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
