curl - 日光浴室 - 卷曲错误 - 在 php 7 下使用 solr

Question

我正在使用 Solr 5.4，它的用户界面运行良好。

我安装了Solarium来帮助开发我的用户界面。虽然，我在尝试使用示例代码时收到此错误：

 Fatal error: Uncaught Solarium\Exception\HttpException: Solr HTTP 
 error: HTTP request failed, Connection timed out after 5001 milliseconds in solarium/library/Solarium/Core/Client/Adapter/Curl.php:195 Stack trace: #0
 solarium/library/Solarium/Core/Client/Adapter/Curl.php(92): Solarium\Core\Client\Adapter\Curl->check('', Array, Resource id #37) #1

我在运行 php7 的 CentOS 服务器下，安装了 php70w-common，它带有 php-curl，如webtatic.com 所示。Curl 和 Libcurl 也已安装。

有没有人遇到过同样的问题？

谢谢！
