Ansible: Can't copy ssh key from one host to another?

Question

SSH

Hello! I installed Ansible on Centos 7, generated an ssh key, I try to copy it to a remote host (Ubuntu) but it says access is denied.
ssh-copy-id [email protected]###
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/ bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]###'s password:
Permission denied, please try again.
Maybe something needs to be corrected in the configs of the remote host?

Answer 1

On a remote system, remote access by root is simply prohibited.
This is usually not required.
Add a key so that the ansible goes as a regular user and specify in the playbook that it elevate privileges on the remote host (roughly speaking, the ansible will execute commands via sudo there).
ansible-playbook -i inventory.txt your-role.yml -b -K
this "-b" option become , and -K will tell ansible to ask you for your password for privilege escalation.

Answer 2

It is possible to set
PermitRootLogin yes
in /etc/ssh/sshd_config. After copying the key, you can set
PermitRootLogin prohibit-password

Answer 3

Permission denied, please try again.
most likely the possibility of root authorization via ssh is closed

Answer 4

Somehow you strangely copy it, get it through stdout and then put the action through the locale
