Centos 6.更新了最近的ca证书后,我遇到了一些麻烦.我有最新版本的curl for centos 6：
-bash-4.1$curl -V -v curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.27.1 zlib/1.2.3 libidn/1.18 libssh2/1.4.2 Protocols: tftp ftp telnet dict ldap ldaps http file https ftps scp sftp Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz
并且wget：
-bash-4.1$wget -V -v

现在我的CA https://www.certum.pl/证书有问题.卷曲工作正常：
-bash-4.1$curl -v 'https://certum.pl/' * About to connect() to certum.pl port 443 (#0) * Trying 213.222.201.147... connected * Connected to certum.pl (213.222.201.147) port 443 (#0) * Initializing NSS with certpath: sql:/etc/pki/nssdb * CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none * SSL connection using TLS_DHE_RSA_WITH_AES_256_CBC_SHA * Server certificate: * subject: CN=certum.pl,businessCategory=Private Organization,serialNumber=0000421310,incorporationState=pomorskie,incorporationLocality=Gdańsk,incorporationCountry=PL,postalCode=81-321,STREET=Podolska 21,ST=pomorskie,L=Gdynia,OU=Certification Authority Division,O=Asseco Data Systems S.A.,C=PL * start date: Aug 16 09:10:07 2017 GMT * expire date: Aug 16 09:10:07 2019 GMT * common name: certum.pl * issuer: CN=Certum Extended Validation CA SHA2,OU=Certum Certification Authority,O=Unizeto Technologies S.A.,C=PL > GET / HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.27.1 zlib/1.2.3 libidn/1.18 libssh2/1.4.2 > Host: certum.pl > Accept: */* > < HTTP/1.1 302 Found < Date: Tue,17 Jul 2018 07:02:41 GMT < Server: Apache < Pragma: no-cache < Location: https://www.certum.pl/pl/ < Content-Length: 209 < Connection: close < Content-Type: text/html; charset=iso-8859-1 < <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>302 Found</title> </head><body> <h1>Found</h1> <p>The document has moved <a href="https://www.certum.pl/pl/">here</a>.</p> </body></html> * Closing connection #0
但是wget返回ERROR：

当我在命令中指定CA证书时也会出现同样的情况 – 对于wget： – ca-certificate = / etc / pki / tls / certs / ca-bundle.crt和curl：–cacert / etc / pki / tls / certs /ca-bundle.crt
ca-certificates版本现在是2018.2.22-65.1.el6 – 最新版本. openssl版本现在是1.0.1e-57.el6 – 最新版本.
你知道发生了什么吗？
解决方法
wget链接到OpenSSL,而curl链接到NSS加密库,这可能解释了为什么它们使用不同的信任库.
我附近没有RHEL 6系统,但与OpenSSL使用的相比,rpm -ql nss可能会显示不同的/额外的信任存储.
此Red Hat资源可能与https://access.redhat.com/solutions/1549003相关
简而言之：update-ca-trust提取
