ceph installation(quick)
1,preflight(ins ceph-deploy repo tools)
2,ceph storage cluster quick start
3,block device quick start
4,ceph file system quick start
5,ceph object storage quick start
(1,preflight)
Ceph is a distributed object store and file system designed to provide excellent performance, reliability and scalability
(2,ceph storage cluster quick start)
If at any point you run into trouble and you want to start over, execute the following to purge the configuration:
ceph-deploy purgedata {ceph-node} [{ceph-node}]
ceph-deploy forgetkeys
To purge the Ceph packages too, you may also execute:
ceph-deploy purge {ceph-node} [{ceph-node}]

rados(realiable automation distributed object store) 可扩展
Ceph Block Device, Ceph Filesystem ceph object store
expanding your ceph storre cluster
glassor:
ceph metadate server
ceph monitor
osd rados
mon monitor
placement group states change from active+clean to active with some degraded objects
store object data in the ceph storage cluster from ceph client:
1,set an object name
2,specify a pool
(ceph storage cluster use exercise)storage/retrieving object data:
1,map the object to a placement group
2,assign the placement group to a Ceph OSD Daemon dynamically
3,find object location(目标对象定位)
4,objectName,PoolName
1.locate an object:
rados put {object_name} {file-path} --pool=data
2.ceph storage cluster stored the object
rados -p data ls
3.identify the object location
ceph osd(object store daemon) map data ruiy-object
ceph osd map {pool-name} {object-name}
4.remove object from ceph store cluster
rados rm (rados -p data ls) --pool=data
rados put {object_name} {file_path} --pool=data
expanding ceph store cluster
1,adding an osd
ssh ruiy.cc
sudo mkdir /var/local/osd1
exit
prepare the OSD(object store daemon)
ceph-deploy osd prepare {ceph-Node}:/path/to/directory
activate the OSDs
ceph-deploy osd activate {ceph-Node}:/path/to/directory
{once you have added your new OSD,ceph will begin reblancing the cluster by migrating placement groups to your new OSD observe this process with ceph -w 查看rebalanceing the cluster placemeter group}
2,add a metadata server
to use cephFS,you need at least one metadata server,execute the following to create a metadata server
