linux dns服務(wù)器配置

1、linux dns服務(wù)器配置1. 查看服務(wù)器上是否安裝了dns服務(wù) rpm -qa | bind bind-uti-9.3.6-16.p1.el5 bind-9.3.6-16.p1.el5 rpm -qa | grep name caching-nameserver-9.3.6-16.p1.el5 需要有這幾個(gè)rpm。 2. 修改配置文件（其實(shí)精心的人會(huì)發(fā)覺(jué)次文件為鏈接文件，詳細(xì)看下文錯(cuò)誤2） /etc/nam.caching-nameserver.conf / named.caching-nameserver.conf / proved by red hat caching-nameserv

2、er package to configure the / isc bind named(8) dns server as a caching only nameserver / (as a localhost dns resolver only). / see /usr/share/doc/bind*/sample/ for ample named configuration s. / do not edit this file - use system-config-bind or an editor / to create named.conf - edits to this file

3、will be lost on / caching-nameserver package upgrade. options listen-on port 53 any; ; listen-on-v6 port 53 :1; ; directory "/var/named" mp-file "/var/named/data/cache_.db" istics-file "/var/named/data/named_stats.txt" memstatistics-file "/var/named/data/named_mem_

4、stats.txt" / those options should be u carefully because they disable port / randomization / query-source port 53; / query-source-v6 port 53; allow-query any; ; allow-query-cache any; ; logging channel default_debug file "data/named.run" severity dynamic; ; view localhost_resolver mat

5、ch-clients any; ; match-destinations any; ; recursion yes; ilude "/etc/named.rfc1912.zones" 把以上的localhost和都改成any，假如不改他只能讓主機(jī)來(lái)拜訪。 3. 在/etc/named.rfc1912.zones文件中添加一些東西 cat /etc/named.rfc1912.zones / named.rfc1912.zones: / provided by red hat caching-nameserver package / isc bind nam

6、ed zone configuration for zones recommended by / rfc 1912 section 4.1 : localhost tlds and aress zones / see /usr/share/doc/bind*/sample/ for example named configuration files. zone "." in type hint; file "named.ca" zone "localdomain" in type master; file "localdom

7、ain.zone" allow-up none; ; zone "localhost" in type master; file "localhost.zone" allow-update none; ; zone "0.0.127." in type master; file "named.local" allow-update none; ; zone ".......0

8、.0.0." in type master; file "named.ip6.local" allow-update none; ; zone "255." in type master; file "named.broadcast" allow-update none; ; zone "0." in type master; file "named.zero" allow-update none; ; zone &quo

9、t;" in type master; file "baidu.zheng" 紅色部分為添加的，意圖為正向解析 4. 上面添加的baidu.zheng文件應(yīng)當(dāng)在/var/named下面配置，進(jìn)入名目執(zhí)行 named.zero baidu.zheng，其實(shí)這個(gè)名目下面應(yīng)當(dāng)是鏈接文件，真正的文件是放在/var/named/chroot/var/named下面，copy后baidu.zheng為正確的鏈接文件就對(duì)了，否則需要到/var/named/chroot/var/named名目下面創(chuàng)建，然后修改baidu.zheng文件 cat /var/named/baidu.

10、zheng $ttl 86400 in soa localhost. root.localhost. ( 42 ; serial (d. adams) 3h ; refresh 15m ; rey 1w ; expiry 1d ) ; minimum in ns . dns in a 19 www in a 15 后面有注釋，a即address localhost.localdomain為我的主機(jī)名，主機(jī)名可以在/etc/sysconfig/network下面修改，注銷后生效 5. 重啟dns使之生效，service named restart。 6

11、. 測(cè)試： nsup ; got recursion not available from , trying next server server: address: 53 name: address: 20 nslookup server: address: 53 non-authoritative answer: canonical name = . name: address: 05 name: address: 61.135.

12、169.125 這里的錯(cuò)誤緣由是本機(jī)的dns沒(méi)有更改還是用的局域網(wǎng)內(nèi)的dns，更改dns再測(cè)試，下文的錯(cuò)誤3，有詳細(xì)說(shuō)明。 修改后測(cè)試 nslookup server: 19 address: 1953 name: address: 19 nslookup server: 19 address: 1953 name: address: 15 7. 配置反向解析在/etc/named.rfc1912.zones文件下面添加以下行 zone "247.10.

13、10." in type master; file "baidu.fan" 我的ip是10.10.247網(wǎng)段的，所以黃色部分應(yīng)當(dāng)那樣寫(xiě)，ip倒過(guò)來(lái)寫(xiě) 8. 拷貝文件cp /var/named/baidu.zheng /var/named/baidu.fan，假如拷貝后為鏈接文件就是對(duì)的，否則應(yīng)當(dāng)拷貝到/var/named/chroot/var/named，然后修改baidu.fan文件： cat baidu.fan $ttl 86400 in soa localhost. root.localhost. ( 1997022700 ; ser

14、ial 28800 ; refresh 14400 ; retry 3600000 ; expire 86400 ) ; minimum in ns . 119 in ptr . 115 in ptr . 紅色部分為修改文件，前面的119 115為ip最后一位 9. 重啟dns使之生效service named restart,然后執(zhí)行指令nslookup 19， nslookup 19 server: 19 address: 1953 0. name = .

15、 nslookup 15 server: 19 address: 1953 0. name = . service named restart 停止 named：確定 啟動(dòng) named： named配置錯(cuò)誤：: zone localdomain/in: loaded serial 42 zone localhost/in: loaded serial 42 zone 0.0.127./in: loaded serial 1997022700 zone 0.0

16、........0./in: loaded serial 1997022700 zone 255./in: loaded serial 42 zone 0./in: loaded serial 42 dns_rdata_fromtext: baidu.zheng:9: near '19.': bad dotted quad dns_rdata_fromtext: baidu.zheng:10: n

17、ear '15.': bad dotted quad zone loading master file baidu.zheng: bad dotted quad localhost_resolver/ bad dotted quad 配置正向解析的時(shí)候有這個(gè)報(bào)錯(cuò)，后來(lái)反復(fù)測(cè)試發(fā)覺(jué)在baidu.zheng文件中應(yīng)當(dāng)注重： cat baidu.zheng $ttl 86400 in soa localhost. root.localhost. ( 42 ; serial (d. adams) 3h ; refresh 15m ; retry 1w ; expi

18、ry 1d ) ; minimum in ns . dns in a 19. www in a 15. 在ip后面的.應(yīng)當(dāng)去掉，做事情應(yīng)當(dāng)仔細(xì)。 報(bào)錯(cuò)2.啟動(dòng)失敗提醒找不到文件*，一定要認(rèn)準(zhǔn)真正的名目在哪里，我這就犯了個(gè)這個(gè)問(wèn)題，其實(shí)默認(rèn)應(yīng)當(dāng)是在/var/named/下面創(chuàng)建向上文說(shuō)的baidu.zheng、baidu.fan，但是精心的人會(huì)發(fā)覺(jué)ll看一下 總計(jì) 52 drwxr-x- 6 root named 4096 02-14 22:28 chroot drwxrwx- 2 named named 4096 2011-02-23 data lr

19、wxrwxrwx 1 root named 45 2011-11-20 localdomain.zone - /var/named/chroot/var/named/localdomain.zone lrwxrwxrwx 1 root named 43 2011-11-20 localhost.zone - /var/named/chroot/var/named/localhost.zone lrwxrwxrwx 1 root named 44 2011-11-20 named.broadcast - /var/named/chroot/var/named/named.broadcast lr

20、wxrwxrwx 1 root named 37 2011-11-20 named.ca - /var/named/chroot/var/named/named.ca lrwxrwxrwx 1 root named 44 2011-11-20 named.ip6.local - /var/named/chroot/var/named/named.ip6.local lrwxrwxrwx 1 root named 40 2011-11-20 named.local - /var/named/chroot/var/named/named.local lrwxrwxrwx 1 root named 39 2011-11-20 named.zero - /var/named/chroot/var/named/named.zero drwxrwx- 2 named named 4096 2011-02-23 slaves 文件都是鏈接文件，真正的文件在/var/named/chroot/var/named下面，在這個(gè)名目先買(mǎi)年創(chuàng)建文件，可以正常啟動(dòng)，不知道為什么都是鏈接文件，大概是我安裝了rpm包然后卸載又重新安裝的緣
