安装bind
1
、安装bind软件，需要安装3 个bind、bind-chroot、bind-util
|
[root@localhost pub]#
yum install -y bind bind-chroot bind-utils
Installed:
bind.i686 32:9.8.2-0.17.rc1.el6_4.6
Complete!
|
2
、修改配置文件“/etc/named.conf”，追加“forward”
|
[root@localhost pub]#
gedit /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";
allow-query { localhost; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;
/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
forward only;
forwarders{
8.8.8.8;
}
};
|
3
、设置防火墙，这里需要用到53端口。需要开启tcp和udp的53端口，记得重启防火墙
|
[root@localhost pub]#
gedit /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT
[root@localhost phpMyAdmin]#
service iptables restart
iptables
：将链设置为政策
ACCEPT
：
filter nat [
确定
]
iptables
：清除防火墙规则：
[
确定
]
iptables
：正在卸载模块：
[
确定
]
iptables
：应用防火墙规则：
[
确定
]
iptables
：载入额外模块：
nf_conntrack_ftp [
确定
]
[root@localhost phpMyAdmin]#
|
4
、启动服务
|
[root@localhost pub]# service named start
启动
named
：
[
确定
]
[root@localhost pub]#
|
5
、测试，命令格式“dig 网站@ip”，这里用回环地址来测试，看是否能请求成功
|
[root@localhost pub]#
dig @127.0.0.1
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 <<>> @127.0.0.1
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 51491
;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;. IN A
;; ANSWER SECTION:
. 1191 IN CNAME www.a.shifen.com.
这个就是请求到的结果
;; Query time: 3053 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Tue Aug 14 19:02:59 2018
;; MSG SIZE rcvd: 90
|
6
、更改配置文件named.conf，让所有机器都可以使用该服务。
1
）将配置文件中的回环地址改为any，意味着允许任何人使用
|
[root@localhost pub]#
gedit /etc/named.conf
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; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;
/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
forward only;
forwarders{
8.8.8.8;
}
};
|
2
）找一个其他ip地址来测试
|
[root@localhost pub]#
service named restart //
重启服务
停止
named
：
[
确定
]
启动
named
：
[
确定
]
[root@localhost pub]#
dig @192.168.0.113
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 <<>> @192.168.0.113
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 37134
;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:

;; ANSWER SECTION:

;; Query time: 474 msec
