The MongoDB logs are displayed as follows: Warning:you is running on a NUMA machine. We suggest launching mongod like this-avoid performance problems:numactl–interleave=all Mongod [other options]

　　

2: The solution:

Add Numactl–interleave=all before the original start command

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

　　

3: Modify Kernel parameters

echo 0 >/proc/sys/vm/zone_reclaim_mode
