【新教程】Ubuntu 24.04 单节点安装slurm

背景

网上教程老旧，不适用。

详细步骤

1、安装slurm

sudo apt install slurm-wlm slurm-wlm-doc -y

检查是否安装成功：

slurmd --version

如果得到slurm-wlm 23.11.4，表明安装成功。
2、配置slurm。
使用命令：

sudo vi /etc/slurm/slurm.conf

在其中输入以下内容：

ClusterName=cool  [自定义集群名称]
ControlMachine=master
#ControlAddr=
#BackupController=
#BackupAddr=
#
MailProg=/usr/bin/s-nail
SlurmUser=slurm
#SlurmdUser=slurm
SlurmctldPort=6817SlurmdPort=6818
AuthType=auth/munge
#JobCredentialPrivateKey=
#JobCredentialPublicCertificate=
StateSaveLocation=/var/spool/slurmctld
SlurmdSpoolDir=/var/spool/slurmd
SwitchType=switch/none
MpiDefault=none
SlurmctldPidFile=/var/run/slurmctld.pid
SlurmdPidFile=/var/run/slurmd.pid
ProctrackType=proctrack/pgid

#

#
# LOGGINGSlurmctldDebug=info
SlurmctldLogFile=/var/log/slurm/slurmctld.log
SlurmdDebug=info
SlurmdLogFile=/var/log/slurm/slurmd.log
JobCompType=jobcomp/none
#JobCompLoc=
#
# ACCOUNTING
#JobAcctGatherType=jobacct_gather/linux
#JobAcctGatherFrequency=30
#
#AccountingStorageType=accounting_storage/slurmdbd
#AccountingStorageHost=
#AccountingStorageLoc=
#AccountingStoragePass=
#AccountingStorageUser=
#
# COMPUTE NODESPartitionName=CPU Nodes=master Default=NO MaxTime=INFINITE State=UP
#NodeName=master State=UNKNOWN
NodeName=master Sockets=1 CoresPerSocket=4 ThreadsPerCore=1 State=UNKNOWN

其中，要修改以下参数，请勿和上述配置完全一样;
ControlMachine=你的主机名，查看方法hostname
PartitionName=队列名称，可以自己起，比如改为CPU
Nodes=你的主机名，查看方法hostname
NodeName=你的主机名，查看方法hostname
Sockets=你服务器cpu的个数，查看方法cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
CoresPerSocket=每个cpu的核数，查看方法cat /proc/cpuinfo| grep "cpu cores"| uniq
ThreadsPerCore填写方法：
运行下面的脚本;

#!/bin/bash
cpunum=`cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l`
echo "CPU 个数: $cpunum";
cpuhx=`cat /proc/cpuinfo | grep "cores" | uniq | awk -F":" '{print $2}'`
echo "CPU 核心数：$cpuhx" ; 
cpuxc=`cat /proc/cpuinfo | grep "processor" | wc -l`
echo "CPU 线程数：$cpuxc" ;if [[ `expr $cpunum\*$[cpuhx*2] ` -eq $cpuxc ]];
thenecho "开启了超线程"
elseecho "未开启超线程"
fi

如果开启了超线程填2，否则填1.
3、创建文件夹。使用以下命令，创建所需的文件夹：

sudo mkdir -p /var/spool/slurmd
sudo mkdir -p /var/spool/slurmctld
sudo chown -R slurm:slurm /var/spool/slurmd
sudo chown -R slurm:slurm /var/spool/slurmctld
sudo chmod -R 755  /var/spool/slurmd
sudo chmod -R 755 /var/spool/slurmctld

4、启动slurm

sudo systemctl enable slurmctld --now
sudo systemctl enable slurmd --now

5、确保节点状态初始化

sudo scontrol update NodeName=ubuntuseerver State=RESUME

6、测试是否成功

srun --partition=CPU --time=00:01:00 --ntasks=1 hostname

如果输出主机名则证明成功。

报错处理

1、如果在启动服务的时候报错，重复执行以下内容;

sudo chmod -R 755  /var/spool/slurmd
sudo chmod -R 755 /var/spool/slurmctld

然后重新启动服务

sudo systemctl restart slurmd
sudo systemctl restart slurmctld

其他报错，欢迎联系作者询问。
