named服务记录

1.安装

rpm -ivh bind-version.rpm bind-chroot-version.rpm caching-nameserver-version.rpm bind-libs-version.rpm bind--utils-version.rpm

2.配置文件named.conf

zone "rilee.com" IN {type master; file "rilee.com.zone"; allow-transfer {192.168.0.5;};};
zone "0.168.192.in-addr.arpa" IN {type master; file "rilee.com.arpa"; allow-transfer {192.168.0.5;};};

正向文件：

反向文件：

163                         IN PTR                    mail2.rilee.com.
$GENERATE 2-222 $             IN PTR    file$.rilee.com.

3.从服务器配置：named.conf

zone "." IN {
                type hint;
                file "named.ca";
};

zone "rilee.com" IN {type slave;file "slaves/rilee.com.zone";masters {192.168.0.4;};};

zone "0.168.192.in-addr.arpa" IN {type slave;file "slaves/rilee.com.arpa";masters { 192.168.0.4;};};

4.服务启动

注意主服务器，如果默认启动的话，表面提示服务启动OK，但是实际上服务是不能正常解析的，查看日志问价tail -40 /var/log/message中有两条permission denied,是关于服务不能读取两个区域文件所致，因为named服务是用named账户运行的，所以对这两个文件没有读取权限所以不能加载。

chown ：named /var/named/chroot/var/named/rilee.com*

这样修改重启服务便可。

5.从服务启动会从主服务器这里去走那两个配置文件，权限已修改，直接通过过来就可以用了。切记，要收动修改区域文件文件序列号，时期比主服务器的小才能重新加载。

6.从服从主服务器更新这些配置文件，两者的防火前需要加条允许才行。
