ceph-deploy报错+解决

执行：

ceph-deploy mon create-initial

报错：

[ceph_deploy][ERROR ] KeyNotFoundError: Could not find keyring file: /etc/ceph/ceph.client.admin.keyring on host node1

[ceph_deploy][ERROR ] KeyNotFoundError: Could not find keyring file: /etc/ceph/ceph.client.admin.keyring on host node2

[ceph_deploy][ERROR ] KeyNotFoundError: Could not find keyring file: /etc/ceph/ceph.client.admin.keyring on host node3

解决：

ceph auth get-or-create client.admin mon ‘allow *’ mds ‘allow *’ osd ‘allow *’ –o /etc/ceph/ceph.client.admin.keyring

或者

ceph-create-keys --id node1

ceph-create-keys --id node2

ceph-create-keys --id node3

报错2：

[ceph_deploy.mon][ERROR]Some monitors have still not reached quorum:

[ceph_deploy.mon][ERROR]node1

解决：

暂时解决不了，从头来过就搞定了报错3：
