shell之正向解析腳本

正向解析腳本

#!/bin/bash
yum install bind -y     //安裝解析工具包
//修改主配置文件

sed -i '13s/127.0.0.1/192.168.17.156/' /etc/named.conf  //把解析主配置文件第13行的IP地址換成192.168.17.156
sed -i '21s/localhost/any/' /etc/named.conf    //把主配置文件的21行localhost換成any
//添加內容到區域配置文件

sed -i '24azone "cwq.com" IN {\n type master;\n file "cwq.com.zone";\n allow-update { none; };\n };' /etc/named.rfc1912.zones
//區域配置文件24行後面加入域名
cd /var/named    
cp -p named.localhost cwq.com.zone   //複製模板到咱們本身設置的數據區域配置文件
//配置數據區域配置文件

sed -i '2s/@/cwq.com/2' cwq.com.zone  
sed -i '2s/rname.invalid./admin.cwq.com/' cwq.com.zone
sed -i '8s/@/cwq.com./' cwq.com.zone
sed -i '9s/127.0.0.1/192.168.17.156/' cwq.com.zone
sed -i '10aIN MX 10 mail.cwq.com.\nwww IN A 192.168.100.99\nftp IN A 192.168.100.88' cwq.com.zone
systemctl stop firewalld.service  //關閉防火牆
setenforce 0  //關閉加強功能
systemctl start named  //開啓解析服務
echo "nameserver 192.168.17.156" >/etc/resolv.conf  //把你本身的Ip地址加入解析配置文件

最後只要輸入hosts www.cwq.com就能解析出地址192.168.17.156
