named 主/从

安装DNS服务

yum install -y bind* caching-nameserver

将主配置文件改名为named.conf

cd /var/named/chroot/etc/
mv name.caching-nameserver.conf  named.conf

将 ip 设为 192.168.1.1/24

echo "nameserver 192.168.1.1" > /etc/resolv.conf

修改配置文件 named.conf

grep -v "^#" named.conf | grep -v "//" | grep -v "^$"

options {
    listen-on port 53 { 127.0.0.1; 192.168.1.1; };

    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";
    allow-query     { any; };
    allow-query-cache { any; };
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
view localhost_resolver {
    match-clients      { any; };
    match-destinations { any; };
    recursion yes;
    include "/etc/named.rfc1912.zones";
};

配置 named.rfc1912.zones 文件 添加：

zone "xiaozi.com" IN {
        type master;
        file "xiaozi.com.zone";
        allow-transfer    { 192.168.1.2; };   //192.168.1.2 为 从域名服务器的ip
};
zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "xiaozi.local";
        allow-transfer    { 192.168.1.2; };
};

配置 区域传送文件：xiaozi.com.zone , xiaozi.local

cd /var/named/chroot/var/named/
cp -p localhost.zone xiaozi.com.zone      //-p 可以保持文件的权限不变
cp -p named.local xiaozi.local

编辑文件：xiaozi.com.zone

将服务重启 , 设为开机自启动：

service named restart
chkconfig named on

从服务器的配置 ： 只需修改 /var/named/chroot/etc/named.rfc1912.zones , 添加：

zone "xiaozi.com" {
    type    slave;
    masters    { 192.168.1.1; };    //一定要注意格式，ip地址两旁与括号之间至少留一个空格；
    file    "slaves/xiaozi.com.zone";
};
zone "1.168.192.in-addr.arpa" {
    type    slave;
    masters    { 192.168.1.1; };
    file    "slaves/xiaozi.local";
};

然后就可以启动服务了，如果没有传送过来，可能是因为 selinux ; iptables 等的原因；

关闭selinux：

setenforce 0
getenforce
Permission

关闭防火墙：

iptables -F  或  service iptables stop

如果传送成功，可以用nslookup ; host ; dig 等命令来验证 (在从服务器上,将nameserver 指向本地即可)
