set manually according to needs; the web server selects the back-end server with the smallest load value as the designated back-end server; for example, there are 3 databases in the back-end server cluster list, and normalization is used for each parameter After processing, the load value of database 1=0.5+0.8+0.6+0.7=2.6; the load value of database 2=0.6+0.8+0.7+0.7=2.8; the load value of database 3=0.8+0.7+0.3+0.7=2.5, Then the web server selects the database 3 with the smallest load value as the designated backend server;
步骤S140，Web服务器直接连接指定后端服务器；Step S140, the web server directly connects to the specified backend server;
步骤S150，Web服务器发送数据处理请求至该指定后端服务器，并等待指定后端服务器返回的处理结果。In step S150, the web server sends a data processing request to the designated backend server, and waits for a processing result returned by the designated backend server.
通过本实施例可以发现，Web服务器与后端服务器需要进行数据处理交换时，在没有后端服务器集群列表的情况下，可通过zookeeper配置服务器获取后端服务器集群列表，从而使Web服务器可以直接与后端服务器连接进行请求处理，网络处理环节少了一个，不需要经过中间环节Web服务器即可与后端服务器直接通讯，明显提高了处理效率。另外，在后端服务器处理没有结束的情况下，Web服务器可以等待后端服务器的处理，而不会出现连接被断掉却没有感知的情况。使用zookeeper配置服务器另一个好处是，当后端服务器集群列表发生变动时，zookeeper配置服务器能够及时获得更新内容并通知Web服务器进行本地缓存的更新。Through this embodiment, it can be found that when the Web server and the back-end server need to perform data processing and exchange, in the absence of a list of back-end server clusters, the list of back-end server clusters can be obtained through the zookeeper configuration server, so that the Web server can directly communicate with The back-end server is connected to request processing, and there is one less network processing link, and the web server can directly communicate with the back-end server without going through the intermediate link, which significantly improves the processing efficiency. In addition, when the processing of the back-end server is not finished, the Web server can wait for the processing of the back-end server, and there will be no situation that the connection is disconnected without being aware of it. Another advantage of using the zookeeper configuration server is that when the list of backend server clusters changes, the zookeeper configuration server can obtain updated content in time and notify the web server to update the local cache.
图4所示为本发明的另一个实施例，是基于图2原理的一种服务器系统，该系统包括配置服务器310和Web服务器320，其中，配置服务器310用于获取后端服务器集群列表；Web服务器320用于检查本地是否缓存有后端服务器集群列表；若没有缓存后端服务器集群列表，则从配置服务器310获取后端服务器集群列表并进行本地缓存；若缓存有后端服务器集群列表，则获取缓存的后端服务器集群列表并从中选择指定后端服务器，直接连接该指定后端服务器进行数据通信。配置服务器310通过调取后端服务器集群的应用程序编程接口(API)获得后端服务器集群列表，按照设定的时间间隔读取应用程序编程接口(API)来判断后端服务器集群列表是否发生变化，若发生变化则根据变化情况更新其获得的后端服务器集群列表。Fig. 4 shows another embodiment of the present invention, is a kind of server system based on Fig. 2 principle, and this system comprises configuration server 310 and Web server 320, and wherein, configuration server 310 is used for obtaining back-end server cluster list; Web The server 320 is used to check whether the local cache has a back-end server cluster list; if there is no cache back-end server cluster list, then obtain the back-end server cluster list from the configuration server 310 and perform local caching; if there is a back-end server cluster list in the cache, then Obtain the cached backend server cluster list and select a specified backend server from it, and directly connect to the specified backend server for data communication. The configuration server 310 obtains the back-end server cluster list by calling the application programming interface (API) of the back-end server cluster, and reads the application programming interface (API) according to the set time interval to determine whether the back-end server cluster list changes , if there is a change, update the obtained list of backend server clusters according to the change.
进一步的，Web服务器包括列表获取模块321、列表缓存模块322、服务器选取模块323、服务器连接模块324和数据处理模块325，其中，列表获取模块321用于检查Web服务器320本地是否缓存有后端服务器集群列表，若没有缓存后端服务器集群列表，则通过配置服务器310获取后端服务器集群列表；列表缓存模块322用于将列表获取模块321所获取的后端服务器集群列表进行本地缓存；服务器选取模块323用于从列表缓存模块322所缓存的后端服务器集群列表中选择指定后端服务器；服务器连接模块324用于连接指定后端服务器；数据处理模块325用于发送数据处理请求至指定后端服务器，并等待指定后端服务器处理结束，将处理结果返回至数据处理模块。Further, the Web server includes a list acquisition module 321, a list caching module 322, a server selection module 323, a server connection module 324 and a data processing module 325, wherein the list acquisition module 321 is used to check whether the Web server 320 locally caches a backend server Cluster list, if there is no cached back-end server cluster list, then obtain the back-end server cluster list by configuration server 310; 323 is used to select a designated back-end server from the list of back-end server clusters cached by the list cache module 322; the server connection module 324 is used to connect to the designated back-end server; the data processing module 325 is used to send a data processing request to the designated back-end server , and wait for the specified backend server to finish processing, and return the processing result to the data processing module.

本领域那些技术人员可以理解，可以对实施例中的设备中的模块进行自适应性地改变并且把它们设置在与该实施例不同的一个或多个设备中。可以把实施例中的模块或单元或组件组合成一个模块或单元或组件，以及此外可以把它们分成多个子模块或子单元或子组件。除了这样的特征和/或过程或者单元中的至少一些是相互排斥之外，可以采用任何组合对本说明书(包括伴随的权利要求、摘要和附图)中公开的所有特征以及如此公开的任何方法或者设备的所有过程或单元进行组合。除非另外明确陈述，本说明书(包括伴随的权利要求、摘要和附图)中公开的每个特征可以由提供相同、等同或相似目的的替代特征来代替。Those skilled in the art can understand that the modules in the device in the embodiment can be adaptively changed and arranged in one or more devices different from the embodiment. Modules or units or components in the embodiments may be combined into one module or unit or component, and furthermore may be divided into a plurality of sub-modules or sub-units or sub-assemblies. All features disclosed in this specification (including accompanying claims, abstract and drawings) and any method or method so disclosed may be used in any combination, except that at least some of such features and/or processes or units are mutually exclusive. All processes or units of equipment are combined. Each feature disclosed in this specification (including accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise.
应该注意的是上述实施例对本发明进行说明而不是对本发明进行限制，并且本领域技术人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。本发明可以借助于包括有若干不同元件的硬件以及借助于适当编程的计算机来实现。在列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The invention can be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In a unit claim enumerating several means, several of these means can be embodied by one and the same item of hardware. The use of the words first, second, and third, etc. does not indicate any order. These words can be interpreted as names.
