Ubuntu 14.04 Standalone Installation CEPH

1, modify the/etc/hosts, so that the host name corresponding to the IP address of the machine (if you choose a loopback address 127.0.0.1 seemingly cannot parse the domain name). Note: The following host name is monster, the reader needs to change it to its own hostname

10.10.105.78    monster127.0.0.1       localhost

2. Create a directory Ceph and enter

3, prepare two block devices (can be hard disk or LVM volume), here we use LVM

   DD If=/dev/zero of=ceph-volumes.img bs=1m count=8192 oflag=direct   sgdisk-g--clear ceph-volumes.img   sudo Vgcreate ceph-volumes $ (sudo losetup--show-f ceph-volumes.img)   sudo lvcreate-l2g-nceph0 ceph-volumes   sudo lvc REATE-L2G-NCEPH1 ceph-volumes   sudo mkfs.xfs-f/dev/ceph-volumes/ceph0   sudo mkfs.xfs-f/dev/ceph-volumes/ CEPH1   mkdir-p/srv/ceph/{osd0,osd1,mon0,mds0}   sudo mount/dev/ceph-volumes/ceph0/srv/ceph/osd0   sudo Mount/dev/ceph-volumes/ceph1/srv/ceph/osd1

Based on the above command, we created two virtual disks ceph0 and CEPH1 and mounted them in the/SRV/CEPH/OSD0 and/SRV/CEPH/OSD1 directories respectively.

4, Installation Ceph-deploy

sudo apt-get install Ceph-deploy

5. Create a working directory, enter and create a cluster

   mkdir ceph-cluster   cd ceph-cluster   ceph-deploy new  Monster//Create a fresh cluster and write cluster.conf and keyring, etc.

Because we are working on a single node, we need to modify the configuration file

echo "OSD Crush Chooseleaf type = 0" >> Ceph.confecho "OSD Pool Default size = 1" >> Ceph.confecho "OSD Journa L size = ">> ceph.conf

6. Installing the Ceph Base library (Ceph,ceph-common, Ceph-fs-common, Ceph-mds)

Ceph-deploy Gatherkeys Monster

But I have a problem with the way I install it ... So directly apt-get install Ceph is OK

7. Create a cluster monitor

Ceph-deploy Mon Create Monster

8. Collect the key from the remote node to the current folder

Ceph-deploy Gatherkeys Monster

9. Add OSD to the directory where we mount the virtual disk

Ceph-deploy OSD Prepare Monster:/srv/ceph/osd0ceph-deploy OSD prepare MONSTER:/SRV/CEPH/OSD1

10. Activate OSD

sudo ceph-deploy OSD activate Monster:/srv/ceph/osd0sudo ceph-deploy OSD Activate MONSTER:/SRV/CEPH/OSD1

[Ceph_deploy] [ERROR] Runtimeerror:failed to execute command:ceph-disk-v activate--mark-init upstart--mount/srv/ceph/osd0

When you encounter an error such as the one shown above when activating, use the command sudo chown ceph:ceph/srv/ceph/osd0 to solve the problem (but previously did the OSD disk, which seems to be solved by this method ...). ）

11. Copy the admin key to other nodes

Ceph-deploy Admin Monster

12. Verification
