一、准备环境
1.修改hosts文件
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#Ceph
10.39.40.1 ceph-1
10.39.40.2 ceph-2
10.39.40.3 ceph-3
2.安装插件
#ntp时间同步，自行配置
yum install vim git ntpd
#安装ceph-deploy
yum install -yls https://download.ceph.com/rpm-kraken/el7/noarch/ceph-deploy-1.5.38-0.noarch.rpm
3.配置Ceph国内源
CentOS:
export CEPH_DEPLOY_REPO_URL=http://mirrors.163.com/ceph/rpm-jewel/el7
export CEPH_DEPLOY_GPG_URL=http://mirrors.163.com/ceph/keys/release.asc
二、部署集群
1.创建目录
#创建ceph目录
mkdir /etc/ceph
cd /etc/ceph
#部署一个默认名为ceph的新的ceph集群;他声称集群配置和keying文件
ceph-deploy new ceph-1
2.修改配置文件vim /etc/ceph/ceph.conf
[global]
fsid = xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
mon_initial_members = ceph-1,ceph-2,ceph-3
mon_host = 10.39.40.1,10.39.40.2,10.39.40.3
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
pubulic_network = 10.39.40.0/24
#使用ceph-deploy工具将ceph软件的二进制包安装到所有的节点上
ceph-deploy install --release emperor ceph-1 ceph-2 ceph-3
#分发配置文件
ceph-deploy --overwrite-conf config push ceph-2 ceph-3
#在ceph-node上创建你的第一个monitor;
ceph-deploy mon create-initial
#disk zap 命令会销毁磁盘中已存在的分区表和数据
ceph-deploy disk zap ceph-1:vdc ceph-2:vdc ceph-3:vdc
#欧舒丹create命令准备好磁盘，也就是说，它会擦除磁盘原有数据并新建文件系统，默认为xfs
ceph-deploy osd create ceph-1:vdc ceph-2:vdc ceph-3:vdc
#在ceph-2,ceph-3上创建systemonitor;
ceph mon create ceph-2
ceph mon create ceph-3
#添加磁盘与第一次添加磁盘一样
ceph-deploy disk zap ceph-1:vdd ceph-2:vdd ceph-3:vdd
ceph-deploy osd create ceph-1:vdd ceph-2:vdd ceph-3:vdd
