备注：安装可选all、hpc、basic、msm四种方式。建议使用basic标准模式。管理节点需要安装msm和basic两种模式！！！安装过程中会强制刷新HCA卡固件，非独立HCA卡请严格注意固件版本！！！
2.3 配置IB网卡IP地址
[root@node33 ~]# cat <<EOF >> /etc/sysconfig/network-scripts/ifcfg-ib0
>DEVICE=ib0
>BOOTPROTO=none
>ONBOOT=yes
>NETMASK=255.255.255.0
>IPADDR=12.12.12.3
> EOF
[root@node33 ~]#
[root@node33 ~]# cat/etc/sysconfig/network-scripts/ifcfg-ib0
DEVICE=ib0
BOOTPROTO=none
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=12.12.12.33
[root@node33 ~]#
2.4 启动IB服务
[root@node33 ~]# chkconfig--list | grep open
openibd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
opensmd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
[root@node33 ~]# /etc/init.d/openibdrestart

备注：管理节点需要先启动openibd，后启动opensmd。计算节点只需要启动openibd。配置完成后注意通过ibstat检查速率和链路状态。
3 卸载IB驱动
[root@node33 ~]#echo y | /public/ofed.uninstall.sh
This program will uninstall allMLNX_OFED_LINUX-1.5.3-4.0.42 packages on your machine.
