bash: /home/myuser/.ssh/authorized_keys: No such file or directory

Question: When I type in cat ~/.ssh/authorized_keys   to a RHEL 7 server I get the following message:

cat: /root/.ssh/authorized_keys: No such file or directory

I'm going through the process of setting up a SSH  to create a connection between BART and client Potgresql servers - to backup Postgresql  databases. How can I fix this issue?

Answer:You need to create the ssh directory for the first time and create the authorized keys file. 

1. Create the .ssh directory. First check if actually already exists

   mkdir ~/.ssh
   

2. Set the right permissions for the new .ssh directory. Very important step 

   chmod 700 ~/.ssh
   

3. Create the authorized_keys file (where the keys will be added)

   touch ~/.ssh/authorized_keys
   

4. Set the right permissions:

   chmod 600 ~/.ssh/authorized_keys
   

The access to the authorized keys won't work - if the right permissions are not set.

Once you've completed these steps you can add the public keys
