---1.在proc中关闭NUMA
rpm -qa | grep numactl
yum install -y numactl
# echo 0 > /proc/sys/vm/zone_reclaim_mode
# sysctl -w vm.zone_reclaim_mode=0
---2.修改最大连接数
#vi /etc/security/limits.conf
* soft nofile 25000
* hard nofile 25000
---3.关闭防火墙
chkconfig --level 123456 iptables off
service iptables stop
---4.修改hosts
vi /etc/hosts
---5.安装mongodb
--安装openssl
yum install -y openssl-devel openssl

/******************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
