============== 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. 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: (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 :term:`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 :term:`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., ``hammer``, ``jewel``) 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://download.ceph.com/keys/release.asc' | sudo apt-key add - To install the ``autobuild.asc`` key, execute the following (QA and developers only):: wget -q -O- 'https://download.ceph.com/keys/autobuild.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' To install the ``autobuild.asc`` key, execute the following (QA and developers only):: sudo rpm --import 'https://download.ceph.com/keys/autobuild.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. The most recent LTS release is Jewel (10.2.x). .. tip:: For international users: There might be a mirror close to you where 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 international users: There might be a mirror close to you where 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 development release packages, you may specify the repository for development releases instead. :: [ceph] name=Ceph packages for $basearch/$releasever baseurl=https://download.ceph.com/rpm-testing/{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-testing/{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-testing/{distro}/SRPMS enabled=0 priority=2 gpgcheck=1 gpgkey=https://download.ceph.com/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``. 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 international users: There might be a mirror close to you where download Ceph from. For more information see: `Ceph Mirrors`_. 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} $(lsb_release -sc) main | sudo tee /etc/apt/sources.list.d/ceph.list RPM Packages ------------ For current development branches, you may add a Ceph entry to the ``/etc/yum.repos.d`` directory. Create a ``ceph.repo`` file. In the example below, replace ``{distro}`` with your Linux distribution (e.g., ``el7``), and ``{branch}`` with the name of the branch you want to install. :: [ceph-source] name=Ceph source packages baseurl=http://gitbuilder.ceph.com/ceph-rpm-{distro}-x86_64-basic/ref/{branch}/SRPMS enabled=0 gpgcheck=1 gpgkey=https://download.ceph.com/keys/autobuild.asc You may view http://gitbuilder.ceph.com directory to see which distributions Ceph supports. Add Apache/FastCGI ================== Ceph Object Gateway works with ordinary Apache and FastCGI libraries. However, Ceph builds Apache and FastCGI packages that support 100-continue. To use the Ceph Apache and FastCGI packages, add them to your repository. Debian Packages --------------- Add our Apache and FastCGI packages to your system's list of APT sources if you intend to use 100-continue. :: echo deb http://gitbuilder.ceph.com/apache2-deb-$(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., ``el7``). 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 gpgkey=https://download.ceph.com/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 gpgkey=https://download.ceph.com/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 gpgkey=https://download.ceph.com/keys/autobuild.asc [fastcgi-ceph-noarch] name=FastCGI noarch packages for Ceph baseurl=http://gitbuilder.ceph.com/mod_fastcgi-rpm-{distro}-x86_64-basic/ref/master enabled=1 priority=2 gpgcheck=1 gpgkey=https://download.ceph.com/keys/autobuild.asc [fastcgi-ceph-source] name=FastCGI source packages for Ceph baseurl=http://gitbuilder.ceph.com/mod_fastcgi-rpm-{distro}-x86_64-basic/ref/master enabled=0 priority=2 gpgcheck=1 gpgkey=https://download.ceph.com/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 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.
