ssh-agent and ssh-add automatically

Hi,

I have a linux cluster (RedHat 7.3) with 4 linux boxes. In order for ssh to operate without password I seted up private authentication keys using ssh-keygen -t rsa command. Created authorized_keys and known_hosts files and everything works fine. The problem is that every time I open a new window or start a new session I have to carry out several commands in order to use this ssh without password. The commands I need to do is following

 ssh-agent $SHELL
ssh-add

I also need to write my passphrase and only after this procedure I am able do carry out any command on any nodes directly from server without typing password or passphrase. (For example, command like ssh -n har3 date). Har3 is the name of one of the node.

What I want is to skip this procedure with ssh-agent and ssh-add commands. Is it possible to modify some configuration files of ssh so that I would be able to carry out command on nodes when I write it actually on server (like
above command ssh -n har3 date) directly when I start a new session without ssh-agent and ssh-add commands.
