ceph16.2.5编译

ceph 16.25工程管理脚本用了dnf和dnf-utlis，centos（软件库比较老）安装部署比较麻烦，所以最好用最新的fedora做编译环境。

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

Build Prerequisites

The list of Debian or RPM packages dependencies can be installed with:

./install-deps.sh

[root@localhost ceph]# ./install-deps.sh

yum -y update

Building Ceph

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 ceph.spec.in or debian/rules to see which configuration options are specified for production builds.

Build instructions:

./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 2.5GiB memory.)

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.

ARGS="-DCMAKE_C_COMPILER=gcc-7" ./do_cmake.sh

To build only certain targets use:

ninja [target name]

To install:

ninja install

CMake Options

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" \
..

To view an exhaustive list of -D options, you can invoke cmake with:

cmake -LH

If you often pipe ninja to less and would like to maintain the diagnostic colors for errors and warnings (and if your compiler supports it), you can invoke cmake with:

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

./make-dist

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,

../src/stop.sh

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 ctest:

cd build
ninja
ctest -j$(nproc)

(Note: Many targets built from src/test are not run using ctest. 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)]

(Note: 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 with the -j flag:

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:

man ctest

Building the Documentation

Prerequisites

The list of package dependencies for building the documentation can be found in doc_deps.deb.txt:

sudo apt-get install `cat doc_deps.deb.txt`

Building the Documentation

To build the documentation, ensure that you are in the top-level /ceph directory, and execute the build script. For example:

admin/build-doc

修改 vi .gitmodules 将命令行里的https改为git重新执行。

我改了之后发现不生效，所以我是直接找报错里面的地址 自己下载

git clone  git://github.com/ceph/spdk.git

然后将下载的结果spdk按提示“into submodule path '/home/ceph/src/spdk"移动到src下
