小编给大家分享一下ceph怎么一步步手动创建，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

手动创建ceph.conf文件

[root@manila61 ceph-manila61]# cat /etc/ceph/ceph.conf [global]fsid = 8a9b6bf5-b7cd-4515-bf06-83558f1568b4mon initial members = itfanrmon host = 192.168.100.61  auth cluster required = noneauth service required = noneauth client required = noneosd pool default size = 2 osd pool default pg num = 1024osd pool default pgp num = 1024osd crush chooseleaf type = 0filestore xattr use omap = true

依次执行

ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'ceph-authtool --create-keyring /etc/ceph/ceph.client.admin.keyring --gen-key -n client.admin \ --set-uid=0 --cap mon 'allow *' --cap osd 'allow *' --cap mds 'allow'ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyringmonmaptool --create --add itfanr 192.168.100.61  --fsid 8a9b6bf5-b7cd-4515-bf06-83558f1568b4  /tmp/monmapmkdir /var/lib/ceph/mon/ceph-itfanrceph-mon --cluster ceph  --mkfs -i itfanr  --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyringtouch /var/lib/ceph/mon/ceph-itfanr/donetouch /var/lib/ceph/mon/ceph-itfanr/sysvinit

注意：sysvinit空文件一定要创建。否则启动mon时会提示：

/etc/init.d/ceph: mon.irfanr not found (/etc/ceph/ceph.conf defines , /var/lib/ceph defines )

然后执行：ceph -s 看看集群信息。

增加osd

ceph-disk zap /dev/sdb ceph-disk -v prepare  --fs-type xfs --cluster-uuid 8a9b6bf5-b7cd-4515-bf06-83558f1568b4  /dev/sdbsudo ceph-disk activate /dev/sdb1
