./bin/mongod --port 33334 --fork --logpath data/log/mongodb.log --dbpath data/db
启动相关参数说明如下：

--port 启动端口号

--fork 以守护进行方式启动

--logpath mongodb 日志输出路径

--dbpath mongodb 数据文件路径

其他选项可以执行命令查看：   ./bin/mongod --help

启动脚本

things from mongod.conf get there by mongod reading it
NOTE: if you change any OPTIONS here,you get what you pay for:
this script assumes all options are in the config file.

OPTIONS=" -f $CONFIGFILE"

SYSCONFIG="/etc/sysconfig/mongod"
FIXME: 1.9.x has a --shutdown flag that parses the config file and
shuts down the correct running pid,but that's unavailable in 1.8
for now.  This can go away when this script stops supporting 1.8.
