查看日志tail /var/log/nginx/error.log，提示“primary script unknown while reading response header from upstream”
查看该虚拟主机的配置文件部分内容如下：
location ~ \.php {
    #fastcgi_pass remote_php_ip:9000;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
    set $real_script_name $fastcgi_script_name;
        if ($fastcgi_script_name ~ ^(.+?\.php)(/.+)$) {
        set $real_script_name $1;
        set $path_info $2;
        }
    fastcgi_param script_filename $document_root$real_script_name;
    fastcgi_param script_name $real_script_name;
    fastcgi_param path_info $path_info;
    }
无奈拷贝安装nginx后有个缺省的配置文件default中的location部分，如下：
location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #       # note: you should have cgi.fix_pathinfo = 0; in php.ini
        #
        #       # with php5-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # with php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }
重载nginx    servcie nginx reload后问题解决，
谁能解释这是为什么？
以上就介绍了nginx/146 配置的虚拟主机访问提示“file not found”，包括了file not found方面的内容，希望对php教程有兴趣的朋友有所帮助。
