How to Install Ceph on OpenBSD

Ceph is an open source distributed storage system that provides high performance, reliability, and scalability. In this tutorial, we will explain how to install Ceph on OpenBSD.

Prerequisites

Before installing Ceph on OpenBSD, you will need the following:

• A running OpenBSD installation
• At least 2 nodes with OpenBSD installed

Step 1: Install Required Packages

Before installing Ceph, we need to install some required packages:

pkg_add bash cmake git perl gmake libatomic libgcc libstdc++ libtool wget autoconf automake py3-setuptools

Step 2: Download Ceph

We will download the latest version of Ceph from its official website:

wget -O ceph.tar.gz https://download.ceph.com/tarballs/ceph-15.2.13.tar.gz

Step 3: Extract Ceph

Now, we will extract the Ceph tarball:

tar -xvf ceph.tar.gz
cd ceph-15.2.13

Step 4: Build Ceph

We will now build Ceph using the following commands:

./install-deps.sh
./do_cmake.sh
make

Step 5: Install Ceph

Once the build is complete, install Ceph using the following command:

make install

Step 6: Configure Ceph

Before configuring Ceph, we need to create a new user and group:

groupadd ceph
useradd -m -g ceph -s /bin/bash ceph

We will now create a new configuration file:

cp ceph.conf.sample /etc/ceph/ceph.conf

Edit the configuration file and replace the cluster name, monitor IP addresses, and OSD device path with your own settings.

Step 7: Start Ceph

We can now start the Ceph service with the following command:

systemctl start ceph

To check the status of the Ceph service, run:

systemctl status ceph

Conclusion

We have successfully installed Ceph on OpenBSD. You can now start using Ceph for distributed storage.
