Bind master-slave replication and subdomain authorization

The positive and negative areas of bind are resolved as follows

Second, from the DNS configuration file/etc/named.conf and the primary DNS configuration,

[[email protected] ~]# vim /etc/named.conf          listen-on port 53 { 127.0.0.1; 192.168.3.8; };         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";          #allow-query     { localhost; };                                     recursion yes; [[email protected] ~]# named-checkconf                     #检查主配置文件

Edit the zone file/etc/named.rf1912.zones, followed by add positive and negative parsing, as follows:

[Email protected] ~]# Vim/etc/named.rfc1912.zoneszone "magedu.com" in {type slave;        Masters {192.168.3.9;};        File "slaves/magedu.com"; allow-update {none;};};        Zone "3.168.192.in-addr.arpa" in {type slave;        Masters {192.168.3.9;};        File "Slaves/192.168.3.zone"; allow-update {none;};};

Iv. master/Slave synchronization

The master server adds a record [[email protected] named]# vim /var/named/magedu.com.zone  $TTL  86400$ Origin magedu.com.@       in      soa      ns1.magedu.com. admin.magedu.com  (         2016110401        1H         5M        7D         1D)         IN      NS       ns1.magedu.com.        IN       NS      ns2.magedu.com.         IN      MX      10       mx1        in      mx       20      mx2ns1     IN       a       192.168.3.9ns2     in       A       192.168.3.9mx1      IN      A        192.168.3.9mx2     in      a        192.168.3.9www     IN      A        192.168.3.9jym     IN       cname   wwwimg     in      a        192.168.3.9                 #添加的A记录 

Primary DNS Reread configuration file

[[Email protected] named]# service named Reload reload named: [OK]

To prevent synchronization failures, Selinux,iptables release should be turned off.
