Chapter 8. Basic Red Hat Ceph Storage client setup

Procedure

1. On the node where you want to set up the files, create a directory ceph in the /etc folder:

   Example

   [root@host01 ~]# mkdir /etc/ceph/

2. Navigate to /etc/ceph directory:

   Example

   [root@host01 ~]# cd /etc/ceph/

3. Generate the configuration file in the ceph directory:

   Example

   [root@host01 ceph]# ceph config generate-minimal-conf
   
   # minimal ceph.conf for 417b1d7a-a0e6-11eb-b940-001a4a000740
   [global]
   	fsid = 417b1d7a-a0e6-11eb-b940-001a4a000740
   	mon_host = [v2:10.74.249.41:3300/0,v1:10.74.249.41:6789/0]

   The contents of this file should be installed in /etc/ceph/ceph.conf path. You can use this configuration file to reach the Ceph monitors.

Procedure

1. On the node where you want to set up the keyring, create a directory ceph in the /etc folder:

   Example

   [root@host01 ~]# mkdir /etc/ceph/

2. Navigate to /etc/ceph directory in the ceph directory:

   Example

   [root@host01 ~]# cd /etc/ceph/

3. Generate the keyring for the client:

   Syntax

   ceph auth get-or-create client.CLIENT_NAME -o /etc/ceph/NAME_OF_THE_FILE

   Example

   [root@host01 ceph]# ceph auth get-or-create client.fs -o /etc/ceph/ceph.keyring

4. Verify the output in the ceph.keyring file:

   Example

   [root@host01 ceph]# cat ceph.keyring
   
   [client.fs]
   	key = AQAvoH5gkUCsExAATz3xCBLd4n6B6jRv+Z7CVQ==

   The resulting output should be put into a keyring file, for example /etc/ceph/ceph.keyring.
