\`\`\`  
ceph -s  
mon:管理  
osd:对象存储设备  
yum install ceph ceph-radosgw -y  
ceph-deploy mgr create ceph\_node1  
\#1.先把disk清空  
ceph-deploy disk zap ceph\_node1 /dev/vdb  
ceph-deploy disk zap ceph\_node2 /dev/vdb  
ceph-deploy disk zap ceph\_node3 /dev/vdb  
\#2.加入到ceph  
ceph-deploy osd create --data /dev/vdb ceph1  
ceph-deploy osd create --data /dev/vdb ceph2  
ceph-deploy osd create --data /dev/vdb ceph3

(1)关闭防火墙  
systemctl stop firewalld  
systemctl disable firewalld

setenforce 0  
vim /etc/selinux/config  
selinux=disabled

yum install ntp ntpdate ntp-doc  
先ntpdate检查能否和以上ntp服务器通信。  
ntpdate -q time1.aliyun.com

vim /etc/ntp.conf  
server time1.aliyun.com  
server time2.aliyun.com  
server time3.aliyun.com  
server time4.aliyun.com  
server time5.aliyun.com  
server time6.aliyun.com  
server time7.aliyun.com

vim /etc/sysconfig/ntpd  
SYNC\_HWCLOCK=yes  
systemctl start ntpd  
systemctl enable ntpd

vim /etc/ntp.conf  
server 192.168.1.104 iburst  
systemctl start ntpd  
systemctl enable ntpd  
  
去官网查看ceph的yum源

yum clean all && yum makecache \#缓存yum源

yum -y install python-setuptools ceph-deploy ceph-common

cd /etc/ceph  
ceph-deploy new --public-network 192.168.1.0/24 ceph1

yum install ceph ceph-mon ceph-mgr ceph-radosgw ceph-mds -y  
==========以上每个节点都要运行=========  
admin节点上  
ceph-deploy mon create-initial  
ceph -s \#查看状态  
ceph-deploy admin ceph2 ceph3  
\#部署mgr  
ceph-deploy mgr create ceph1  
ceph-deploy osd create ceph1 --data /dev/sdb  
ceph-deploy osd create ceph2 --data /dev/sdb  
ceph-deploy osd create ceph3 --data /dev/sdb

ceph osd tree  
===========集群部署成功====================  
ceph-deploy mon add ceph2 --address 192.168.1.6  
ceph-deploy mon add ceph3 --address 192.168.1.7

ceph quorum\_status --format json-pretty  
ceph-deploy mgr create ceph2 ceph3

(2)官网安装地址  
https://docs.ceph.com/en/latest/install/install-storage-cluster/

ceph mgr module enable dashboard  
sudo ceph config-key set mgr/dashboard/node1/server\_addr 192.168.153.136  
web浏览器地址：192.168.153.136:7000

\#查看pool列表  
ceph osd lspool  
\#创建一个pool，名字ceph-demo，pg\_num=128，pgp\_num=128  
ceph osd pool create ceph-demo 128 128  
\#查看pg\_num  
ceph osd pool get ceph-demo pg\_num  
\#查看副本  
ceph osd pool get ceph-demo size  
\#设置副本2  
ceph osd pool set ceph-demo size 2  
\#crush\_rule算法  
ceph osd pool get ceph-demo crush\_rule  
\#  
ceph-deploy disk zap ceph1 /dev/sdb  
\#创建osd  
ceph-deploy osd create --data /dev/sdb ceph1  
\#关闭rebalance  
ceph osd set norebalance  
\#关闭nobackfill  
ceph osd set nobackfill
