    dnf -y install librados2-14.2.8 ceph-14.2.8

  3. Install ceph-deploy on the ceph1 node.
    1
    		 
    pip install ceph-deploy
  4. On ceph1, add a line of code to the _get_distro function in the /lib/python2.7/site-packages/ceph_deploy/hosts/__init__.py file to adapt the software to the openEuler system.
