主与从域名解析服务器的正反解析配置

主服务器（Centos 7 192.168.100.175）

1、构建yum仓库，用yum安装bind

 

2、关闭防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# iptables -F
[root@localhost ~]# setenforce 0

 

 3、添加本机的IP地址

[root@localhost ~]# vim /etc/resolv.conf

nameserver 192.168.100.175
nameserver 192.168.100.170

 

4、修改hosts文件，添加域名跟IP地址

[root@localhost ~]# vim /etc/hosts

192.168.100.175 ns1.crushlinux.com
192.168.100.170 ns2.crushlinux.com

 

5、修改配置文件/etc/named.conf

[root@localhost ~]# vim /etc/named.conf

 

options {
        directory       "/var/named";

};

zone "crushlinux.com" IN {
        type master;
        file "crushlinux.zheng";
        allow-transfer {192.168.100.170;};
};
zone "100.168.192.in-addr.arpa" IN {
        type master;
        file "crushlinux.fan";
        allow-transfer {192.168.100.170;};

};

 

6、在/var/named/创建crushlinux.zheng

[root@localhost ~]# vim /var/named/crushlinux.zheng

$TTL 86400
@       IN      SOA     crushlinux.com.   admin.crushlinux.com. (
                    20190817
                    3H
                    15M
                    1W
                    1D
)
           IN      NS      ns1.crushlinux.com.
           IN      NS      ns2.crushlinux.com.
           IN      MX 10   mail.crushlinux.com.
ns1     IN      A       192.168.100.175
ns2     IN      A       192.168.100.170
mail    IN      A       192.168.100.171
www   IN      A       192.168.100.172
study  IN      A       192.168.100.173
*          IN      A       192.168.100.175
ftp       IN      CNAME   www

 

7、在/var/named/创建crushlinux.fan并进行编辑

[root@localhost ~]# vim /var/named/crushlinux.fan

$TTL 86400
@       IN      SOA     crushlinux.com.         admin.crushlinux.com.(
                    20190817
                    3H
                    15M
                    1W
                    1D
)
           IN      NS      ns1.crushlinux.com.
           IN      NS      ns2.crushlinux.com.
           IN      MX 10   mail.crushlinux.com.
175     IN      PTR     ns1.crushlinux.com.
170     IN      PTR     ns2.crushlinux.com.
171     IN      PTR     mail.crushlinux.com.
172     IN      PTR     www.crushlinux.com.
173     IN      PTR     study.crushlinux.com.
175     IN      PTR     ns1.crushlinux.com.

 

8、更改文件的权限

[root@localhost ~]# chown :named /var/named/crushlinux.*

 

9、查看主配置文件是否正确

[root@localhost ~]# named-checkconf -z /etc/named.conf
zone crushlinux.com/IN: loaded serial 20190817
zone 100.168.192.in-addr.arpa/IN: loaded serial 20190817

 

10、查看正反区域数据文件是否正确

[root@localhost ~]# named-checkzone crushlinux.com /var/named/crushlinux.zheng

[root@localhost ~]# named-checkzone crushlinux.com /var/named/crushlinux.fan

 

11、重启服务，查看服务状态

[root@localhost ~]# systemctl restart named

[root@localhost ~]# systemctl status named

 

从服务器（Centos 6 192.168.100.170）

1、创建目录，挂载镜像

[root@localhost ~]# mkdir /media/cdrom

[root@localhost ~]# mount /dev/cdrom /media/cdrom

 

2、安装bind服务

[root@localhost ~]# rpm -ivh /media/cdrom/Packages/bind-9.8.2-0.17.rc1.el6_4.6.x86_64.rpm

 

3、从主服务器复制文件到从服务器

[root@localhost ~]# scp /etc/named.conf 192.168.100.170:/etc/

 

 

3、

[root@localhost ~]# service iptables stop

[root@localhost ~]# service iptables status

 

4、修改配置文件

[root@localhost ~]# cat /etc/resolv.conf

 

 

nameserver 192.168.100.175
nameserver 192.168.100.170

[root@localhost ~]# vim /etc/hosts

192.168.100.175 ns1.crushlinux.com
192.168.100.170 ns2.crushlinux.com

[root@localhost ~]# vim /etc/named.conf

options {
        directory       "/var/named";

};

zone "crushlinux.com" IN {
        type slave;
        file "slaves/crushlinux.zheng";
        masters { 192.168.100.175; };
};
zone "100.168.192.in-addr.arpa" IN {
        type slave;
        file "slaves/crushlinux.fan";
        masters { 192.168.100.175; };

};

 

4、重启

[root@localhost ~]# service named restart
