Nginx dynamic wildcard subdomain for dynamic url of a domain

Question

I want to configure nginx.conf for the below url

domain.com/user/suvojit => suvojit.domain.com

Till now my nginx configuration is as below

server {
listen 80; ## listen for ipv4

server_name domain.com;
root        /var/www/html/project/frontend/web/;
index       index.php;

access_log  /var/www/html/project/vagrant/nginx/log/frontend-access.log;
error_log   /var/www/html/project/vagrant/nginx/log/frontend-error.log;

location / {
    try_files $uri $uri/ /index.php$is_args$args;
}

location ~ \.php$ {
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    try_files $uri =404;
}

location ~ /\.(ht|svn|git) {
    deny all;
}}

I am using Yii2 application. Is there anything need to specify there?

Answer 1

You need to had a server block to your nginx config

server {

listen 80; ## listen for ipv4

server_name ~^(?<user>[^.]+)\.example\.com$;

return 301 http://example.com/user/$user;

}

You also need to make sure that you make a wildcard subdomain entry in your DNS so that *.domain.com resolves to your server
