MongoDB numa系列问题二：WARNING: You are running on a NUMA machine.

1：Mongod日志warning：

mongodb日志显示如下:

WARNING: You are running on a NUMA machine.

We suggest launching mongod like this to avoid performance problems:

numactl –interleave=all mongod [other options]

2：解决方案：

在原启动命令前面加numactl –interleave=all

#numactl --interleave=all mongod --config /mongodb/mongod.conf

3：修改内核参数

echo 0 > /proc/sys/vm/zone_reclaim_mode
