1、fastcgi_bind
Syntax: fastcgi_bind address [transparent] | off; Default: — Context: http, server, location 指令在调用connect()函数之前将解析每个上游socket到一个本地地址，可以使用在主机拥有多个网卡接口或别名，但是你只允许到外的连接来自指定的网卡或者地址的情况下。
2、
fastcgi_buffering
fastcgi_buffer_size
fastcgi_buffers
fastcgi_busy_buffers_size
Syntax: fastcgi_buffering on | off; Default: fastcgi_buffering on; Context: http, server, location 开启/关闭 buffering of responses from the FastCGI server. 开启时，通过使用fastcgi_buffer_size和fastcgi_buffers的配置，使用内存缓存整个response from fastcgi ，如果一个响应的大小超过限制内存缓存的大小，a part of the response将写入临时目录，此时由fastcgi_max_temp_file_size 和 fastcgi_temp_file_write_size 控制。 关闭时，nginx将不会缓存整个response from fastcgi，从fastcgi收到数据后，及时发送给客户端。但此时也需要设置fastcgi_buffer_size（此时可以理解为缓冲区的作用） 关闭时，对CPU的要求较高，开启时，需要较大的内存。 Syntax: fastcgi_buffer_size size; Default: fastcgi_buffer_size 4k|8k; Context: http, server, location #the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform. Syntax: fastcgi_buffers number size; Default: fastcgi_buffers 8 4k|8k; Context: http, server, location #Sets thenumberandsizeof the buffers used for reading a response from the FastCGI server, for a single connection. By default, the buffer size is equal to one memory page. This is either 4K or 8K, depending on a platform. Syntax: fastcgi_busy_buffers_size size; Default: fastcgi_busy_buffers_size 8k|16k; Context: http, server, location #一般设置为fastcgi_buffer_size的两倍.
3、
fastcgi_temp_path
fastcgi_temp_file_write_size
fastcgi_max_temp_file_size
Syntax: fastcgi_temp_path path [level1 [level2 [level3]]]; Default: fastcgi_temp_path fastcgi_temp; Context: http, server, location 用法同client_body_temp_path 例如： fastcgi_temp_path /opt/nginx/fastcgi_temp 1 2; //数字2表示目录名的字符数. 如果新上传的HTTP 包体使用00000123456作为临时文件名，就会被存放在这个目录中。 /opt/nginx/fastcgi_temp/6/45/00000123456 Syntax: fastcgi_temp_file_write_size size; Default: fastcgi_temp_file_write_size 8k|16k; Context: http, server, location fastcgi 响应的 response 超过 fastcig_temp_file_write_size 限制的大小，将启用临时目录缓存response，该值的设置和fastcgi_buffer_size、fastcgi_buffers、fastcgi_max_temp_file_size相关。应大于fastcig_buffer_size，小于fastcig_max_temp_file_size，可以理解为response优先使用内存buffer，如果超过限制，才使用临时目录缓存。 Syntax: fastcgi_max_temp_file_size size; Default: fastcgi_max_temp_file_size 1024m; Context: http, server, location 该值的设置应大于fastcgi_temp_file_write_size。
4、
fastcgi_store
fastcgi_store_access
Syntax: fastcgi_store on | off | string; Default: fastcgi_store off; Context: http, server, location 用法同 proxy_store Syntax: fastcgi_store_access users:permissions ...; Default: fastcgi_store_access user:rw; Context: http, server, location 用法同 proxy_store_access
5、fastcgi_split_path_info
Syntax: fastcgi_split_path_info regex;
Default: —
Context: location
通过正则，获取pathinfo信息
例子：
location ~ ^(.+\.php)(.*)$ {
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME /path/to/php$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
6、
fastcgi_send_timeout
fastcgi_read_timeout
Syntax: fastcgi_send_timeout time; Default: fastcgi_send_timeout 60s; Context: http, server, location 如果在这个时间内，Nginx没有发送数据到fastcgi server，则connect中断。这个事件并不是request的传输超时时间。 Syntax: fastcgi_read_timeout time; Default: fastcgi_read_timeout 60s; Context: http, server, location 如果在这个时间内，Nginx没有收到fastcgi server的数据，则connect中断。这个事件并不是response的传输超时时间。
7、fastcgi_request_buffering
Syntax: fastcgi_request_buffering on | off; Default: fastcgi_request_buffering on; Context: http, server, location 开启时，Nginx读取完整的客户端请求后，才发送给fastcgi。 关闭时，Nginx收到客户端请求后，立即发送给fastcgi,增加cpu的开销.
8、
fastcgi_pass_request_body
fastcgi_pass_request_headers
fastcgi_pass_header
Syntax: fastcgi_pass_request_body on | off; Default: fastcgi_pass_request_body on; Context: http, server, location 将客户端的所有请求体传送给fastcgi server. Syntax: fastcgi_pass_request_headers on | off; Default: fastcgi_pass_request_headers on; Context: http, server, location 将客户端的所有请求体头部送给fastcgi server. Syntax: fastcgi_pass_header field; Default: — Context: http, server, location 允许某一些头部信息，传送给fastcgi server
