2)下载好后：

rpm -ivh *.rpm  --force --nodeps

3) 关掉防火墙与selinux

vi /etc/selinux/config

SELINUX=disabled

systemctl disable firewalld.service

4) vi /etc/modprobe.d/lustre.conf

加入：

options lnet networks="o2ib0(ib0),tcp0(ens41f0)"

5）设置ib的IP地址

vi /etc/sysconfig/network-scripts/ifcfg-ib0

CONNECTED_MODE=no

TYPE=InfiniBand

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

IPV6_ADDR_GEN_MODE=stable-privacy

NAME=ib0

DEVICE=ib0

ONBOOT=yes

IPADDR=11.11.1.26

PREFIX=24

IPV6_PRIVACY=no

6) vi /etc/rc.local

modprobe lnet

modprobe lustre

lnetctl set discovery 0

mount -t lustre 11.11.1.101@o2ib0:/lustre /lustre

umount -l /lustre

mount -t nfs mu01:/opt /opt

mount -t lustre 11.11.1.101@o2ib0:/lustre /lustre

7) mkdir /lustre

8) reboot

启动后执行 /etc/rc.local 第一次挂载较慢，可以ctrl+c，多试几次就好了。
