Hello

Yesterday I installed the LAMP stack successfully with this tutorial https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-16-04. At the end of the tutorial they say that you should secure Apache with Let’s Encrypt but that only works if you have a domain and i don’t have one.

So my question is if there are other ways to secure Apache if you only use the public ip to connect to my website?

I have set up a basic ufw firewall.

Another question I have is: Is it safe to share the public ip so people can look at my site? I have looked at this question https://www.digitalocean.com/community/questions/is-there-a-risk-to-my-website-with-my-public-ip-address but would like a better confirmation that it is safe to share it.

P.S. I don’t really need a domain since I will mainly use the site as portfolio site to show to employers and for school.

As I mentioned in that question, there is no risk. You can use a self-signed cert if you want SSL.

****Self sign the certificate

openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365

Run the command, by running this command two files are created cert.pem and key.pem , in this process it will ask few questions which are necessary to create certificate . Since we have passed days argument as 365, it is valid for another one year.
