求大家帮忙,按照DNS过程出的错误.

ttxx

我是按照   DNS安装配置全过程  这个帖子进行一步步的做的...做到最后一步
/usr/local/named/sbin/named -c /usr/local/named/etc/named.conf &


然后在看信息如下提示 unknown 'rndckey',,我应该如何解决???

[root@dns1 etc]# /usr/local/named/sbin/named -g
12-Jul-2007 10:09:34.406 starting BIND 9.4.1-P1 -g
12-Jul-2007 10:09:34.410 found 1 CPU, using 1 worker thread
12-Jul-2007 10:09:34.420 loading configuration from '/usr/local/named/etc/named.conf'
12-Jul-2007 10:09:34.424 /usr/local/named/etc/named.conf:16: unknown key 'rndckey'
12-Jul-2007 10:09:34.429 loading configuration: failure
12-Jul-2007 10:09:34.430 exiting (due to fatal error)



一下列出我的named.conf文件:
key "rndc-key" {
       algorithm hmac-md5;
       secret "VJ7q0ztzkcFUvgVgCc7hSg==";
};

controls {
       inet 127.0.0.1 port 953
               allow { 127.0.0.1; } keys { "rndc-key"; };
};

options {
directory "/var/named"; #named区文件目录
pid-file "named.pid"; #进程id文件名
};
controls {
        inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
        type hint;
        file "named.root";
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
};

zone "test.com" IN {
        type master;
        file "test.zone";
        allow-update { none; };
};


zone "19.202.220.in-addr.arpa" IN {
        type master;
        file "test.local";
        allow-update { none; };
};



/usr/local/named/etc/下的rndc.conf文件内容:

[root@dns1 etc]# cat rndc.conf
# Start of rndc.conf
key "rndc-key" {
        algorithm hmac-md5;
        secret "VJ7q0ztzkcFUvgVgCc7hSg==";
};

options {
        default-key "rndc-key";
        default-server 127.0.0.1;
        default-port 953;
};
# End of rndc.conf

# Use with the following in named.conf, adjusting the allow list as needed:
# key "rndc-key" {
#       algorithm hmac-md5;
#       secret "VJ7q0ztzkcFUvgVgCc7hSg==";
# };
#
# controls {
#       inet 127.0.0.1 port 953
#               allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf



/var/named目录下的文件:

named.local
localhost.zone
test.local
test.zone
named.root

一共就这些文件,请问我是哪里错了????求大家帮忙..我已经做了好几天了..都是提示这个错误....我应该怎么办...
