Apache上PHP的OpenSSL配置不起作用

我需要使用PHP在Apache2 Web服务器上使用OpenSSL，以便将Moodle和Mahara与SSO结合使用

服务器运行的是Ubuntu 10.04.3，我已经启用了SSL包，如前所述。我还遵循了设置证书的步骤。手动创建它们效果很好

但是，Mahara认为OpenSSL配置不正确：

无法生成新的SSL密钥。您确定这台机器上同时安装了openssl和openssl的PHP模块吗

这来自启动服务器后的Apache error.log：

[Thu Aug 25 10:38:06 2011] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?)

这是我在访问Maharas网络页面时得到的信息，该页面说找不到OpenSSL：

我不太明白。到底怎么了

编辑：只是澄清一下：问题似乎出在PHP上，Apache似乎很好：Apache/2.2.14 Ubuntu mod_ssl/2.2.14 OpenSSL/0.9.8k已配置-恢复正常操作

您是否正确设置了Apache虚拟主机？能否将网站的apache配置文件粘贴到要启用SSL的位置？
