前面已经介绍了Ceph的自动部署，本次介绍一下关于手动部署Ceph节点操作
一台虚拟机部署单节点Ceph集群
IP：172.25.250.14
内核： Red Hat Enterprise Linux Server release 7.4 (Maipo)
磁盘：/dev/vab,/dev/vac,/dev/vad
[root@cepe5 ~]# yum install -y ceph-common ceph-mon ceph-mgr ceph-mds ceph-osd ceph-radosgw
登录到ceph5查看ceph目录是否生成
[root@ceph5 ceph]# ll -rw-r--r-- 1 root root 92 Nov 23 2017 rbdmap [root@ceph6 ~]# ll /etc/ceph/ -rw-r--r-- 1 root root 92 Nov 23 2017 rbdmap
执行uuidgen命令，得到一个唯一的标识，作为ceph集群的ID
[root@ceph5 ceph]# uuidgen 82bf91ae-6d5e-4c09-9257-3d9e5992e6ef
生成ceph配置文件
[root@ceph5 ceph]# vim /etc/ceph/backup.conf
fsid = 51dda18c-7545-4edb-8ba9-27330ead81a7 mon_initial_members = ceph5 mon_host = 172.25.250.14 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx public_network = 172.25.250.0/24 cluster_network = 172.25.250.0/24 [mgr] mgr modules = dashboard [client.rgw.ceph5] host = ceph5 keyring = /etc/ceph/backup.client.rgw.ceph5.keyring log_file=/var/log/ceph/$cluster.$name.log rgw_frontends = civetweb port=80 rgw_print_continue = false rgw_dns_name = lab.example.com
设置集群名为backup
[root@ceph5 ceph]# vim /etc/sysconfig/ceph
创建monitor使用的key
[root@ceph5 ceph]# ceph-authtool --create-keyring /tmp/backup.mon.keyring --gen-key -n mon. --cap mon ‘allow *‘
为ceph amin用户创建管理集群的密钥并赋予访问权限
[root@ceph5 ceph]# ceph-authtool --create-keyring /etc/ceph/backup.client.admin.keyring --gen-key -n client.admin --set-uid=0 --cap mon ‘allow *‘ --cap osd ‘allow *‘ --cap mgr ‘allow *‘ --cap mds ‘allow *‘
添加client.admin的秘钥到/tmp/backup.mon.keyring文件中
[root@ceph5 ceph]# ceph-authtool /tmp/backup.mon.keyring --import-keyring /etc/ceph/backup.client.admin.keyring
[root@ceph5 ~]# monmaptool --create --add ceph5 172.25.250.14 --fsid 51dda18c-7545-4edb-8ba9-27330ead81a7 /tmp/monmap
[root@ceph5 ceph]# file /tmp/monmaptool
[root@ceph5 ceph]# monmaptool --print /tmp/monmaptool
创建monitor使用的目录
[root@ceph5 ~]# mkdir -p /var/lib/ceph/mon/backup-ceph5
设置文件相关的权限
[root@ceph5 ~]# chown ceph.ceph -R /var/lib/ceph /etc/ceph /tmp/backup.mon.keyring /tmp/monmap
[root@ceph5 ~]# sudo -u ceph ceph-mon --cluster backup --mkfs -i ceph5 --monmap /tmp/monmap --keyring /tmp/backup.mon.keyring

由于ceph默认crushmap策略是基于host的故障域，在三副本的情况下，由于只有一个host，这时创建存储池后，ceph状态会变为HEALTH_WARN，而且一直无法重平衡PG，故障表现为：
