Checking out the source
You can clone from github with
git clone [email protected]:ceph/ceph
or, if you are not a github user,
git clone git://github.com/ceph/ceph
Ceph contains many git submodules that need to be checked out with
git submodule update --init --recursive
The list of Debian or RPM packages dependencies can be installed with:
Note that these instructions are meant for developers who are
compiling the code for development and testing. To build binaries
suitable for installation we recommend you build deb or rpm packages
or refer to the
debian/rules to see which
configuration options are specified for production builds.
./do_cmake.sh cd build ninja
(do_cmake.sh now defaults to creating a debug build of ceph that can be up to 5x slower with some workloads. Please pass "-DCMAKE_BUILD_TYPE=RelWithDebInfo" to do_cmake.sh to create a non-debug release.
The number of jobs used by
ninja is derived from the number of CPU cores of
the building host if unspecified. Use the
-j option to limit the job number
if the build jobs are running out of memory. On average, each job takes around
This assumes you make your build dir a subdirectory of the ceph.git
checkout. If you put it elsewhere, just point
CEPH_GIT_DIR to the correct
path to the checkout. Any additional CMake args can be specified by setting ARGS
before invoking do_cmake. See cmake options
for more details. Eg.
To build only certain targets use:
ninja [target name]
If you run the
cmake command by hand, there are many options you can
set with "-D". For example, the option to build the RADOS Gateway is
defaulted to ON. To build without the RADOS Gateway:
cmake -DWITH_RADOSGW=OFF [path to top-level ceph directory]
Another example below is building with debugging and alternate locations for a couple of external dependencies:
cmake -DLEVELDB_PREFIX="/opt/hyperleveldb" \ -DCMAKE_INSTALL_PREFIX=/opt/ceph -DCMAKE_C_FLAGS="-Og -g3 -gdwarf-4" \ ..
Ceph has several bundled dependencies such as Boost, RocksDB and Arrow. By
default, cmake will build these bundled dependencies from source instead of
using libraries that are already installed on the system. You can opt-in to
using these system libraries, provided they meet the minimum version required
by Ceph, with cmake options like
cmake -DWITH_SYSTEM_BOOST=ON [...]
To view an exhaustive list of -D options, you can invoke
If you often pipe
less and would like to maintain the
diagnostic colors for errors and warnings (and if your compiler
supports it), you can invoke
cmake -DDIAGNOSTICS_COLOR=always ...
Then you'll get the diagnostic colors when you execute:
ninja | less -R
Other available values for 'DIAGNOSTICS_COLOR' are 'auto' (default) and 'never'.
Building a source tarball
To build a complete source tarball with everything needed to build from source and/or build a (deb or rpm) package, run
This will create a tarball like ceph-$version.tar.bz2 from git. (Ensure that any changes you want to include in your working directory are committed to git.)
Running a test cluster
To run a functional test cluster,
cd build ninja vstart # builds just enough to run vstart ../src/vstart.sh --debug --new -x --localhost --bluestore ./bin/ceph -s
Almost all of the usual commands are available in the bin/ directory. For example,
./bin/rados -p rbd bench 30 write ./bin/rbd create foo --size 1000
To shut down the test cluster,
To start or stop individual daemons, the sysvinit script can be used:
./bin/init-ceph restart osd.0 ./bin/init-ceph stop
Running unit tests
To build and run all tests (in parallel using all processors), use
cd build ninja ctest -j$(nproc)
(Note: Many targets built from src/test are not run using
Targets starting with "unittest" are run in
ninja check and thus can
be run with
ctest. Targets starting with "ceph_test" can not, and should
be run by hand.)
When failures occur, look in build/Testing/Temporary for logs.
To build and run all tests and their dependencies without other unnecessary targets in Ceph:
cd build ninja check -j$(nproc)
To run an individual test manually, run
ctest with -R (regex matching):
ctest -R [regex matching test name(s)]
ctest does not build the test it's running or the dependencies needed
to run it)
To run an individual test manually and see all the tests output, run
ctest with the -V (verbose) flag:
ctest -V -R [regex matching test name(s)]
To run tests manually and run the jobs in parallel, run
ctest -j [number of jobs]
There are many other flags you can give
ctest for better control
over manual test execution. To view these options run:
