====== Install and configure ceph-rgw ======

On the machine where ceph radosgw will be installed:

<code bash>
yum clean all
yum update

useradd ceph-deploy
passwd ceph-deploy
echo "ceph-deploy ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph-deploy

</code>


cepl-deploy@ceph-adm key on the node where radosgw will be installed:

<code bash>
[ceph-deploy@ceph-adm ~]$ ssh-copy-id ceph-deploy@ceph-rgw-02
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/ceph-deploy/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
ceph-deploy@ceph-rgw-02's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'ceph-deploy@ceph-rgw-02'"
and check to make sure that only the key(s) you wanted were added.

[ceph-deploy@ceph-adm ~]$ ssh ceph-rgw-02 hostname
ceph-rgw-02.cloud.pd.infn.it
[ceph-deploy@ceph-adm ~]$

Disable SELinux

Modify ceph.conf on all ceph cluster nodes and all openstack nodes adding:
