centos 4.4 DNS setting completely method.

[nxzwt]

(1)first install bind using "system setting"->"add/remove applications"->checked "DNS Name Server".

(2)in root user
#chkconfig --level 345 named on
#service named start

(3)edit file /etc/named.conf (actully ,this file link to /var/named/chroot/var/named/namd.conf)
add content like this:

zone "home.cn" IN {
	type master;
	file "home.cn.zone";
	allow-update { none; };
};

zone "1.168.192.in-addr.arpa" IN {
	type master;
	file "1.168.192.arpa.zone";
	allow-update { none; };
};

in this example,i will add a domain home.cn.

(4)in root user
#cd /var/named/chroot/var/named/
#su - named
#vi home.cn.zone
add content like this

$TTL	86400
home.cn.		IN SOA	cent.home.cn. root.home.cn. (
					42		; serial (d. adams)
					3H		; refresh
					15M		; retry
					1W		; expiry
					1D )		; minimum
home.cn.        IN NS		cent.home.cn.	
centos.home.cn.	IN A		192.168.1.8
home.cn.	IN MX	5	centos.home.cn.
mail		IN CNAME	centos

(note:my server's hostname is centos.home.cn.IP address is 192.168.1.8,and i give it a cname is "mail.home.cn".DNS service is also provided by this machine.)

(important: pay enough attention to the dot at the end!,it is very important!!)

#vi 1.168.192.arpa.zone
add content like this

$TTL 86400
1.168.192.in-addr.arpa.	IN SOA centos.home.cn. root.home.cn.(
20031001;
7200;
3600;
43200;
86400);

1.168.192.in-addr.arpa.	 IN	 NS 	centos.home.cn.
8	 IN 	PTR 	mail.home.cn.

(important: pay enough attention to the dot at the end!,it is very important!!)

(5)in root user
#service named restart
#service named reload

and test DNS using nslookup.

by the way,i use zimbra in centos 4.4,it works fine!

Thanks for posting that. A tip - if you highlight your code then hit the 'code' button (the # above the editing box) you'll get better formatted text for easier reading. This has also been covered in 'DNS in a nutshell' in the forums but it's always useful for a reminder.
