If you are using Linux and want to securely connect to servers without using a username password, you can create a ssh key and connect to remote server by copying ssh key to that server. Thus, you can connect to servers without a username password and securely.<\/p>\n

How To Create ssh key in Centos?<\/h3>\n

Before creating ssh key, you need to login with the user you want to create ssh key, or you need to switch to that user.<\/p>\n

We run the following command to create ssh key.<\/p>\n

ssh-keygen -t rsa<\/pre>\n
\"\"<\/p>\n
After running the command, our ssh keys were created under the \/home\/frks\/.ssh directory seen above.<\/p>\n
How To Copy ssh key to Another Server?<\/h3>\n
Let’s make ssh by copying our ssh key to a different server from the machine we are on. We must copy our ssh key to remote server to connect without username and password as below.<\/p>\n
ssh-copy-id remote_user_name@remote_server_we_want_to_copy_our_sshkey<\/pre>\n
Sample Usage:<\/p>\n
ssh-copy-id frks@instance-2<\/pre>\n
We copied the ssh key to instance-2 server with the frks user with the above command.<\/p>\n
\"\"<\/p>\n
After copying the SSH key, we can connect with ssh as follows.<\/p>\n
ssh frks@instance-2<\/pre>\n
