创建Pool
# ceph osd pool create volumes 64
# ceph osd pool create images 64
# ceph osd pool create vms 64
配置centos7 ceph yum源
在glance-api（控制节点）节点上
yum install python-rbd -y
（计算节点）在nova-compute和cinder-volume节点上
yum install ceph-common -y
集群ceph存储端操作
[root@ceph ~]# ssh controller sudo tee /etc/ceph/ceph.conf < /etc/ceph/ceph.conf
[root@ceph ~]# ssh compute sudo tee /etc/ceph/ceph.conf < /etc/ceph/ceph.conf
如果开启了cephx authentication，需要为Nova/Cinder and Glance创建新的用户，如下
ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rx pool=images'
ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images'
为client.cinder, client.glance添加keyring，如下
ceph auth get-or-create client.glance | ssh controller sudo tee /etc/ceph/ceph.client.glance.keyring
ssh controller sudo chown glance:glance /etc/ceph/ceph.client.glance.keyring
ceph auth get-or-create client.cinder | ssh compute sudo tee /etc/ceph/ceph.client.cinder.keyring
ssh compute sudo chown cinder:cinder /etc/ceph/ceph.client.cinder.keyring
为nova-compute节点上创建临时密钥
ceph auth get-key client.cinder | ssh {your-compute-node} tee client.cinder.key
此处为
ceph auth get-key client.cinder | ssh compute tee client.cinder.key
在所有计算节点上(本例就只有一台计算节点)执行如下操作：在计算节点上为libvert替换新的key
uuidgen
536f43c1-d367-45e0-ae64-72d987417c91
cat > secret.xml <<EOF
粘贴以下内容，注意将红色key替换为新生成的key。
<secret>
<uuid>536f43c1-d367-45e0-ae64-72d987417c91</uuid>
<usage>
<name>client.cinder secret</name>
</usage>
</secret>
EOF
virsh secret-define --file secret.xml
以下—base64 后的秘钥为计算节点上/root目录下的client.cinder.key。是之前为计算节点创建的临时秘钥文件
virsh secret-set-value 536f43c1-d367-45e0-ae64-72d987417c91 AQCliYVYCAzsEhAAMSeU34p3XBLVcvc4r46SyA==
