Bind is the most popular software and the most widely used Domain Name System (DNS) software on the Internet for providing DNS services. The name BIND stands for “Berkeley Internet Name Domain” and it’s an implementation of the DNS protocols. In this post i will show the steps how to install and configure Bind 9 DNS service on linux CentOS 6.2 64 bit server. <\/p>\n

To install Bind 9 on linux CentOS 6.2 server, run the following command :<\/p>\n

\n[root@CentOS6.2 ~]# yum install bind -y\n<\/pre>\n

2. Setup and configure zone with the name of example.com :<\/p>\n
\n[root@CentOS6.2 ~]# vi \/var\/named\/example.com\n<\/pre>\n
Create example.com zone as below. You can have different IP addresses if you have installed separate mail server and DNS server :<\/p>\n
\n;\n;       Addresses and other host information.\n;\n@       IN      SOA     example.com. hostmaster.example.com. (\n                               2011030801      ; Serial\n                               43200      ; Refresh\n                               3600       ; Retry\n                               3600000    ; Expire\n                               2592000 )  ; Minimum\n\n;       Define the nameservers and the mail servers\n\n               IN      NS      ns.example.com.\n               IN      A       192.168.1.20\n               IN      MX      10 mail.example.com.\n\nmail            IN      A       192.168.1.20\nns              IN      A       192.168.1.20\n<\/pre>\n
3. Add example zone below to named.conf. named.conf is main configuration file for bind dns server.<\/p>\n
\nzone \"example.com\" {\n    type master;\n    file \"example.com\";\n};\n<\/pre>\n
Open named.conf :<\/p>\n
\n[root@CentOS6.2 ~]# vi \/etc\/named.conf\n<\/pre>\n
Add zone “example.com” into the named.conf as below :<\/p>\n
\n\/\/\n\/\/ named.conf\n\/\/\n\/\/ Provided by Red Hat bind package to configure the ISC BIND named(8) DNS\n\/\/ server as a caching only nameserver (as a localhost DNS resolver only).\n\/\/\n\/\/ See \/usr\/share\/doc\/bind*\/sample\/ for example named configuration files.\n\/\/\n\noptions {\n        listen-on port 53 { 127.0.0.1; };\n        listen-on-v6 port 53 { ::1; };\n        directory       \"\/var\/named\";\n        dump-file       \"\/var\/named\/data\/cache_dump.db\";\n        statistics-file \"\/var\/named\/data\/named_stats.txt\";\n        memstatistics-file \"\/var\/named\/data\/named_mem_stats.txt\";\n        allow-query     { localhost; };\n        recursion yes;\n\n        dnssec-enable yes;\n        dnssec-validation yes;\n        dnssec-lookaside auto;\n\n        \/* Path to ISC DLV key *\/\n        bindkeys-file \"\/etc\/named.iscdlv.key\";\n};\n\nlogging {\n        channel default_debug {\n                file \"data\/named.run\";\n                severity dynamic;\n        };\n};\n\nzone \".\" IN {\n        type hint;\n        file \"named.ca\";\n};\n\nzone \"example.com\" {\n    type master;\n    file \"example.com\";\n};\n\ninclude \"\/etc\/named.rfc1912.zones\";\n<\/pre>\n
4. Start named service :<\/p>\n
\n[root@CentOS6.2 ~]# service named start\n<\/pre>\n
or<\/p>\n
\n[root@CentOS6.2 ~]# \/etc\/init.d\/named start\n<\/pre>\n
5. Configure \/etc\/resolv.conf to point to this bind dns server (192.168.1.20).<\/p>\n
6. Test your dns configuration whether working or not :<\/p>\n
\n[root@CentOS6.2 ~]# host -t mx example.com\nexample.com mail is handled by 10 mail.example.com.\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
