bind程序包:
bind:提供的dns server程序、以及幾個常用的測試程序;
bind-libs:被bind和bind-utils包中的程序共同用到的庫文件;
bind-utils:bind客戶端程序集,例如dig, host, nslookup等;
bind-chroot:選裝,讓named運(yùn)行于jail模式下;
對三臺主機(jī)分別更改主機(jī)名 關(guān)閉防火墻以及關(guān)閉selinux (iptables和selinux保存配置后需要重啟服務(wù)才能生效)
nod1更改主機(jī)
[root@nod1 ~]# vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=nod1.wupeng.com
nod2更改主機(jī)
[root@nod2 ~]# vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=nod2.wupeng.com
nod3更改主機(jī)
[root@nod3 ~]# vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=nod3.wupeng.com
nod1清空防火墻規(guī)則
[root@nod1 ~]# iptables -F [root@nod1 ~]# service iptables save
nod2清空防火墻規(guī)則
[root@nod2 ~]# iptables -F [root@nod2 ~]# service iptables save
nod3清空防火墻規(guī)則
[root@nod3 ~]# iptables -F [root@nod3 ~]# service iptables save
nod1關(guān)閉selinux安全機(jī)制
[root@nod1 ~]# vim /etc/sysconfig/selinux 或者 vim /etc/selinux/config SELINUX=disabled
nod2關(guān)閉selinux安全機(jī)制
[root@nod2 ~]# vim /etc/sysconfig/selinux 或者 vim /etc/selinux/config SELINUX=disabled
nod3關(guān)閉selinux安全機(jī)制
[root@nod3 ~]# vim /etc/sysconfig/selinux 或者 vim /etc/selinux/config SELINUX=disabled
三臺主機(jī)分別同步時間為一致 可以使用ntpdate命令來進(jìn)行時間同步
[root@nod1 ~]# yum install ntpdate -y
[root@nod2 ~]# yum install ntpdate -y
[root@nod3 ~]# yum install ntpdate -y
[root@nod1 ~]# ntpdate ntp.api.bz
28 Jun 15:42:08 ntpdate[1598]: step time server 17.253.84.125 offset 856096.191423 sec
[root@nod2 ~]# ntpdate ntp.api.bz
28 Jun 15:42:08 ntpdate[1577]: step time server 17.253.84.125 offset 854843.947376 sec

可以進(jìn)行全量傳輸區(qū)域數(shù)據(jù) 一般是不允許的 所以我們要進(jìn)行安全配置
在主機(jī)nod1主配置文件上配置acl 只允許從服務(wù)器傳輸 全局之外定義
[root@nod1 named]# vim /etc/named.conf acl slaves { 10.208.131.228; }; [root@nod1 named]# vim /etc/named.rfc1912.zones zone "wupeng.com" IN { type master; file "wupeng.com.zone"; allow-transfer { slaves; }; allow-update { none; }; }; zone "131.208.10.in-addr.arpa" IN { type master; file "10.208.131.zone"; allow-transfer { slaves; }; allow-update { none; }; };
重新加載服務(wù)
[root@nod1 named]# rndc reload
server reload successful
在主機(jī)nod2上配置文件不進(jìn)行更新
zone "wupeng.com" IN { type slave; file "slaves/wupeng.com"; masters { 10.208.131.222; }; allow-transfer { none; }; allow-update { none; }; }; zone "131.208.10.in-addr.arpa" IN { type slave; file "slaves/10.208.131.zone"; masters { 10.208.131.222; }; allow-transfer { none; }; allow-update { none; }; };
重新加載服務(wù)
[root@nod2 slaves]# rndc reload
server reload successful
