hadoop學習筆記之-使用bind配置DNS實驗


使用bind配置DNS實驗

 

一、實驗環境:

Red Hat Enterprise Linux Server release 5.6

主機名

IP

系統版本

Host role

hotel01

192.168.2.111

OEL5.6

server

hotel02

192.168.2.112

OEL5.6

client

hotel03

192.168.2.113

OEL5.6

client

…..

 

 

 

 

配置說明:NDS服務器放在了hotel01master)節點上,對hotel01hotel02hotel03節點的主機名進行解析。

 

二、安裝配置DNS

1.安裝bindcaching-nameserver軟件包

--因使用的是未注冊的OEL版本,所以yum不能在線安裝bind軟件

--安裝下面bind包,如果缺少可以在安裝盤上查找並安裝

[root@hotel01 ~]# rpm -qa|grep bind

bind-utils-9.3.6-16.P1.el5

ypbind-1.19-12.el5

bind-chroot-9.3.6-16.P1.el5

bind-9.3.6-16.P1.el5

bind-libs-9.3.6-16.P1.el5

bind-libbind-devel-9.3.6-16.P1.el5

bind-devel-9.3.6-16.P1.el5

bind-libs-9.3.6-16.P1.el5

 

[root@hotel01 ~]# rpm -qa|grep caching-nameserver

caching-nameserver-9.3.6-16.P1.el5

 

2.修改bind配置文件

BIND的配置文件name.conf還有區域文件都在/var/named/chroot/目錄下

配置文件named.conf/var/named/chroot/etc/下,區域配置文件在/var/named/chroot/var/named/

 

1)        修改配置文件named.conf

[root@hotel01 ~]# cd /var/named/chroot/etc

[root@hotel01 etc]# cp -p named.caching-nameserver.conf named.conf

[root@hotel01 etc]# vi named.conf

options {

        listen-on port 53 { any; };--127.0.0.1改成any

        listen-on-v6 port 53 { ::1; };

        directory       "/var/named";

        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";

 

        // Those options should be used 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 {

        match-clients      { any; };--localhost改成any

        match-destinations { any; };--localhost改成any

        recursion yes;

        include "/etc/named.rfc1912.zones";

};

 

 

2)        修改配置文件named.rfc1912.zones,在文件中添加以下內容

[root@hotel01 etc]# pwd

/var/named/chroot/etc

[root@hotel01 etc]# vi named.rfc1912.zones

 

zone "licz.com" IN { //這是自己設置的域名

        type master;

        file "licz.com.zone"; 

        allow-update { none; };

};

 

zone "2.168.192.in-addr.arpa" IN { //這是反向配置文件

        type master;

        file "2.168.192.in-addr.zone";

        allow-update { none; };

};

 

3)        創建leonarding.com.zone2.168.192.in-addr.zon區域文件

[root@hotel01 etc]# cd /var/named

[root@hotel01 named]# cp -p localdomain.zone chroot/var/named/licz.com.zone

[root@hotel01 named]# cp -p named.local chroot/var/named/2.168.192.zone

 

--修改leonarding.com.zone2.168.192.in-addr.zon區域文件

[root@hotel01 named]# cd /var/named/chroot/var/named

[root@hotel01 named]# vi licz.com.zone

 

$TTL    86400

@               IN SOA  localhost root (

                                        42              ; serial (d. adams)

                                        3H              ; refresh

                                        15M             ; retry

                                        1W              ; expiry

                                        1D )            ; minimum

                IN NS           localhost

//添加下面的正向文件內容

hotel01 IN A 192.168.2.111

hotel02 IN A 192.168.2.112

hotel03 IN A 192.168.2.113

 

[root@hotel01 named]# vi 2.168.192.in-addr.zone

$TTL    86400

@       IN      SOA     localhost. root.localhost.  (

                                      1997022700 ; Serial

                                      28800      ; Refresh

                                      14400      ; Retry

                                      3600000    ; Expire

                                      86400 )    ; Minimum

        IN      NS      localhost.

//添加下面的反向向文件內容

111 IN  PTR hotel01.licz.com

112 IN  PTR hotel02.licz.com

113 IN  PTR hotel03.licz.com

 

4)        修改各節點/etc/resolv.conf文件

[root@hotel01 named]# vi /etc/resolv.conf

nameserver 192.168.2.111

 

[root@hotel02 named]# vi /etc/resolv.conf

nameserver 192.168.2.111

 

[root@hotel03 named]# vi /etc/resolv.conf

nameserver 192.168.2.111

 

 

3.驗證測試

[root@hotel01 etc]# nslookup

> hotel01.licz.com

Server:         192.168.2.111

Address:        192.168.2.111#53

 

Name:   hotel01.licz.com

Address: 192.168.2.111

> hotel02.licz.com

Server:         192.168.2.111

Address:        192.168.2.111#53

 

Name:   hotel02.licz.com

Address: 192.168.2.112

> hotel03.licz.com

Server:         192.168.2.111

Address:        192.168.2.111#53

 

Name:   hotel03.licz.com

Address: 192.168.2.113

 

[root@hotel01 named]# ping hotel03.licz.com
