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
|
|
:term:`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 :term:`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. See `Add Keys`_ 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.
|
|
|
|
|
|
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., ``hammer``, ``jewel``) 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'
|
|
|
|
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::
|
|
|
|
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}
|
|
|
|
The major releases of Ceph are summarized at: :doc:`/releases`.
|
|
|
|
Every second major release is considered Long Term Stable (LTS). Critical
|
|
bugfixes are backported to LTS releases until their retirement. Since retired
|
|
releases are no longer maintained, we recommend that users upgrade their
|
|
clusters regularly - preferably to the latest LTS release.
|
|
|
|
.. 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-jewel/ {codename} main'
|
|
|
|
For early Linux distributions, you may execute the following command::
|
|
|
|
echo deb https://download.ceph.com/debian-jewel/ $(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
|
|
|
|
Ceph on ARM processors requires Google's memory profiling tools (``google-perftools``).
|
|
The Ceph repository should have a copy at
|
|
https://download.ceph.com/packages/google-perftools/debian. ::
|
|
|
|
echo deb https://download.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 https://download.ceph.com/debian-testing/ $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list
|
|
|
|
.. tip:: 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
|
|
------------
|
|
|
|
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., ``hammer``, ``jewel``,
|
|
etc.) and ``{distro}`` with your Linux distribution (e.g., ``el7``, 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`_.
|
|
|
|
|
|
Add Ceph Development
|
|
====================
|
|
|
|
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
|
|
=================
|
|
|
|
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 https://download.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::
|
|
|
|
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-jewel/{distro}/noarch/ceph-{version}.{distro}.noarch.rpm'
|
|
|
|
For example, for CentOS 7 (``el7``)::
|
|
|
|
su -c 'rpm -Uvh https://download.ceph.com/rpm-jewel/el7/noarch/ceph-release-1-0.el7.noarch.rpm'
|
|
|
|
You can download the RPMs directly from::
|
|
|
|
https://download.ceph.com/rpm-jewel
|
|
|
|
|
|
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'
