Slurm简介
Slurm是一个开源，容错，高度可扩展的集群管理和作业调度系统，适用于各种规模的Linux集群。 Slurm不需要对其操作进行内核修改，并且相对独立。作为集群工作负载管理器，Slurm有以下特性：
1、它在一段时间内为用户分配对资源（计算节点）的独占和/或非独占访问，以便他们可以执行工作；
2、它提供了一个框架，用于在分配的节点集上启动，执行和监视工作（通常是并行作业）；
3、它通过管理待处理工作的队列来仲裁资源争用。
4、它提供作业信息统计，作业状态诊断等工具。
环境说明
系统：CentOS最小化安装；升级软件补丁，内核；关闭SELinux和防火墙。
Slurm专用账户（slurm）：Master端和Node端专用账户统一ID，建议ID号规划为200；
Slurm Master如需要支持GUI命令（sview）则需要安装GUI界面(Server with GUI)；
Slurm Maser端安装
0、安装EPEL源：yum install -y epel-release && yum makecache

2、配置主机名：hostnamectl set-hostname slurm-master #配置后重新连接即可即可生效
[root@localhost ~]# hostnamectl set-hostname slurm-master
3、配置时间服务并同步时间：CentOS7系统默认已采用Chrony时间服务
[root@slurm-master ~]# systemctl status chronyd.service

a）修改Chrony服务配置文件（/etc/chrony.conf）
a1）注释或删除”server 0.centos.pool.ntp.org iburst”等四行信息
a2）添加”server ntp.aliyun.com iburst”阿里云官方时间效验地址或其它自定义时间效验服务器地址
a1）注释或删除”server 0.centos.pool.ntp.org iburst”等四行信息
a2）添加”server ntp.aliyun.com iburst”阿里云官方时间效验地址或其它自定义时间效验服务器地址
# These servers were defined in the installation: #server 0.centos.pool.ntp.org iburst #server 1.centos.pool.ntp.org iburst #server 2.centos.pool.ntp.org iburst #server 3.centos.pool.ntp.org iburst server ntp.aliyun.com iburst
a3）取消注释”#allow 192.168.0.0/16″并按需修改为Slurm Node的IP段
# Allow NTP client access from local network. allow 192.168.80.0/24
a4）重启Chrony服务（systemctl restart chronyd.service）并查验（chronyc sources）
[root@slurm-master ~]# systemctl restart chronyd.service [root@slurm-master ~]# chronyc sources 210 Number of sources = 1 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* 203.107.6.88 2 6 17 9 -288us[-1252us] +/- 16ms
4、部署Munge：目前在线安装的Munge版本为0.5.11
a）安装Munge程序：yum install -y munge munge-libs munge-devel
[root@slurm-master ~]# yum install -y munge munge-libs munge-devel Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Resolving Dependencies --> Running transaction check ---> Package munge.x86_64 0:0.5.11-3.el7 will be installed ---> Package munge-devel.x86_64 0:0.5.11-3.el7 will be installed ---> Package munge-libs.x86_64 0:0.5.11-3.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================== Package Arch Version Repository Size ========================================================================================================================================================== Installing: munge x86_64 0.5.11-3.el7 epel 95 k munge-devel x86_64 0.5.11-3.el7 epel 22 k munge-libs x86_64 0.5.11-3.el7 epel 37 k Transaction Summary ========================================================================================================================================================== Install 3 Packages Total download size: 154 k Installed size: 341 k Downloading packages: (1/3): munge-devel-0.5.11-3.el7.x86_64.rpm | 22 kB 00:00:00 (2/3): munge-0.5.11-3.el7.x86_64.rpm | 95 kB 00:00:00 (3/3): munge-libs-0.5.11-3.el7.x86_64.rpm | 37 kB 00:00:00 ---------------------------------------------------------------------------------------------------------------------------------------------------------- Total 529 kB/s | 154 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : munge-libs-0.5.11-3.el7.x86_64 1/3 Installing : munge-0.5.11-3.el7.x86_64 2/3 Installing : munge-devel-0.5.11-3.el7.x86_64 3/3 Verifying : munge-0.5.11-3.el7.x86_64 1/3 Verifying : munge-devel-0.5.11-3.el7.x86_64 2/3 Verifying : munge-libs-0.5.11-3.el7.x86_64 3/3 Installed: munge.x86_64 0:0.5.11-3.el7 munge-devel.x86_64 0:0.5.11-3.el7 munge-libs.x86_64 0:0.5.11-3.el7 Complete!
b）设置相关目录文件指定权限：chmod -R 0700 /etc/munge /var/log/munge && chmod -R 0711 /var/lib/munge && chmod -R 0755 /var/run/munge
[root@slurm-master ~]# chmod -R 0700 /etc/munge /var/log/munge && chmod -R 0711 /var/lib/munge && chmod -R 0755 /var/run/munge
c）Munge秘钥文件属性确保宿主和宿组为munge，文件权限确保为0600；
c1）生成Munge秘钥文件：以下两种方式任选一种即可，文件存储在/etc/munge目录中；后期相关的Slurm节点都需同步此文件
等待一些随机数据（推荐给偏执狂）：dd if=/dev/random bs=1 count=1024 >/etc/munge/munge.key
抓取一些伪随机数据（建议不耐烦）：dd if=/dev/urandom bs=1 count=1024 >/etc/munge/munge.key
c1）生成Munge秘钥文件：以下两种方式任选一种即可，文件存储在/etc/munge目录中；后期相关的Slurm节点都需同步此文件
等待一些随机数据（推荐给偏执狂）：dd if=/dev/random bs=1 count=1024 >/etc/munge/munge.key
抓取一些伪随机数据（建议不耐烦）：dd if=/dev/urandom bs=1 count=1024 >/etc/munge/munge.key
[root@slurm-master ~]# dd if=/dev/urandom bs=1 count=1024 >/etc/munge/munge.key 1024+0 records in 1024+0 records out 1024 bytes (1.0 kB) copied, 0.00257561 s, 398 kB/s
c2）授权Munge秘钥文件：chown munge:munge /etc/munge/munge.key && chmod 0600 /etc/munge/munge.key
chown munge:munge /etc/munge/munge.key && chmod 0600 /etc/munge/munge.key
c3）启动Munge服务并配置服务自启动：systemctl start munge.service && systemctl enable munge.service
[root@slurm-master ~]# systemctl start munge.service && systemctl enable munge.service Created symlink from /etc/systemd/system/multi-user.target.wants/munge.service to /usr/lib/systemd/system/munge.service.
c4）本机验证：munge -n | unmunge
[root@slurm-master ~]# munge -n | unmunge STATUS: Success (0) ENCODE_HOST: slurm-master (192.168.80.250) ENCODE_TIME: 2020-09-25 13:29:06 +0800 (1601011746) DECODE_TIME: 2020-09-25 13:29:06 +0800 (1601011746) TTL: 300 CIPHER: aes128 (4) MAC: sha1 (3) ZIP: none (0) UID: root (0) GID: root (0) LENGTH: 0

NodeName=slurm-node[1-32]：#配置节点主机名；编号格式：独立的”NodeName1″、连续的(含不连续的)”NodeName[2-3,4,6,7-10]”；
NodeAddr=x.x.x.x：#配置对应节点的IPv4地址；当集群环境有DNS服务时此项可不配置；
#NodeName=linux[1-32] Procs=1 State=UNKNOWN NodeName=slurm-node[1-32] NodeAddr=192.168.80.251 Procs=1 State=UNKNOWN
PartitionName=debug Nodes=ALL Default=YES MaxTime=INFINITE State=UP #默认项，建议直接注释保留，另起一行配置分区队列信息（Slurm Master控制端无需配置）；
说明：
PartitionName=debug：#计算分区队列；默认”debug”；可按需自定义；
Nodes=ALL：#表示分区队列内包含的计算节点数量；默认”ALL”；可按需自定义，节点编号格式：独立的”NodeName1″、连续的(含不连续的)”NodeName[2-3,4,6,7-10]”；
Default=YES：#默认计算队列分区；表示Slurm在提交任务时不指定分区队列时默认使用的计算分区队列；多分区队列模式下只能一个分区配置YES模式；
MaxTime=INFINITE：#计算任务的最大时间限制(默认单位为分钟)，默认”INFINITE”无限；保持默认即可；
State=UP：#分区队列状态，默认”UP”有效；保持默认即可；
#PartitionName=debug Nodes=ALL Default=YES MaxTime=INFINITE State=UP PartitionName=debug Nodes=slrum-node[1-32] Default=YES MaxTime=INFINITE State=UP
e3）创建配套目录及授权配套目录：mkdir /var/spool/slurm && chown slurm:slurm /var/spool/slurm
[root@slurm-master slurm]# mkdir /var/spool/slurm && chown slurm:slurm /var/spool/slurm
e4）启动Slurm Master服务并设置服务自启动：systemctl start slurmctld.service && systemctl enable slurmctld.service
[root@slurm-master slurm]# systemctl start slurmctld.service && systemctl enable slurmctld.service Created symlink from /etc/systemd/system/multi-user.target.wants/slurmctld.service to /usr/lib/systemd/system/slurmctld.service.
[root@slurm-master slurm]# systemctl status slurmctld.service

到此Slurm的Master端安装部署基本完成，可以使用sinfo命令或sview命令来查看及管理
