mongodb 如何在 Centos 7 上禁用 THP
How to disable THP on Centos 7 for mongodb
我刚刚安装了 Centos 7 的全新实例
Linux version 3.10.0-229.1.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Fri Mar 27 03:04:26 UTC 2015
我安装了 mongodb 3.0,当我连接时,我收到了这条奇怪的消息:
2015-04-15T07:48:55.583+0000 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.
2015-04-15T07:48:55.583+0000 I CONTROL [initandlisten] ** We suggest setting it to 'never'
2015-04-15T07:48:55.583+0000 I CONTROL [initandlisten]
2015-04-15T07:48:55.583+0000 I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.
2015-04-15T07:48:55.583+0000 I CONTROL [initandlisten] ** We suggest setting it to 'never'
如何禁用此版本的 THP?
我尝试过但没有成功的事情
我可以禁用它运行这个命令:
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
但是当我重新启动时,问题又出现了。
我试图修改 /etc/rc.local 添加这些行:
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
exit 0
重新启动但没有结果
我也试过修改/etc/default/grub ...
我遇到了同样的问题,并通过在 /etc/rc.local
:
中写入解决了这个问题
echo never > /sys/kernel/mm/transparent_hugepage/enabled;
echo never > /sys/kernel/mm/transparent_hugepage/defrag;
我也给了/etc/rc.d/rc.local
执行权限
现在每次启动时它们都被禁用。
