前言:
很多朋友想学ceph,但是开始ceph部署就让初学者举步为艰,ceph部署时由于国外源的问题(具体大家应该懂得),下载和安装软件便会卡住,停止不前。即使配置搭建了国内源后,执行ceph-deploy install 时又跑去了国外的源下载,很是无语呀!!!这样导致我们停下了学习ceph的脚步,所以笔者就在这里编写了这篇文章,只要掌握了通过国内源找到并下载对应正确的ceph版本rpm包到本地,部署ceph简直小意思!
一、部署准备:
准备5台机器(linux系统为centos7.6版本),当然也可以至少3台机器并充当部署节点和客户端,可以与ceph节点共用:
1台部署节点(配一块硬盘,运行ceph-depoly)
3台ceph节点(配两块硬盘,第一块为系统盘并运行mon,第二块作为osd数据盘)
1台客户端(可以使用ceph提供的文件系统,块存储,对象存储)
(1)所有ceph集群节点(包括客户端)设置静态域名解析;

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.254.163 dlp
172.16.254.64 node1
172.16.254.65 node2
172.16.254.66 node3
172.16.254.63 controller
|
(2)所有集群节点(包括客户端)创建cent用户,并设置密码,后执行如下命令:
1
2
3
|
useradd cent && echo
"123"
| passwd --stdin cent
echo -e
'Defaults:cent !requiretty\ncent ALL = (root) NOPASSWD:ALL'
| tee /etc/sudoers.d/ceph
chmod 440 /etc/sudoers.d/ceph
|
(3)在部署节点切换为cent用户,设置无密钥登陆各节点包括客户端节点
1

ceph@dlp15:17:01~
#ssh-keygen
ceph@dlp15:17:01~
#ssh-copy-id con1
ceph@dlp15:17:01~
#ssh-copy-id con2
ceph@dlp15:17:01~
#ssh-copy-id con3
ceph@dlp15:17:01~
#ssh-copy-id controller
|
(4)在部署节点切换为cent用户,在cent用户家目录,设置如下文件:vi~/.ssh/config# create new ( define all nodes and users )

二、所有节点配置国内ceph源:
(1)all-node(包括客户端)在/etc/yum.repos.d/创建 ceph-yunwei.repo
1
2
3
4
5
|
[ceph-yunwei]
name=ceph-yunwei-install
baseurl=https:
//mirrors.aliyun.com/centos/7.6.1810/storage/x86_64/ceph-jewel/
enable=1
gpgcheck=0
|
或者也可以将如上内容添加到现有的 CentOS-Base.repo 中。
(2)到国内ceph源中
https://mirrors.aliyun.com/centos/7.6.1810/storage/x86_64/ceph-jewel/下载如下所需rpm包。注意:红色框中为ceph-deploy的rpm,只需要在部署节点安装,下载需要到
https://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/中找到最新对应的ceph-deploy-xxxxx.noarch.rpm 下载

(3)将下载好的rpm拷贝到所有节点,并安装。注意ceph-deploy-xxxxx.noarch.rpm 只有部署节点用到,其他节点不需要,部署节点也需要安装其余的rpm
(4)在部署节点(cent用户下执行):安装 ceph-deploy,
在root用户下,进入下载好的rpm包目录,执行:
1
|
yum localinstall -y ./*
|
(或者sudo yum install ceph-deploy)
创建ceph工作目录
1
|
mkdir ceph && cd ceph
|
注意:如遇到如下报错:
处理办法1:
可能不能安装成功,报如下问题:将python-distribute remove 再进行安装(或者 yum remove python-setuptools -y)
注意:如果不是安装上述方法添加的rpm,用的是网络源,每个节点必须yum install ceph ceph-radosgw -y
处理办法2:安装依赖包:python-distribute

(11)在/data/下面创建osd挂载目录:
1
2
3
4
|
mkdir /data/osd
chown -R ceph.ceph /data/
chmod 750 /data/osd/
ln -s /data/osd /
var
/lib/ceph
|
注意:准备前先将硬盘做文件系统 xfs,挂载到/var/lib/ceph/osd,并且注意属主和属主为ceph:
列出节点磁盘:ceph-deploy disk list node1
擦净节点磁盘:ceph-deploy disk zap node1:/dev/vdb1
(12)准备Object Storage Daemon:
1
|
ceph-deploy osd prepare node1:/
var
/lib/ceph/osd node2:/
var
/lib/ceph/osd node3:/
var
/lib/ceph/osd
|
(13)激活Object Storage Daemon:
1
|
ceph-deploy osd activate node1:/
var
/lib/ceph/osd node2:/
var
/lib/ceph/osd node3:/
var
/lib/ceph/osd
|
(14)在部署节点transfer config files
1
2
|
ceph-deploy admin dlp node1 node2 node3
sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
|
(15)在ceph集群中任意节点检测:
1
|
ceph -s
|
三、客户端设置:
(1)客户端也要有cent用户:
1
2
3
|
useradd cent && echo
"123"
| passwd --stdin cent
echo-e
'Defaults:cent !requiretty\ncent ALL = (root) NOPASSWD:ALL'
| tee /etc/sudoers.d/ceph
chmod440 /etc/sudoers.d/ceph
|
在部署节点执行,安装ceph客户端及设置:
1
2
|
ceph-deploy install controller
ceph-deploy admin controller
|
(2)客户端执行
1
|
sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
|
(3)客户端执行,块设备rdb配置:
1
2
3
4
5
6
7
|
创建rbd:rbd create disk01 --size 10G --image-feature layering
列示rbd:rbd ls -l
映射rbd的image map:sudo rbd map disk01
显示map:rbd showmapped
格式化disk01文件系统xfs:sudo mkfs.xfs /dev/rbd0
挂载硬盘:sudo mount /dev/rbd0 /mnt
验证是否挂着成功:df -hT
|
(4)File System配置:
在部署节点执行,选择一个node来创建MDS:
1
|
ceph-deploy mds create node1
|
以下操作在node1上执行:
1
|
sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
|
在MDS节点node1上创建 cephfs_data 和 cephfs_metadata 的 pool
1
2
|
ceph osd pool create cephfs_data 128
ceph osd pool create cephfs_metadata 128
|
开启pool:
1
|
ceph fs
new
cephfs cephfs_metadata cephfs_data
|
显示ceph fs:
1
2
|
ceph fs ls
ceph mds stat
|
以下操作在客户端执行,安装ceph-fuse:
1
|
yum -y install ceph-fuse
|
获取admin key:
1
2
|
sshcent@node1
"sudo ceph-authtool -p /etc/ceph/ceph.client.admin.keyring"
> admin.key
chmod600 admin.key
|
挂载ceph-fs:
1
2
|
mount-t ceph node1:6789:/ /mnt -o name=admin,secretfile=admin.key
df-hT
|
停止ceph-mds服务:
1
2
3
4
5
6
7
8
|
systemctl stop ceph-mds@node1
ceph mds fail 0
ceph fs rm cephfs --yes-i-really-mean-it
ceph osd lspools
显示结果:0 rbd,1 cephfs_data,2 cephfs_metadata,
ceph osd pool rm cephfs_metadata cephfs_metadata --yes-i-really-really-mean-it
|
四、删除环境:
1
2
3
4
|
ceph-deploy purge dlp node1 node2 node3 controller
ceph-deploy purgedata dlp node1 node2 node3 controller
ceph-deploy forgetkeys
rm -rf ceph*
