未找到php文件的NGINX文件

Nginx作爲一個web服務器。將請求傳遞給在Rails服務器上運行的獨角獸。我現在想在mysite.com/blog上安裝wordpress。因此我安裝並配置了php和fastcgi。 nginx的配置如下：

upstream unicorn_mysite { 
    server unix:/tmp/unicorn.mysite.sock fail_timeout=0; 
} 

server { 
listen 80; 
server_name mysite.com; 
return 301 https://www.$server_name$request_uri; 
} 

server { 
    listen 443 ssl; 
    ssl_certificate /opt/certs/thinbundle.crt; 
    ssl_certificate_key /opt/certs/mysite.key; 
    server_name mysite.com; 

    root /opt/www/mysite/current/public; 

    location /blog { 
      index index.php; 

      if (!-e $request_filename) { 
      rewrite ^(.*)$ /blog/index.php?q=$1 last; 
             } 

       location ~ .php(?|$) { 
        include /etc/nginx/fastcgi_params; 
        fastcgi_index index.php; 
        fastcgi_param SCRIPT_FILENAME /opt/www/mysite_wordpress$fastcgi_script_name; 
        fastcgi_pass unix:/var/run/php5-fpm.sock; 
       } 
    } 


    location ~ ^/assets/ { 
    gzip_static on; 
    expires max; 
    add_header Cache-Control public; 
    } 

    try_files $uri/index.html $uri @unicorn; 
    location @unicorn { 
    proxy_set_header Host $http_host; 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_redirect off; 
    proxy_pass http://unicorn_mysite; 
    proxy_set_header X-Forwarded-Proto $scheme; 
    add_header Front-End-Htps on; 
    } 

    error_page 500 502 503 504 /500.html; 
    client_max_body_size 4G; 
    keepalive_timeout 10; 
}

和fastcgi_params文件/ etc/nginx的/ fastcgi_params包含：

fastcgi_param QUERY_STRING  $query_string; 
fastcgi_param REQUEST_METHOD  $request_method; 
fastcgi_param CONTENT_TYPE  $content_type; 
fastcgi_param CONTENT_LENGTH  $content_length; 

fastcgi_param SCRIPT_NAME  $fastcgi_script_name; 
fastcgi_param REQUEST_URI  $request_uri; 
fastcgi_param DOCUMENT_URI  $document_uri; 
fastcgi_param DOCUMENT_ROOT  $document_root; 
fastcgi_param SERVER_PROTOCOL $server_protocol; 
fastcgi_param REQUEST_SCHEME  $scheme; 
fastcgi_param HTTPS    $https if_not_empty; 

fastcgi_param GATEWAY_INTERFACE CGI/1.1; 
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; 

fastcgi_param REMOTE_ADDR  $remote_addr; 
fastcgi_param REMOTE_PORT  $remote_port; 
fastcgi_param SERVER_ADDR  $server_addr; 
fastcgi_param SERVER_PORT  $server_port; 
fastcgi_param SERVER_NAME  $server_name; 

# PHP only, required if PHP was built with --enable-force-cgi-redirect 
fastcgi_param REDIRECT_STATUS 200;

當我去mysite.com/blog我得到這個：

當我看nginx的日誌，我看到：

2016/03/15 11:26:35 [error] 23109#23109: *29 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 185.14.209.183, server: mysite.com, request: "GET /blog HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.mysite.com"

有人可以幫我解決這個文件沒有找到。哪個文件沒有找到？它在哪裏尋找它 - 即爲什麼它找不到它！這些錯誤都不能幫助我找出問題的原因！
