Problem: How to permanently add a private key to SSH-agent?

Solution:

0. Firstly, we should know where is location folder for ssh keys. Generally it's: /home/username/.ssh/id_rsa For get this info will require input next command:

ssh-add

1. Next step, we move our key to .ssh folder that is here /home/username/.ssh/

2. Further open the file .config here /home/username/.ssh/.config and add next strings:

Host 8.8.8.8
IdentityFile ~/.ssh/our-key.pem

, where
8.8.8.8 — address of the host, also we can use domain name
~/.ssh/our-key.pem — relative path to our key

Thats all!
