directory - How to sync two folders between two VMs Linux?

Question

I am newbie on Linux. I have a folder1 on VM1 and folder 2 on VM2. How can I configure as soon as I edit folder1, folder2 changes too. Thanks.

Answer 1

You could consider rsync (https://linux.die.net/man/1/rsync).

However I am using SCP which is a "secured copy" using my private key like so: scp -r -i /home/private_key_file what_to_copy.txt /var/projects/some_folder [email protected]:/var/projects/where_to_copy_to >> log_file_with_results.log 2>&1

So my VM2 is protected with a private key (/home/private_key_file) and I'm using user "root" to login. Hope this helps but that would be the most secure way in my opinion.

I would then run that command in a crontab every minute. For instant sync I don't know how to do so (yet), I hope that 1 minute increments are enough for you?
