马哥博客作业第九周
1、配置 bind 服务，实现 www.magedu.org 域名解析
[root@88 ~]vim /etc/named.conf
listen-on port 53 { loaclhost; };
allow-query { any; };
dnssec-enable no;
dnssec-validation no;
[root@88 ~]vim /etc/named.rfc1912.zones
zone "magedu.org" { type master; file "magedu.org.zone"; };
[root@88 ~]cp -p /var/named/named.localhost /var/named/magedu.org.zone
[root@88 ~]vim /var/named/magedu.org.zone
$TTL 1D @ IN SOA master admin ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS master master A 10.0.0.88 www A 10.0.0.99
[root@88 ~]named-checkconf [root@88 ~]named-checkzone magedu.org /var/named/magedu.org.zone [root@88 ~]rndc reload
2、配置 bind 服务，实现域名反向解析
[root@88 ~]#vim /etc/named.rfc1912.zones
zone "0.0.10.in-addr.arpa" { type master; file "10.0.0.zone"; };
[root@88 ~]#cp -p /var/named/named.loopback /var/named/10.0.0.zone
[root@88 ~]#vim /var/named/10.0.0.zone
$TTL 1D @ IN SOA ns admin.magedu.org. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS ns.magedu.org. 99 PTR www.magedu.org.
[root@88 ~]#named-checkzone 0.0.10.in-addr.apra /var/named/10.0.0.zone root@88 ~]#rndc reload
3、配置 bind 服务，实现主从 DNS 服务配置：
主服务器配置:
[root@88 ~]#vim /etc/named.conf
dnssec-enable no;
dnssec-validation no;
allow-transfer {10.0.0.99;};
[root@88 ~]#vim /var/named/magedu.org.zone
$TTL 1D @ IN SOA master admin ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS master master A 10.0.0.88 www A 10.0.0.99 slave A 10.0.0.99
[root@88 ~]#named-checkconf [root@88 ~]#named-checkzone magedu.org /var/named/magedu.org.zone [root@88 ~]#rndc reload
从服务器配置:
[16:20:27 root@99 ~]#yum install named named-utils -y;systemctl enable --now named.service
[16:21:51 root@99 ~]#vim /etc/named.conf
//listen-on port 53 { 127.0.0.1; };
//allow-query { localhost; }; allow-transfer {none;};
[16:23:08 root@99 ~]#vim /etc/named.rfc1912.zones
zone "magedu.org" { type slave; masters {10.0.0.88;}; file "slaves/magedu.org.slave"; };
[16:24:27 root@99 ~]#named-checkconf [16:25:25 root@99 ~]#rndc reload
[16:25:30 root@99 ~]#ls /var/named/slaves/magedu.org.slave var/named/slaves/magedu.org.slave
[16:28:45 root@99 ~]#cat /etc/resolv.conf # Generated by NetworkManager nameserver 10.0.0.88 nameserver 10.0.0.99
4、 配置 bind 服务，实现子域服务器：
父域服务器配置:10.0.0.8
[root@8 ~]#yum install bind-utils -y;systemctl enable --now named.service
[root@8 ~]#vim /etc/named.conf options { //listen-on port 53 { 127.0.0.1; }; //allow-query { localhost; }; allow-transfer {10.0.0.18;}; dnssec-enable no; dnssec-validation no;
[root@8 ~]#cp -p /var/named/named.localhost /var/named/magedu.org.zone
[root@8 ~]#vim /var/named/magedu.org.zone
$TTL 1D
@ IN SOA master admin (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS master
shanghai NS shanghains
master A 10.0.0.8
shanghains A 10.0.0.18
websrv A 10.0.0.77
www CNAME websrv
[root@8 ~]#named-checkconf [root@8 ~]#named-checkzone magedu.org /var/named/magedu.org.zone zone magedu.org/IN: loaded serial 0 OK
[root@8 ~]#rndc reload
server reload successful
子域服务器配置:10.0.0.18
[17:40:11 root@18 ~]#yum install bind bind-utils -y;systemctl enable --now named
[17:40:11 root@18 ~]#vim /etc/named.conf options { //listen-on port 53 { 127.0.0.1; }; //allow-query { localhost; }; allow-transfer {none;}; dnssec-enable no; dnssec-validation no;
[17:40:11 root@18 ~]#vim /etc/named.conf options { //listen-on port 53 { 127.0.0.1; }; //allow-query { localhost; }; allow-transfer {none;}; dnssec-enable no; dnssec-validation no;
[17:41:22 root@18 ~]#vim /etc/named.rfc1912.zones zone "shanghai.magedu.org" { type master; file "shanghai.magedu.org.zone"; };
[17:41:54 root@18 ~]#cp -p /var/named/named.localhost /var/named/shanghai.magedu.org.zone
[17:41:54 root@18 ~]#vim /var/named/shanghai.magedu.org.zone $TTL 1D @ IN SOA master admin.magedu.org. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS master master A 10.0.0.18 websrv A 10.0.0.78 www CNAME websrv
[17:44:08 root@18 ~]#named-checkconf [17:44:23 root@18 ~]#named-checkzone shanghai.magedu.org /var/named/shanghai.magedu.org.zone zone shanghai.magedu.org/IN: loaded serial 0 OK
[17:44:27 root@18 ~]#rndc reload
server reload successful
[17:44:42 root@18 ~]#vie0 DNS1=127.0.0.1
[17:45:32 root@18 ~]#nmcli c reload
[17:45:58 root@18 ~]#nmcli c up eth0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
父域的web服务器:10.0.0.77
[17:27:53 root@77 ~]#yum install httpd -y ;systemctl enable --now httpd;echo "`hostname -I`" >/var/www/html/index.html [17:27:57 root@77 ~]#cat /var/www/html/index.html 10.0.0.77
子域的web服务器:10.0.0.78
[root@78 ~]#yum install httpd -y ;systemctl enable --now httpd;echo "`hostname -I`" >/var/www/html/index.html
[root@78 ~]#cat /var/www/html/index.html
