/**
* @see --------------------------------------------------------------------------------------------------------
* 启动MongoDB
* @see 启动时,运行上面编写的startup.sh就能够了
* @see 但启动之前,有4点须要注意
* @see 1.用root启动时会有警告提示,能够为mongo单独创建一个用户来启动,以下简称"mongo用户"
* @see 2.mongo用户的[ulimit -n]和[ulimit -u]要同样,否则也会有警告提示
* @see 3.先要用root用户运行以下两个命令,否则启动后,客户端连接时会有警告提示
* @see [root@CentOS64 Jadyer]# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
* @see [root@CentOS64 Jadyer]# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
* @see 4.使用wiredTiger引擎时,须要加上directoryperdb參数,让数据库分文件夹,不然小文件太多了
* @see 比方:numactl --interleave=all /usr/local/mongodb/bin/mongod --fork --httpinterface --noauth --bind_ip=0.0.0.0 --port=27017 --storageEngine=wiredTiger --directoryperdb --dbpath=/data/mongodata/data/db1 --logpath=/data/mongodata/logs/mongodb.log --logappend
