DNS服务/etc/rndc.key was found解决办法

Posted 2020-12-03

RHEL6之后的版本配置好dns服务之后，会出现如下问题，rndc无法找到key，named服务跑的是正常的，其实本也可以用，但是本着不能放过一个问题的原则，找到了解决办法

 

[[email protected] named]# /etc/init.d/named status

rndc: neither /etc/rndc.conf nor /etc/rndc.key was found

named (pid  4086) is running...

[[email protected] named]# rndc status

rndc: neither /etc/rndc.conf nor /etc/rndc.key was found

 

提示没有rndc.key，主要原因还是在RHEL6上没有caching-named这个包了，EL5上是把key包含在里面的。所以我们http://www.linuxidc.com要手动创建key

 

1）创建key

[[email protected] named]# rndc-confgen -r /dev/urandom -a

wrote key file "/etc/rndc.key"

2）更改权限

[[email protected] named]# rndc status

rndc: connect failed: 127.0.0.1#953: connection refused

 

[[email protected] named]# cat /etc/rndc.key 

key "rndc-key" {

    algorithm hmac-md5;

    secret "MEARtiTMJzFfRwBKlY5lpQ==";

};

 

[[email protected] named]# ls -l /etc/rndc.key 

-rw------- 1 root root 77 May  1 06:57 /etc/rndc.key

 

[[email protected] named]# chown root:named /etc/rndc.key 

[[email protected] named]# chmod 644 /etc/rndc.key 

[[email protected] named]# rndc status

rndc: connect failed: 127.0.0.1#953: connection refused

 

重启named服务！

3）验证

[[email protected] named]# /etc/init.d/named restart

Stopping named: .                                          [  OK  ]

Starting named:                                            [  OK  ]
