How to Install Ceph on Elementary OS Latest

Ceph is an open source, distributed storage system popular among many large organizations. Installing Ceph on Elementary OS is relatively easy. This tutorial will guide you through the process of installing Ceph on your Elementary OS latest version.

Step 1: Update Your System

Before proceeding with the installation process of Ceph, we need to update our system by running the following command:

sudo apt-get update

Step 2: Install Dependencies

We need to install the dependencies before installing Ceph. To install the dependencies, run the following command:

sudo apt-get install -y ceph-deploy python-pip python-argparse

Step 3: Create Ceph User

Now we need to create a new user account for Ceph, and add it to the sudo group. Run the following command to create a Ceph user:

sudo adduser ceph

Once the user is created, add it to the sudo group:

sudo usermod -a -G sudo ceph

Step 4: Configure SSH Authorization

We also need to configure SSH authorization for our Ceph user. To do that, run the following command:

sudo su - ceph

ssh-keygen

Now, enter the location where you want to save your SSH key and provide a strong passphrase or leave it empty.

Next, copy the public key into the authorized keys file to enable passwordless login:

cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys

Step 5: Deploy Ceph

Now that your system dependencies are installed and your SSH configuration is complete, it's time to deploy Ceph. To deploy Ceph, run the following command:

ceph-deploy new localhost

Once the new cluster is created, run the following command to configure the installation:

ceph-deploy install localhost

Step 6: Monitor the Cluster

You can now start monitoring the Ceph cluster by running the following commands:

ceph-deploy mon create-initial

ceph -s

Step 7: Create OSD (Object Storage Device)

Run the following command to create an OSD:

ceph-deploy osd create --data /dev/sdb localhost

Replace /dev/sdb with your actual hard drive device.

Conclusion

That’s it! You've successfully installed Ceph on your Elementary OS latest version. You can now start using the powerful distributed storage system for your enterprise.
