–查看当前透明大页情况
[root@localhost ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
–查看当前numa情况
[root@localhost ~]# dmesg | grep -i numa

–关闭透明大页和numa
–编辑grub文件，添加：transparent_hugepage=never numa=off
[root@localhost ~]# vi /etc/default/grub
[root@localhost ~]# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX
GRUB_CMDLINE_LINUX=“resume=/dev/mapper/uos-swap rd.lvm.lv=uos/root rd.lvm.lv=uos/swap rhgb quiet elevator=mq-deadline transparent_hugepage=never numa=off”
