1.安装依赖环境

yum install gcc make python-devel openssl-devel graphviz autoconf automake rpm-build redhat-rpm-config libtool

2.下载 kernel 源码：

yum install "kernel-devel-uname-r == $(uname -r)"

3.创建rpmbuild目录结构

mkdir rpmbuild/{BUILD,SOURCES,SPECS,RPMS,BUILDROOT} -pv

4.下载源码，解压，编译

cp ceph-12.2.8.tar.gz rpmbuild/SOURCES/

tar -xvf ceph-12.2.8.tar.gz

cp ceph-12.2.8/ceph.spec rpmbuild/SPECS/

5.下载ceph依赖包

cd ceph-12.2.8/ && ./install-deps.sh

6.编译

rpmbuild -bb rpmbuild/SPECS/ceph.spec --nocheck

或者：（指定rpmbuild目录）

rpmbuild --define "_topdir ${dir:-/wangjq/openstack_rocky/open_source/ceph_rpm/rpmbuild}" -bb ceph.spec --without cephfs_java --without selinux --without ceph_test_package --without lttng --with cephfs_shell --without amqp_endpoint --without libradosstriper --without ocf

7.问题解决：

问题1：/usr/share/selinux/devel/policyhelp 被 ceph-2:12.2.8-0.el7.centos.x86_64 需要

解决：yum install selinux-policy-doc -y
