curl SSL certificate problem

用curl装rvm环境的时候报这个错误,是本地服务器的ssl证书太旧了。

$\curl -L https://get.rvm.io | bash -s stable --without-gems="rvm rubygems-bundler"

curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
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). The default
 bundle is named curl-ca-bundle.crt; 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.

解决方法:

curl http://curl.haxx.se/ca/cacert.pem > /etc/pki/tls/certs/ca-bundle.crt.new

mv /etc/pki/tls/certs/ca-bundle.crt /etc/pki/tls/certs/ca-bundle.crt.old

mv /etc/pki/tls/certs/ca-bundle.crt.new /etc/pki/tls/certs/ca-bundle.crt

或者

curl http://curl.haxx.se/ca/cacert.pem

curl url –cacert cacert.pem 方式指定调用
