一、环境要求：
硬件环境：
- 单机（虚拟机）
- CPU 8 cores
- MEM 32G
- DISK 3 x 100G
软件环境：
- Centos7 x64
- 数据盘 /dev/sdb1 /data1 xfs
- 数据盘 /dev/sdc1 /data2 xfs
- 系统接入互联网
CEPH版本
- ceph-deploy v1.5.37
- ceph version 10.2.7
二、系统环境配置
网络：vi /etc/sysconfig/network-scripts/ifcfg-ens33BOOTPROTO=staticONBOOT=yesIPADDR=192.168.3.125DNS1=192.168.3.1GATEWAY=192.168.3.1
HostName：sed -i '/HOSTNAME/d' /etc/sysconfig/networkecho "HOSTNAME=cydb" >> /etc/sysconfig/networkcat /etc/sysconfig/networkecho "192.168.3.125 cydb" >> /etc/hostscat /etc/hostshostname cydbhostname -f
SSH：ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsassh-copy-id root@cydb
Firewall：systemctl stop firewalld.servicesystemctl disable firewalld.servicesystemctl status firewalld.service
SELinux：setenforce 0sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/configcat /etc/selinux/configrebootsestatus
三、Object文件系统
ceph安装源：
yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[ceph-noarch]
name=Ceph noarch packages
baseurl=https://download.ceph.com/rpm-jewel/el7/noarch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
cat /etc/yum.repos.d/ceph.repo
yum clean all
yum makecache
四、安装ceph-deploy：
yum install -y ceph-deploy
ceph-deploy --help
五、部署cluster：
mkdir /opt/ceph-cluster
cd /opt/ceph-cluster
ceph-deploy new cydb
echo "osd crush chooseleaf type = 0" >> ceph.conf
echo "osd pool default size = 1" >> ceph.conf
echo "osd journal size = 100" >> ceph.conf
cat ceph.conf
六、安装ceph包：yum remove -y ceph-release # 如果安装失败，则执行ceph-deploy install cydbceph --version
七、部署monitor：ceph-deploy mon create-initialceph mon statceph mon dump
八、添加OSDs：
首先需要将磁盘格式化成xfs文件系统，然后创建osd。
ceph-deploy osd create --zap-disk --fs-type xfs centos7-dev:/dev/sdd
chown ceph:ceph /data1chown ceph:ceph /data2ceph-deploy osd prepare cydb:/data1ceph-deploy osd prepare cydb:/data2ceph-deploy osd activate cydb:/data1ceph-deploy osd activate cydb:/data2ceph osd statceph osd treeceph osd dump
