nginx core module instructions 1

alias root

nginx configuration has two instructions for specifying directories, root and alias

location /img/ { alias /var/www/image/; } #若按照上述配置的话，则访问/img/目录里面的文件时，ningx会自动去/var/www/image/目录找文件location /img/ { root /var/www/image; } #若按照这种配置的话，则访问/img/目录下的文件时，nginx会去/var/www/image/img/目录下找文件。]

alias is the definition of a directory alias, and root is the definition of the top-level directory .

Another important difference is that alias must end with "/", otherwise the file will not be found, and root is optional

client_body_in_file_onlysyntax: client_body_in_file_only on|offdefault : offcontext: http, server, locationIf this option is on, the client's request body will be written to a file, and the file will not be deleted after the request is processed. , this option can be used for debugging.
client_body_in_single_buffersyntax: client_body_in_single_bufferdefault: offcontext: http, server, location This option specifies whether to put the entire request body in a client end request buffer. When using the $request_body variable, it is recommended to enable this option to reduce the cost of copy operations.

client_body_buffer_sizesyntax: client_body_buffer_size the_sizedefault: 8k/16kcontext: http, server, locationThis directive specifies the size of the client request body , if the size of the request body is exceeded, the entire request body or part will be written to a temporary fileThe default size is 2 pages.

client_header_buffer_sizesyntax: client_header_buffer_size sizedefault: 1kcontext: http, server This directive specifies the buffer used to store client request headers size. The default size is 1k, which is enough for most requests. However, if a request header contains a very large cookie, or the request comes from a wap-client, then 1k space cannot accommodate it. At this time, nginx will apply for a larger memory space to store the header. The size of this larger buffer can be specified through the large_client_header_buffers command.


client_header_timeoutsyntax: client_header_timeout timedefault: 60context: http, serverThis directive specifies the timeout for nginx to read request headers time, if it exceeds that time, then nginx will return "Request time out" (408). Error
