Linux域名解析服务实验报告DNS

一、搭建缓存域名服务器1.配置ip地址[root@localhost~]#vim/etc/sysconfig/network-scripts/ifcfg-eth0配置IP地址 配置IP地址配置IP地址BOOTPROTO=noneIPADDR=NETMASK=[root@localhost~]#servicenetworkrestart重启网卡 重启网卡重启网卡[root@localhost~]#ifconfigeth0查看网卡信息 查看网卡信息查看网卡信息eth0Linkencap:EthernetHWaddr00:0C:29:F5:12:C9inetaddr:Bcast:55Mask:2.查看并安装软件包[root@localhost~]#rpm-qbind查看软件包是否安装 查看软件包是否安装查看软件包是否安装packagebindisnotinstalled（没有安装）3.安装软件包[root@localhost~]#mount/dev/cdrom/mnt挂载光盘 挂载光盘挂载光盘mount:blockdevice/dev/cdromiswrite-protected,mountingread-only[root@localhost~]#vim/etc/yum.repos.d/rhel-debuginfo.repobaseurl=file:///mnt/Serverenabled=1安装：[root@localhost~]#yum-yinstallbind*caching-nameserver安装 安装安装Installing:bind-devel1/6Installing:bind2/6Installing:bind-sdb3/6Installing:caching-nameserver4/6Installing:bind-libbind-devel5/6Installing:bind-chroot6/6查看：[root@localhost~]#rpm-qbind查看 查看查看bind-9.3.6-4.P1.el5_4.24.配置、方法一：[root@localhost~]#cp-p/var/named/chroot/etc/named.caching-nameserver.conf/var/named/chroot/etc/named.conf复制文件 复制文件复制文件方法二：[root@localhost~]#vim/var/named/chroot/etc/named.conf直接编辑 直接编辑直接编辑添加：options{directory"/var/named"};zone"."{typehint;file"named.ca"};5.验证所配置语法是否正确[root@localhost~]#named-checkconf/var/named/chroot/etc/named.conf验证 验证验证（没有任何提示说明没有配置错误）6.重启服务[root@localhost~]#servicenamedrestart重启 重启重启停止named：[确定]启动named：[确定][root@localhost~]#netstat-anpt|grepnamed验证 验证验证7.验证（需要联网，然后nslookup能够解析公网当中的ip地址即成功）二、搭建主域名服务器1.配置[root@localhost~]#vim/var/named/chroot/etc/named.conf配置 配置配置options{directory"/var/named";};zone"."{typehint;file"named.ca";};zone""{typemaster;file".zone";};2.验证语法[root@localhost~]#named-checkconf/var/named/chroot/etc/named.conf验证语法是否有错误 验证语法是否有错误验证语法是否有错误3.创建正向区域数据文件[root@localhost~]#vim/var/named/chroot/var/named/.zone添加$TTL86400@INSOAroot(20150315011D1D1D1D)INNS.wwwINA0mailINA1ftpINA24.创建反向区域数据文件[root@localhost~]#vim/var/named/chroot/var/named/192.168.1.zone添加$TTL86400@INSOAroot(20150315011D1D1D1D)INNS.10INA011INA112INA25.验证语法[root@localhost~]#named-checkzone/var/named/chroot/var/named/.zone验证语法是否错误 验证语法是否错误验证语法是否错误zone/IN:loadedserial2015031501OK[root@localhost~]#named-checkzone/var/named/chroot/var/named/192.168.1.zone验证语法是否正确 验证语法是否正确验证语法是否正确zone/IN:loadedserial2015031501OK6.重启服务[root@localhost~]#servicenamedrestart停止named：[确定]启动named：
