5、rndc工具使用
使用rndc可以在不停止DNS服务器工作的情况下进行数据的更新，使配置生效。953提供给rndc工具用来管理DNS服务器。
# rndc-confgen > /etc/rndc.conf     //生产配置文件
### 配置内容如下：
# Start of rndc.conf
key "rndckey" {
        algorithm hmac-md5;
        secret "xO/qxwFJjYE41OrsbEAexQ==";
};
options {
        default-key "rndckey";
        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 "rndckey" {
#       algorithm hmac-md5;
#       secret "xO/qxwFJjYE41OrsbEAexQ==";
# };
#
# controls {
#       inet 127.0.0.1 port 953
#               allow { 127.0.0.1; } keys { "rndckey"; };
# };
# End of named.conf
### 结束 ###
# vim /etc/named.conf   //拷贝有 # 号注释的内容到named.conf末尾
### 添加内容如下：
### rndc.conf 2011-08-26 ###
key "rndckey" {
      algorithm hmac-md5;
      secret "xO/qxwFJjYE41OrsbEAexQ==";
};
controls {
      inet 127.0.0.1 port 953
              allow { 127.0.0.1; } keys { "rndckey"; };
};
### configure end ###
### 结束 ###
# service named restart
# rndc reload          //修改完.zone文件，使用rndc工具加载即可，可以查考第四部分进行测试
