BeeGFS开发环境搭建4-源码编译

如果我们需要动态调试和开发BeeGFS，那么就需要自己手动编译了，而且能够用最简单的方式运行起来，下面就讲解自己探索和分析的过程。

• 参考文档：

# https://git.beegfs.io/pub # https://www.beegfs.io/wiki/BuildFromSources 

初始化环境

• 安装依赖的软件包：

$ yum install -y libuuid-devel libibverbs-devel librdmacm-devel libattr-devel redhat-rpm-config rpm-build xfsprogs-devel cppunit cppunit-devel zlib-devel openssl-devel sqlite sqlite-devel ant gcc-c++ gcc redhat-lsb-core java-devel 

获取官方源码

• 获取指定版本的源码：

$ git clone https://git.beegfs.io/pub/v6.git beegfs-v6 $ cd beegfs-v6 $ git tag -l 6.1 6.10 6.11 6.12 6.13 6.14 6.15 6.16 6.17 6.18 6.19 6.2 6.3 6.4 6.5 6.6 6.7 6.8 6.9 $ git checkout -b v6.18 6.18 

• 进行简单的查看和验证：

$ git show 6.18 | head -n12 tag 6.18 Tagger: Bernd Lietzow <bernd.lietzow@itwm.fraunhofer.de> Date: Mon Mar 12 16:09:35 2018 +0100 created tag 6.18 commit aee03250ea19502952d2f187e73134996abaec5b Author: Bernd Lietzow <bernd.lietzow@itwm.fraunhofer.de> Date: Mon Mar 12 16:09:13 2018 +0100 updated to release 6.18 $ git branch -av master 4a69532 updated to release 6.19 * v6.18 aee0325 updated to release 6.18 remotes/origin/HEAD -> origin/master remotes/origin/master 4a69532 updated to release 6.19 

分析Makefile

• 查看他的Makefile，BeeGFS自己实现了一个简单的Makefile工程模板，所有的子模块都使用这一套模板来变异，十分简单高效：

$ make -j$(nproc) -C beegfs_meta/build help [VER] BEEGFS_VERSION="19.5-git8" BEEGFS_VERSION_CODE=18023688 make: Entering directory `/root/beegfs-v6/fhgfs_meta/build' Optional arguments: BEEGFS_DEBUG=1 Enables debug information and symbols BEEGFS_DEBUG_OPT=1 Enables internal debug code, but compiled with optimizations CXX=<compiler> Specifies a c++ compiler DISTCC=distcc Enables the usage of distcc V=1 Print command lines of tool invocations BEEGFS_COMMON_PATH=<path> Path to the beegfs_common directory BEEGFS_OPENTK_PATH=<path> Path to the beegfs_opentk_lib directory BEEGFS_THIRDPARTY_PATH=<path> Path to the beegfs_thirdparty directory Targets: all (default) build only clean delete compiled files help print this help message rpm create an rpm package deb create debian package file make: Leaving directory `/root/beegfs-v6/fhgfs_meta/build' $ cat beegfs_meta/build/Makefile # This is the beegfs_meta makefile. # It creates an ELF executable. # # Use "make help" to find out about configuration options. CAN_PACKAGE := yes include $(or $(root-dir),../..)/build/Makefile $(call build-executable,\ beegfs-meta,\ $(shell find ../source -iname '*.cpp'),\ opentk common cppunit dl) # enable special reference DirInode debug code ifneq ($(BEEGFS_DEBUG_RELEASE_DIR),) # extra release dir debugging CXXFLAGS += -DBEEGFS_DEBUG_RELEASE_DIR endif $ cat build/Makefile ... override V := $(if $V,,@) all: ... rpm: ./make-rpm ... # build-executable # # define a new executable for the build # arguments: # #1: name of the executable # #2: sources # #3: required libraries build-executable = $(eval $(call -build-executable-fragment,$(strip $1),$2,$3)) define -build-executable-fragment all: $1 CLEANUP_FILES += $1 $(addsuffix .o,$2) $(addsuffix .d,$2) $(addsuffix .o,$2): CXXFLAGS += \ $(foreach lib,$3,$(call resolve-dep-cflags,$(lib))) $1: LDFLAGS += \ -Wl,--start-group $(foreach lib,$3,$(call resolve-dep-ldflags,$(lib))) -Wl,--end-group $1: $(addsuffix .o,$2) $(foreach lib,$3,$(call resolve-dep-deps,$(lib))) @echo "[LD] $$@" $$V$$(CXX) -o $$@ $(addsuffix .o,$2) $$(LDFLAGS) -include $(addsuffix .d,$2) endef 

分析RPM脚本

• 查看他构建RPM包的方法，直接打包源码目录，并使用一个RPM SPEC文件模板，使用sed动态生成一个SPEC文来进行构建：

$ cat beegfs_meta/build/make-rpm #!/bin/bash NAME=beegfs-meta SPEC_FILE=${NAME}.spec source ../../beegfs-version arch=`uname -m` if [[ "$arch" == "x86_64" ]]; then BUILDARCH="$arch" elif [[ "$arch" =~ 86 ]]; then BUILDARCH="i686" else BUILDARCH=$arch fi CONCURRENCY=${MAKE_CONCURRENCY:-4} export BEEGFS_VERSION_PATH=`pwd`/../../beegfs-version set -e pushd ../ TOOLS_ROOT=`pwd` popd BUILD="${TOOLS_ROOT}/build" mkdir -p $BUILD/buildroot/{BUILD,RPMS,S{RPMS,PECS,OURCES}} rm -f $BUILD/buildroot/SOURCES/*.tgz ROOT_DIR=${ROOT_DIR:-`(cd ../..; pwd)`} BEEGFS_COMMON_PACKAGE_PATH=${BEEGFS_COMMON_PACKAGE_PATH:-`readlink -f ../../beegfs_common_package`} set +e # test if redhat-rpm-config is installed. If so, we must not specify # %debug_package in the spec file, if not installed we need to define it # in order to strip binaries and to build a debug package rpm -qa redhat-rpm-config | grep redhat-rpm-config NEED_DEBUG_DEFINE=$? set -e pushd $TOOLS_ROOT tar czf $BUILD/buildroot/SOURCES/${NAME}-${BEEGFS_VERSION}.tgz --exclude=buildroot/* * cd $BUILD sed -e "s#%BEEGFS_COMMON_PACKAGE_PATH%#$BEEGFS_COMMON_PACKAGE_PATH#g" \ -e "s/%NAME%/$NAME/g" \ -e "s/%BEEGFS_VERSION%/$BEEGFS_VERSION/g" \ -e "s/%BUILDARCH%/$BUILDARCH/g" \ -e "s/%MAKE_CONCURRENCY%/$CONCURRENCY/g" \ -e "s/%NEED_DEBUG_DEFINE%/$NEED_DEBUG_DEFINE/g" \ ${SPEC_FILE}.in > ${SPEC_FILE} rpmbuild --clean -bb ${SPEC_FILE} --define "_topdir $BUILD/buildroot/" -D "ROOT_DIR $ROOT_DIR" popd rm -fr /var/tmp/${NAME}-root/ rm -f /var/tmp/rpm-tmp.* 

分析RPM配置

• 查看SPEC中引用的参数，正式上面的脚本替换后的结果：

$ cat beegfs_meta/build/beegfs-meta.spec %define buildarch x86_64 %define BEEGFS_COMMON_PACKAGE_PATH /root/beegfs-v6/fhgfs_common_package %define BEEGFS_VERSION %VER%-%RELEASE_STR% %define MAKE_CONCURRENCY 4 %define NEED_DEBUG_DEFINE 0 %define BEEGFS_VERSION 19.4-git17 %define VER %(echo '%{BEEGFS_VERSION}' | cut -d - -f 1) %define BEEGFS_RELEASE_STR %(echo '%{BEEGFS_VERSION}-' | cut -d - -f 2) %define EPOCH %(echo '%{VER}' | cut -d . -f 1) ... %build cd build make \ root-dir=%{ROOT_DIR} \ BEEGFS_VERSION=%{BEEGFS_VERSION} \ -j %{MAKE_CONCURRENCY} ... $ grep -rHn root-dir beegfs_meta beegfs_meta/build/Makefile:8:include $(or $(root-dir),../..)/build/Makefile beegfs_meta/build/beegfs-meta.spec.in:74: root-dir=%{ROOT_DIR} \ beegfs_meta/build/beegfs-meta.spec:74: root-dir=%{ROOT_DIR} \ 

正式开始编译

• 先编译依赖的函数库：

$ make -j$(nproc) -C beegfs_thirdparty/build $ make -j$(nproc) -C beegfs_opentk_lib/build $ make -j$(nproc) -C beegfs_common/build 

• 根据需要编译所需的模块：

$ make -j$(nproc) -C beegfs_meta/build clean # make -j$(nproc) -C beegfs_meta/build BEEGFS_DEBUG=1 $ make -j$(nproc) -C beegfs_meta/build [VER] BEEGFS_VERSION="19.5-git9" BEEGFS_VERSION_CODE=18023689 make: Entering directory `/root/beegfs-v6/fhgfs_meta/build' [CXX] ../source/app/App.cpp.o [CXX] ../source/components/DatagramListener.cpp.o [CXX] ../source/app/config/Config.cpp.o ... [CXX] ../source/toolkit/BuddyCommTk.cpp.o [CXX] ../source/toolkit/StorageTkEx.cpp.o [CXX] ../source/toolkit/XAttrTk.cpp.o [LD] beegfs-meta make: Leaving directory `/root/beegfs-v6/fhgfs_meta/build' $ file /root/beegfs-v6/beegfs_meta/build/beegfs-meta /root/beegfs-v6/beegfs_meta/build/beegfs-meta: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=be90bbf04db11b7dcf46d29240b7cb20ab676cf5, not stripped 

• 也可以编译Debug版本，但是要注意，此时前面依赖的函数库也得编译成Debug版本，否则运行时会直接崩溃：

$ make -j$(nproc) -C beegfs_meta/build BEEGFS_DEBUG=1 [VER] BEEGFS_VERSION="19.5-git9" BEEGFS_VERSION_CODE=18023689 make: Entering directory `/root/beegfs-v6/fhgfs_meta/build' make: Nothing to be done

分析启动脚本

• BeeGFS使用Systemd进行管理，其配置文件中直接指定运行程序的路径和参数：

$ systemctl status beegfs-meta.service ● beegfs-meta.service - Start BeeGFS Metadata Server Loaded: loaded (/usr/lib/systemd/system/beegfs-meta.service; enabled; vendor preset: disabled) Active: active (running) since Wed 2019-05-08 22:33:19 CST; 10min ago Process: 48475 ExecStop=/etc/init.d/beegfs-meta stop (code=exited, status=0/SUCCESS) Process: 48685 ExecStart=/etc/init.d/beegfs-meta start (code=exited, status=0/SUCCESS) Main PID: 48691 (beegfs-meta/Mai) Tasks: 442 Memory: 363.9M CGroup: /system.slice/beegfs-meta.service └─48691 /opt/beegfs/sbin/beegfs-meta cfgFile=/etc/beegfs/beegfs-meta.conf pidFile=/var/run/beegfs-meta.pid May 08 22:33:19 sacd02 systemd[1]: Starting Start BeeGFS Metadata Server...

• 为了保持跟早期的SysInitV保持兼容，整整的程序执行脚本在init.d目录中：

运行编译程序

• 我们只需要把BeeGFS的SysInitV的启动脚本中改成自己编译的程序，就可以直接无缝运行了：
