ここに私の apache2/conf.d/php5-fpm.conf があります:

<IfModule mod_fastcgi.c>
        AddHandler php5-fcgi .php
        Action php5-fcgi /php5-fcgi
        Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi
        FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -appConnTimeout 10 -idle-timeout 250 -socket /tmp/php5-fpm.sock -pass-header Authorization
</IfModule>

誰かが私を助けることができますか？
