ceph手动部署
一、 节点规划
主机名 | IP地址 | 角色 |
---|---|---|
ceph01.example.com | 172.18.0.10/24 | mon、mgr、osd、mds、rgw |
ceph02.example.com | 172.18.0.20/24 | mon、mgr、osd、mds、rgw |
ceph03.example.com | 172.18.0.30/24 | mon、mgr、osd、mds、rgw |
操作系统版本: Rocky Linux release 8.8 (Green Obsidian)
二、 准备工作
以下操作所有主机都要操作
- 替换YUM源
sed -e ‘s|^mirrorlist=|#mirrorlist=|g’
-e ‘s|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.aliyun.com/rockylinux|g‘
-i.bak
/etc/yum.repos.d/Rocky-.repo
dnf makecache
- 关闭防火墙和SELINUX
systemctl disable –now firewalld.service
setenforce 0
vim /etc/sysconfig/selinux
- 配置时间同步
echo “server ntp.aliyun.com iburst” >> /etc/chronyd.conf
systemctl enable –now chronyd
chronyc sources
- 主机名与IP进行映射
vim /etc/hosts
172.18.0.10 ceph01.example.com ceph01
172.18.0.20 ceph02.example.com ceph02
172.18.0.30 ceph03.example.com ceph03
- 节点安装ceph软件包
yum install centos-release-ceph-pacific -y 此处使用P版 目前企业级存储使用的稳定版
yum install ceph -y
三、配置MON
- 生成集群UUID
uuidgen
eb6d6dab-6854-4663-ba7f-eadf2758e681
- 创建ceph.conf配置文件
vim /etc/ceph/ceph.conf
[global]
fsid=eb6d6dab-6854-4663-ba7f-eadf2758e681
mon_initial_members=ceph01,ceph02,ceph03
mon_host=172.18.0.10,172.18.0.20,172.18.0.30
public_network=172.18.0.0/24
auth_cluster_required=cephx
auth_service_required=cephx
auth_client_required=cephx
osd_pool_default_size=3
osd_pool_default_min_size=2
osd_pool_default_pg_num=128
osd_pool_default_pgp_num=128
storage_type=bluestore
osd_objectstore=bluestore
osd_mkfs_type=xfs
bluestore_block_size=5628755968
- 生成monitor keyring
ceph-authtool –create-keyring /tmp/ceph.mon.keyring –gen-key -n mon. –cap mon ‘allow ‘
- 生成admin管理员key
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 ‘
- 生成OSD引导key
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’
- 将admin和osd引导key导入到mon key中
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
- 生成monmap映射视图
monmaptool –create –add ceph01 172.18.0.10 –add ceph02 172.18.0.20 –add ceph03 172.18.0.30 –fsid eb6d6dab-6854-4663-ba7f-eadf2758e681 /tmp/monmap
- 拷贝文件到其他节点
scp /etc/ceph/ceph.conf root@ceph02:/etc/ceph/
scp /etc/ceph/ceph.conf root@ceph03:/etc/ceph/
scp /tmp/monmap root@ceph02:/tmp/
scp /tmp/monmap root@ceph03:/tmp/
scp /tmp/ceph.mon.keyring root@ceph02:/tmp/
scp /tmp/ceph.mon.keyring root@ceph03:/tmp/
scp /etc/ceph/ceph.client.admin.keyring root@ceph02:/etc/ceph/
scp /etc/ceph/ceph.client.admin.keyring root@ceph03:/etc/ceph/
- 从映射视图导入集群关系(在所有节点上操作)
sudo -u ceph mkdir /var/lib/ceph/mon/ceph-ceph01(ceph01改成不同的主机名)
ceph-mon –mkfs -i ceph01 –monmap /tmp/monmap –keyring /tmp/ceph.mon.keyring(ceph01改成不同的主机名)
chown ceph.ceph -R /var/lib/ceph
- 启动mon服务并查看集群状态(在所有节点上操作)
systemctl enable –now ceph-mon@ceph01.service (ceph01改成不同的主机名)
ceph -s 查看集群状态
问题1:3 monitors have not enabled msgr2
ceph mon enable-msgr2 ()
问题2:mons are allowing insecure global_id reclaim
ceph config set mon auth_allow_insecure_global_id_reclaim false(禁用不安全模式)
四、配置MGR
1-3以下所有节点均需要操作
- 创建mgr key存放目录
sudo -u ceph mkdir /var/lib/ceph/mgr/ceph-$(hostname -s)
- 生成mgr key
ceph auth get-or-create mgr. $(hostname -s) mon ‘allow profile mgr’ osd ‘allow ‘ mds ‘allow ‘ > /var/lib/ceph/mgr/ceph-$(hostname -s)/keyring
- 启动mgr服务
systemctl enable –now ceph-mgr@ceph01.service (ceph01在不同节点上换成不同主机名)
- 配置dashboard图形化控制台
4.0 安装dashboard模块并启用
yum install ceph-mgr-dashboard -y
4.1 生成自签名证书
openssl req -new -nodes -x509 -subj "/O=IT/CN=ceph-mgr-dashboard" -days 3650
-keyout dashboard.key -out dashboard.crt -extensions v3_ca
4.2 导入证书
ceph dashboard set-ssl-certificate -i dashboard.crt
ceph dashboard set-ssl-certificate-key -i dashboard.key
4.3 配置地址和端口
ceph config set mgr mgr/dashboard/server_addr 0.0.0.0
ceph config set mgr mgr/dashboard/ssl_server_port 8443
4.4 禁用rgw api校验自签名证书(如果启用rgw ssl则需要)
ceph dashboard set-rgw-api-ssl-verify false
4.5初始化 dashboard 用户
echo redhat123 > pass.txt
ceph dashboard ac-user-create admin administrator -i pass.txt
4.6 启用http关闭ssl
mgr-dashboard默认使用ssl进行访问,关闭ssl可以使用http
ceph config set mgr mgr/dashboard/ssl false
4.7 启用或禁用dashboard
ceph config module disable dashboard
ceph config module enable dashboard
五、配置OSD
- 拷贝OSD的密钥环(ceph01操作)
scp /var/lib/ceph/bootstrap-osd/ceph.keyring root@ceph02:/var/lib/ceph/bootstrap-osd/
scp /var/lib/ceph/bootstrap-osd/ceph.keyring root@ceph03:/var/lib/ceph/bootstrap-osd/
拷贝后修改文件的权限chown ceph.ceph /var/lib/ceph/bootstrap-osd/ceph.keyring
- 创建OSD
ceph-volume lvm create –data /dev/sdb –bluestore
说明:
–bluestore 不接时默认为bluestore后端驱动,使用–filestore则使用文件级filestore驱动,cephadm不支持管理后端驱动为filestore的OSD
上述过程可以拆分成两步:
准备OSD:ceph-volume lvm prepare –data /dev/sdb
激活OSD:ceph-volume lvm activate {ID} {FSID}
ceph-volume lvm list 查看OSD的ID
- 查看集群状态以及添加的OSD
ceph -s 查看集群状态是否ok
ceph osd ls
六、配置MDS
以下操作所有节点都要做
1. 创建mds key存放目录
sudo -u ceph mkdir /var/lib/ceph/mds/ceph-$(hostname -s)
-
生成mds keyring
ceph auth get-or-create mds.$(hostname -s) osd "allow rwx" mds "allow" mon "allow profile mds" > /var/lib/ceph/mds/ceph-$(hostname -s)/keyring
chown ceph.ceph -R /var/lib/ceph/mds/ceph-ceph02/keyring
-
启动mds 服务
systemctl start ceph-mds@ceph01.service
systemctl start ceph-mds@ceph02.service
systemctl start ceph-mds@ceph03.service
- 创建文件系统测试
ceph osd pool create fspool_meta 创建文件系统元数据池
ceph osd pool create fspool_data 创建文件系统数据池
ceph fs new fs01 fspool_meta fspool_data 创建fs01的文件系统
ceph fs status 查看文件系统的主从节点
ceph fs authorize fs01 client.wangwu / rw 创建文件系统使用用户王五并授权
mount -t ceph ceph01:/ /media/ -o name=wangwu,fs=fs01,secret=AQB3ryJl1Z2QMRAAH1C/qRaBGIKKBWET5lM1eg== 挂载测试
七、配置RGW
1.安装软件包(所有节点操作)
yum install ceph-radosgw -y
2.创建 rgw key(ceph01操作)
ceph auth get-or-create client.rgw.ceph01 osd ‘allow rwx’ mon ‘allow rwx’ >> /etc/ceph/ceph.client.radosgw.keyring
ceph auth get-or-create client.rgw.ceph02 osd ‘allow rwx’ mon ‘allow rwx’ >> /etc/ceph/ceph.client.radosgw.keyring
ceph auth get-or-create client.rgw.ceph03 osd ‘allow rwx’ mon ‘allow rwx’ >> /etc/ceph/ceph.client.radosgw.keyring
chown ceph:ceph /etc/ceph/ceph.client.radosgw.keyring
scp /etc/ceph/ceph.client.radosgw.keyring root@ceph02:/etc/ceph/
chown ceph:ceph /etc/ceph/ceph.client.radosgw.keyring (ceph02操作)
scp /etc/ceph/ceph.client.radosgw.keyring root@ceph03:/etc/ceph/
chown ceph:ceph /etc/ceph/ceph.client.radosgw.keyring (ceph03操作)
4.编辑配置文件(ceph01操作)
vim /etc/ceph.conf 新增rgw配置
[client.rgw.ceph01]
host=ceph01
keyring=/etc/ceph/ceph.client.radosgw.keyring
log file=/var/log/radosgw/client.radosgw.gateway.log
rgw frontends = civetweb port=172.18.0.10:8080
[client.rgw.ceph02]
host=ceph02
keyring=/etc/ceph/ceph.client.radosgw.keyring
log file=/var/log/radosgw/client.radosgw.gateway.log
rgw frontends = civetweb port=172.18.0.20:8080
[client.rgw.ceph03]
host=ceph03
keyring=/etc/ceph/ceph.client.radosgw.keyring
log file=/var/log/radosgw/client.radosgw.gateway.log
rgw frontends = civetweb port=172.18.0.30:8080
scp /etc/ceph/ceph.conf root@ceph02:/etc/ceph/
scp /etc/ceph/ceph.conf root@ceph03:/etc/ceph/
- 创建日志目录(所有节点操作)
sudo -u ceph mkdir /var/log/radosgw/
- 启动RGW服务(对应节点操作)
systemctl enable –now ceph-radosgw@rgw.ceph01.service
systemctl enable –now ceph-radosgw@rgw.ceph02.service
systemctl enable –now ceph-radosgw@rgw.ceph03.service
服务启动后rgw将自动创建以下存储池
.rgw.root #包含 realm(领域信息),比如 zone 和 zonegroup
default.rgw.log #存储日志信息,用于记录各种 log 信息
default.rgw.control #系统控制池,在有数据更新时,通知其它 RGW 更新缓存
default.rgw.meta #元数据存储池,通过不同的名称空间分别存储不同的 rados 对象
- 创建s3用户测试
radosgw-admin user create –uid=user1 –access-key=123 –secret=456 –email user1@example.com –display-name user1
-
s3对象存储测试(任意选择一个节点测试)
7.1 安装s3工具
yum install epel-release -y 使用epel源
yum install aws -y 安装s3客户端工具
7.2 配置s3访问凭据
aws configure –profile=ceph 凭据名为ceph
输入ak和sk
7.3 创建存储桶
aws –profile=ceph –endpoint-url=http://172.18.0.10:8080 s3 mb s3://bucket1
7.4 上传文件到桶
aws –profile=ceph –endpoint-url http://172.18.0.10:8080 s3 cp /etc/passwd s3://bucket1/passwd
