第1篇一、基础知识1. 什么是服务注册中心?它在微服务架构中扮演什么角色?服务注册中心是一种分布式服务发现和配置管理的解决方案。
在微服务架构中,服务注册中心负责管理服务的注册和发现,使得服务消费者能够动态地发现和访问服务提供者。
服务注册中心的主要作用包括:(1)服务注册:服务提供者在启动时将自己的信息注册到注册中心,包括服务名称、IP地址、端口等。
(2)服务发现:服务消费者通过注册中心获取服务提供者的信息,包括服务名称、IP地址、端口等,实现服务的动态发现。
(3)服务配置:服务注册中心可以存储服务的配置信息,如数据库连接、缓存配置等,服务消费者可以根据需要获取相应的配置信息。
2. 服务注册中心有哪些常见的实现方式?服务注册中心常见的实现方式包括:(1)基于数据库:通过数据库存储服务信息,如Consul、Etcd等。
(2)基于内存:通过内存存储服务信息,如Eureka、Zookeeper等。
(3)基于文件系统:通过文件系统存储服务信息,如Nacos等。
3. 服务注册中心的主要功能有哪些?服务注册中心的主要功能包括:(1)服务注册:服务提供者将自身信息注册到注册中心。
(2)服务发现:服务消费者从注册中心获取服务提供者的信息。
(3)服务健康检查:监控服务提供者的状态,如心跳检测、服务降级等。
(4)服务配置:存储和读取服务的配置信息。
(5)服务监控:收集和展示服务的性能数据。
二、Eureka1. 什么是Eureka?它与其他服务注册中心有何区别?Eureka是Netflix开源的、基于Java实现的服务注册中心,它与其他服务注册中心的区别如下:(1)实现语言:Eureka基于Java实现,其他服务注册中心可能基于其他语言实现。
(2)功能:Eureka提供的服务注册、服务发现、服务配置等功能与其他服务注册中心类似。
(3)社区活跃度:Eureka社区活跃,拥有丰富的文档和社区支持。
2. Eureka的主要组件有哪些?Eureka的主要组件包括:(1)Eureka Server:服务注册中心,负责服务注册、服务发现、服务配置等。

它包括如下几个显著特点:完整的ACID支持高可用性轻易扩展到上亿级别的节点和关系通过遍历工具高速检索数据适当的ACID操作是保证数据一致性的基础。
Neo4j确保了在一个事务里面的多个操作同时发生,保证数据一致性。
不管是采用嵌入模式还是多服务器集群部署,都支持这一特性。

可靠的图型存储可以非常轻松的集成到任何一个应用中。
随着我们开发的应用在运营中不断发展,性能问题肯定会逐步凸显出来,而Neo4j不管应用如何变化,他只会受到计算机硬件性能的影响,不受业务本身的约束。
部署一个neo4j服务器便可以承载上亿级的节点和关系。

Spring的数据绑定是高度灵活的:例如,将验证错误类型不作为应用系统错误,可以通过评估的不匹配。
因此,你不必重复你的业务对象的属性,简单的无类型的字符串,在表单对象仅仅是为了处理无效的意见,或正确转换的字符串。
相反,它往往是最好直接绑定到业务对象。

HA 3.0 说明——by mzhaoHA概论 (2)HA3.0结构 (4)安装 (6)配置 (8)主机配置 (8)Heartbeat配置 (8)pacemaker配置 (9)Pacemaker详解 (12)参考资料 (13)HA概论高可用集群,英文原文为High Availability Cluster,简称HA Cluster,是指以减少服务中断(如因服务器宕机等引起的服务中断)时间为目的的服务器集群技术。
简单的说,集群(cluster)就是一组计算机,它们作为一个整体向用户提供一组网络资源。
这些单个的计算机系统就是集群的节点(node)。
高可用集群的出现是为了使集群的整体服务尽可能可用,从而减少由计算机硬件和软件易错性所带来的损失。
它通过保护用户的业务程序对外不间断提供的服务,把因软件/硬件/人为造成的故障对业务的影响降低到最小程度。
如果某个节点失效,它的备援节点将在几秒钟的时间内接管它的职责。
因此,对于用户而言,集群永远不会停机。
高可用集群软件的主要作用就是实现故障检查和业务切换的自动化。
只有两个节点的高可用集群又称为双机热备,即使用两台服务器互相备份。
当一台服务器出现故障时,可由另一台服务器承担服务任务,从而在不需要人工干预的情况下,自动保证系统能持续对外提供服务。
双机热备只是高可用集群的一种,高可用集群系统更可以支持两个以上的节点,提供比双机热备更多、更高级的功能,更能满足用户不断出现的需求变化。
从这个定义可以看出,集群必须检测节点和服务何时失效,何时恢复为可用。
这个任务通常由一组被称为“心跳”的代码完成。
在Linux-HA里这个功能由一个叫做heartbeat的程序完成。
Heartbeat是Linux-HA工程的一个组件,自1999年开始到现在,发布了众多版本,是目前开源Linux-HA项目最成功的一个例子,在行业内得到了广泛的应用。
Heartbeat通过插件技术实现了集群间的串口、多播、广播和组播通信,在配置的时候可以根据通信媒介选择采用的通信协议,heartbeat启动的时候检查这些媒介是否存在,如果存在则加载相应的通信模块。

Dynamic Service Discovery and Invocation in OHPD. E. Millard, S. Reich, H. C. DavisMultimedia Research GroupThe University of Southampton SO17 1BJ, Southampton UK {dem97r, sr}@ecs.soton.ac.uk, hcd@multicosm.com
AbstractThe Open Hypermedia Protocol (OHP) was originally envisaged as a simple but comprehensive protocol to deal with hypermedia navigation. However it contained aspects of other functionality, most noticeably hypermedia collaboration and dynamic service invocation. As the protocol has evolved it has become apparent that to properly deal with these areas OHP would need to be much larger and more complex then was appropriate. This paper describes the ideas behind dynamic services and presents an optional extension to OHP that is domain independant. We believe that by splitting the functionality of OHP into a suite of packages or modules we may better divide and conquer the problems we have encountered.
1. Introduction
The Open Hypermedia Systems Working Group (OHSWG, http://www.ohswg.org/) has promoted research towards interoperability amongst hypermedia systems and integration with the World-Wide Web. To this end it has been actively investigating the possibility of a generalised protocol for hypermedia navigation that would enable interoperability between hypermedia systems. The Open Hypermedia Protocol (OHP) [Davis et al. 96] was originally designed to encompass the area of hypermedia navigation as well as several others that were deemed too important to ignore, these included collaboration and services.
As work on the protocol has progressed it has become apparent that these sub-areas are more complex then one might expect, in addition other domains have been identified e.g. Spatial and Taxonomic hypermedia [Nürnberg & Leggett 97]. To include this complexity in a general OHP protocol would be a strong disincentive for using it, and yet the subjects are to important to exclude.
A possible approach is to divide OHP into a suite of similar, related protocols, all using the same meta-information and delivery mechanism. Thus OHP-Navigational (OHP-Nav), OHP-Taxanomic (OHP-Tax) and OHP-Space were born (although OHP-Nav is currently the only mature definition, containing most of the functionality in the original OHP definition). Recently it has been decided to remove dynamic services from the Navigational protocol and into a package of their own that can be applied to any domain (The Service Package).
2. Why Services?
Services first appeared in the original OHP definition [Davis et al. 96], although they were never completely defined. A Service is a black box of functionality, known only by name to a client, that can be invoked and its results understood, even though its workings are completely opaque. In this way a generalised client gains access to complex functionality that would otherwise be unavailable.
There are therefore three ways to examine the data in an OHP system. Firstly by using the operations defined in OHP-Nav, i.e. Create, Delete etc. Secondly by utilizing a query facility, i.e. get all Nodes where Attribute 'Author' equals 'D.Millard'. Thirdly by using the Service Package to dynamically discover what services a server has to offer and then dynamically invoking them. This third method has the advantage that it allows us to use functionality stored on the server as well as data (for example, an effective search algorithm that depends on system knowledge to operate).
3. What About Standard Services?
In the older definitions of OHP-Nav [Davis et al. 97] there were four standard services that had defined semantics:1.Follow Link - returns all the other endpoints (not the original input endpoint) which are associated with the input endpoint via any link structure. It only returns those that it believes the user will be interested in given the current context. 2.Show Endpoints - returns all the endpoints within this node that the linkserver believes the user will be interested in given the current context 3.Show Links - returns all the links that connect to this node that the linkserver believes the user will be interested in given the current context 4.Get Relevant Nodes - returns a list of nodes managed by the linkserver that may act as starting points for the user given the current context
Since the current version of OHP-Nav (used for the demonstation at Hypertext '99) does not contain services at all, these standard services have become operations. This results in a few advantageous side effects. It means that any server that is OHP-Nav compliant must understand and implement them, this is different to standard services which a server may or may not offer. Also it means that the messages that deal with this functionality can be much more specifically tailored for the task (as opposed to being generalised to cope with any service).
