CentOS关闭大页内存机制

centOS系统关闭方法如下:
root用户下
在vi /etc/rc.local最后添加如下代码

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
  echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
   echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
        
cat  /sys/kernel/mm/transparent_hugepage/enabled        
cat /sys/kernel/mm/transparent_hugepage/defrag  

其他系统关闭参照官方文档：
