本文涉及的产品
云数据库 MongoDB，通用型 2核4GB
推荐场景：
五天玩转MongoDB训练营
简介：
配置和1.8差不多，只是mongoDB2.0.0本身带来了一些新的特性，所以参数配置有点不一样。
以下是详细部署过程 : 
产品部署注意事项 : 
do not use hugepage
use ntp
use ext4/xfs
mount with option : noatime 
Do not use NUMA
DELL服务器关闭NUMA : Node Interleaving 改为Enabled则安装对称内存配置时支持内存交错。如果为 Disabled（已禁用），系统支持非一体化内存体系结构 (NUMA)（非对称）内存配置。
不关闭numa会有警告信息 :

由于使用了noauth=true,所以配置防火墙是很有必要的.以下是范例
iptables防火墙配置
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
# mongoDB:mongod,configsrv,mongos
-A RH-Firewall-1-INPUT -m iprange --src-range 10.10.10.10-10.10.10.13 -j ACCEPT
-A RH-Firewall-1-INPUT -m iprange --src-range 10.10.10.14-10.10.10.16 -j ACCEPT
# mongoDB:appserver
-A RH-Firewall-1-INPUT -m iprange --src-range xxx.xxx.xxx.xxx-xxx.xxx.xxx.xxx -p tcp -m multiport --destination-ports 6666,6669:6670 -j ACCEPT
# mongoDB:reject Port
-A RH-Firewall-1-INPUT -m state --state NEW -p tcp -m multiport --destination-ports 6666,6669:6670 -j REJECT

最后是GRIDFS的注意事项 : 
"chunks" collection should be sharded using the index "files_id: 1". The existing "files_id, n" index created by the drivers cannot be used to shard on "files_id" (this is a sharding limitation that will be fixed), so you have to create a separate index on just "files_id". The reason to use "files_id" is so that all chunks of a given file live on the same shard, which is safer and allows "filemd5" command to work (required by certain drivers).

云Mongodb Sharding如何在指定的Shard上执行Profile等命令
阿里云mongodb sharding集群处于安全的考虑用户所有的请求都是都是通过mongos来完成，而不能直连其中节点。而mongos官方目前支持的命令有限，这种情况下，用户想在某一个节点上执行一些命令，例如开启某个shard的primary节点的profile，或者某个shard的primary节点空间比较紧张执行compact命令释放空间，都无法支持；为此云mongo团队开发了一个新的命令runCommandOnShard来满足这部分需求。
