Linux操作系统下配置DNS服务器的方法介绍

Linux操作系统下配置DNS服务器的方法介绍有两台邮件服务器分别为192.168.1.1（windows下主机名为b.test.cn）和192.168.1.3（linux下主机名为a.test.com）。在linux下配置DNS服务器，下面是配置过程中设置过的一些文件，/etc/hosts文件的具体内容如下：#Donotremovethefollowingline，orvariousprograms#thatrequirenetworkfunctionalitywillfail.127.0.0.1localhost.localdomainlocalhostfc4192.168.1.3a.test.coma192.168.1.1b.test.cnb/etc/host.conf文件：orderhosts，bind表示先用hosts文件做解析，在用DNS解析/etc/resolv.conf文件：；generatedbyNetworkManager，donotedit！searchtest.comnameserver127.0.0.1searchtest.cnnameserver192.168.1.1nameserver61.144.56.100/etc/named.conf文件：////named.confforRedHatcaching-nameserver//options{directory/var/named；dump-file/var/named/data/cache_dump.db；statistics-file/var/named/data/named_stats.txt；/**Ifthereisafirewallbetweenyouandnameserversyouwant*totalkto，youmightneedtouncommentthequery-source*directivebelow.PreviousversionsofBINDalwaysasked*questionsusingport53，butBIND8.1usesanunprivileged*portbydefault.*///query-sourceaddress*port53；}；////acachingonlynameserverconfig//controls{inet127.0.0.1allow{localhost；}keys{rndckey；}；}；zone.IN{typehint；filenamed.ca；}；zonetest.comIN{typemaster；filetest.com；allow-update{none；}；}；zone1.168.192.in-addr.arpaIN{typemaster；file192.168.1.rev；allow-update{none；}；}；zonetest.cnIN{typemaster；filetest.cn；allow-update{none；}；}；zone0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpaIN{typemaster；filenamed.ip6.local；allow-update{none；}；}；zone255.in-addr.arpaIN{typemaster；filenamed.broadcast；allow-update{none；}；}；zone0.in-addr.arpaIN{typemaster；filenamed.zero；allow-update{none；}；}；include/etc/rndc.key；在/var/name/test.com文件下：$[e-mail]（42；serial（d.adams）3H；refresh15M；retry1W；expiry1D）；minimumINNSa.test.com.INMX10mail.test.com.aINA192.168.1.3mailINA192.168.1.3//其中root.a.test.com的含义是管理员的邮箱/var/name/test.cn文件下：$[e-mail]（42；serial（d.adams）3H；refresh15M；retry1W；expiry1D）；minimumINNSb.test.cn.INMX10mail.test.cn.bINA192.168.1.1mailINA192.168.1.1/var/name/192.168.1.rev文件下：$[e-mail].（1997022700；Serial28800；Refresh14400；Retry3600000；Expire86400）；MinimumINNSa.test.com.INNSb.test.cn.INMX10mail.test.com.INMX10mail.test.cn.3INPTRa.test.com.3INPTRmail.test.com.1INPTRb.test.cn.1INPTRmail.test.cn.然后用/etc/init.d/namedrestart重启DNS服务，在重启过程中，我曾经出现过好几次的错误，按照出错的提示，会提示是named.conf文件第几行出错的。或者提示在那些包含文件例如test.cn这些文件里面的问题，然后一个一个排除。最后还有一些nslookup的命令比较有用：setall用于显示使用nslookup工具这台机器上的DNS服务器的一些信息settype=any会显示完整信息包括域中邮件服务器和主从DNS服务器的名字和IP地址
