ceph 清理和手动部署N版

卸载osd

df | grep ceph | awk '{print $NF}' | xargs -n1 umount

删除ceph

rm -rf /var/lib/ceph

rm -rf /var/log/ceph

rm -rf /etc/ceph/*

systemctl stop ceph-radosgw.target

systemctl stop ceph-crash.service

systemctl status ceph-crash.service

rm -rf /var/log/radosgw

卸载ceph rpm包

rpm -qa | grep ceph | xargs -n1 yum -y remove

rm /etc/yum.repos.d/ceph*.repo -f

rpm -qa | grep rados | xargs -n1 yum remove -y

yum remove -y python-rados

5.1 单台 Ceph 节点宕机处理步骤

登陆 ceph monitor 节点，查询 ceph 状态：

ceph health detail

将故障节点上的所有 osd 设置成 out，该步骤会触发数据 recovery, 需要等待数据迁移完成, 同时观察虚拟机是否正常：

ceph osd out osd_id

从 crushmap 将 osd 移除，该步骤会触发数据 reblance，等待数据迁移完成，同时观察虚拟机是否正常：

ceph osd crush remove osd_name

删除 osd 的认证： ceph auth del osd_name

删除 osd ：ceph osd rm osd_id

清理lvm残留，卸载osd重新启用盘时使用。

lvdisplay | grep "LV Path" | awk '{print $NF}' | xargs -i lvremove -f {}

vgdisplay | grep "VG Name" | awk '{print $NF}' | xargs -i vgremove {}

pvremove /dev/sd[b-j]

ceph-volume lvm list

ls /dev/mapper/

systemctl stop ceph-osd@8.service

umount -l

umount -l /var/lib/ceph/osd/ceph-8

1. 安装

生成fsid

uuidgen

生成秘钥环

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 –cap mon 'allow *' –cap osd 'allow *' –cap mds 'allow *' –cap mgr 'allow *'

ceph-authtool –create-keyring /var/lib/ceph/bootstrap-osd/ceph.keyring –gen-key -n client.bootstrap-osd –cap mon 'profile bootstrap-osd' –cap mgr 'allow r'

ceph-authtool /tmp/ceph.mon.keyring –import-keyring /etc/ceph/ceph.client.admin.keyring

ceph-authtool /tmp/ceph.mon.keyring –import-keyring /var/lib/ceph/bootstrap-osd/ceph.keyring

chown ceph:ceph /tmp/ceph.mon.keyring

monmaptool –create –add node1 10.33.132.50 –add node3 10.33.132.52 –add node4 10.33.132.53 –fsid a5303bea-c6ba-4690-9fb2-49ed046be391 /tmp/monmap

monmaptool –print /tmp/monmap

创建默认数据目录

mkdir /var/lib/ceph/mon/ceph-node1

chmod 777 -R /var/lib/ceph/mon/ceph-node1

分发配置文件, 启动mon节点

scp /etc/ceph/ceph.conf node2:/etc/ceph/ceph.conf

chown -R ceph:ceph /var/lib/ceph/mon/ceph-node3

chown -R ceph:ceph /var/lib/ceph/mon/ceph-node4

systemctl start ceph-mon@node1 && systemctl enable ceph-mon@node1

systemctl status ceph-mon@node1

systemctl start ceph-mon@node3 && systemctl enable ceph-mon@node3

systemctl status ceph-mon@node1

systemctl start ceph-mon@node4 && systemctl enable ceph-mon@node4

systemctl status ceph-mon@node1

ceph -s 查看状态

mon is allowing insecure global_id reclaim

ceph config set mon auth_allow_insecure_global_id_reclaim false

关闭不安全的回收模式

3 monitors have not enabled msgr2

ceph mon enable-msgr2

创建MGR

在运行ceph-mon守护程序的每个节点上，还应该设置一个ceph-mgr守护程序。

创建密钥目录

所有mgr节点都要执行

sudo -u ceph mkdir /var/lib/ceph/mgr/ceph-`hostname -s`

cd /var/lib/ceph/mgr/ceph-`hostname -s`

ceph auth get-or-create mgr.`hostname -s` mon 'allow profile mgr' osd 'allow *' mds 'allow *' > keyring

systemctl enable ceph-mgr@`hostname -s` && systemctl start ceph-mgr@`hostname -s`

查看osd fsid,看下是否已经存在

# 新建RADOSGW用户和keyring

ceph-authtool –create-keyring /etc/ceph/ceph.client.radosgw.keyring

chown ceph:ceph /etc/ceph/ceph.client.radosgw.keyring

ceph-authtool -n client.rgw.node6 –cap osd 'allow rwx' –cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring

将keyring导入集群中

ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.rgw.node1 -i /etc/ceph/ceph.client.radosgw.keyring

ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.rgw.node2 -i /etc/ceph/ceph.client.radosgw.keyring
