Ceph集群搭建2025（squid版）

squid版本维护年限

apt install -y cephadmecho >> "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

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-------

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

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 _adminceph orch host label add ceph-2 _adminceph orch host label add ceph-3 _admin

调整MON(3),MGR(2个)，因为只有3个节点

 ceph orch apply mon 3ceph orch apply mgr 2

mon                                         3/3  3m ago     22m  count:3    
node-exporter              ?:9100           3/3  3m ago     21m  count:3    
osd.all-available-devices                     3  3m ago     20m  *          
prometheus                 ?:9095           1/1  3m ago     40m  count:1    

最后自动添加所有osd级初始化磁盘

ceph orch apply osd --all-available-devices
