1、下載MongoDB
下載Mongodb linux32二進制發行版本
http://downloads.mongodb.org/linux/mongodb-linux-i686-2.6.0.tgz
下載Mongodb linux64二進制發行版本
https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.0.tgz
2、安裝MongoDB
（1）解壓MongoDB
[root@bogon softwares]# tar -zxvf mongodb-linux-i686-2.6.0.tgz（2）修改環境變量PATH
[root@bogon mongodb-linux-i686-2.6.0]# vi /etc/profile
PATH=/softwares/mongodb-linux-i686-2.6.0/bin
[root@bogon mongodb-linux-i686-2.6.0]# source /etc/profile
（3）驗證環境變量是否生效
[root@bogon mongodb-linux-i686-2.6.0]# mongod -version
db version v2.6.0
2015-03-09T21:24:05.552+0800 git version: 1c1c76aeca21c5983dc178920f5052c298db616c
（4）創建目錄/data/db並且給予讀寫權限
[root@bogon bin]# cd /
[root@bogon /]# mkdir data
[root@bogon /]# chmod 777 data
[root@bogon /]# cd data
[root@bogon data]# mkdir db
[root@bogon data]# chmod 777 db
3、啓動mongodb
[root@bogon bin]# pwd
/softwares/mongodb-linux-i686-2.6.0/bin
[root@bogon bin]# ls
bsondump mongo mongod mongodump mongoexport mongofiles mongoimport mongooplog mongoperf mongorestore mongos mongostat mongotop
[root@bogon bin]# mongod
mongod --help for help and startup options

4、驗證mongo是否正常運行
[root@bogon /]# cd /softwares/mongodb-linux-i686-2.6.0/bin
[root@bogon bin]# mongo
bash: mongo: command not found
[root@bogon bin]# ls
bsondump mongo mongod mongodump mongoexport mongofiles mongoimport mongooplog mongoperf mongorestore mongos mongostat mongotop
[root@bogon bin]# mongo
bash: mongo: command not found
[root@bogon bin]# ./mongo
MongoDB shell version: 2.6.0

5、開放端口27017
[root@bogon bin]# vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 27017 -j ACCEPT
[root@bogon bin]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
6、查看mongodb啓動結果
[root@bogon bin]# netstat -pan|grep 27017
