I'm pretty new to the AWS. I have created my AWS Instance and installed httpd service on it. Now, when I start httpd and open that webpage, I can see that it is running perfectly. I want to change that webpage to something else which is saved as index.html on my local machine in the documents folder. I am using Ubuntu 20.04 LTS to connect via ssh, all my key pairs are having read-only permissions. (I used chmod 400)
How can this be done?
