/******************解决办法
不重启服务器的情况下解决办法,在Linux下执行：
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
服务器重启后立即生效办法：
# vi /etc/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi

----1.6正常停止方法:
# ps aux | grep mongod
root 3765 1.9 0.1 500832 58224 ? Sl 12:38 0:02 /data/mongodb/apps/mongodb/bin/mongod --config /data/mongodb/apps/mongodb/bin/mongodb.conf
# kill -2 3765
或
# /data/mongodb/apps/mongodb/bin/mongo -port 27107
> use admin;
> db.shutdownServer();
----1.7 开机自动启动mongodb
# vi /etc/rc.d/rc.local
#启动mongodb
rm -rf /data/mongodb/db/mongod.lock
numactl --interleave=all /data/mongodb/apps/mongodb/bin/mongod --config /data/mongodb/apps/mongodb/bin/mongodb.conf --replSet wind
#hugepage
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
说明：启动时必须加numactl --interleave=all
