编写安装配置DNS服务脚本

hueel

通过脚本完成DNS自动配置，要求如下：
1、完成DNS基本配置
2、根据提示输入域名、区域文件名、记录类型、主机头、IP地址等信息完成添加域及记录的工作

#!/bin/bash
conf=/var/named/chroot/etc/named.conf
datadir=/var/named/chroot/var/named

rpm -q bind &> /dev/null
if [ $? -ne 0 ]; then
yum -y install bind bind-chroot caching-nameserver
fi

if [ ! -f $conf ];then
echo "options {
directory \"/var/named\";
};" > $conf
fi

read -p "please input domain_name:" domain
grep $domain $conf &> /dev/null
if [ $? -ne 0 ]; then
echo "zone \"$domain\" in {  
type master;
file \"$domain\";
};" >> $conf
echo "\$ttl 86400
@ in soa ${domain}. root.${domain}. (
2013010101

1d
)"> $datadir/$domain
while true
do
read -p "Type of recond(ns/a/cname/mx/ptr):" type
case $type in
ns)
echo $domain | grep "in-addr.arpa" &> /dev/null

if [ $? -eq 0 ]; then
read -p "hostname of FDQN:" fdqn
               echo "@ in      ns      $fdqn.">> $datadir/$domain

else
read -p "head of hostname:" head

如果有一双眼睛陪我一同哭泣，就值得我为生命受苦。
