[root@www ~]# service httpd start Starting httpd: httpd: apr_sockaddr_info_get() failed for www httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName [ OK ]
2.为http主机创建一个主页
1
[root@centos6 ~]# echo "<h1>welcome to mylinuxops.com</h1>" > /var/www/html/index.html
3.测试
1 2
[root@www ~]# curl 192.168.73.2 <h1>welcome to mylinuxops.com</h1>
二、配置mylinuxopsdns1
1.安装bind服务
1
[root@mylinuxopsdns1 ~]# yum install bind -y
2.启动服务应设置为开机启动
1 2 3
[root@mylinuxopsdns1 ~]# systemctl start named [root@mylinuxopsdns1 ~]# systemctl enable named Created symlink from /etc/systemd/system/multi-user.target.wants/named.service to /usr/lib/systemd/system/named.service.
[root@mylinuxopsdns1 ~]# vim /etc/named.rfc1912.zones zone "mylinuxops.com" IN { type master; file "mylinuxops.com.zone"; };
5.创建区域数据库文件
1 2 3 4 5 6 7 8 9 10 11 12 13 14
[root@mylinuxopsdns1 ~]# cp -p /var/named/{named.localhost,mylinuxops.com.zone} [root@mylinuxopsdns1 ~]# vim /var/named/mylinuxops.com.zone $TTL 1D @ IN SOA master admin.mylinuxops.com ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS master NS slave master A 192.168.73.10 slave A 192.168.73.20 www A 192.168.73.2
6.检查语法错误
1 2 3 4
[root@mylinuxopsdns1 ~]# named-checkconf [root@mylinuxopsdns1 ~]# named-checkzone mylinuxops.com /var/named/mylinuxops.com.zone zone mylinuxops.com/IN: loaded serial 0 OK
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.68.rc1.el6 <<>> www.mylinuxops.com @192.168.73.10 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 24888 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;www.mylinuxops.com. IN A ;; ANSWER SECTION: www.mylinuxops.com. 86400 IN A 192.168.73.2 ;; AUTHORITY SECTION: mylinuxops.com. 86400 IN NS master.mylinuxops.com. ;; ADDITIONAL SECTION: master.mylinuxops.com. 86400 IN A 192.168.73.10 ;; Query time: 1 msec ;; SERVER: 192.168.73.10#53(192.168.73.10) ;; WHEN: Fri Apr 19 04:23:08 2019 ;; MSG SIZE rcvd: 89
三、配置dns从服务器mylinuxopsdns2
1.安装bind服务
1
[root@mylinuxopsdns2 ~]# yum install bind -y
2.启动dns服务设置为开机自动启动
1 2 3
[root@mylinuxopsdns2 ~]# systemctl start named [root@mylinuxopsdns2 ~]# systemctl enable named Created symlink from /etc/systemd/system/multi-user.target.wants/named.service to /usr/lib/systemd/system/named.service.
[root@mylinuxopsdns2 ~]# vim /etc/named.rfc1912.zones zone "mylinuxops.com" IN { type slave; masters {192.168.73.10;}; file "slaves/mylinuxops.zone"; };
5.检查语法错误
1
[root@mylinuxopsdns2 ~]# named-checkconf
6.重读配置文件
1
[root@mylinuxopsdns2 ~]# rndc reload
7.查看区域数据库文件是否已经被拉取到本地
1 2 3
[root@centos7 ~]# ll /var/named/slaves/ total 4 -rw-r--r-- 1 named named 298 Apr 23 04:40 mylinuxops.zone
; <<>> DiG 9.9.4-RedHat-9.9.4-72.el7 <<>> www.mylinuxops.com @192.168.73.30 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 47115 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 3 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;www.mylinuxops.com. IN A ;; ANSWER SECTION: www.mylinuxops.com. 86400 IN A 192.168.73.2 ;; AUTHORITY SECTION: mylinuxops.com. 86400 IN NS ns2.com. mylinuxops.com. 86400 IN NS ns1.com. ;; ADDITIONAL SECTION: ns1.com. 86400 IN A 192.168.73.10 ns2.com. 86400 IN A 192.168.73.20 ;; Query time: 6 msec ;; SERVER: 192.168.73.30#53(192.168.73.30) ;; WHEN: Tue Apr 23 17:25:07 CST 2019 ;; MSG SIZE rcvd: 131
五、搭建root域上的dns服务
1.安装dns服务
1
[root@rootdns ~]# yum install bind -y
2.修改主配置文件
将监听地址和允许访问的主机行注释，修改最底下的根域
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
[root@rootdns ~]# vim /etc/named.conf options { // listen-on port 53 { 127.0.0.1; }; 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"; recursing-file "/var/named/data/named.recursing"; secroots-file "/var/named/data/named.secroots"; // allow-query { localhost; }; .... zone "." IN { type master; file "root.zone"; };
3.创建根域数据库
1 2 3 4 5 6 7 8 9 10 11 12 13
[root@rootdns ~]# cp -p /var/named/{named.localhost,root.zone} [root@rootdns ~]# vim /var/named/root.zone $TTL 1D @ IN SOA ns1 admin.mylinuxops.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS ns1 com NS master ns1 A 192.168.73.40 master A 192.168.73.30
4.检查语法错误
1 2 3 4
[root@rootdns ~]# named-checkconf [root@rootdns ~]# named-checkzone . /var/named/root.zone zone ./IN: loaded serial 0 OK
5.启动dns服务
1 2 3
[root@rootdns ~]# systemctl start named [root@rootdns ~]# systemctl enable named Created symlink from /etc/systemd/system/multi-user.target.wants/named.service to /usr/lib/systemd/system/named.service.
