Build Ceph
|
|
============
|
|
|
|
You can get Ceph software by retrieving Ceph source code and building it yourself.
|
|
To build Ceph, you need to set up a development environment, compile Ceph,
|
|
and then either install in user space or build packages and install the packages.
|
|
|
|
Build Prerequisites
|
|
===================
|
|
|
|
|
|
.. tip:: Check this section to see if there are specific prerequisites for your
|
|
Linux/Unix distribution.
|
|
|
|
A debug build of Ceph may take around 40 gigabytes. If you want to build Ceph in
|
|
a virtual machine (VM) please make sure total disk space on the VM is at least
|
|
60 gigabytes.
|
|
|
|
Please also be aware that some distributions of Linux, like CentOS, use Linux
|
|
Volume Manager (LVM) for the default installation. LVM may reserve a large
|
|
portion of disk space of a typical sized virtual disk for the operating system.
|
|
|
|
Before you can build Ceph source code, you need to install several libraries
|
|
and tools::
|
|
|
|
./install-deps.sh
|
|
|
|
.. note:: Some distributions that support Google's memory profiler tool may use
|
|
a different package name (e.g., ``libgoogle-perftools4``).
|
|
|
|
Build Ceph
|
|
==========
|
|
|
|
Ceph is built using cmake. To build Ceph, navigate to your cloned Ceph
|
|
repository and execute the following::
|
|
|
|
cd ceph
|
|
./do_cmake.sh
|
|
cd build
|
|
make
|
|
|
|
.. note:: By default do_cmake.sh will build a debug version of ceph that may
|
|
perform up to 5 times slower with certain workloads. Pass
|
|
'-DCMAKE_BUILD_TYPE=RelWithDebInfo' to do_cmake.sh if you would like to
|
|
build a release version of the ceph executables instead.
|
|
|
|
.. topic:: Hyperthreading
|
|
|
|
You can use ``make -j`` to execute multiple jobs depending upon your system. For
|
|
example, ``make -j4`` for a dual core processor may build faster.
|
|
|
|
See `Installing a Build`_ to install a build in user space.
|
|
|
|
Build Ceph Packages
|
|
===================
|
|
|
|
To build packages, you must clone the `Ceph`_ repository. You can create
|
|
installation packages from the latest code using ``dpkg-buildpackage`` for
|
|
Debian/Ubuntu or ``rpmbuild`` for the RPM Package Manager.
|
|
|
|
.. tip:: When building on a multi-core CPU, use the ``-j`` and the number of
|
|
cores * 2. For example, use ``-j4`` for a dual-core processor to accelerate
|
|
the build.
|
|
|
|
|
|
Advanced Package Tool (APT)
|
|
---------------------------
|
|
|
|
To create ``.deb`` packages for Debian/Ubuntu, ensure that you have cloned the
|
|
`Ceph`_ repository, installed the `Build Prerequisites`_ and installed
|
|
``debhelper``::
|
|
|
|
sudo apt-get install debhelper
|
|
|
|
Once you have installed debhelper, you can build the packages::
|
|
|
|
sudo dpkg-buildpackage
|
|
|
|
For multi-processor CPUs use the ``-j`` option to accelerate the build.
|
|
|
|
|
|
RPM Package Manager
|
|
-------------------
|
|
|
|
To create ``.rpm`` packages, ensure that you have cloned the `Ceph`_ repository,
|
|
installed the `Build Prerequisites`_ and installed ``rpm-build`` and
|
|
``rpmdevtools``::
|
|
|
|
yum install rpm-build rpmdevtools
|
|
|
|
Once you have installed the tools, setup an RPM compilation environment::
|
|
|
|
rpmdev-setuptree
|
|
|
|
Fetch the source tarball for the RPM compilation environment::
|
|
|
|
wget -P ~/rpmbuild/SOURCES/ https://download.ceph.com/tarballs/ceph-<version>.tar.bz2
|
|
|
|
Or from the EU mirror::
|
|
|
|
wget -P ~/rpmbuild/SOURCES/ http://eu.ceph.com/tarballs/ceph-<version>.tar.bz2
|
|
|
|
Extract the specfile::
|
|
|
|
tar --strip-components=1 -C ~/rpmbuild/SPECS/ --no-anchored -xvjf ~/rpmbuild/SOURCES/ceph-<version>.tar.bz2 "ceph.spec"
|
|
|
|
Build the RPM packages::
|
|
|
|
rpmbuild -ba ~/rpmbuild/SPECS/ceph.spec
|
|
|
|
For multi-processor CPUs use the ``-j`` option to accelerate the build.
