Get Packages

To install Ceph and other enabling software, you need to retrieve packages from the Ceph repository.

There are three ways to get packages:

  • Cephadm: Cephadm can configure your Ceph repositories for you based on a release name or a specific Ceph version. Each Ceph Node in your cluster must have internet access.

  • Configure Repositories Manually: You can manually configure your package management tool to retrieve Ceph packages and all enabling software. Each Ceph Node in your cluster must have internet access.

  • Download Packages Manually: Downloading packages manually is a convenient way to install Ceph if your environment does not allow a Ceph Node to access the internet.

Install packages with cephadm

  1. Download the cephadm script

curl --silent --remote-name --location https://github.com/ceph/ceph/raw/pacific/src/cephadm/cephadm
chmod +x cephadm

  1. Configure the Ceph repository based on the release name:

    ./cephadm add-repo --release nautilus

    For Octopus (15.2.0) and later releases, you can also specify a specific version:

    ./cephadm add-repo --version 15.2.1

    For development packages, you can specify a specific branch name:

    ./cephadm add-repo --dev my-branch

  2. Install the appropriate packages. You can install them using your package management tool (e.g., APT, Yum) directly, or you can also use the cephadm wrapper. For example:

    ./cephadm install ceph-common

Configure Repositories Manually

All Ceph deployments require Ceph packages (except for development). You should also add keys and recommended packages.

  • Keys: (Recommended) Whether you add repositories or download packages manually, you should download keys to verify the packages. If you do not get the keys, you may encounter security warnings.

  • Ceph: (Required) All Ceph deployments require Ceph release packages, except for deployments that use development packages (development, QA, and bleeding edge deployments only).

  • Ceph Development: (Optional) If you are developing for Ceph, testing Ceph development builds, or if you want features from the bleeding edge of Ceph development, you may get Ceph development packages.

Add Keys

Add a key to your system’s list of trusted keys to avoid a security warning. For major releases (e.g., luminous, mimic, nautilus) and development releases (release-name-rc1, release-name-rc2), use the release.asc key.

APT

To install the release.asc key, execute the following:

wget -q -O- 'https://download.ceph.com/keys/release.asc' | sudo apt-key add -

RPM

To install the release.asc key, execute the following:

sudo rpm --import 'https://download.ceph.com/keys/release.asc'

Ceph Release Packages

Release repositories use the release.asc key to verify packages. To install Ceph packages with the Advanced Package Tool (APT) or Yellowdog Updater, Modified (YUM), you must add Ceph repositories.

You may find releases for Debian/Ubuntu (installed with APT) at:

https://download.ceph.com/debian-{release-name}

You may find releases for CentOS/RHEL and others (installed with YUM) at:

https://download.ceph.com/rpm-{release-name}

For Octopus and later releases, you can also configure a repository for a specific version x.y.z. For Debian/Ubuntu packages:

https://download.ceph.com/debian-{version}

For RPMs:

https://download.ceph.com/rpm-{version}

The major releases of Ceph are summarized at: Releases

Tip

For non-US users: There might be a mirror close to you where to download Ceph from. For more information see: Ceph Mirrors.

Debian Packages

Add a Ceph package repository to your system’s list of APT sources. For newer versions of Debian/Ubuntu, call lsb_release -sc on the command line to get the short codename, and replace {codename} in the following command.

sudo apt-add-repository 'deb https://download.ceph.com/debian-pacific/ {codename} main'

For early Linux distributions, you may execute the following command

echo deb https://download.ceph.com/debian-pacific/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list

For earlier Ceph releases, replace {release-name} with the name with the name of the Ceph release. You may call lsb_release -sc on the command line to get the short codename, and replace {codename} in the following command.

sudo apt-add-repository 'deb https://download.ceph.com/debian-{release-name}/ {codename} main'

For older Linux distributions, replace {release-name} with the name of the release

echo deb https://download.ceph.com/debian-{release-name}/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list

For development release packages, add our package repository to your system’s list of APT sources. See the testing Debian repository for a complete list of Debian and Ubuntu releases supported.

echo deb https://download.ceph.com/debian-testing/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list

For non-US users: There might be a mirror close to you where to download Ceph from. For more information see: Ceph Mirrors.

RPM Packages

RHEL

For major releases, you may add a Ceph entry to the /etc/yum.repos.d directory. Create a ceph.repo file. In the example below, replace {ceph-release} with a major release of Ceph (e.g., |stable-release|) and {distro} with your Linux distribution (e.g., el8, etc.). You may view https://download.ceph.com/rpm-{ceph-release}/ directory to see which distributions Ceph supports. Some Ceph packages (e.g., EPEL) must take priority over standard packages, so you must ensure that you set priority=2.

[ceph]
name=Ceph packages for $basearch
baseurl=https://download.ceph.com/rpm-{ceph-release}/{distro}/$basearch
enabled=1
priority=2
gpgcheck=1
gpgkey=https://download.ceph.com/keys/release.asc

[ceph-noarch]
name=Ceph noarch packages
baseurl=https://download.ceph.com/rpm-{ceph-release}/{distro}/noarch
enabled=1
priority=2
gpgcheck=1
gpgkey=https://download.ceph.com/keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=https://download.ceph.com/rpm-{ceph-release}/{distro}/SRPMS
enabled=0
priority=2
gpgcheck=1
gpgkey=https://download.ceph.com/keys/release.asc

For specific packages, you may retrieve them by downloading the release package by name. Our development process generates a new release of Ceph every 3-4 weeks. These packages are faster-moving than the major releases. Development packages have new features integrated quickly, while still undergoing several weeks of QA prior to release.

The repository package installs the repository details on your local system for use with yum. Replace {distro} with your Linux distribution, and {release} with the specific release of Ceph

su -c 'rpm -Uvh https://download.ceph.com/rpms/{distro}/x86_64/ceph-{release}.el7.noarch.rpm'

You can download the RPMs directly from

https://download.ceph.com/rpm-testing

Tip

For non-US users: There might be a mirror close to you where to download Ceph from. For more information see: Ceph Mirrors.

openSUSE Leap 15.1

You need to add the Ceph package repository to your list of zypper sources. This can be done with the following command

zypper ar https://download.opensuse.org/repositories/filesystems:/ceph/openSUSE_Leap_15.1/filesystems:ceph.repo
openSUSE Tumbleweed

The newest major release of Ceph is already available through the normal Tumbleweed repositories. There’s no need to add another package repository manually.

Ceph Development Packages

If you are developing Ceph and need to deploy and test specific Ceph branches, ensure that you remove repository entries for major releases first.

DEB Packages

We automatically build Ubuntu packages for current development branches in the Ceph source code repository. These packages are intended for developers and QA only.

Add the package repository to your system’s list of APT sources, but replace {BRANCH} with the branch you’d like to use (e.g., wip-hack, master). See the shaman page for a complete list of distributions we build.

curl -L https://shaman.ceph.com/api/repos/ceph/{BRANCH}/latest/ubuntu/$(lsb_release -sc)/repo/ | sudo tee /etc/apt/sources.list.d/shaman.list

Note

If the repository is not ready an HTTP 504 will be returned

The use of latest in the url, means it will figure out which is the last commit that has been built. Alternatively, a specific sha1 can be specified. For Ubuntu Xenial and the master branch of Ceph, it would look like

curl -L https://shaman.ceph.com/api/repos/ceph/master/53e772a45fdf2d211c0c383106a66e1feedec8fd/ubuntu/xenial/repo/ | sudo tee /etc/apt/sources.list.d/shaman.list

Warning

Development repositories are no longer available after two weeks.

RPM Packages

For current development branches, you may add a Ceph entry to the /etc/yum.repos.d directory. The the shaman page can be used to retrieve the full details of a repo file. It can be retrieved via an HTTP request, for example

curl -L https://shaman.ceph.com/api/repos/ceph/{BRANCH}/latest/centos/7/repo/ | sudo tee /etc/yum.repos.d/shaman.repo

The use of latest in the url, means it will figure out which is the last commit that has been built. Alternatively, a specific sha1 can be specified. For CentOS 7 and the master branch of Ceph, it would look like

curl -L https://shaman.ceph.com/api/repos/ceph/master/53e772a45fdf2d211c0c383106a66e1feedec8fd/centos/7/repo/ | sudo tee /etc/apt/sources.list.d/shaman.list

Warning

Development repositories are no longer available after two weeks.

Note

If the repository is not ready an HTTP 504 will be returned

Download Packages Manually

If you are attempting to install behind a firewall in an environment without internet access, you must retrieve the packages (mirrored with all the necessary dependencies) before attempting an install.

Debian Packages

Ceph requires additional third party libraries.

  • libaio1

  • libsnappy1

  • libcurl3

  • curl

  • libgoogle-perftools4

  • google-perftools

  • libleveldb1

The repository package installs the repository details on your local system for use with apt. Replace {release} with the latest Ceph release. Replace {version} with the latest Ceph version number. Replace {distro} with your Linux distribution codename. Replace {arch} with the CPU architecture.

wget -q https://download.ceph.com/debian-{release}/pool/main/c/ceph/ceph_{version}{distro}_{arch}.deb

RPM Packages

Ceph requires additional third party libraries. To add the EPEL repository, execute the following

sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Ceph requires the following packages:

  • snappy

  • leveldb

  • gdisk

  • python-argparse

  • gperftools-libs

Packages are currently built for the RHEL/CentOS7 (el7) platforms. The repository package installs the repository details on your local system for use with yum. Replace {distro} with your distribution.

su -c 'rpm -Uvh https://download.ceph.com/rpm-pacific/{distro}/noarch/ceph-{version}.{distro}.noarch.rpm'

For example, for CentOS 8 (el8)

su -c 'rpm -Uvh https://download.ceph.com/rpm-pacific/el8/noarch/ceph-release-1-0.el8.noarch.rpm'

You can download the RPMs directly from

https://download.ceph.com/rpm-pacific

For earlier Ceph releases, replace {release-name} with the name with the name of the Ceph release. You may call lsb_release -sc on the command line to get the short codename.

su -c 'rpm -Uvh https://download.ceph.com/rpm-{release-name}/{distro}/noarch/ceph-{version}.{distro}.noarch.rpm'
