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-bf06-83558f1568b4
mon initial members = itfanr
mon host = 192.168.100.61
auth cluster required = none
auth service required = none
auth client required = none
osd pool default size = 2
osd pool default pg num = 1024
osd pool default pgp num = 1024
osd crush chooseleaf type = 0
filestore 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.keyring
monmaptool --create --add itfanr 192.168.100.61 --fsid 8a9b6bf5-b7cd-4515-bf06-83558f1568b4 /tmp/monmap
mkdir /var/lib/ceph/mon/ceph-itfanr
ceph-mon --cluster ceph --mkfs -i itfanr --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
touch /var/lib/ceph/mon/ceph-itfanr/done
touch /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/sdb
sudo ceph-disk activate /dev/sdb1
