应用介绍

可以通过多种方式来安装MLNX OFED驱动程序。 这些方法之一是使用wget获取tgz图像，将其提取并安装MLNX OFED。

1.从Mellanox网站获取MLNX_OFED版本（单击此处），或运行wget（确保特定发行版有MLNX_OFED的可用版本）。 使用以下格式：

# wget http://www.mellanox.com/downloads/ofed/MLNX_OFED-<version>/MLNX_OFED_LINUX-<version>-<distribution>-<arch>.tgz .

# wget http://www.mellanox.com/downloads/ofed/MLNX_OFED-3.4-2.0.0.0/MLNX_OFED_LINUX-3.4-2.0.0.0-rhel7.2-x86_64.tgz .

2.解压并安装。

# tar -xvf MLNX_OFED_LINUX-3.4-2.0.0.0-rhel7.2-x86_64.tgz

...

# cd MLNX_OFED_LINUX-3.4-2.0.0.0-rhel7.2-x86_64/

# ./mlnxofedinstall [options] <---- Note: Before you install MLNX_OFED review the various of installation options

<---- E.g. use --add-kernel-support flag in case the kernel is not aligned with the inbox kernel (use -h) . See below

# /etc/init.d/openibd restart

注意：
如果您使用的是其他内核，请使用安装标志--add-kernel-support。
在安装MLNX_OFED时，可能会要求您添加或删除内核模块。
例如：

./mlnxofedinstall --add-kernel-support

rpm --nosignature -e --allmatches --nodeps rdma

Note: This program will create MLNX_OFED_LINUX TGZ for rhel7.2 under /tmp/MLNX_OFED_LINUX-3.4-2.0.0.0-4.8.7 directory.

See log file /tmp/MLNX_OFED_LINUX-3.4-2.0.0.0-4.8.7/mlnx_ofed_iso.8834.log

Checking if all needed packages are installed...

Error: One or more required packages for installing OFED-internal are missing.

Please install the missing packages using your Linux distribution Package Management tool.

Run:

yum install python-devel

Failed to build MLNX_OFED_LINUX for 4.8.7

# yum remove libibumad libibverbs-devel libibverbs libmlx5 libibverbs-utils
# yum install python-devel
...

使用-h标志获取安装的所有可用选项：

# ./mlnxofedinstall -h
