如果需要要修改Ceph源码，就要自己构建安装包，然后指定ceph-deploy的安装源。 本文主要介绍从git上clone源码，然后用rpmbuild打包，最后用ceph-deploy安装。 环境为Centos6.5，ceph版本v0.94.5(hammer)。

Ceph RPM打包

官方的RPM打包教程http://ceph.com/docs/master/install/build-ceph/。 如果只是尝试打包的话，这个教程基本够了，下面主要讲从git源码开始。

1. git(recursive会把子模块一起克隆)

git clone --recursive https://github.com/ceph/ceph.git
cd ceph
git checkout v0.94.5 -f

2. 安装打包依赖

./install-deps.sh
yum install rpm-build rpmdevtools

3. 准备rpmbuild目录

rpmdev-setuptree

4. 配置编译

./autogen.sh
./configure
./make_dist 0.94.5
cp ceph-0.94.5.tar.bz2 ~/rpmbuild/SOURCES/
cp rpm/init-ceph.in-fedora.patch ~/rpmbuild/SOURCES/
cp ceph.spec.in ~/rpmbuild/SPECS/ceph.spec

5. 开始build，编译完成会在~/rpmbuild/RPMS/x86_64目录下生成打包文件

rpmbuild -ba ~/rpmbuild/SPECS/ceph.spec

经过漫长的等待，终于打包完成：

注意，编译大概需要近15G存储空间

完毕。
