echo Never >/sys/kernel/mm/transparent_hugepage/enabled

Write rc.local at the same time

There are three ways to modify kernel parameters, but to have root privileges:

(1) Edit/etc/sysctl.conf, change Vm.overcommit_memory=1, and sysctl-p make the configuration file effective

(2) Sysctl Vm.overcommit_memory=1

(3) echo 1 >/proc/sys/vm/overcommit_memory
