CentOS設定DNS管網域

基本設定請參
CentOS安裝dns (forward only)

新增一個zone

• #vi /etc/named.rfc1912.conf
• zone "ne94.kirnel.com" IN {
•         type master;
•         file "ne94.zone";
•         allow-update { none; };
• };

建立ne94.zone檔案的內容

• #cd /var/named/chroot/var/named/
• #cp localhost.zone ne94.zone
• #vi ne94.zone
• $TTL    86400
  
• @               IN SOA  @       root (
  
•                                         2009101601              ; serial (d. adams) --->序號
  
•                                         3H              ; refresh
  
•                                         15M             ; retry
  
•                                         1W              ; expiry
  
•                                         1D )            ; minimum
  
• 
  
•                 IN NS           @
  
•                 IN A            127.0.0.1
  
•                 IN AAAA         ::1
  
• www          IN A            123.123.123.123 --->新增設定
  
• w3              IN CNAME        www --->新增設定

變更 ne94.zone的權限

• #chown root.named ne94.zone
• -rw-r----- 1 root  named  195  7月 30 08:56 localhost.zone
  
• -rw-r----- 1 root  named  427  7月 30 08:56 named.zero
  
• -rw-r----- 1 root  root   247 10月 15 16:14 ne94.zone
