MongoDB 在 VPS 上不稳定，经常崩溃，该如何解决？

一不小心就kill了，启动时有如下信息：

** WARNING: You are running in OpenVZ which can cause issues on versions of RHEL older than RHEL6.

** WARNING: /proc/sys/vm/zone_reclaim_mode is 1
** We suggest setting it to 0
** http://www.kernel.org/doc/Documentation/sysctl/vm.txt

不是写了解决办法了么

@beordle
echo 0 > /proc/sys/vm/zone_reclaim_mode
-bash: /proc/sys/vm/zone_reclaim_mode: Permission denied

I am root user.

OpenVZ没权限么..他说要你换RHEL6以上版本.不过我估计换了也麻烦. 最简单的方法是换KVM的 DO也不贵啊..
