Answer 1

把 Server certificate这一部分拷贝出来，就是

-----END CERTIFICATE-----

存成CA.cert
openssl s_client -CAfile CA.cert -connect www.verisign.com:443

Answer 2

<VirtualHost _default_:443> 
    SSLProxyEngine on 
    SSLEngine on 
    #SSLSessionCacheTimeout  2100 
    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP 
    SSLCertificateFile /etc/httpd/common/server.crt 
    SSLCertificateKeyFile /etc/httpd/common/server.key 
    SSLCertificateChainFile /etc/httpd/common/server_intermediate.pem 
    Include conf/conf/xxx.conf 
</VirtualHost> 

这是我在apache上面的配置文件， 浏览器已经认可了证书， 但是用openssl验证的时候

CONNECTED(00000003)
depth=0 ....................
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 ........................
verify error:num=27:certificate not trusted
verify return:1
depth=0 ....................
verify error:num=21:unable to verify the first certificate
verify return:1

Verify return code: 21 (unable to verify the first certificate)

Answer 3

openssl s_client -connect www.verisign.com:443 -CApath /etc/ca-certificates

先弄明白 SSL/TLS 的具体过程，再看 man s_client。
