下载地址：

解压命令：tar zxf mongodb-linux-i686-2.6.0.tgz

存放目录：/usr/local/mongodb

数据目录：/mongodb/data/

日志文件：/mongodb/dblogs

没有具体的安装步骤，解压到存放目录就好了。

mongodb的bin目录下添加数据和日志存放路径：./mongod --dbpath=/usr/local/mongodb/data/ --logpath=/usr/local/mongodb/dblogs --fork

pkill mongod    杀掉mongod进程，不能用kill -9杀掉mongod进程,否则就不能再启动

或者killall mongod
