build Ceph
编译需要的时间比较长，建议在screen里面编译，防止terminal连接中断
如果在根目录挂载的文件系统下编译，根目录至少有100G可用空间 如果是其他目录单独挂载的文件系统下编译，根目录至少有50G可用空间，其他目录至少有100G空间
1. 环境
| 组件名称 | 版本 | 备注 |
|---|---|---|
| 操作系统 | CentOS Linux release 7.8.2003 (Core) | |
| 内核 | 3.10.0-1127.el7.x86_64 | |
| Ceph分支版本 | v15.2.15 |
2. 下载Ceph代码
git clone git@github.com:ceph/ceph.git
3. 选择分支
我这里选择tag v15.2.15
git checkout v15.2.15
4. update submodule
git submodule update --init --recursive
5. 下载依赖
如果使用官方提供的
install-deps.sh会有几个包装不上，例如golang-github-prometheus-prometheus，手动安装依赖
yum install -y redhat-lsb-core yum-utils java-devel sharutils checkpolicy selinux-policy-devel python-cherrypy python-werkzeug bc gperf cmake cryptsetup fuse-devel gcc-c++ gdbm gperftools-devel jq leveldb-devel libaio-devel libblkid-devel libcurl-devel libudev-devel libtool libxml2-devel make parted perl pkgconfig python python-devel python-nose python-requests python-virtualenv snappy-devel udev util-linux valgrind-devel which xfsprogs xfsprogs-devel xmlstarlet yasm boost-random btrfs-progs nss-devel keyutils-libs-devel libibverbs-devel openldap-devel openssl-devel Cython python-prettytable python-sphinx python34-devel python34-setuptools python34-Cython lttng-ust-devel libbabeltrace-devel expat-devel redhat-rpm-config junit fcgi-devel selinux-policy-doc rdma-core-devel devtoolset-8-gcc-c++ lz4-devel liboath-devel librabbitmq-devel python2-Cython python36-Cython python36-setuptools python36-devel CUnit-devel librdmacm-devel cmake3 libcap-ng-devel libnl3-devel librdkafka-devel fuse3-devel python36-sphinx
6. 安装devtoolset
安装devtoolset主要为了解决ceph使用了C++17的特性，但CentOS7默认源安装的GCC版本不兼容问题,错误信息如下
GCC 7+ required due to C++17 requirements
yum install centos-release-scl
yum install devtoolset-8
# 每次编译source一下
source /opt/rh/devtoolset-8/enable
7. 编译二进制
编译服务器CPU越多编译越快，24核的半小时编译完成，8核每次编译两个多小时
cd build
make -j$(nproc)
编译完最后输出如下
编译产物 build/bin 下的二进制文件
8. 编译rpm
8.1. 先编译dist包
./make-dist
编译产物 ceph-15.2.15-0-g2dfb188.tar.bz2 boost_1_72_0.tar.bz2 dashboard_frontend.tar rook_ceph_client.tar
8.2. 编译rpm包
8.2.1. 编译srpm包
./make-srpm.sh
编译产物 ceph-15.2.15-0.g2dfb188.el7.src.rpm
8.2.2. 编译rpm包
编译rpm包时默认spec文件中有make，所以编译耗时跟编译二进制是一样的
rpmbuild -D"_sourcedir `pwd`" -D"_specdir `pwd`" -D"_srcrpmdir `pwd`" -ba ceph.spec
