THANKS for the answer kamaln7 :)

It worked the first time, after I restart the nginx service again, the css style and images weren't loaded. The page is plain text html without css, and if I press a link from it, it redirects me to http://my_public_id page instead of the page it supposed to if I open it from http://my_public_id:8069

this is my nginx configuration btw

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        root /var/www/***/***;
        index index.php index.html index.htm;

        server_name ***;

        error_page 404 /404.html;

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
                root /usr/share/nginx/html;
        }


        location / {
            # try_files $uri $uri/ =404;
            try_files $uri $uri/ /index.php?$args;
        }

        #location /profile {
        #   proxy_pass http://127.0.0.1:8069;
        #   proxy_redirect off;
        #   proxy_set_header    Host            $host;
        #   proxy_set_header    X-Real-IP       $remote_addr;
        #   proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        #   proxy_set_header X-Forwarded-Proto $scheme;
        #}# I used ^ this before you replied :)

        location /profile/ {
            rewrite ^/profile(/.*)$ $1 break;
            proxy_pass  http://localhost:8069/;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
            proxy_redirect    off;
        }

        location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }
}

I picked up a thing or two about configuring nginx these past two days, I think i need to familiarize myself to rewrite and regex.

thank you very much
