【ceph运维】含秘钥nautilus版三节点ceph集群手动部署
一、基础配置
集群拓扑图：
三台环境为centos7，以下配置需要在每台机器上执行。
| 名称 | 主机IP | 说明 |
| node01 | 192.168.19.101 | mon、mds、rgw、mgr、osd |
| node02 | 192.168.19.102 | mon、mds、rgw、mgr、osd |
| node03 | 192.168.19.103 | mon、mds、rgw、mgr、osd |
1. 配置host 解析：
cat >> /etc/hosts <<EOF
192.168.19.101 node1
192.168.19.102 node2
192.168.19.103 node3
EOF2. 关闭防火墙和selinux：
systemctl stop firewalld && systemctl disable firewalld
setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config3. 分别在三个节点设置主机名：
hostnamectl set-hostname node1
hostnamectl set-hostname node2
hostnamectl set-hostname node34. 配置主机时间同步：
systemctl restart chronyd.service && systemctl enable chronyd.service5. 设置/etc/ceph/ceph.conf配置项：
auth client required = cephx
auth cluster required = cephx
auth service required = cephx二、部署mon
1. 为集群生成一个唯一的fsid：
uuidgen2. 为此集群创建密钥环 keyring 并生成监视器密钥 ：
sudo ceph-authtool --create-keyring /tmp/ceph.mon.keyring --gen-key -n mon. --cap mon 'allow *'输出：
[root@node01 ~]# cat /tmp/ceph.mon.keyring
[mon.]
key = AQBQYt9kQr8SDBAA05KJPJ7wj/cojuhu6rvVWQ==
caps mon = "allow *"3. 生成管理员密钥环 keyring，生成 client.admin 用户并加入密钥环：
sudo 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 *'输出：
[root@node01 ~]# cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQB3Yt9kcV0CHxAA2ljATohTAe0u75zEtyTgLA==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"4. 生成引导 osd 密钥，生成用户并将用户添加到 client.bootstrap-osd keyring ：
sudo 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'输出：
[root@node01 ~]# cat /var/lib/ceph/bootstrap-osd/ceph.keyring
[client.bootstrap-osd]
key = AQCmYt9kmTFMBBAAW8+Rwnv3iuRU6f2qVo5kXw==
caps mgr = "allow r"
caps mon = "profile bootstrap-osd"5. 将生成的keyring 导入到 ceph.mon.keyring：
sudo ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
sudo ceph-authtool /tmp/ceph.mon.keyring --import-keyring /var/lib/ceph/bootstrap-osd/ceph.keyring输出：
[root@node01 ~]# sudo ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring
importing contents of /etc/ceph/ceph.client.admin.keyring into /tmp/ceph.mon.keyring
[root@node01 ~]# cat /tmp/ceph.mon.keyring
[mon.]
key = AQBQYt9kQr8SDBAA05KJPJ7wj/cojuhu6rvVWQ==
caps mon = "allow *"
[client.admin]
key = AQB3Yt9kcV0CHxAA2ljATohTAe0u75zEtyTgLA==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"
[root@node01 ~]# sudo ceph-authtool /tmp/ceph.mon.keyring --import-keyring /var/lib/ceph/bootstrap-osd/ceph.keyring
importing contents of /var/lib/ceph/bootstrap-osd/ceph.keyring into /tmp/ceph.mon.keyring
[root@node01 ~]# cat /tmp/ceph.mon.keyring
[mon.]
key = AQBQYt9kQr8SDBAA05KJPJ7wj/cojuhu6rvVWQ==
caps mon = "allow *"
[client.admin]
key = AQB3Yt9kcV0CHxAA2ljATohTAe0u75zEtyTgLA==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"
[client.bootstrap-osd]
key = AQCmYt9kmTFMBBAAW8+Rwnv3iuRU6f2qVo5kXw==
caps mgr = "allow r"
caps mon = "profile bootstrap-osd"6. 更改 ceph.mon.keyring 的所有者：
sudo chown ceph:ceph /tmp/ceph.mon.keyring7. 使用主机名、主机 IP 地址和 FSID 生成monitor映射，保存在 文件 /tmp/monmap中：
monmaptool --create --addv node01 [v2:192.168.19.101:3300,v1:192.168.19.101:6789] --fsid 33af1a28-8923-4d40-af06-90c376ed74b0 /tmp/monmap8. 在mon主机上创建默认数据目录，目录名是{cluster-name}-{hostname}格式 :
sudo -u ceph mkdir /var/lib/ceph/mon/ceph-node019. 在node1节点对monitor进行初始化：
sudo -u ceph ceph-mon --mkfs -i node01 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring10. 将配置文件拷贝到其他节点：
scp /etc/ceph/ceph.conf node2:/etc/ceph/ceph.conf
scp /etc/ceph/ceph.conf node3:/etc/ceph/ceph.conf11. 将mon keyring,mon map及admin keyring拷贝到其他节点
scp /tmp/ceph.mon.keyring node2:/tmp/ceph.mon.keyring
scp /etc/ceph/ceph.client.admin.keyring node2:/etc/ceph/ceph.client.admin.keyring
scp /tmp/monmap node2:/tmp/monmap
scp /tmp/ceph.mon.keyring node3:/tmp/ceph.mon.keyring
scp /etc/ceph/ceph.client.admin.keyring node3:/etc/ceph/ceph.client.admin.keyring
scp /tmp/monmap node3:/tmp/monmap12. 在node2、node3上添加monitor，分别在这两个节点创建数据目录：
sudo -u mkdir /var/lib/ceph/mon/ceph-`hostname -s`即：
sudo -u mkdir /var/lib/ceph/mon/ceph-node02
sudo -u mkdir /var/lib/ceph/mon/ceph-node0313. 分别在这两个节点对monitor进行初始化：
sudo -u ceph-mon --mkfs -i `hostname -s` --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring即:
sudo -u ceph-mon --mkfs -i node02 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring
sudo -u ceph-mon --mkfs -i node03 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring14. 分别在三个节点启动ceph-mon服务：
systemctl start ceph-mon@`hostname -s`
systemctl enable ceph-mon@`hostname -s`启动失败可以尝试：
ceph-mon -i node01 -c /etc/ceph/ceph.conf --cluster ceph三、部署osd
执行命令如下：
ceph-volume lvm create --bluestore --data /dev/sdx --block.wal /dev/nsdy --block.db /dev/sdzceph-volume lvm create --bluestore --data /dev/sdx --block.db /dev/sdyceph-volume lvm create --bluestore --data /dev/sdx输出：

--> ceph-volume lvm activate successful for osd ID: 2
--> ceph-volume lvm create successful for: /dev/sdd注意：部署OSD需要文件/var/lib/ceph/bootstrap-osd/ceph.keyring, 将node01的该文件拷贝到node02、node03，在node02、node03执行命令如下：
scp root@192.168.19.101:/var/lib/ceph/bootstrap-osd/ceph.keyring /var/lib/ceph/bootstrap-osd/
清除lvm格式的osd:
// 逻辑卷
ceph-volume lvm zap {vg name/lv name}
// 块设备
ceph-volume lvm zap /dev/sdc1摧毁osd:
ceph-volume lvm zap /dev/sdc --destroy逻辑卷无法删除:
dmsetup remove {lv name}四、部署mgr
1. mgr节点执行：
sudo -u ceph mkdir /var/lib/ceph/mgr/ceph-`hostname -s`2. 创建身份验证密钥:
ceph auth get-or-create mgr.`hostname -s` mon 'allow profile mgr' osd 'allow *' mds 'allow *' > /var/lib/ceph/mgr/ceph-`hostname -s`/keyring输出：
[root@node01 ~]# ceph auth get-or-create mgr.`hostname -s` mon 'allow profile mgr' osd 'allow *' mds 'allow *' > /var/lib/ceph/mgr/ceph-`hostname -s`/keyring
[root@node01 ~]# cat /var/lib/ceph/mgr/ceph-`hostname -s`/keyring
[mgr.node01]
key = AQCdZd9kPTGvFBAAArWhRWZqpNgVKgkQoYjtcA==3. 启动mgr：
systemctl start ceph-mgr@node01
systemctl enable ceph-mgr@node01五、部署mds
1. 创建mds数据目录:
sudo -u ceph mkdir -p /var/lib/ceph/mds/ceph-`hostname -s`2. 创建keyting
ceph-authtool --create-keyring /var/lib/ceph/mds/ceph-`hostname -s`/keyring --gen-key -n mds.`hostname -s`输出：
[root@node01 ~]# ceph-authtool --create-keyring /var/lib/ceph/mds/ceph-node01/keyring --gen-key -n mds.node01
creating /var/lib/ceph/mds/ceph-node01/keyring
[root@node01 ~]# cat /var/lib/ceph/mds/ceph-node01/keyring
[mds.node01]
key = AQCTZt9kycWODhAA/0jjsASGYrQgnFmq36+qbQ==3. 导入keyring并设置权限：
ceph auth add mds.`hostname -s` osd "allow rwx" mds "allow" mon "allow profile mds" -i /var/lib/ceph/mds/ceph-node01/keyringchown ceph:ceph /var/lib/ceph/mds/ceph-`hostname -s`/keyring启动mds：
systemctl start ceph-mds@node01 && systemctl enable ceph-mds@ndoe014. cephfs 需要两个pool池，cephfs_data 和 cephfs_metadata，分别存储文件数据和文件元数据
创造数据 pool
ceph osd pool create cephfs_data 4创造元数据pool
ceph osd pool create cephfs_metadata 4启动文件系统：# 元数据池在前，数据池在后
ceph fs new cephfs cephfs_metadata cephfs_data 增加数据池：
ceph fs add_data_pool cephfs cephfs_data02fuse挂载文件系统
#挂载目录 "/test"
ceph-fuse -n client.admin -r / /test六、部署rgw
1. 创建keyring：
ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
chown ceph:ceph /etc/ceph/ceph.client.radosgw.keyring输出：
[root@node01 ~]# ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring
creating /etc/ceph/ceph.client.radosgw.keyring
[root@node01 ~]# cat /etc/ceph/ceph.client.radosgw.keyring
[root@node01 ~]#2. 生成ceph-radosgw服务对应的用户和key：
ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.rgw.node01 --gen-key输出：
[root@node01 ~]# ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.rgw.node01 --gen-key
[root@node01 ~]# cat /etc/ceph/ceph.client.radosgw.keyring
[client.rgw.node01]
key = AQA+aN9kW/wEHBAAWu1bMUojV9Ala6Hd+LYdEw==3. 添加用户访问权限：
ceph-authtool -n client.rgw.node01 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring输出：
[root@node01 ~]# ceph-authtool -n client.rgw.node01 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring
[root@node01 ~]# cat /etc/ceph/ceph.client.radosgw.keyring
[client.rgw.node01]
key = AQA+aN9kW/wEHBAAWu1bMUojV9Ala6Hd+LYdEw==
caps mon = "allow rwx"
caps osd = "allow rwx4. 将keyring导入集群中：
ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.rgw.node01 -i /etc/ceph/ceph.client.radosgw.keyring5. 编辑配置文件：
[client.rgw.node01]
host = node01
keyring = /etc/ceph/ceph.client.radosgw.keyring #重点
log file = /var/log/ceph/ceph-rgw-node01.log
rgw frontends = civetweb port=8080 num_threads=10000
rgw thread pool size = 512
rgw_s3_auth_use_rados = true
rgw_s3_auth_use_keystone = false
rgw_s3_auth_aws4_force_boto2_compat = false
rgw_s3_auth_use_ldap = false
rgw_s3_success_create_obj_status = 0
rgw_relaxed_s3_bucket_names = false6. 启动rgw服务：
systemctl start ceph-radosgw@rgw.node01 && systemctl enable ceph-radosgw@rgw.node01
