# Enable root Login
|
||
|
|
|
||
|
|
Initially the root account will be locked on all machines. You will need to
|
||
|
|
manually unlock the root account on each virtual machine.
|
||
|
|
|
||
|
|
You'll need to repeat these steps on each machine.
|
||
|
|
|
||
|
|
Login to the machine with the `vagrant` user:
|
||
|
|
|
||
|
|
`vagrant ssh@jumpbox`
|
||
|
|
|
||
|
|
Now set a password for the root account:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
sudo passwd root
|
||
|
|
```
|
||
|
|
|
||
|
|
NOTE: You can choose password **vagrant** to keep it the same as the vagrant
|
||
|
|
user, and there will be only 1 password to remember.
|
||
|
|
|
||
|
|
You'll need to unlock the password of the named account. This option re-enables
|
||
|
|
a password by changing the password back to its previous value. In this case
|
||
|
|
it should be set to the password we just assigned.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
sudo passwd -u root
|
||
|
|
```
|
||
|
|
|
||
|
|
Test that it works by running and entering the password you set:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
su
|
||
|
|
```
|
||
|
|
|
||
|
|
## Configuring SSH Access
|
||
|
|
|
||
|
|
SSH will be used to configure the machines in the cluster. Verify that you have
|
||
|
|
`root` SSH access to each machine listed in your machine database. You may need
|
||
|
|
to enable root SSH access on each node by updating the sshd_config file and
|
||
|
|
restarting the SSH server.
|
||
|
|
|
||
|
|
### Enable root SSH Access
|
||
|
|
|
||
|
|
If `root` SSH access is enabled for each of your machines you can skip this
|
||
|
|
section.
|
||
|
|
|
||
|
|
By default, a new install may disable SSH access for the `root` user. This is
|
||
|
|
done for security reasons as the `root` user has total administrative control
|
||
|
|
of unix-like systems. If a weak password is used on a machine connected to the
|
||
|
|
internet, well, let's just say it's only a matter of time before your machine
|
||
|
|
belongs to someone else. As mentioned earlier, we are going to enable `root`
|
||
|
|
access over SSH in order to streamline the steps in this tutorial. Security is
|
||
|
|
a tradeoff, and in this case, we are optimizing for convenience. Log on to each
|
||
|
|
machine via SSH using your user account, then switch to the `root` user using
|
||
|
|
the `su` command:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
su - root
|
||
|
|
```
|
||
|
|
|
||
|
|
Edit the `/etc/ssh/sshd_config` SSH daemon configuration file and set the
|
||
|
|
`PermitRootLogin` option to `yes`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sed -i \
|
||
|
|
's/^#*PermitRootLogin.*/PermitRootLogin yes/' \
|
||
|
|
/etc/ssh/sshd_config
|
||
|
|
```
|
||
|
|
|
||
|
|
Restart the `sshd` SSH server to pick up the updated configuration file:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl restart sshd
|
||
|
|
```
