安装bindphp
一、安装bind软件，须要安装3 个bind、bind-chroot、bind-utilweb
| [root@localhost pub]# yum install -y bind bind-chroot bind-utilstcp
Installed:ide
bind.i686 32:9.8.2-0.17.rc1.el6_4.6 学习
Complete! 测试
|
二、修改配置文件“/etc/named.conf”，追加“forward”网站
| [root@localhost pub]# gedit /etc/named.confspa
options {rest
listen-on port 53 { 127.0.0.1; };code
# 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;
}
};
|
三、设置防火墙，这里须要用到53端口。须要开启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 [肯定]
iptables：清除防火墙规则： [肯定]
iptables：正在卸载模块： [肯定]
iptables：应用防火墙规则： [肯定]
iptables：载入额外模块：nf_conntrack_ftp [肯定]
[root@localhost phpMyAdmin]#
|
四、启动服务
| [root@localhost pub]# service named start
启动named： [肯定]
[root@localhost pub]#
|
五、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 www.baidu.com @127.0.0.1
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 <<>> www.baidu.com @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:

;; ANSWER SECTION:

|
六、更改配置文件named.conf，让全部机器均可以使用该服务。
1）将配置文件中的回环地址改成any，意味着容许任何人使用
| [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）找一个其余ip地址来测试
| [root@localhost pub]# service named restart //重启服务
中止named： [肯定]
启动named： [肯定]
[root@localhost pub]# dig www.baidu.com @192.168.0.113
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6_4.6 <<>> www.baidu.com @192.168.0.113
;; global options: +cmd
;; Got answer:

www.a.shifen.com. 299 IN A 14.215.177.38
