How to adjust the location block to implement path forwarding in Nginx configuration file?

Detailed explanation of Nginx path forwarding configuration

In server deployment, access paths are often required. For example, you may need to add a specific path (such as /xxxx ) after the IP address to access the original content. This article will explain in detail how to implement this function by modifying location block in the Nginx configuration file.

Scene description

Suppose your Nginx configuration file contains the following location blocks:

 location / {
    try_files $uri $uri/ /index.html;
    proxy_buffer_size 64k;
    proxy_buffers 32 32k;
    proxy_busy_buffers_size 128k;
}

location /xxxx {
    root /var/www/html;
    index index.html;
    try_files $uri $uri/ /xxxx/index.html;
}

You move the files under /var/www/html directory to /var/www/html/xxxx directory. When accessing "IP address /xxxx", Nginx still looks for index.html in the /var/www/html directory, resulting in access failure.

Cause analysis

The problem is root directive in location /xxxx block. root /var/www/html; directive specifies that Nginx finds files in the /var/www/html directory, while the try_files directive only finds files in this directory and does not change the root directory.

Solution

In order to forward the path correctly, you need to point root directive to the correct directory:

 location /xxxx {
    root /var/www/html/xxxx;
    index index.html;
    try_files $uri $uri/ /index.html;
}

After modification, when accessing "IP address /xxxx", Nginx will look for index.html in the /var/www/html/xxxx directory, thereby realizing path forwarding. Note that the try_files directive has also been adjusted to match the new file structure. If your index.html file is named differently in the /var/www/html/xxxx directory, please adjust index and try_files instructions accordingly.

Through the above modifications, you can flexibly configure Nginx to achieve various path forwarding requirements. Remember, root directive determines the root directory of Nginx search files, while the path in location block defines the virtual path. Only by using the two together can the correct path mapping be achieved.
