: This article mainly introduces nginx core module Instruction 1. if you are interested in the PHP Tutorial, refer to it. Alias root
Nginx configuration has two commands for the specified directory: root and alias.
Location/img/{alias/var/www/image/;} # If you follow the preceding configuration, when accessing the files in the/img/directory, ningx will automatically go to the/var/www/image/directory to find the file Location/img/{root/var/www/image;} # If you follow this configuration, when accessing files in the/img/directory, nginx will find the file in the/var/www/image/img/Directory.]
Alias is the definition of a directory alias, while root is the definition of the top-level Directory.
Another important difference is that alias must end with "/". otherwise, files cannot be found, while root can be unavailable.
Client_body_in_file_only

Client_body_in_file_only on | off

Syntax:
Client_body_in_single_buffer
Default:

This option specifies whether to place the entire request body
A client request buffer. We recommend that you enable this option when using the $ request_body variable to reduce the overhead of the copy operation.
Client_body_buffer_size
Syntax:
Client_body_buffer_size the_size
Default:
8 k/16 k
Context:
Http, server, location
This command specifies the size of the client request body. if the size of the request body exceeds the limit, the whole or part of the request body will be written to the temporary file.
The default size is 2 pages.

Syntax:

Default:
60
Context:

This option takes effect only when the request body cannot be read at a time. if the time is exceeded, the client does not send any data, nginx returns "Request time out" (408 ). error
Client_header_buffer_size
Syntax:
Client_header_buffer_size size
Default:
1 k
Context:
Http, server
This command specifies the buffer size used to store client request headers. The default size is 1 KB, which is sufficient for most requests,
However, if a request header contains a very large cookie or the request is from a wap-client, the 1 K space cannot be accommodated, in this case, nginx will apply for a larger memory space to store the header. the larger buffer size can be obtained through
Large_client_header_buffers command.
Client_header_timeout
Syntax:
Client_header_timeout time
Default:
60
