[root@localhost ~]# cd /mnt/
[root@localhost mnt]# ls
common_installers.pl create_mlnx_ofed_installers.pl docs LICENSE mlnxofedinstall RPMS uninstall.sh
common.pl distro is_kmp_compat.sh mlnx_add_kernel_support.sh RPM-GPG-KEY-Mellanox src

2.3 执行安装脚本
[root@localhost mnt]#./mlnxofedinstall --skip-distro-check --without-fw-update
Logs dir: /tmp/MLNX_OFED_LINUX.7290.logs
General log file: /tmp/MLNX_OFED_LINUX.7290.logs/general.log
This program will install the MLNX_OFED_LINUX package on your machine.
Note that all other Mellanox, OEM, OFED, RDMA or Distribution IB packages will be removed.
Those packages are removed due to conflicts with MLNX_OFED_LINUX, do not reinstall them.

You may need to update your initramfs before next boot. To do that, run:

三、升级过内核驱动安装步骤
​ 如果升级过内核的话，直接执行安装脚本是不可行的，因为里面的rpm包是在安装完毕的默认内核版本上（kernel-4.19.90-24.4.v2101.ky10.aarch64）编译的
下面示例中我将内核升级到了外网源中25.29版本：kernel-4.19.90-25.29.v2101.ky10.aarch64
rpm -qa | grep kernel-4.19
kernel-4.19.90-24.4.v2101.ky10.aarch64
kernel-4.19.90-25.29.v2101.ky10.aarch64

uname -r
kernel-4.19.90-25.29.v2101.ky10.aarch64

3.1 安装依赖包
yum install tcsh rpm-build elfutils-devel createrepo -y

3.2 挂载官网下载的iso驱动文件到/mnt目录
[root@localhost ~]# mount MLNX_OFED_LINUX-5.4-3.7.5.0-kylin10sp2-aarch64.iso /mnt
mount: /mnt: WARNING: source write-protected, mounted read-only.
[root@localhost ~]# cd /mnt/
[root@localhost mnt]# ls
common_installers.pl create_mlnx_ofed_installers.pl docs LICENSE mlnxofedinstall RPMS uninstall.sh
common.pl distro is_kmp_compat.sh mlnx_add_kernel_support.sh RPM-GPG-KEY-Mellanox src

3.3 直接执行安装脚本，会有报错

以上报错：已安装kernel-4.19.90-25.29.v2101.ky10.aarch64内核，MLNX_OFED_LINUX没有可用于该内核的驱动程序。
问题原因：1.系统版本不一致；2.内核版本不支持
3.4 重新编译驱动文件并安装
镜像中有提供编译适合当前系统内核版本的驱动的sh脚本（mlnx_add_kernel_support.sh）
执行./mlnx_add_kernel_support.sh -m ./命令添加针对当前内核版本的驱动；
./mlnx_add_kernel_support.sh -m ./

编译完成后的驱动默认存放在/tmp目录，编译完成后进入到/tmp目录，执行tar命令进行解压，在执行./mlnxofedinstall --skip-distro-check --without-fw-update命令进行驱动安装
四、安装过程中遇到的问题汇总
4.1 tmp目录过小
编译生成的文件和日志在/tmp目录下产生，/tmp目录过小的话需要执行mount命令重新将tmpfs进行挂载。如果/tmp目录在系统安装过程中有分配具体的分区挂载到/tmp目录，空间不够则需要进行扩容
mount -o remount,size=4G tmpfs /tmp

4.2 参数注解
执行./mlnxofedinstall --skip-distro-check --without-fw-update进行驱动安装
--skip-distro-check跳过distro匹配检查
--without-fw-update跳过固件升级
