I was shifting some files under SFTP in .ssh and I had accidentally replaced the id_rsa.pub in the server with my Mac Pro’s id_rsa.pub. Now I cannot connect to my server via ssh and console!
I have tried running the image backup but it does not seem to do any changes in regards to server settings.
What should I do? I have two sites hosted there and both are down.

The file on the server is ‘~/.ssh/authorized_keys’; you put your idrsa.pub in this (typically a server wouldn’t even have an idrsa.pub on it, at least not for a user account).
Console access from the DO web interface is a local terminal, so you would need to use local authentication. If you did not set a passphrase (if you preloaded your keys when creating it, there is no password set, password auth is disabled), then you would not be able to get in. There should be an option in the web interface to reset the root password; attempt this, then login via console using that password. Change that password, fix your settings, and you should be good to go.
I am not sure - I had run mysql_secure_installation before that too. After that, it keeps displaying this error : packet_write_wait: Connection to 220.127.116.11 port 22: Broken pipe

Why can’t you connect via SSH and console? id_rsa.pub server-side has nothing to do with that.
