mongodb 3.2.7版本 的分片集群安装demo

下面的作法，是在一台机器上，搭建一个mongodb分片集群。所有的mongod，mongos实例均运行在一台机器上，原因是目前手头没有多余的机器，所以只能在一台服务器上，共运行12个mongod实例(9个用于副本集，3个用于配置)，1个mongos实例，为了防止端口、路径、文件冲突所以进行了细心的设计。另外也只是学习mongodb的分片集群的安装，所以也就没有搞太多的机器。

操作步骤
cd /home/deploy/test/mongodb
这个目录为mongodb的安装目录(关于mongodb的安装，就不详述了),在该目录下建如下目录
mkdir data
cd data
#shard1目录
mkdir db1-1
mkdir db1-2
mkdir db1-3
#shard2目录
mkdir db2-1
mkdir db2-2
mkdir db2-3
#shard3目录
mkdir db3-1
mkdir db3-2
mkdir db3-3
#log目录
mkdir log
#配置文件目录
mkdir configdb1
mkdir configdb2
mkdir configdb3
