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.

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.

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.
