这里简单演示一下Apache下基于加密的认证访问----https加密方式访问。

1.DNS解析解析情况：

    [root@localhost html]# nslookup www.jb51.net

    Server:         192.168.2.115

    Address:        192.168.2.115#53

    Name:   www.jb51.net

    Address: 192.168.2.115

2.安装Apache SSL支持模块:# yum install -y mod_ssl （默认yum安装httpd是没有安装该模块的，安装后自动生产/etc/httpd/conf.d/ssl.conf文件）并生成证书。

    [root@localhost certs]# pwd

    /etc/pki/tls/certs

    [root@localhost certs]# ls

    ca-bundle.crt        index.html      localhost.crt    Makefile

    ca-bundle.trust.crt  localhost1.crt  make-dummy-cert

    [root@localhost certs]# openssl req -utf8 -new -key ../private/localhost.key -x509 -days 3650 -out abc_com.crt

    You are about to be asked to enter information that will be incorporated

    into your certificate request.

    What you are about to enter is what is called a Distinguished Name or a DN.

    There are quite a few fields but you can leave some blank

    For some fields there will be a default value,

    If you enter '.', the field will be left blank.

    -----

    Country Name (2 letter code) [XX]:CN

    State or Province Name (full name) []:510510

    Locality Name (eg, city) [Default City]:GZ

    Organization Name (eg, company) [Default Company Ltd]:ABC.COM

    Organizational Unit Name (eg, section) []:Mr.Zhang

    Common Name (eg, your name or your server's hostname) []:www.jb51.net

    Email Address []:root@abc.com

    [root@localhost certs]#

3.配置Apache，基本配置这里不多说了，下面是配置www.jb51.net站点http访问的情况。

    [root@localhost html]# tail -n 8 /etc/httpd/conf/httpd.conf

    NameVirtualhost 192.168.2.115:80

        ServerAdmin webmaster@dummy-host.example.com

        DocumentRoot /var/www/html

        ServerName www.jb51.net

        ErrorLog logs/dummy-host.example.com-error_log

        CustomLog logs/dummy-host.example.com-access_log common

    [root@localhost html]# tail /var/www/html/index.html

    www.jb51.net

    [root@localhost html]#

4.配置Apache支持https访问www.jb51.net站点，编辑 vim /etc/httpd/conf.d/ssl.conf 文件，制定www.jb51.net站点https访问时的相关信息。添加下面配置。

    DocumentRoot "/var/www/html/www.jb51.net"    #//为了显示效果，这里的站点目录不一样，一般情况一个域名应该指向同一目录的。

    ServerName www.jb51.net:443

    ErrorLog logs/ssl_error_log

    TransferLog logs/ssl_access_log

    LogLevel warn

    SSLEngine on

    SSLProtocol all -SSLv2

    SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW

    SSLCertificateFile /etc/pki/tls/certs/abc_com.crt

    SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

        SSLOptions +StdEnvVars

        SSLOptions +StdEnvVars

    SetEnvIf User-Agent ".*MSIE.*" \

             nokeepalive ssl-unclean-shutdown \

             downgrade-1.0 force-response-1.0

    CustomLog logs/ssl_request_log \

              "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

5.重启Apache服务，测试访问。

    测试http访问的结果

    测试https访问的结果

    查看证书信息和自建crt信息一致

    https访问的最终结果
