调整服务器电源性能模式
1.批量脚本
注意重启会失效,建议在带外控制台中设置
#!/bin/bash cpu0freqd=/sys/devices/system/cpu/cpu0/cpufreq /sbin/modprobe intel_pstate 2> /dev/null if [ -d ${cpu0freqd} ]; then /usr/bin/cpupower -c all frequency-set -g performance > /dev/null 2>&1 else /sbin/modprobe -r intel_pstate /sbin/modprobe acpi-cpufreq 2> /dev/null if [ -d ${cpu0freqd} ]; then /usr/bin/cpupower -c all frequency-set -g performance > /dev/null 2>&1 else /sbin/modprobe -r acpi-cpufreq 2> /dev/null fi fi1
2.通过内核修改
重启失效
sed -i 's/^GRUB_CMDLINE_LINUX.*$/GRUB_CMDLINE_LINUX=\"crashkernel=auto rhgb intel_pstate=disable quiet\"/' /etc/default/grub grub2-mkconfig -o /boot/grub2/grub.cfg
