使用BIND安装智能DNS服务器（二）---配置rndc远程控制

首先两个BIND DNS服务器要正常运行。

主DNS服务器IP：192.168.1.100

客户机DNS服务器IP：192.168.1.101

1 主DNS端配置：

cd /etc/

生成rndc.conf文件

rndc-confgen > rndc.conf

查看文件

cat rndc.conf

# Start of rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "VcL5wC2GHCzCU7ju+ajC1Q==";
};

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 "VcL5wC2GHCzCU7ju+ajC1Q==";
# };
# 
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf

vim named.conf

将下面这些添加到named.conf末尾

//支持远程rndc控制
key "rndc-key" {
algorithm hmac-md5;
secret "VcL5wC2GHCzCU7ju+ajC1Q==";
};

//inet: 如果只允许本地使用rndc控制把*换为127.0.0.1
//allow: 允许通过rndc管理此DNS的IP、KEY，这里设置为客户端IP
controls {
inet * port 953    
allow { localhost; 192.168.1.101; } keys { "rndc-key"; }; 
};

删除rndc.key

rm rndc.key -f

重启BIND

service named restart

2 客户端配置

cd /etc/

生成rndc.conf文件

rndc-confgen > rndc.conf

编辑文件，修改secret为主DNS服务器配置中的值

vim rndc.conf

# Start of rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "VcL5wC2GHCzCU7ju+ajC1Q==";
};

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 "VcL5wC2GHCzCU7ju+ajC1Q==";
# };
# 
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf
