一个服务器怎么绑定两个域名

server {
    listen 443 ssl;
    server_name example1.com www.example1.com;

    ssl_certificate /etc/letsencrypt/live/example1.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example1.com/privkey.pem;

    location / {
        root /var/www/example1;
        index index.html index.htm;
    }
}

server {
    listen 443 ssl;
    server_name example2.com www.example2.com;

    ssl_certificate /etc/letsencrypt/live/example2.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example2.com/privkey.pem;

    location / {
        root /var/www/example2;
        index index.html index.htm;
    }
}
