Solve the problem of Nginx configuration static resource file 404 Not Found

When using nginx as a static resource server, after the configuration is completed, the 404 Not Found error is reported through the browser access. My nginx configuration information is as follows:

location /images/ {  
     root /mnt/upload/files;  
}

All files are stored in/mnt/upload/files

analyze:

It was found that it was a configuration problem. There are two ways to configure static paths. The previous configuration was to write the root directory directly in the URL, but now the configuration is a prefixed URL, so it reported a 404 Not Found error.

The root configuration will follow the configured directory and form the corresponding file path, that is, the address you want to access is:

/images/

The file path that nginx takes according to configuration is

/mnt/upload/files/images/

And what I need is

/mnt/upload/files/

Nginx provides another static path configuration: alias configuration

Official root configuration

Sets the root directory for requests. For example, with the following configuration
location /i/ {
    root /data/w3;
}
The /data/w3/i/ file will be sent in response to the “/i/” request

Official alias configuration

Defines a replacement for the specified location. For example, with the following configuration
location /i/ {
    alias /data/w3/images/;
}
on request of “/i/”, the file /data/w3/images/ will be sent.

When accessing /i/, root is to go to /data/w3/i/ to request the file, alias is to go to /data/w3/images/ to request it, that is,

The path to root response: the configured path + the full access path (full location configuration path + the static file)

The path to alias response: configuration path + static file (remove the path configured in location)

Solution:

location /images/ {  
     alias /mnt/upload/files/;  
}

Note: When using alias, you must add "/" after the directory name; generally, configure root in location/ and alias in location/*.
