使用 bind 搭建DNS 服务器
Part 1： 使用 bind 搭建DNS 服務(wù)器
軟件包：
| 1 2 3 4 5 6 7 | =========================================================================================================================== ?Package????????????????????????? Arch??????????????????? Version????????????????????????? Repository???????????????? Size =========================================================================================================================== Installing: ?bind???????????????????????????? x86_64????????????????? 32:9.9.4-14.el7????????????????? rhel-yum????????????????? 1.8 M ?bind-chroot????????????????????? x86_64????????????????? 32:9.9.4-14.el7????????????????? rhel-yum?????????????????? 81 k ?bind-dyndb-ldap????????????????? x86_64????????????????? 3.5-4.el7??????????????????????? rhel-yum?????????????????? 91 k |
??
服務(wù)名:
?named
?
1.? 安裝軟件包
yum install -y bind*
2. 設(shè)置守護(hù)進(jìn)程
| 1 2 3 | systemctl restart named systemctl enable named systemctl status named |
3. 開啟防火墻
| 1 2 3 4 | [root@localhost ~]# firewall-cmd --permanent --add-port=53/udp success [root@localhost ~]# firewall-cmd --reload success |
?4. 配置 /etc/named.conf, 開放端口訪問以及允許查詢
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | 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"; ????????allow-query???? { localhost; }; ------------> options { ????????listen-on port 53 { any; }; ????????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???? { any; }; |
5. 在文件 /etc/named.rfc1912.zones，添加定義的zone
| 1 2 3 4 5 | zone "qq.com" IN { ???????type master; ????????file "qq.zone"; ????????allow-update { none; }; }; |
?6. 配置創(chuàng)建 qq.zone 文件
| 1 2 3 4 5 | cd?/var/named/ cp??named.localhost? qq.zone 編輯qq.zone 文件 qq.com. NS desktop0.example.com. www.qq.com.? A 1.1.1.1 |
?
?7. 重啟守護(hù)進(jìn)程
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 | systemctl restart named systemctl status named ? ?

?8. 在客戶端配置DNS
| 1 | nameserver 192.168.56.12 |
?
9. 測試是否成功
| 1 2 | [root@dpf01 ~]# host www.qq.com www.qq.com has address 1.1.1.1 |
