进入到mongodb下面的bin里面查看mongodb帮助文档
./mongod -h
找到参数
--fork --dbpath arg --logpath arg --nohttpinterface
--dbpath=/usr/local/mongodb/data/ 用于指定存放的mongodb数据库
--fork 是后台执行，不然一直在前台
--logpath=/usr/local/mongodb/logs 用于指定mongodb的日志记录文件
启动数据库
sudo ./mongod --dbpath=/usr/local/mongo/mongodb-linux-x86_64-ubuntu1404-4.0.5/data/ --logpath=/usr/local/mongo/mongodb-linux-x86_64-ubuntu1404-4.0.5/logs
启动后即可通过mongo命令进入数据库。
