一.背景
由于某地项目需要需要ceph支持redhat6.4，因此需要在redhat6.4 basic server进行源码的编译以及rpm包的生成。
二.获取ceph源码
获取ceph源码有几种方式，可以选择从git库上获取，也可以在官网获取，值得一提的是，如果在git库上获取时，默认是只clone 主分支源码到当前工作目录，并不会递归clone ceph submodule里的代码，因此在编译时常出现模块代码不存在的问题。
这里采用git库的方式获取代码：
1.获取ceph git主分支
git clone –recursive https://github.com/ceph/ceph.git
2.获取ceph redhat分支
git checkout -b local origin/rh-jewel
可以从ceph 官网下载打包好的
http://download.ceph.com/tarballs/
三 编译源码
在生成rpm包之前，我们需要保证源码编译环境正常，因此我们先编译ceph源码，这里获取的是10.2.5的代码。
执行
./autogen.sh
按照提示对libtool进行安装
yum install libtool
执行
./configure –with-radosgw
按照提示安装gcc-c++
yum install gcc-c++
再次执行configure，我们发现提示如下错误
这里写图片描述
很明显，jewel版本的代码要求支持c++11特性，因此我们升级gcc。
获取gcc-4.8.1
wget http://ftp.gnu.org/gnu/gcc/gcc-4.8.1/gcc-4.8.1.tar.gz
tar xzf gcc-4.8.1.tar.gz
cd gcc-4.8.1
./contrib/download_prerequisites //依赖库
cd ..
mkdir build_gcc4.8.1
cd build_gcc4.8.1
../gcc-4.8.1/configure --prefix=/usr -enable-checking=release --enable-languages=c,c++ --disable-multilib
make -j4
make install
到此，我们gcc升级完成，可以重新编译ceph源码。
回到ceph源码目录，重新执行configure –with-radosgw，报以下错误
这里写图片描述
这个错误是缺少cython包
在安装此安装包以前需要安装python2.7，默认系统自带2.6，需要进行升级。
获取epel源
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
wget https://rhel6.iuscommunity.org/ius-release.rpm
安装源
rpm -Uvh epel-release-latest-6.noarch.rpm ius-release.rpm
重新执行configure还会报比较多的包缺失，这里不一一赘述。在我的系统中，安装以下安装包：
yum install snappy-devel leveldb-devel libblkid-devel libudeve-dev expat-devel keyutils-libs-devel cryptopp cryptopp-devel cryptopp fuse-devel fuse-libs libuuid-devel libedit-devel libatomic_ops-devel libatomic libaio-devel xfsprogs-devel openldap-devel fuse-python libudev libudev-devel boost boost-devel openssl openssl-devel libcurl libidn-devel curl fcgi-devel fcgi libcurl-devel
在这里，需要注意的是boost的版本应该是1.53：
默认boost-random安装完后 生成的so名字为 libboost_random-mt.so.1.46.0,但是configure扫描环境变量扫描文件名为libboost_random-mt.so,因此需要生成软链接。
ln -s /usr/lib64/libboost_random.so.1.53.0 /usr/lib64/libboost_random-mt.so
ln -s /usr/lib64/libboost_random.so.1.53.0 /usr/lib64/libboost_random.so
boost安装完成后，重新编译ceph
重新configure –with-radosgw再make源码，在这之前需要修改rbd-nbd，在redhat6.4版本上内核不支持nbd，如果需要编译rbd-nbd需要对内核进行升级到3.10以上。
rpm -Uvh kernel-3.10.105-1.el6.x86_64.rpm
然而，这次又出错了，报 gcc rados.c cephfs.c No such file，很困惑，提示里看到一个关键词pybind。
百度了一下pybind这个工具，是将python代码转换为c代码的，rados.c cephfs.c是通过这个工具转换出来的，然后再进行编译，另外在代码里看到很多python2.6的字眼，我们不是将2.6升级成2.7了么，怎么还是2.6？
因此决定将rpm包卸载，进行源码安装。
rpm -e python27 python27-libs
源码编译安装python2.7源码 ,
tar xvf Python-2.7.13.tgz
./configure –prefix=/usr/local/python27 --enable-shared
如果要生成共享库libpython2.7.so、libpython2.7.so.1.0、libpython2.7.a（.so为动态库，.a为静态库），加上--enable-shared
修改 Modules/Setup 文件
vi Modules/Setup
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
#SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
默认这块是注释的，放开注释即开。这块功能是开启SSL模块，不然会出现安装完毕后，提示找不到ssl模块的错误。
make 添加-j4使用多核加速.
make -j4
make install
用软连接进行2.6 2.7版本转换
ln -sf /usr/local/python2.7/bin/python /usr/bin/python
ln -sf /usr/local/python2.7/lib/libpython2.7.so /usr/lib64/libpython2.7.so
ln -sf /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib64/libpython2.7.so.1.0
添加python2.7的环境变量:
vi /etc/profile
export PYTHON_HOME=/usr/local/python2.7/bin;
export PATH=$PATH:$PYTHON_HOME;
使其生效
source /etc/profile
安装setuptools。
wget –no-check-certificate https://pypi.python.org/packages/41/5f/6da80400340fd48ba4ae1c673be4dc3821ac06cd9821ea60f9c7d32a009f/setuptools-38.4.0.zip#md5=3426bbf31662b4067dc79edc0fa21a2e
首先进入setuptools的解目录，执行命令
python setup.py install
安装pip
wget https://pypi.python.org/packages/11/b6/abcb525026a4be042b486df43905d6893fb04f05aac21c32c638e939e447/pip-9.0.1.tar.gz#md5=35f01da33009719497f01a4ba69d63c9
装好setuptools后，在进入pip-9.0.1的解压目录,执行命令
python setup.py install
安装完毕后，再次进行make，报cython.build module找不到，安装cython。
pip install distribute
pip install Cython
ln -s /usr/local/bin/sphinx-build /usr/local/bin/sphinx-1.0-build
编译安装
编译安装
make -j4
make install
配置环境变量
vi /etc/profile
export CEPH_HOME=/usr/local/ceph/bin;
export PATH=$PATH:$PYTHON_HOME:$CEPH_HOME;
拷贝库文件
cp -R /usr/local/ceph/lib/* /usr/lib64/
cp -R /usr/local/ceph/lib/python2.7/site-packages/* /usr/local/python2.7/lib/python2.7/site-packages
再次make，终于成功了。

四 生成rpm包
在源码编译成功后，表明环境可以正式进行rpm打包了。
进入ceph目录，make dist-bzip2
执行完成后，生成对应的.tar.bz2文件。
准备rpmbuild工作目录
mkdir ~/rpmbuild/ ~/rpmbuild/BUILD ~/rpmbuild/BUILDROOT ~/rpmbuild/RPMS ~/rpmbuild/SOURCES ~/rpmbuild/SPECS ~/rpmbuild/SRPMS
准备构建文件
cp ceph.tar.bz2 ~/rpmbuild/SOURCES
cp ceph/rpm/init-ceph.in-fedora.patch ~/rpmbuild/SOURCES
cp ceph/ceph.spec ~/rpmbuild/SPECS
生成rpm包
rpmbuild -bb ~/rpmbuild/SPECS/ceph.spec
生成rpm包提示会有很多依赖，其中boost库的已经安装，只需要在ceph.spec里面将其注释掉，另外注释掉policyhelp就可以打包了
