### HttpFcgi模塊 這個模塊允許Nginx 與FastCGI 進程交互，并通過傳遞參數來控制FastCGI 進程工作。 配置實例: ~~~ location / { fastcgi_pass localhost:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/www/scripts/php$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; } ~~~ 語法： ### fastcgi_buffers ~~~ syntax: fastcgi_buffers the_number is_size; default: fastcgi_buffers 8 4k/8k; context: http, server, location 該指令集設置緩沖區的數量和大小，用于緩存從 FastCGI Server 接收到的數據。默認情況下，一個緩沖區的大小相當于一個頁面的大小。根據平臺的不同設置為4K/8K ~~~ ### fastcgi_buffer_size syntax: fastcgi_buffer_size the_size default: fastcgi_buffer_size 4k/8k context: http, server, location This directive sets the buffersize, into which will be read the first part of the response, obtained from the fastcgi server. In this part of response the small response-header is located, as a rule. By default, the buffersize is equal to the size of one buffer in directive fastcgi_buffers; however, it is possible to set it to less. ### fastcgi_cache syntax: fastcgi_cache zone; default: none context: http, server, location 設置緩存在共享內存中的名稱. 一塊區域可以被用于不用的地方. ### fastcgi_cache_key syntax: fastcgi_cache_key line?; default: none context: http, server, location 設置緩存的key, 例: ~~~ fastcgi_cache_key localhost: 9000 $ request_uri; ~~~ ### fastcgi_cache_methods syntax: fastcgi_cache_methods [GET HEAD POST]; default: fastcgi_cache_methods GET HEAD; context: main,http,location GET/HEAD is syntax sugar, i.e. you can not disable GET/HEAD even if you set just ~~~ fastcgi_cache_methods POST; ~~~ ### fastcgi_cache_min_uses syntax: fastcgi_cache_min_uses n default: fastcgi_cache_min_uses 1 context: http, server, location TODO: Description. ### fastcgi_cache_path syntax: fastcgi_cache_path /path/to/cache [levels=m:n keys_zone=name:time inactive=time clean_time=time] default: none context: http, server, location TODO: Description. ### fastcgi_cache_use_stale ~~~ syntax: fastcgi_cache_use_stale [updating|error|timeout|invalid_header|http_500] default: fastcgi_cache_use_stale off; context: http, server, location TODO: Description. ~~~ ### fastcgi_cache_valid ~~~ syntax: fastcgi_cache_valid [http_error_code|time] default: none context: http, server, location TODO: Description. ~~~ ### fastcgi_index ~~~ syntax: fastcgi_index file default: none context: http, server, location The name of the file which will be appended to the URI and stored in the variable $fastcgi_script_name if URI concludes with a slash. ~~~ ### fastcgi_hide_header ~~~ syntax: fastcgi_hide_header name context: http, server, location 默認情況下Nginx 不會從FastCGI 進程里給客戶端發送"Status" 和"X-Accel-..." 消息頭。這個指令可以用來掩飾別的headers 。 如果需要"Status" 和"X-Accel-..." 消息頭，那就需要使用這個指令讓FastCGI 強制發送消息頭給客戶端。 ~~~ ### fastcgi_ignore_client_abort ~~~ syntax: fastcgi_ignore_client_abort on|off default: fastcgi_ignore_client_abort off context: http, server, location 這個指令用來決定忽略用戶取消的請求。 ~~~ ### fastcgi_intercept_errors ~~~ syntax: fastcgi_intercept_errors on|off default: fastcgi_intercept_errors off context: http, server, location 這個指令用來決定是否要把客戶端轉向4xx和5xx錯誤頁，或允許Nginx自動指定錯誤頁頁。 注意：你需要在此明確錯誤頁,它才是有用的。Igor 曾說：“如果沒有定制的處理機制，Nginx不會攔截一個沒有缺省頁的錯誤。Nginx 只會攔截一些小的錯誤，放過其他一些。 ~~~ ### fastcgi_param ~~~ syntax: fastcgi_param parameter value default: none context: http, server, location 該指令指定的參數,將被傳遞給FastCGI-server。 它可能使用字符串、變量及其它們的組合來作為參數值。如果不在此制定參數，它就會繼承外層設置；如果在此設置了參數，將清除外層相關設置，僅啟用本層設置。 下面是一個例子,對于PHP來說的最精簡的必要參數： fastcgi_param SCRIPT_FILENAME /home/www/scripts/php$fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; 參數SCRIPT_FILENAME 是PHP 用來確定執行腳本的名字，而參數QUERY_STRING 是它的一個子參數。 如果要處理POST,那么這三個附加參數是必要的： fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; 如果PHP 在編譯時使用了--enable-force-cgi-redirect選項，設置參數REDIRECT_STATUS 的值為200就是必須的了。 fastcgi_param REDIRECT_STATUS 200; ~~~
