nginx: how to use multiple roots for multiple locations, including / ? (what's wrong with my pa-CodePudding

I'm trying to setup nginx for first test uses, without a domain yet.

My current goal is to show some page at http://<server IP> and serve some static content at http://<server IP>/projectname. The "some page" is currently just the default /var/www/html/index.nginx-debian.html.

In /etc/nginx/sites-available/ I've created a projectname config and I've put a link to sites-enabled:

sudo ln -s /etc/nginx/sites-available/tiddlywiki /etc/nginx/sites-enabled/

The first version of config was

server {
    listen 80;
    listen [::]:80;

    server_name <server IP>;

    root /some/path/to/project/static-files;
    index index.html;

    location /projectname {
           try_files $uri $uri/ =404;
    }
}

What I got, is http://<server IP> started serving static files, but http://<server IP>/projectname showed 404. How do I fix that? Because next step, I've followed this answer and tried to set 2 locations:

    location /projectname {
        try_files $uri $uri/ =404;
    }
    location / {
        root /var/www/html;
        index index.nginx-debian.html;
    }

but only got the default page at http://<server IP> back again, and 404 at http://<server IP>/projectname.

Ok, so the problem was, with root directive, path is concatenated to the root, so with this config

server {
    listen 80;
    listen [::]:80;

    server_name <server IP>;

    root /some/path/to/project/static-files;
    index index.html;

    location /projectname {
        try_files $uri $uri/ =404;
    }
    location / {
        root /var/www/html;
        index index.nginx-debian.html;
    }
}

nginx tried to serve /projectname → /some/path/to/project/static-files/projectname which is an unexisting folder (existing one is /some/path/to/project/static-files). What I needed is the alias directive:

server {
    listen 80;
    listen [::]:80;

    server_name <server IP>;

    index index.html;

    location /projectname {
        alias /some/path/to/project/static-files;
        index index.html;
    }
    location / {
        root /var/www/html;
        index index.nginx-debian.html;
    }
}

I'm not sure how exactly try_files works so I've removed it for now and also added the index directive.
