nginx reverse proxy loop - nginx

Question

I need to:
point site.com to my site.github.io (that works)
point site.com/anything to filesystem /site/dist (that works)
point site2.com to site.com to filesystem /root/dist (that doesn't work, here it shows site.github.io)
site.com.conf
server {
listen 80;
server_name site.com;
location = / {
proxy_pass http://site.github.io;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
location / {
root /site/dist;
try_files $uri /index.html;
}
}
site2.com.conf
server {
listen 80;
server_name site2.com;
proxy_set_header Host site.com;
proxy_set_header X-Forwarded-For $remote_addr;
location / {
proxy_pass http://127.0.0.1/$request_uri;
}
}

Answer 1

In the case http://site2.com you're going to end up with uri = "/" when hitting site.com, which you have set to proxy to site.github.io.
You may want to do instead for site2 is:
location / {
proxy_pass http://127.0.0.1/site2/$request_uri;
}
Then in site.com:
location ~ ^/site2(.*)$ {
root /site/dist;
try_files $1 /index.html;
}
OR
location /site2 {
rewrite ^/site2(.*)$ $1 break;
root /site/dist;
try_files $uri /index.html;
}
