关闭selinux 及防火墙
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
systemctl disable firewalld
systemctl stop firewalld更改yum源为阿里云
sed -e 's|^mirrorlist=|#mirrorlist=|g' \

/etc/yum.repos.d/Rocky-*.repo
dnf makecache安装软件包（可选）
yum install -y wget bash-completion net-tools vim安装epel源及ceph源
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*

dnf makecache在/etc/hosts 填加如下行
192.168.3.146 node1
192.168.3.147 node2
192.168.3.148 node3
192.168.8.146 node1
192.168.8.147 node2
192.168.8.148 node3
配置时间同步
dnf install -y chrony
systemctl enable --now chronyd
chronyc sources -v
配置免密登录（可选）
ssh-keygen
ssh-copy-id node1
ssh-copy-id node2
ssh-copy-id node3
for host in node1 node2 node3;do ssh root@$host date;done
安装docker
dnf -y install docker安装cephadm
dnf -y install cephadm
cephadm -h
初始化集群
cephadm bootstrap --mon-ip 192.168.3.146 --cluster-network 192.168.8.0/24
集群初如化成功
sudo /usr/sbin/cephadm shell --fsid fc0ce88c-2f6d-11ed-b23c-000c293e2d96 -c /etc/ceph/ceph.conf -k /etc/ceph/ceph.client.admin.keyring
ceph -s
ceph version
也可退出容器执行
cephadm shell ceph -s
三台服务器安装 ceph-common
dnf -y install ceph-common安装完毕后，退出容器可执行命令ceph -s
key 文件：
cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQDH2RljgCNXBRAAKaOpbXMB6hD9G3uVC9KRYQ==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"
docker ps
加入node2 node3
ssh-copy-id -f -i /etc/ceph/ceph.pub node2
ssh-copy-id -f -i /etc/ceph/ceph.pub node3
ceph orch host ls
ceph orch host add node2 192.168.3.147
ceph orch host add node3 192.168.3.148
ceph orch host ls 
填加标签
ceph orch host label add node2 _admin
ceph orch host label add node3 _admin
mon mgr填加节点后会自动部署
web登陆查看
填加OSD
ceph orch daemon add osd node1:/dev/sdb,/dev/sdc
ceph orch daemon add osd node2:/dev/sdb,/dev/sdc
ceph orch daemon add osd node3:/dev/sdb,/dev/sdc检查集群状态
ceph -s
ceph health
