Booting a Cluster on ceph1

Boot a Ceph container cluster on ceph1.

1. Boot a Ceph cluster.
   • Single node:

     1	cephadm bootstrap --mon-ip xxip --single-host-defaults --no-minimize-config

   • Multiple nodes:

     1	cephadm bootstrap --mon-ip xxip --cluster-network xxx --no-minimize-config

     

     xxx indicates the actual local IP address.

     --mon-ip specifies the IP address of the front-end network.

     --cluster-network specifies the IP address of the back-end network.

     

2. Copy the public key to other nodes (if multiple nodes are used).

   ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph2
   ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph3

3. Synchronize the local repository configuration to other nodes.

   scp /etc/containers/registries.conf ceph2:/etc/containers/
   scp /etc/containers/registries.conf ceph3:/etc/containers/

4. Enter a Ceph cluster container.

   1	cephadm shell

5. Add hosts. (Wait for 3 to 5 minutes after the following commands are executed.)

   1 2	ceph orch host add ceph2 ceph orch host add ceph3

6. Check whether the hosts are added.

   1	ceph orch host ls

   

7. Check the cluster status and ensure that the other two nodes are added to the cluster.
