鬱悶,簡單配置卻出錯了
1)文件/etc/named.comf 加入:
zone "xiaodao.com" IN {
type master;
file "forward.xiaodao.com";
};
zone "25.172.in-addr.arpa" IN {
type master;
file "reverse.172.25";
};
2)文件/var/named/chroot/var/named/forward.xiaodao.com
$TTL 86400
@ IN SOA mylinux.xiaodao.com. root.xiaodao.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS mylinux.xiaodao.com.
mylinux IN A 172.25.40.107
anmy IN A 172.25.10.117
ns IN CNAME mylinux
3)文件/var/named/chroot/var/named/rerverse.172.25
$TTL 86400
@ IN SOA mylinux.xiaodao.com. root.xiaodao.com. (
1 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS mylinux.xiaodao.com.
117.10 IN PTR anmy
107.40 IN PTR mylinux
4)service named start
OK
5)但是nslookup anmy.xiaodao.com
Server: 127.0.0.1
Address: 127.0.0.1#53
** server can't find anmy.xiaodao.com: SERVFAIL
為什麼呀,昨天我在另外一台電腦,還成功了..真鬱悶..

唉,原來區文件前面不能有空格
參考dogdog的文章
總結下，有兩個工具
named-checkzone命令：檢查zone文件是否正確
named-checkconf命令：檢查named.conf文件是否正確
然後遇到了一些很鬱悶的事情，最後得知是由於dogdog.com 和com.dogdog文件中的書寫格式問題，
除了（）內的不用頂格寫外，其他行都要頂格寫，不然，遇到很多不可想象的問題。
如：no current owner name ，
unknown RR type 'www'，
unknown RR type 'localhos ，
好了，習慣在於培養，養成很好的習慣就不會有很麻煩的事情了 。

最後文件如下:
1)forward.xiaodao.com
$TTL 6h
@ IN SOA mylinux.xiaodao.com. root.xiaodao.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry

IN NS mylinux.xiaodao.com.
localhost IN A 127.0.0.1
mylinux IN A 172.25.40.107
anmy IN A 172.25.10.117
ns IN CNAME mylinux.xiaodao.com.
2)reverse.172.25
$TTL 86400
@ IN SOA mylinux.xiaodao.com. root.xiaodao.com. (
1 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS mylinux.xiaodao.com.
117.10 IN PTR anmy.xiaodao.com.
107.40 IN PTR mylinux.xiaodao.com.
成功!!
