Padavan 老毛子 系统 ssl证书过期导致curl不能正常运行
curl 7.37.1 (mipsel-unknown-linux-gnu) libcurl/7.37.1 OpenSSL/1.0.2u zlib/1.2.8 Protocols: file ftp ftps http https Features: IPv6 Largefile NTLM NTLM_WB SSL libz
curl: (60) SSL certificate problem: certificate has expired 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.
