一、DNS服务原理
DNS服务原理
当前TCP/IP网络中的设备之间进行通信,是利用和依赖于IP地址实现的。而人们在使用网络资源的时,那种由文字组成的资源名称,更容易记忆和使用,但是计算机不理解这种名称。DNS( Domain Name System)名字解析服务,能够将人们使用的名称翻译成(解析)成计算机能够理解的IP地址,从而解决了此问题。
DNS:Domain Name System 域名系统,应用层协议,是互联网的一项服务。它作为将域名和IP地址相互映射的一个分布式数据库,包含各种资源记录。从域名到IP地址的解析是由分布在因特网上的许多域名服务器程序共同完成的,因为因特网规模很大,所以整个因特网只使用一个域名服务器是不可行的,早在1983年因特网开始采用层次树状结构的命名方法。
一个DNS服务器所负责管辖(或有权限)的范围叫做区(zone),需要根据具体情况来划分管辖范围的区。在一个区中的所有节点必须是能够连通的,每一个区设置相应的权限域名服务器,用来保存该区中的所有主机到域名IP地址的映射。DNS服务器的管辖范围不都是以“域”为单位,有时是以“区”为单位,区 <= 域。
上图中假定abc公司有下属部门x和y,部门x下面有分三个分布们u,v,w,而y下面还有下属部门t。图a表示abc公司只设一个区abc.com。这时区abc.com和域abc.com指的是同一件事。但图b表示abc公司划分为两个区:abc.com和y.abc.com。这两个区都隶属于域abc.com,都各设置了相应的权限域名服务器。不难看出,区是域的子集。
区域解析库:由众多RR组成:
- 资源记录:Resource Record, RR,定义的格式:
name [TTL] IN rr_type value
- 记录类型:A, AAAA, PTR, SOA, NS, CNAME, MX,TXT
- SOA:Start Of Authority,起始授权记录;一个区域解析库有且仅能有一个SOA记录,必须位于解析库的第一条记录
- A:internet Address,作用,FQDN --> IP
- AAAA:FQDN --> IPv6
- PTR:PoinTeR,IP --> FQDN
- NS:Name Server,专用于标明当前区域的DNS服务器
- CNAME : Canonical Name,别名记录
- MX:Mail eXchanger,邮件交换器
- TXT:对域名进行标识和说明的一种方式,一般做验证记录时会使用此项,如:SPF(反垃圾邮件)记录,https验证等
DNS 查询的过程如下图:
- 在浏览器中输入www.qq.com域名,操作系统会先检查自己本地的hosts文件是否有这个网址映射关系,如果有,就使用这个IP地址映射,完成域名解析。
- 如果hosts里没有这个域名的映射,则查找本地DNS解析器缓存,是否有这个网址映射关系,如果有,直接返回,完成域名解析。
- 如果hosts与本地DNS解析器缓存都没有相应的网址映射关系,首先会找TCP/ip参数中设置的首选DNS服务器,在此我们叫它本地DNS服务器,此服务器收到查询时,如果要查询的域名,包含在本地配置区域资源中,则返回解析结果给客户机,完成域名解析,此解析具有权威性。
- 如果要查询的域名,不由本地DNS服务器区域解析,但该服务器已缓存了此网址映射关系,则调用这个IP地址映射,完成域名解析,此解析不具有权威性。
- 如果本地DNS服务器本地区域文件与缓存解析都失效,则根据本地DNS服务器的设置(是否设置转发器)进行查询,如果未用转发模式,本地DNS就把请求发至13台根DNS,根DNS服务器收到请求后会判断这个域名(.com)是谁来授权管理,并会返回一个负责该顶级域名服务器的一个IP。本地DNS服务器收到IP信息后,将会联系负责.com域的这台服务器。这台负责.com域的服务器收到请求后,如果自己无法解析,它就会找一个管理.com域的下一级DNS服务器地址(qq.com)给本地DNS服务器。当本地DNS服务器收到这个地址后,就会找qq.com域服务器,重复上面的动作,进行查询,直至找到www.qq.com主机。
- 如果用的是转发模式,此DNS服务器就会把请求转发至上一级DNS服务器,由上一级服务器进行解析,上一级服务器如果不能解析,或找根DNS或把转请求转至上上级,以此循环。不管是本地DNS服务器用是是转发,还是根提示,最后都是把结果返回给本地DNS服务器,由此DNS服务器再返回给客户机。
二、搭建主辅DNS服务
2.1 测试环境:
DNS Maste | DNS Slave | httpd |
---|---|---|
系统版本:CentOS Linux release 8.1.1911 (Core) | 系统版本:CentOS Linux release 8.1.1911 (Core) | 系统版本:CentOS Linux release 7.8.2003 (Core) |
