Root Login with Vagrant
When you create a Vagrant virtual machine, you do not get to enter your own
root password. Yes, the
vagrant user has
sudo access, but sometimes you will find yourself wanting just a little bit more. Fortunately, this is easily handled with SSH keys.
This can easily be handled as part of your provisioning process. In my
Vagrantfile, I add the following line.
config.vm.provision "shell", path: "scripts/setup_ssh.sh"
This script will create all of the necessary SSH keys and put them in the correct places.
ROOT_HOME="/root" ROOT_SSH_HOME="$ROOT_HOME/.ssh" ROOT_AUTHORIZED_KEYS="$ROOT_SSH_HOME/authorized_keys" VAGRANT_HOME="/home/vagrant" VAGRANT_SSH_HOME="$VAGRANT_HOME/.ssh" VAGRANT_AUTHORIZED_KEYS="$VAGRANT_SSH_HOME/authorized_keys" # Setup keys for root user. ssh-keygen -C root@localhost -f "$ROOT_SSH_HOME/id_rsa" -q -N "" cat "$ROOT_SSH_HOME/id_rsa.pub" >> "$ROOT_AUTHORIZED_KEYS" chmod 644 "$ROOT_AUTHORIZED_KEYS" # Setup keys for vagrant user. ssh-keygen -C vagrant@localhost -f "$VAGRANT_SSH_HOME/id_rsa" -q -N "" cat "$VAGRANT_SSH_HOME/id_rsa.pub" >> "$ROOT_AUTHORIZED_KEYS" cat "$VAGRANT_SSH_HOME/id_rsa.pub" >> "$VAGRANT_AUTHORIZED_KEYS" chmod 644 "$VAGRANT_AUTHORIZED_KEYS" chown -R vagrant:vagrant "$VAGRANT_SSH_HOME"
With this completed, you should now be able to SSH as both
$ vagrant ssh You are now logged into your VM as 'vagrant'. $ ssh root@localhost You are now logged into your VM as 'root'. # whoami root # pwd /root # exit You are now back to your VM as 'vagrant'. $ exit You are now back on your host machine. $
Hopefully this helps all the Vagrant developers out there in the world.
