1.linux 訪問 https 證書問題

[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.現有 證書twca.cer 需要新增到 linux 證書信任列表

轉換格式 .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.新增後訪問就不會出現上面錯誤，
