broken trust chain resolving 'baidu.com/AAAA/IN': 114.114.114.114#53
解决:
由于是局域网内非法DNS,所以将DNS安全关闭.

curl: (60) Peer's Certificate issuer is not recognized.
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.

1、953端口是rndc 的端口
2、rndc是监控bind的统计数据用的,同时不需要为了更新某个zone而重启bind
