4、AC数据库添加、删除节点时 客户端配置信息无需修改。可以通过配置DNS服务器或GNS来配置SCAN这里以DNS为例来进行配置。2.3.1 配置DNS服务器这里 选择IP地址为76的服务器来配置DNS服务器。安装DNS包：rooe h0rdddns rp#fconf g e h0L nk encherneHWaddr 00:0C:29:99:DA:22ne addr:76 Bcas :55 Mask:ne 6 addr: fe80:20c:29e99:da22/64 Scope:L nkUP BROADCAS

18、生成正、反向数据库文件。在/var/named/chroot/var/named路径下进行配置数据库文件。利用/var/named/chroot/var/named/ oca host.zone用/var/named/chroot/var/named/ oca host.zone生成正向的数据库文件 利生成名为0.16.172. 的反向的数据库文件。说明：在 述步骤中没有配置正向Zone文件 故只需生成反向数据库文件 正向数据库文件利用默认的oca doma n.zone文件。数据库文件名一定要同 述步骤中定义的正、反向Zone文件生成的正、反向一致 否则DNS出错然后
