Problem1 :
root@jeremy-VirtualBox:/etc/bind# /etc/init.d/bind9 restart
* Stopping domain name service... bind9 rndc: connect failed: 127.0.0.1#953: connection refused
[ OK ]
* Starting domain name service... bind9 [fail]
Solution :
默认安装BIND9以后，是无法直接使用 ndc 或 rndc 命令的。
先重新生成 rndc.conf
rndc-confgen > /etc/rndc.conf
将 rndc.conf 下面注释部分 Copy 到 /etc/rndc.key 文件中(必须将前面的#去掉)。
如：
# key "rndc-key" {
# algorithm hmac-md5;
# secret "xbPNyGOcwJp8pEJDLo26cQ==";
# };
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
如果 /etc/named.conf 中包含有 controls 这一Section，先注释掉。
然后在后面添加一行 include "/etc/rndc.key";
这样做是为了安全考虑，否则可以直接copy到 named.conf 文件中。
inet / port 的意思是，在 本机运行一个 rndc 监听端口 ，允许本机执行 ndc 或 rndc 命令。

Problem 2 : bash: etc/rndc.conf:Permission denied
Solution:
sudo sbin/rndc-confgen > etc/rndc.conf的前半部分权限的对的，只是后半部分不对。而不是一开始自己以为的使用named用户。
修改root用户密码：
sudo passwd root
输入当前普通用户的密码后，便可重新设置root密码
切换用户角色，su - 进入root用户
输入root新设置的密码后，顺利进入root权限，以后的操作就方便多了。
在root权限下，执行
sbin/rndc-confgen > etc/rndc.conf
顺利生成rndc.conf控制命令的key文件（注：符号指向：’>’是覆盖，’>>’是添加）
