How to use ssh to run a local .sh file (present on a local linux machine) on a remote linux machine (an AWS ec2 instance)

Question

I am having a tough time figuring out a way to execute a .sh file present on my local linux machine on to a remote linux machine which happens to be an AWS ec2 instance. Here's what I am doing on my local machine:

ssh -i sample.pem ec2-user@server_name.amazon.com 'bash -s' < file_to_remotely_execute.sh

Error that I get is:

Warning: Identity file sample.pem not accessible: No such file or directory. Pseudo-terminal will not be allocated because stdin is not a terminal. Host key verification failed.

This was referred to arrive at the above approach.

Answer 1

Possible issues :

1. The PEM file doesn't exist.
2. The PEM file doesn't have proper permissions.
3. The host is not allowed in ~/.ssh/known_hosts file.

Solutions :

1. Navigate to the location where PEM file exists or give full path of PEM file.
2. Give 400 permissions to the PEM file, ( sudo chmod 400 /path/to/file.pem ).
3. Login to the server by ssh once, and allow the host.
