nsupdate添加域名解析脚本

abc.com.adddomain 既不能用sh来执行，也不能直接用nsupdate < abc.com.adddomain 
来执行，如果nsupdate不指定-y ${key}:${secret} 会报错！

类似报错如下：

update failed: REFUSED   #感谢为我提供帮助的兄弟！

root@dns-****:/home/liuxiaojie# cat /usr/local/bind9/etc/key/key.conf  | head -n 4
key "ungeo11" {
        algorithm hmac-md5;
        secret "5I7KzWpBW7FELdtB3kNNHzFMusdnfVMQlAedFcjumUcFfA6AMUbPFUO7c0n7uyZ74eDeZp0I7tgPnD1M/uxJFw==";
};

root@dns-****:/home/liuxiaojie# cat add.sh
#!/bin/sh
cat /usr/local/bind9/etc/key/key.conf | grep key |awk  '{print  $2}' > /home/liuxiaojie/keyname.txt
cat /usr/local/bind9/etc/key/key.conf | grep secret |awk  '{print  $2}' > /home/liuxiaojie/secretname.txt
paste -d " " keyname.txt secretname.txt >all.txt
#sed -i 's/^/   /g'  secretname.txt
sed -i 's/;//g' all.txt
sed -i 's/"//g' all.txt
cat /home/liuxiaojie/all.txt | while read line
do
key=` echo $line|awk '{print $1}'`
secret=` echo $line|awk '{print $2}'`
#echo ${key}
#echo ${secret}
/usr/local/bind9/bin/nsupdate -y ${key}:${secret} <  /home/liuxiaojie/abc.com.adddomain
#echo "test"
done
使用过程中的遇到的问题：
##192.168.1.106为dns server的地址，这个nsupdate运行后有点奇怪，并不能立即在类似于 telcq.zone  telhain.zone  teljl.zone .......文件中查看到添加的相关记录，但使用dig @192.168.1.106  却可以生效！大概过个10分钟左右（我测试的） ，相关记录就会在文件里出现！

root@dns-****:/home/liuxiaojie# cat abc.com.adddomain
server 127.0.0.1
zone dccache.com
update delete abc.com.dccache.com.      CNAME
update add abc.com.dccache.com.     600 CNAME   dcc126.group.dccache.com.
send
show
quit


root@dns-****:/home/liuxiaojie# cat all.txt  |head -n 2
