Setting up swcdb_cluster
swcdb_cluster uses fabric python-package
python3 -m pip install setuptools fabric;
swcdb_cluster requires password-less ssh authentication
Create a RSA-Key:
ssh-keygen -t rsa;
To pre-authorize known localhosts-addresses in-order to skip manual host key approval:
cat /root/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys; ssh-keyscan -t rsa localhost,ip6-localhost,localhost.localdomain,::1,::,127.0.0.1 >> ~/.ssh/known_hosts;
- On execution
paramiko.ssh_exception.SSHExceptionexception is raised with a message “key cannot be used for signing” or an “Unknown/Unsupported” Key or not a valid RSA private key file.
The reason can be badly-configured or broken packages distributed by the OS, an immediate possible solution is to uninstall the packages installed by the OS package manager (on Ubuntu with
apt-get remove python-paramiko python-fabric, on Archlinux
pacman -R python-paramiko python-fabric) and to install the packages available with pip.
