新到了一批机器，检查发现CPU频率一直比较低，应该是锁频了，这里记录下解锁的过程

#安装工具包 yum install cpupowerutils -y #查看当前模式 cpupower frequency-info #检查当前频率 cat /proc/cpuinfo |grep MHz #修改模式 cpupower frequency-set -g performance #检查修改后频率 cat /proc/cpuinfo |grep MHz

cpupower frequency-info可以看到当前CPU的频率

[root@node18 ~]# cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 1000 MHz - 3.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1000 MHz and 3.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.01 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes

current policy：内可以看到目前的运行模式

模式说明 performance 运行于最大频率 powersave 运行于最小频率 userspace 运行于用户指定的频率 ondemand 按需快速动态调整CPU频率，一有cpu计算量的任务，就会立即达到最大频率运行，空闲时间增加就降低频率 conservative 按需快速动态调整CPU频率，比 ondemand 的调整更保守 schedutil 基于调度程序调整 CPU 频率
