NTP服务配置
NTP客户端配置
# vim /etc/ntp.conf
server 92.0.0.250
### 手动同步下时间
# ntpdate -u 92.0.0.250
### 启动服务
# systemctl start ntpd
# systemctl enable ntpd
### 检查同步
# ntpq -p
监控节点配置(方式一)
以下指令在anode节点执行
为CEPH集群生成UUID
# uuidgen
cb9321ef-c7b4-48f7-a1bf-5c75deede6ee
# tee /etc/ceph/ceph.conf << EOF
[global]
fsid = cb9321ef-c7b4-48f7-a1bf-5c75deede6ee
[mon.anode]
host = anode
mon addr = 92.0.0.11:6789
EOF
创建集群密钥环以及监视器密钥
# ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon ‘allow *‘
创建管理员密钥环,生成client.admin用户,然后添加用户到环上
# 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 *‘ --cap mgr ‘allow *‘
创建一个bootstrap-osd密钥环,生成client.bootstrap-osd用户,然后添加用户到环上
# ceph-authtool --create-keyring /var/lib/ceph/bootstrap-osd/ceph.keyring --gen-key -n client.bootstrap-osd --cap mon ‘profile bootstrap-osd‘
将生成的密钥添加到ceph.mon.keyring
# 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
创建监视器映射
# monmaptool --create --add anode 92.0.0.11 --fsid cb9321ef-c7b4-48f7-a1bf-5c75deede6ee /tmp/monmap
创建默认数据目录
# mkdir -p /var/lib/ceph/mon/ceph-anode
使用监视器映射和密钥环填充监视器服务
# ceph-mon --mkfs -i anode --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
更新配置文件
# tee /etc/ceph/ceph.conf << EOF
[global]
fsid = cb9321ef-c7b4-48f7-a1bf-5c75deede6ee
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = 1024
osd pool default size = 2
osd pool default min size = 1
osd pool default pg num = 128
osd pool default pgp num = 128
osd crush chooseleaf type = 1
[mon.anode]
host = anode
mon addr = 92.0.0.11:6789
EOF
标记监视器服务就绪
# touch /var/lib/ceph/mon/ceph-anode/done
启动监视器服务
### 有两种方式启动服务
### 方式一:修改数据目录权限
# chown -R ceph:ceph /var/lib/ceph
### 方式二:修改服务启动脚本
# vim /usr/lib/systemd/system/[email protected]
ExecStart=/usr/bin/ceph-mon -f --cluster ${CLUSTER} --id %i --setuser root --setgroup root
# systemctl daemon-reload
### 启动服务
# systemctl start [email protected]
# systemctl enable [email protected]
### 检测服务
# ceph -s
services:
mon: 1 daemons, quorum anode
mgr: no daemons active
osd: 0 osds: 0 up, 0 in
添加监控节点
以下指令在bnode节点执行
拷贝配置文件和客户端密钥
# scp [email protected]:/etc/ceph/ceph.conf /etc/ceph/
# scp [email protected]:/etc/ceph/ceph.client.admin.keyring /etc/ceph/
获取监控集群密钥环
# ceph auth get mon. -o /tmp/ceph.mon.keyring
获取监控集群映射文件
# ceph mon getmap -o /tmp/monmap
使用监视器映射和密钥环填充新的监视器服务
# ceph-mon --mkfs -i bnode --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
修改配置文件
### 配置文件的mon.anode是让你在没有配置bnode的时候让ceph mon命令知道怎么去连接ceph monitor集群(删除后会发现命令报错),在配置好bnode后,可以删除anode的配置也可以不删除,后面配置cnode的时候可以使用bnode的配置也可以使用anode的配置
# vim /etc/ceph/ceph.conf
[global]
fsid = cb9321ef-c7b4-48f7-a1bf-5c75deede6ee
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
osd journal size = 1024
osd pool default size = 2
osd pool default min size = 1
osd pool default pg num = 128
osd pool default pgp num = 128
osd crush chooseleaf type = 1
[mon.bnode]
host = bnode
mon addr = 92.0.0.12:6789
标记监视器服务就绪
# touch /var/lib/ceph/mon/ceph-bnode/done
启动监视器服务
# chown -R ceph:ceph /var/lib/ceph
### 启动服务
# systemctl start [email protected]
# systemctl enable [email protected]
### 检测服务
# ceph -s
services:
mon: 2 daemons, quorum anode,bnode
mgr: no daemons active
osd: 0 osds: 0 up, 0 in
同理添加cnode节点(配置文件可以拷贝anode节点的也可以拷贝bnode节点的)
# ceph -s
services:
mon: 3 daemons, quorum anode,bnode,cnode
mgr: no daemons active
osd: 0 osds: 0 up, 0 in
配置管理服务
以下指令在anode节点执行
创建密钥文件
# name="kolla"
# mkdir -p /var/lib/ceph/mgr/ceph-$name
# ceph auth get-or-create mgr.$name mon ‘allow profile mgr‘ osd ‘allow *‘ mds ‘allow *‘ -o /var/lib/ceph/mgr/ceph-$name/keyring
启动服务
# chown -R ceph:ceph /var/lib/ceph
# systemctl start [email protected]$name
# systemctl status [email protected]$name
# systemctl enable [email protected]$name
查询服务
# ceph -s
services:
mon: 3 daemons, quorum anode,bnode,cnode
mgr: kolla(active)
osd: 2 osds: 2 up, 2 in
同理配置好bnode和cnode节点
# ceph -s
services:
mon: 3 daemons, quorum anode,bnode,cnode

为OSD生成UUID
# UUID=$(uuidgen)
为OSD创建cephx密钥
# OSD_SECRET=$(ceph-authtool --gen-print-key)

# mkfs.xfs /dev/vdb
# mount /dev/vdb /var/lib/ceph/osd/ceph-$ID
修改fstab配置
### 在配置文件末尾添加
# vim /etc/fstab
/dev/vdb /var/lib/ceph/osd/ceph-1 xfs defaults 0 0
创建OSD密钥文件
# ceph-authtool --create-keyring /var/lib/ceph/osd/ceph-$ID/keyring --name osd.$ID --add-key $OSD_SECRET
初始化OSD数据目录
# ceph-osd -i $ID --mkfs --osd-uuid $UUID
启动服务
# chown -R ceph:ceph /var/lib/ceph/osd/ceph-$ID
# systemctl enable [email protected]$ID
# systemctl start [email protected]$ID

导入密钥环并设置权限
# ceph auth add mds.anode osd "allow rwx" mds "allow" mon "allow profile mds" -i /var/lib/ceph/mds/ceph-anode/keyring
修改配置文件
# vim /etc/ceph/ceph.conf
[global]
