更换 来此加密 ssl 证书

\cp -a /free_cicdfs0/k8s_data/registry_ssl/certs/fullchain.crt  /free_cicdfs0/k8s_data/registry_ssl/certs/domain.crt

失效 配置

能够 dig 无奈 ping

解决:
因为是局域网内非法 DNS, 所以将 DNS 平安敞开.
[root@192-168-174-42 ~]# vim /etc/named.conf
将上面的两项设置为 no
        dnssec-enable no;
        dnssec-validation no;

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, 同时不须要为了更新某个 zone 而重启 bind
