All ports are open by default. The port won't be considered "open" until something is listening on it. You might have to configure it to listen on 0.0.0.0 instead of 127.0.0.1 or localhost.

How can I open a new port ?
I would like to open port 9200 on my digital ocean server for Elasticsearch. I have tried the following
sudo iptables -A INPUT -p tcp --dport 9200 -j ACCEPT
sudo ufw allow 9200
They run fine but when I check my available ports with netstat -ntulp I get cannot find them
Anyone with a suggestion ?
