Get Packages

To install Ceph and other enabling software, you need to retrieve packages from the Ceph repository. Follow this guide to get packages; then, proceed to the Install Ceph Object Storage.

Getting Packages

There are two ways to get packages:

• Add Repositories: Adding repositories is the easiest way to get packages, because package management tools will retrieve the packages and all enabling software for you in most cases. However, to use this approach, 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.

Requirements

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. There are two keys: one for releases (common) and one for development (programmers and QA only). Choose the key that suits your needs. See Add Keys for details.
• Ceph Extras: (Required) The Ceph Extras repository provides newer Ceph-enabled versions of packages which are already provided in your Linux distribution, but where newer versions are required to support Ceph. Examples of newer versions of available packages include QEMU for CentOS/RHEL distribution and iSCSI among others. If you intend to use any of the foregoing packages, you must add the Ceph Extras repository or download the packages manually. This repository also contains Ceph dependencies for those who intend to install Ceph manually. See Add Ceph Extras for details.
• Ceph: (Required) All Ceph deployments require Ceph release packages, except for deployments that use development packages (development, QA, and bleeding edge deployments only). See Add Ceph for details.
• 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. See Add Ceph Development for details.
• Apache/FastCGI: (Optional) If you are deploying a Ceph Object Storage service, you must install Apache and FastCGI. Ceph provides Apache and FastCGI builds that are identical to those available from Apache, but with 100-continue support. If you want to enable Ceph Object Gateway daemons with 100-continue support, you must retrieve Apache/FastCGI packages from the Ceph repository. See Add Apache/FastCGI for details.

If you intend to download packages manually, see Section Download Packages.

Add Keys

Add a key to your system’s list of trusted keys to avoid a security warning. For major releases (e.g., dumpling, emperor, firefly) and development releases (release-name-rc1, release-name-rc2), use the release.asc key. For development testing packages, use the autobuild.asc key (developers and QA).

APT

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

wget -q -O- 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc' | sudo apt-key add -

To install the autobuild.asc key, execute the following (QA and developers only):

wget -q -O- 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc' | sudo apt-key add -

RPM

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

sudo rpm --import 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc'

To install the autobuild.asc key, execute the following (QA and developers only):

sudo rpm --import 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc'

Add Ceph Extras

Some Ceph deployments require newer Ceph-enabled versions of packages that are already available in your Linux distribution. For example, Ceph Extras contains newer Ceph-enabled packages for the SCSI target framework and QEMU packages for RPMs. The repository also contains curl, leveldb and other Ceph dependencies. Add the Ceph Extras repository to ensure you obtain these additional packages from the Ceph repository.

Debian Packages

Add our Ceph Extras package repository to your system’s list of APT sources.

echo deb http://ceph.com/packages/ceph-extras/debian $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-extras.list

RPM Packages

Note

ceph-extras on RPM-based systems is only needed on EL6-based distributions (RHEL 6, CentOS 6, Scientific Linux 6). It is not needed for Fedora or RHEL 7+.

For RPM packages, add our package repository to your /etc/yum.repos.d repos (e.g., ceph-extras.repo). Some Ceph packages (e.g., QEMU) must take priority over standard packages, so you must ensure that you set priority=2.

[ceph-extras]
name=Ceph Extras Packages
baseurl=http://ceph.com/packages/ceph-extras/rpm/{distro}/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-extras-noarch]
name=Ceph Extras noarch
baseurl=http://ceph.com/packages/ceph-extras/rpm/{distro}/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-extras-source]
name=Ceph Extras Sources
baseurl=http://ceph.com/packages/ceph-extras/rpm/{distro}/SRPMS
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

Add Ceph

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:

http://ceph.com/debian-{release-name}

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

http://ceph.com/rpm-{release-name}

The major releases of Ceph include:

• Giant: Giant is the most recent major release of Ceph. These packages are recommended for anyone deploying Ceph in a production environment. Critical bug fixes are backported and point releases are made as necessary.
• Firefly: Firefly is the sixth major release of Ceph. These packages are recommended for anyone deploying Ceph in a production environment. Firefly is a long-term stable release, so critical bug fixes are backported and point releases are made as necessary.
• Emperor: Emperor is the fifth major release of Ceph. These packages are are old and no longer supported, so we recommend that users upgrade to Firefly immediately.
• Dumpling: Dumpling is the fourth major release of Ceph. These packages are older and not recommended for new users, but critical bug fixes are still backported as necessary. We encourage all Dumpling users to update to Firefly as soon as they are able to do so.
• Argonaut, Bobtail, Cuttlefish: These are the first three releases of Ceph. These packages are old and no longer supported, so we recommend that users upgrade to a supported version.

For European users, there is also a mirror in the Netherlands at: http://eu.ceph.com/

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 http://ceph.com/debian-firefly/ {codename} main'

For early Linux distributions, you may execute the following command:

echo deb http://ceph.com/debian-firefly/ $(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 http://ceph.com/debian-{release-name}/ {codename} main'

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

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

Ceph on ARM processors requires Google’s memory profiling tools (google-perftools). The Ceph repository should have a copy at http://ceph.com/packages/google-perftools/debian.

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

RPM Packages

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., dumpling, emperor, etc.) and {distro} with your Linux distribution (e.g., el6, rhel6, etc.). You may view http://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 $basearch
baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-noarch]
name=Ceph noarch packages
baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=http://ceph.com/rpm-{ceph-release}/{distro}/SRPMS
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

For development release packages, you may specify the repository for development releases instead.

[ceph]
name=Ceph packages for $basearch/$releasever
baseurl=http://ceph.com/rpm-testing/{distro}/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-noarch]
name=Ceph noarch packages
baseurl=http://ceph.com/rpm-testing/{distro}/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=http://ceph.com/rpm-testing/{distro}/SRPMS
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

For specific packages, you may retrieve them by specifically 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 or up2date. Replace {distro} with your Linux distribution, and {release} with the specific release of Ceph:

su -c 'rpm -Uvh http://ceph.com/rpms/{distro}/x86_64/ceph-{release}.el6.noarch.rpm'

You can download the RPMs directly from:

http://ceph.com/rpm-testing

Add Ceph Development

Development repositories use the autobuild.asc key to verify 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.

Debian Packages

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

Add our package repository to your system’s list of APT sources, but replace {BRANCH} with the branch you’d like to use (e.g., chef-3, wip-hack, master). See the gitbuilder page for a complete list of distributions we build.

echo deb http://gitbuilder.ceph.com/ceph-deb-$(lsb_release -sc)-x86_64-basic/ref/{BRANCH} $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list

RPM Packages

For current development branches, you may add a Ceph entry to the /etc/yum.repos.d directory. Create a ceph.repo file. In the example below, replace {distro} with your Linux distribution (e.g., centos6, rhel6, etc.), and {branch} with the name of the branch you want to install.

[ceph-source]
name=Ceph source packages
baseurl=http://gitbuilder.ceph.com/ceph-rpm-{distro}-x86_64-basic/ref/{branch}/SRPMS
enabled=0
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

You may view http://gitbuilder.ceph.com directory to see which distributions Ceph supports.

Add Apache/FastCGI

Ceph Object Gateway works with ordinary Apache and FastCGI libraries. However, Ceph builds Apache and FastCGI packages that support 100-continue. To use the Ceph Apache and FastCGI packages, add them to your repository.

Debian Packages

Add our Apache and FastCGI packages to your system’s list of APT sources if you intend to use 100-continue.

echo deb http://gitbuilder.ceph.com/apache2-deb-$(lsb_release -sc)-x86_64-basic/ref/master $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-apache.list
echo deb http://gitbuilder.ceph.com/libapache-mod-fastcgi-deb-$(lsb_release -sc)-x86_64-basic/ref/master $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph-fastcgi.list

RPM Packages

You may add a Ceph entry to the /etc/yum.repos.d directory. Create a ceph-apache.repo file. In the example below, replace {distro} with your Linux distribution (e.g., el6, rhel6, etc.). You may view http://gitbuilder.ceph.com directory to see which distributions Ceph supports.

[apache2-ceph-noarch]
name=Apache noarch packages for Ceph
baseurl=http://gitbuilder.ceph.com/apache2-rpm-{distro}-x86_64-basic/ref/master
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

[apache2-ceph-source]
name=Apache source packages for Ceph
baseurl=http://gitbuilder.ceph.com/apache2-rpm-{distro}-x86_64-basic/ref/master
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

Repeat the forgoing process by creating a ceph-fastcgi.repo file.

[fastcgi-ceph-basearch]
name=FastCGI basearch packages for Ceph
baseurl=http://gitbuilder.ceph.com/mod_fastcgi-rpm-{distro}-x86_64-basic/ref/master
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

Download Packages

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 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 http://ceph.com/debian-{release}/pool/main/c/ceph/ceph_{version}{distro}_{arch}.deb

RPM Packages

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

su -c 'rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm'

Ceph requires the following packages:

• snappy
• leveldb
• gdisk
• python-argparse
• gperftools-libs

Packages are currently built for the RHEL/CentOS6 (el6), Fedora 18 and 19 (f18 and f19), OpenSUSE 12.2 (opensuse12.2), and SLES (sles11) platforms. The repository package installs the repository details on your local system for use with yum or up2date. Replace {distro} with your distribution.

su -c 'rpm -Uvh http://ceph.com/rpm-firefly/{distro}/noarch/ceph-{version}.{distro}.noarch.rpm'

For example, for CentOS 6 (el6):

su -c 'rpm -Uvh http://ceph.com/rpm-firefly/el6/noarch/ceph-release-1-0.el6.noarch.rpm'

You can download the RPMs directly from:

http://ceph.com/rpm-firefly

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 http://ceph.com/rpm-{release-name}/{distro}/noarch/ceph-{version}.{distro}.noarch.rpm'
