概述
利用OpenHPC搭建CentoS7.X集群
- 主节点系统（CentOS-7.7）配置
- 管理节warewulf点配置
- 配置计算节点
- 创建计算节点启动镜像
- 组装Virtual Node File System (VNFS) 镜像
- 添加节点
- 计算节点完成安装后设置
目前搭建HPC的开源工具主要有RocksCluster, Xcat，Open-HPC。其中OpenHPC 是Linux基金开源的超算项目，致力于为高性能计算构建一个开源框架，适应学术研究的需求，为 HPC 环境创建一个开源框架，降低成本。
本次采用虚拟机实验，没有Infiniband,故先不介绍Infiniband的配置

- ohpc-base,warewulf,pbs ；
安装open-HPC yum源 ohpc-release；
[root@server ~]#yum install http://build.openhpc.community/OpenHPC:/1.3/CentOS_7/x86_64/ohpc-release-1.3-1.el7.x86_64.rpm
[root@server ~]#yum -y install ohpc-base
[root@server ~]#yum -y install ohpc-warewulf
[root@server ~]#yum -y install pbspro-server-ohpc
管理节warewulf点配置
将/etc/warewulf/provision.conf文件中的 network device = eth1 改成内网网卡ens33
[root@server ~]# vi /etc/warewulf/provision.conf
# What is the default network device that the master will use to
# communicate with the nodes?
network device = ens33
# Which DHCP server implementation should be used?
dhcp server = isc
# What is the TFTP root directory that should be used to store the
# network boot images? By default Warewulf will try and find the
# proper directory. Just add this if it can't locate it.
#tftpdir = /var/lib/tftpboot
# Automatically generate and manage a dynamnic_host virtual file
# object in the datastore? This is useful for provisioning this
# out to nodes so they always have a current /etc/hosts file.
generate dynamic_hosts = yes
# Should we manage and overwrite the local hostfile file on this
# system? This will cause all node entries to be added
# automatically to /etc/hosts.
update hostfile = yes
# If no cluster/domain is set on a node, should we add 'localdomain'
# as the default domain
use localdomain = yes
# The default kernel arguments to pass to the nodes boot kernel
default kargs = "net.ifnames=0 biosdevname=0 quiet"
编辑/etc/xinetd.d/tftp文件, 将disable = yes改为 disable = no
[root@server ~]# vi /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer
# protocol. The tftp protocol is often used to boot diskless
# workstations, download configuration files to network-aware printers,
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
启动xinetd,mariadb,http服务
[root@server ~]# systemctl restart xinetd.service
[root@server ~]# systemctl enable xinetd.service
[root@server ~]# systemctl restart mariadb.service
[root@server ~]# systemctl enable mariadb.service
[root@server ~]# systemctl enable httpd.service

[root@server ~]# cp /opt/ohpc/pub/examples/ganglia/gmond.conf /etc/ganglia/gmond.conf
[root@server ~]# vi /etc/ganglia/gmond.conf
/* The host section describes attributes of the host, like the location */
host {
location = "unspecified"
}
/* Feel free to specify as many udp_send_channels as you like. Gmond
used to only support having a single channel */
udp_send_channel {
#bind_hostname = yes # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# that resolves to the machine's hostname. Without
# this, the metrics may appear to come from any
# interface and the DNS names associated with
# those IPs will be used to create the RRDs.
host = server !!!修改成当前主机名
port = 8649
ttl = 1
}
[root@server ~]# cp /etc/ganglia/gmond.conf $CHROOT/etc/ganglia/gmond.conf
[root@server ~]# echo "gridname MyCluster" >> /etc/ganglia/gmetad.conf
# 设置ganglia服务开机启动

[root@server ~]# systemctl start gmetad.service
[root@server ~]# chroot $CHROOT systemctl enable gmond.service
#重启HTTP服务
[root@server ~]# systemctl try-restart httpd.service
在浏览器中输入http://192.168.130.100/ganglia就可以查看ganglia监控界面。

sleep 1s
wwsh dhcp update
wwsh pxe update
计算节点完成安装后设置
- 计算节点安装成功后设置从本地硬盘启动
[root@server ~]# wwsh provision set --bootlocal=normal "node[1-5]"
