1.DNS主从配置: 需要两台机器: 一台为主dns服务器，一台为从DNS服务器

a.都要安装DNS的软件： bind-chroot
b.配置主DNS服务器: allow-transfer
c.配置从DNS服务器: 不需要配置区域数据文件
d.增量更新

1.需要两台服务器一个为主一个为从
2.安装DNS软件：

yum install bind bind-chroot bind-utils bind-lib -y

3.主DNS服务器配置

vim /var/named/chroot/etc/named.conf

配置内容：

options {listen-on port 53 { any; };
#       listen-on-v6 port 53 { ::1; };directory       "/var/named";dump-file       "/var/named/data/cache_dump.db";statistics-file "/var/named/data/named_stats.txt";memstatistics-file "/var/named/data/named_mem_stats.txt";secroots-file   "/var/named/data/named.secroots";recursing-file  "/var/named/data/named.recursing";allow-query     { any; };allow-transfer {192.168.155.134; };recursion yes;pid-file "/run/named/named.pid";
};logging {channel default_debug {file "data/named.run";severity dynamic;};
};
zone "." IN {type hint;file "named.ca";
};
zone "lsj.com" IN{type master;file "lsj.zone";
};
zone "155.168.192.in-addr.arpa" IN{type master;file "155.168.192.zone";};

vim /var/named/chroot/var/named/lsj.zone

$TTL 1D
@    IN  SOA  dns1.lsj.com. test1.163.com(101D1H1W3H)IN  NS  dns1.lsj.com.IN  NS  dns2.lsj.com.IN  MX  10 mail.lsj.com.
dns1     IN  A   192.168.155.100
dns2     IN  A   192.168.155.134
mail     IN  A   192.168.155.232
ftp      IN  A   192.168.155.233
www      IN  A   192.168.155.234
ntp      IN  A   192.168.155.235
dhcp     IN  A   192.168.155.236
web      IN  CNAME  dhcp
mail.openlab.com  IN  A  192.168.155.128

3.从DNS服务器配置

vim /var/named/chroot/etc/named.conf

options {listen-on port 53 { any; };
#       listen-on-v6 port 53 { ::1; };directory       "/var/named";dump-file       "/var/named/data/cache_dump.db";statistics-file "/var/named/data/named_stats.txt";memstatistics-file "/var/named/data/named_mem_stats.txt";secroots-file   "/var/named/data/named.secroots";recursing-file  "/var/named/data/named.recursing";allow-query     { any; };recursion yes;pid-file "/run/named/named.pid";
};
logging {channel default_debug {file "data/named.run";severity dynamic;};
};
zone "." IN {type hint;file "named.ca";
};
zone "lsj.com" IN{type slave;file "slaves/lsj.zone";masters { 192.168.155.100; };
};
zone "155.168.192.in-addr.arpa" IN{type slave;file "slaves/155.168.192.zone";masters { 192.168.155.100; };
};

重启服务：

systemctl restart named-chroot

2.DNS视图的配置: 区域必须包含在视图中

view "beijing" {match-clients {192.168.155.131;};#recursion yes;zone "." IN{type hint;file "named.ca";};zone "beijing.com" IN{type master;file "beijing.zone";};
};
view "xian" {match-clients {192.168.155.133;};#recursion yes;zone "." IN{type hint;file "named.ca";};zone "xian.com" IN{type master;file "xian.zone";};
};
