获取ceph源码

从https://docs.ceph.com/en/latest/releases/找到pacific版本对应的tag为16.2.15

git clone https://github.com/ceph/ceph.git

# 查看所有tag
git ls-remote --tags origin |grep 16.2.
618f440892089921c3e944a991122ddc44e60516        refs/tags/v16.2.15^{}

# 根据git log的commit找到pacifc的release tag为v16.2.15
commit 618f440892089921c3e944a991122ddc44e60516 (HEAD -> ceph-pacific-learning, tag: v16.2.15, tag: ls, origin/ceph-pacific-learning)
Author: Ceph Release Team <ceph-maintainers@ceph.io>
Date:   Mon Feb 26 19:21:09 2024 +0000

    16.2.15

    Signed-off-by: Ceph Release Team <ceph-maintainers@ceph.io>
# 或者 git show v16.2.15，可以确认即可

# 切换到pacific的release tag
git checkout v16.2.15

# 这个tag是一个快照，不可修改，所以创建我们自己的分支
git checkout -b ceph-pacific-learning

编译

拉取submodule网络问题

执行命令git submodule update --init --recursive --progress更新子模块

如果子模块拉取失败：

• 方法一：这个地址会记录最新国内可用的github镜像地址，https://fcp7.com/github-mirror-daily-updates.html，修改ceph顶层目录下的.gitmodule，例如对于[submodule "src/erasure-code/jerasure/gf-complete"]，将url = https://github.com/ceph/gf-complete.git部分替换为镜像的地址如下：

[submodule "ceph-object-corpus"]
	path = ceph-object-corpus
	url = https://gitclone.com/ceph/ceph-object-corpus.git
[submodule "src/civetweb"]
	path = src/civetweb
	url = https://gitclone.com/ceph/civetweb
[submodule "src/erasure-code/jerasure/jerasure"]
	path = src/erasure-code/jerasure/jerasure
	url = https://gitclone.com/ceph/jerasure.git
	branch = v2-ceph
[submodule "src/erasure-code/jerasure/gf-complete"]
	path = src/erasure-code/jerasure/gf-complete
	url = https://gitclone.com/ceph/gf-complete.git
	branch = v3-ceph
[submodule "src/rocksdb"]
	path = src/rocksdb
	url = https://gitclone.com/ceph/rocksdb
	ignore = dirty
[submodule "ceph-erasure-code-corpus"]
	path = ceph-erasure-code-corpus
	url = https://gitclone.com/ceph/ceph-erasure-code-corpus.git

执行git submodule sync --recursive更新git拉取的地址，再次执行git submodule update --init --recursive --progress

• 方法二：如果方法一中的镜像源没有地址，根据拉取失败的提示fatal: clone of 'https://github.com/spdk/dpdk.git' into submodule path '/data/ceph-learning/src/spdk/dpdk' failed，手动多拉取几次git clone https://github.com/spdk/dpdk.git /data/ceph-learning/src/spdk/dpdk --progress，或者将https换成git执行git clone git://github.com/spdk/dpdk.git /data/ceph-learning/src/spdk/dpdk --progress
• 方法三：那种方式上网，解决99%的编译问题

安装依赖

./install-deps.sh

如果是openEuler系统

index 7e137d687f1..b22d45f409d 100755

+++ b/install-deps.sh

         builddepcmd="dnf -y builddep --allowerasing"
         echo "Using dnf to install dependencies"
         case "$ID" in

do_cmake.sh

1. cmake -LH可以看到cmake可用参数和描述信息，例如

// ceph-mgr is enabled
WITH_MGR:BOOL=ON

// Build the mgr/dashboard frontend using `npm`
WITH_MGR_DASHBOARD_FRONTEND:BOOL=ON

// build OCF-compliant cluster resource agent
WITH_OCF:BOOL=OFF

dashboard依赖node、ng的一堆包，系统版本不同依赖问题也不同，编译会很麻烦，如果用不到它可以关掉：

./do_cmake.sh -DWITH_MGR_DASHBOARD_FRONTEND=OFF

如果需要dashboard，直接执行./do_cmake.sh后，到build目录下，按照下面的编译dashboard配置后，再回来执行make

编译

执行./do_cmake.sh后会在ceph源码顶层目录下生成一个build目录

cd build
make -j16

Tips：make过程中也会下载一些软件包，没有那种方式上网可能会导致超时失败，失败后可以继续make -j16增量编译

vstart启动

要使用vstart启动ceph，还需要编译相关环境，在build目录下

make vstart

MON=1 OSD=2 MGR=1 RGW=1 NFS=1 ../src/vstart.sh -d -n -x

问题

1. 无法访问dashboard，ceph -s输出Module 'dashboard' has failed: No module named 'routes'，缺python包pip3 install routes即可
2. 启动cephfs可能会失败缺包，手动安装

Requirements
------------

The following packages are required to enable CephFS and RGW exports with nfs-ganesha:

-  ``nfs-ganesha``, ``nfs-ganesha-ceph``, ``nfs-ganesha-rados-grace`` and
   ``nfs-ganesha-rados-urls`` packages (version 3.3 and above)

编译dashboard

如果使用-DWITH_MGR_DASHBOARD_FRONTEND=OFF关了dashboard的话可以忽略这个

安装nodejs

方法一 下载编译好的源码包

wget https://nodejs.org/dist/v16.14.2/node-v16.14.2-linux-x64.tar.xz
xz -d node-v16.14.2-linux-x64.tar.xz
tar -xvf node-v16.14.2-linux-x64.tar

mkdir /usr/local/soft
mv node-v16.14.2-linux-x64 /usr/local/soft

ln -s /usr/local/soft/node-v16.14.2-linux-x64/bin/node /usr/local/bin/node
ln -s /usr/local/soft/node-v16.14.2-linux-x64/bin/npm /usr/local/bin/npm

npm config set registry https://registry.npmmirror.com
npm install -g @angular/cli@16.2.0
ln -s /usr/local/soft/node-v16.14.2-linux-x64/lib/node_modules/@angular/cli/bin/ng.js /usr/local/bin/ng

方法二 nvm安装node（推荐）

# 复制脚本到主机
https://github.com/nvm-sh/nvm/blob/master/install.sh

bash install.sh
# 重新打开终端
nvm ls-remote --lts

nvm install v16.14.2
npm -g install @angular/cli@16.2.10

编译nodeenv

旧版本的ceph编译dashboard会有nodejs和angular/cli版本冲突的问题

# /data/ceph-learning换成自己的ceph源码顶层目录
cd /data/ceph-learning/src/pybind/mgr/dashboard && vim CMakeLists.txt

# 修改 COMMAND ${mgr-dashboard-nodeenv-dir}/bin/nodeenv --verbose ${node_mirror_opt} -p --node=12.18.2
# 为 COMMAND ${mgr-dashboard-nodeenv-dir}/bin/nodeenv --verbose ${node_mirror_opt} -p --node=16.14.2

cd /data/ceph-learning/build

root@yielde:/data/ceph-learning/build# make mgr-dashboard-nodeenv

其他

boost下载慢

生成build后，可以先下载好 https://download.ceph.com/qa/boost_1_73_0.tar.bz2，放到/data/ceph-learning/build/boost/src目录下

root@yielde:/data/ceph-learning/build/boost/src# ls -lh
total 105M
drwxr-xr-x 2 root root 4.0K Feb  9 14:38 Boost
-rw-r--r-- 1 root root 105M Feb  9 15:27 boost_1_73_0.tar.bz2
drwxr-xr-x 2 root root 4.0K Feb  9 14:55 Boost-stamp

总结

其实棘手的问题就两个，一是网络方面众所周知的问题访问git和其他一些仓库会超时失败，二是前端相关的nodejs组件等版本问题导致编译失败。要耐心查看报错，修改CmakeList.txt或Makefile、手动下载相关软件包到目录，一步一步解决。

附一个大佬写的vscode+clangd的调试环境配置，我还没尝试：
