在安装mellanox  ufm时提示：

Restarting httpd:                                          [FAILED]

定位分析， 它程序里首先需要调用service httpd start

发现这个启动服务失败， 在shell中也确实提示这个错误：

Redirecting to /bin/systemctl start httpd.service

Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

按照提示：地址已经bind了， 最后分析发现

启动httpd服务，会启动以下配置文件，都会加载

/etc/httpd/conf

/etc/httpd/conf.d

发现里面有

ufm.conf  配置文件有错误，现这个ufm.conf配置文件在卸载老版本ufm的时候是不会删除掉，安装新的ufm的时候，直接往里面写， 导致这个ufm配置文件出错。最终直接删掉，重新安装。正确的ufm配置文件如下：
