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
ninja
See Installing a Build to install a build in user space and Ceph README.md doc for more details on build.
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.
