apache正常启动但无法访问localhost

     新安装apache+php，启动apache服务运行之后error.log日志显示：

The 'ApacheServer' service is restarting.

Starting the 'ApacheServer' service

The 'ApacheServer' service is running.

服务启动正常，但是却无法访问localhost，检查配置发现，是由于增加了配置（httpd.conf）php/ext/php_curl.dll引起，注释掉之后可以正常访问localhost。重启apache服务，此时日志显示：

关于加载库问题：LoadFile   "d:/php/ext/php_curl.dll" LoadFile   "d:/php/ssleay32.dll" 同时加载此两个库文件，将显示ssleay32.dll加载失败
