Configure DNS experiment with bind

Use bind to configure DNS Experiment 1. experiment environment: Red Hat Enterprise Linux Server release 5.6 Host name www.2cto.com IP system version Host role%0119%2.111oel5.6server%02192.168.2.112oel5.6client%03192.168.2.113oel5.6client ..... Www.2cto.com configuration Description: The NDS server is deployed on the slave 01 (master) node, and the host names of slave 01, slave 02, and slave 03 are parsed. 2. install and configure DNS1. install bind and caching-nameserver software packages. Because the unregistered OEL version is used, yum cannot install bind software online. Install the following bind package, if it is missing, you can find and install [root @ brief 01 ~] on the installation disk. # Rpm-qa | grep bindbind-utils-9.3.6-16.P1.el5ypbind-1.19-12.el5bind-chroot-9.3.6-16.P1.el5bind-9.3.6-16.P1.el5bind-libs-9.3.6-16.P1.el5bind-libbind-devel-9.3.6-16.P1.el5bind-devel-9.3.6-16.P1.el5bind-libs-9.3.6-16.P1.el5 [root @ brief 01 ~] # Rpm-qa | grep caching-nameservercaching-nameserver-9.3.6-16.P1.el5 2. modify the name of the bind configuration file. conf and region files are all configured in the/var/named/chroot/directory. conf is under/var/named/chroot/etc/, and the region configuration file is under/var/named/chroot/var/named/. 1) modify the configuration file named. conf [root @ users 01 ~] # Cd/var/named/chroot/etc [root @ other 01 etc] # cp-p named. caching-nameserver.conf named. conf [root @ override 01 etc] # vi named. confoptions {listen-on port 53 {any;}; -- change 127.0.0.1 to 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 shocould 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 ;}; -- change localhost to any match-destinations {any ;}; -- change localhost to any recursion yes; include "/etc/named. rfc1912.zones ";}; 2) modify the configuration file named. rfc1912.zones: Add the following content to the file: [root @ 000001 etc] # pwd/var/named/chroot/etc [root @ 000001 etc] # vi named. rfc1912.zones zone "licz.com" IN {// This is your own domain name type master; file "licz.com. zone "; allow-update {none ;};}; zone" created 192.in-addr. arpa "IN {// This is the reverse configuration file type master; file" 127192.in-addr. zone "; allow-update {none ;}; 3) create leonarding.com. zone and region 192.in-addr. zon region file [root @ Issue 01 etc] # cd/var/named [root @ Issue 01 named] # cp-p localdomain. zone chroot/var/named/licz.com. zone [root @ resolve 01 named] # cp-p named. local chroot/var/named 192.zone -- modify leonarding.com. zone and region 192.in-addr. zon region file [root @ login 01 named] # cd/var/named/chroot/var/named [root @ login 01 named] # vi licz.com. zone $ TTL 86400 @ in soa localhost root (42; serial (d. adams) 3 H; refresh 15 M; retry 1 W; expiry 1D ); minimum in ns localhost // Add the following forward File Content: 201701 in a 192.168.2.11111602 in a 192.168.2.000003 in a 192.168.2.113 [root @ 000001 named] # vi LIMIT 192.in-addr. zone $ TTL 86400 @ in soa localhost. root. localhost.
