本文档描述了在Linux环境中遇到HTTPS证书未被认可的问题，并提供了详细的解决方案。首先，通过`openssl`命令将`.cer`证书转换为`.pem`格式，然后将其追加到系统的信任证书列表 `/etc/pki/tls/certs/ca-bundle.crt`。完成这些步骤后，重新尝试访问，证书验证错误得到解决，但可能会出现401 Unauthorized错误，这通常意味着权限问题。

1.linux 访问 https 证书问题

[root@kube-node2 ~]# curl https://192.168.0.200:8443
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.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.




2.现有 证书twca.cer 需要添加到 linux 证书信任列表

转换格式 .cer 到 .pem
openssl x509 -inform der -in twca.cer  -out twca.pem
 
#追加到信任列表
cat twca.pem >> /etc/pki/tls/certs/ca-bundle.crt

[root@kube-node2 k8s]# cd /etc/kubernetes/cert/
[root@kube-node2 cert]# ls
ca-config.json  kube-controller-manager-key.pem         kubelet-client-current.pem  kubernetes-key.pem      metrics-server.pem
ca-key.pem      kube-controller-manager.pem             kubelet.crt                 kubernetes.pem
ca.pem          kubelet-client-2018-09-11-11-01-24.pem  kubelet.key                 metrics-server-key.pem
[root@kube-node2 cert]# cat ca.pem >> /etc/pki/tls/certs/ca-bundle.crt
[root@kube-node2 cert]# cat ca-key.pem >> /etc/pki/tls/certs/ca-bundle.crt




3.添加后访问就不会出现上面错误，


[root@kube-node2 cert]# curl https://192.168.0.200:8443
