说明：
一. 集群环境搭建分为：【NTP】、【MUNGE】、【Slurm】
网络拓扑
计算机名称 IP地址 角色
master 192.168.114.242 管理节点（master）
compute1 192.168.114.243 计算节点（compute1）
compute2 192.168.114.244 计算节点（compute1）
集群节点基本操作
关闭SELinux
# vi /etc/sysconfig/selinux #注释：修改内容
SELINUX=disabled
关闭 Firewall
# systemctl stop firewalld.service
# systemctl disable firewalld.service
#vi /etc/hosts #注释：增加内容
192.168.114.242 slurm-master
192.168.114.243 slurm-compute1
192.168.114.244 slurm-compute2
# reboot
创建 munge 和 slurm 用户
# export MUNGEUSER=1001 && groupadd -g $MUNGEUSER munge
# useradd -m -c "MUNGE Uid 'N' Gid Emporium" -d /var/lib/munge -u $MUNGEUSER -g munge -s /sbin/nologin munge
# export SLURMUSER=1002 && groupadd -g $SLURMUSER slurm
# useradd -m -c "SLURM workload manager" -d /var/lib/slurm -u $SLURMUSER -g slurm -s /bin/bash slurm
安装依赖软件（NTP、MUNGE、Slurm 全部软件包安装）
# yum install -y epel-release axel yum-axelget

集群节点安装 NTP
# systemctl enable ntpd.service
# ntpdate pool.ntp.org
# systemctl start ntpd
# rngd -r /dev/urandom
管理节点（master）安装 MUNGE
# /usr/sbin/create-munge-key -r
# dd if=/dev/urandom bs=1 count=1024 > /etc/munge/munge.key
# chown munge: /etc/munge/munge.key && chmod 400 /etc/munge/munge.key
# scp -p /etc/munge/munge.key root@192.168.114.243:/etc/munge #注释：同步到计算节点
# scp -p /etc/munge/munge.key root@192.168.114.244:/etc/munge #注释：同步到计算节点
集群节点启动 MUNGE 服务
# chown -R munge: /etc/munge/ /var/log/munge/ && chmod 0700 /etc/munge/ /var/log/munge/
# systemctl enable munge
# systemctl start munge
# systemctl status munge
集群节点安装 Slurm
# cd /usr/local
# rpmbuild -ta --with mysql slurm-20.11.2.tar.bz2 #注释：编译Slurm
# cd /root/rpmbuild/RPMS/x86_64
# yum localinstall slurm-*.rpm -y #注释：安装Slurm
管理节点（master）配置 Slurm

# mysql -u root -p # 登录 Msql
# set global validate_password_policy=LOW;
# set global validate_password_length=6;
# ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
创建slurm的数据库
# create database slurm_acct_db;
# create database slurm_jobcomp_db;
设置主机访问虚拟机 mysql，如果不是在虚拟机中运行，请忽略
# use mysql;
# select host from user where user='root';
# update user set host = '%' where user = 'root';
# select host from user where user='root';
# flush privileges;
管理节点（master）启动 Slurm 服务
# systemctl enable slurmdbd.service
# systemctl start slurmdbd.service
# systemctl status slurmdbd.service
# systemctl enable slurmctld.service
# systemctl start slurmctld.service
# systemctl status slurmctld.service
计算节点（compute）启动 Slurm 服务
