<hr><p>由 fei 发布于: 2001-02-12 11:16</p><p> </p><p>1. 有关域名的说明<br> TCP/IP域名影响TCP/IP主机的地址翻译，即主机名到地址的转换。此外，域名也影响邮件交换，即邮件地址到邮件服务器的映射。<br> Internet上的域名通常带有后缀，但实际配置中可以不给出后缀。<br> 域名系统包括域名服务器(DNS)和域名客户机。<br> 一个TCP/IP客户(如MS Windows)通常通过以下几种方式查找某个主机的地址：<br> · 使用HOSTS文件，在该文件中给出名字/地址表；<br> · 使用WINS协议，给出WINS服务器地址；<br> · 使用DNS，这时需要给出域名服务器(DNS)地址。<br><br>2. 相关文件<br> 和DNS配置相关的文件包括：<br> · /etc/defaultdomain<br> · /etc/nsswitch.conf<br> · /etc/resolv.conf<br> · /etc/named.boot<br> · 以及和具体域名配置的"主机"、"本地网络"、"反向"、"Cache"等四个文件。<br> 这里的四个文件的路径以及文件名均在文件"/etc/named.boot"中给出。<br> 以下的示例中，路径使用"/var/named"，四个文件分别为named.hosts，named.local，named.rev和named.ca。<br> 以上文件权限只需root可读即可。<br><br>3. DNS具体配置说明<br> (1) /etc/defaultdomain<br> "/etc/defaultdomain"文件给出确省域名，该文件内容为域名名称，例如：<br> so.unis<br> 表示缺省域名为"so.unis"，以后仅使用某个主机名时，系统假设为缺省域中的主机。例如，"ping www"将被理解为"ping <a href="http://www.so.unis"。" target=_blank>http://www.so.unis"。</a><br> (2) /etc/nsswitch.conf<br> 如果使用DNS，则必须在该文件的"HOST"一项中给出"DNS"。缺省为使用文件，即"FILES"，该选项可以保留。<br> 例如：<br> # /etc/nsswitch.files:<br> …<br> hosts: dns files<br> …<br> (3) /etc/resolv.conf<br> 该文件给出域名和域名服务器地址。<br> 例如：<br> ; /etc/resolv.conf file <br> domain so.unis ;域名<br> nameserver 192.168.99.1 ;域名服务器地址<br> ;域名服务器地址可以给出多个<br> (4) /etc/named.boot<br> 该文件指明DNS所需具体文件的路径和文件名。<br> 例如：<br> ; named.boot file<br> directory /var/named<br> ;文件所在路径，通常使用/var/named<br> cache . named.ca ;dns cache file,其中点表示当前域<br> primary so.unis named.hosts ;dns host file<br> secondary unis 192.168.0.1 ;另一个域"unis"的DNS地址<br> primary 0.0.127.in-addr.arpa named.local<br> ;local dns file，127.0.0.0为本地子网<br> primary 99.168.192.in-addr.arpa named.rev<br> ;named rev file，本子网为192.168.99.0 <br><br>(5) /var/named/named.hosts<br>说明如下：<br>; named.hosts - dns file<br>;<br>; SOA rec<br>so.unis.
