环境

  • Red Hat Enterprise Linux 7.0

问题

  • How to install cpupowerutils package in RHEL7 ?
  • When trying to run cpupower command, getting following error :

Raw

# cpupower frequency-set -f 3100
bash: cpupower: command not found...
  • Which package provides cpupowerutils package in RHEL7 ?

决议

  • /usr/bin/cpupower is provided by kernel-tools.x86_64 package in RHEL7.
  • So install this package to get /usr/bin/cpupower command in RHEL7:
# yum install kernel-tools.x86_64

      通常，command not found是系统不能找到执行命令的路径引起的，是怎么回事儿呢？拿命令ifconfig来说,如果没有 把:/sbin追加到环境变量，直接输入ifconfig命令是不能执行的，输入/sbin/ifconfig才能执行。通过whereis ifconfig可得知 ifconfig所在路径是/sbin/ifconfig,即在sbin目录下。如果环境变量中没有设置/sbin，则会显示command not found，如果不设 置环境变量并企图先进入/sbin目录再执行
