编译Ceph

下载ceph-17.2.7源码。

wget https://download.ceph.com/tarballs/ceph-17.2.7.tar.gz --no-check-certificate

合入UCX patch（将ceph-17.2.7-ucx.patch放入对应目录下）。

tar -zxvf ceph-17.2.7.tar.gz
cd ceph-17.2.7
patch -p1 < ceph-17.2.7-ucx.patch

修改ceph.spec文件（欧拉系统）。

sed -i 's/redhat-rpm-config/openEuler-rpm-config/g' ceph.spec
sed -i 's#%if 0%{?fedora} || 0%{?rhel}#%if 0%{?fedora} || 0%{?rhel} || 0%{?openEuler}#' ceph.spec
sed -i 's#%if 0%{?rhel} || 0%{?fedora}#%if 0%{?rhel} || 0%{?fedora} || 0%{?openEuler}#' ceph.spec
sed -i '1a\%define _binaries_in_noarch_packages_terminate_build 0' ceph.spec
sed -i '2a\%define _unpackaged_files_terminate_build 0' ceph.spec
sed -i 's/DWITH_GRAFANA:BOOL=ON/DWITH_GRAFANA:BOOL=ON \\\n    \-DWITH_UCX=\/usr/g' ceph.spec

编译Ceph。

cd ..
tar cfv ceph-17.2.7.tar.bz2 ceph-17.2.7/
cp ceph-17.2.7/ceph.spec /root/rpmbuild/SPECS/
cp ceph-17.2.7.tar.bz2 /root/rpmbuild/SOURCES/
rpmbuild -bb /root/rpmbuild/SPECS/ceph.spec

mv /root/rpmbuild/RPMS/aarch64/* /home/local_rpm/
mv /root/rpmbuild/RPMS/noarch/* /home/local_rpm/

在物理机上将编好的RPM包导入到出包容器。

podman cp openeuler2203sp3_build:/home/local_rpm openeuler2203sp3_release:/home/

若Ceph源码src/osd/SnapMapper.cc与fmt包的版本不匹配时，会出现编译报错。报错时需要将src/osd/SnapMapper.cc文件中fmt::format相关代码行修改，修改类似如下。
