~$ cd /sys/kernel/mm/transparent_hugepage/
/sys/kernel/mm/transparent_hugepage$ ls
defrag  enabled  khugepaged
/sys/kernel/mm/transparent_hugepage$ cat enabled 
always [madvise] never
/sys/kernel/mm/transparent_hugepage$ sudo echo always > enabled 
-bash: enabled: Permission denied
/sys/kernel/mm/transparent_hugepage$ sudo ls
[sudo] password for <...>: 
defrag  enabled  khugepaged
/sys/kernel/mm/transparent_hugepage$ sudo ls
defrag  enabled  khugepaged
/sys/kernel/mm/transparent_hugepage$ sudo echo always > enabled 
-bash: enabled: Permission denied
/sys/kernel/mm/transparent_hugepage$ cat enabled

添加以下内容：

transparent_hugepage=always

到您的 GRUB_CMDLINE_LINUX_DEFAULT：

/etc/default/grub

并做一个：

update-grub

应该做的伎俩。

将此添加到您的 /etc/rc.local：
