squid版本维护年限
复制代码
apt install -y cephadm
echo >> "deb http://mirrors.163.com/ceph/debian-squid/ bookworm main"
echo >> "deb-src http://mirrors.163.com/ceph/debian-squid/ bookworm main"
#安装源
cephadm install
#开始初始化一个最小的集群
cephadm bootstrap --mon-ip 172.16.8.71
3 拷贝公钥其他节点
复制代码
ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.8.72
ssh-copy-id -f -i /etc/ceph/ceph.pub root@172.16.8.73
---------其他节点安装cephadm-------
复制代码
apt install cephadm -y
# cephadm install
Installing packages ['cephadm']...
再回到安装节点添加节点。将自己也添加进去
复制代码
ceph orch host add ceph-1 172.16.8.71
ceph orch host add ceph-2 172.16.8.72
ceph orch host add ceph-3 172.16.8.73
##遵循官网的意见打标签
ceph orch host label add ceph-1 _admin
ceph orch host label add ceph-2 _admin
ceph orch host label add ceph-3 _admin
调整MON(3),MGR(2个)，因为只有3个节点
复制代码
ceph orch apply mon 3
ceph orch apply mgr 2

最后自动添加所有osd级初始化磁盘
复制代码
ceph orch apply osd --all-available-devices
