nginx specify a file path in two ways root and alias

 

background

      Never understand this configuration What do you mean, anyway, make do with it, but the old makeshift total is not a thing, not understood more easily forgotten, others also asked not answer. Anyway, it is also very simple, you do understand the point down.

Knowledge Point

root Example: 

^ ~ LOCATION / T / { 
     the root / WWW / the root / HTML /; 
} 

When the request is a URI if /t/a.html, web server will return / www / root / html / t / a on the server. the html file. 

alias example: 

location ^~ /t/ {
 alias /www/root/html/new_t/;
}

If a requested URI is /t/a.html time, web server will return /www/root/html/new_t/a.html of files on the server. Note that this is new_t, because the path behind the location of the alias will discard configuration, to match the current directory to the specified directory points. 

note:

1. When using the alias, the directory name must be added "/."
3. alias when using a regular match, must capture content to be matched and used at the specified content.
4. alias location located block only. (Root can not be placed in the location)
