pyslurm安装出错

问题

之前为了省事，没从源码安装slurm，在 Ubuntu 18.04 上根据这篇博客通过 apt 的方式直接装了slurm-wlm的17.11.02版本。

在安装pyslurm的时候，发现提示找不到slurm的安装路径，或者提示pyslurm版本和本机slurm版本不匹配。

解决方法（给你们看的）

创建软链接
ln -sf /usr/include/slurm-wlm/ /usr/include/slurm
mkdir /usr/lib/slurm
ln -sf /usr/lib/x86_64-linux-gnu /usr/lib/slurm/lib

安装对应版本pyslurm
git clone -b 17-11-12  https://github.com/PySlurm/pyslurm.git
cd pyslurm
python setup.py build  --slurm-inc=/usr/include/ --slurm-lib=/usr/lib/slurm

具体踩坑过程（给自己看的）

从github下载pyslurm，进入根目录，运行安装目录报错，提示找不到slurm的安装路径。

root@manager:~/pyslurm# python setup.py build -slurm=/usr/lib/x86_64-linux-gnu/slurm-wlm/
INFO:

INFO: Clean - completed
ERROR: Build - Cannot locate the Slurm include in /usr/include

由于我们安装的是slurm-wlm，搜索一下其存在的目录，发现是存在相关安装文件和动态链接库的，主要是pyslurm只能识别名为slurm的文件夹

root@manager:~# sudo find / -name slurm-wlm
/usr/share/doc/slurm-wlm
/usr/share/doc-base/slurm-wlm
/usr/lib/x86_64-linux-gnu/slurm-wlm

因此，我们需要手动创建两个slurm软链接指向slurm-wlm的文件夹

ln -sf /usr/include/slurm-wlm/ /usr/include/slurm
mkdir /usr/lib/slurm
ln -sf /usr/lib/x86_64-linux-gnu /usr/lib/slurm/lib

重新执行安装命令，美滋滋再次报错pyslurm和已安装slurm版本不符

root@manager:~/pyslurm# python setup.py build  --slurm-inc=/usr/include/ --slurm-lib=/usr/lib/slurm
INFO:

ERROR: Build - Incorrect slurm version detected, requires Slurm 19.05

主要是因为github直接clone的是最新的19.x版本，而apt安装的slurm只是17.x版本，所以需要下载对应的17.x版本pyslurm

在github找到对应tag之后，重新下载pyslurm

root@manager:~# git clone -b 17-11-12  https://github.com/PySlurm/pyslurm.git

到这里终于下载好对应版本pyslurm了，重新运行安装命令

到此，已经正常安装完pyclurm，可以import pyslurm开干了敢动。
