Your ssh key may be not config properly. Checkout following steps. 1. You get a key pair( pub key and private key). You can using the root's key which locate `/root/.ssh/id_rsa` and `/root/.ssh/id_ras.pub` or generate a new one 2. Enable the nova user login-able ``` usermod -s /bin/bash nova ``` Now you can switch nova account by using following command, and steps bellow is operated under this account. ``` su nova ``` 3. Create the folder needed by ssh and put the private key got in step 1 ``` mkdir -p /var/lib/nova/.ssh cp <private_key> /var/lib/nova/.ssh/id_rsa cat <pub_key> >> /var/lib/nova/.ssh/authorized_keys echo 'StrictHostKeyChecking no' >> /var/lib/nova/.ssh/config ``` 4. Do the steps 2-3 on each nodes. IMPORTANT: All the nodes share the same key pair and you shouldn't generate new one in second node. 5. Check the key is working properly. ``` su nova ssh nova@node-another // you will login the node-another without password ```
