CentOS6.5中安装MongoDB

1、下载MongoDB

下载Mongodb linux32二进制发行版本

http://downloads.mongodb.org/linux/mongodb-linux-i686-2.6.0.tgz

下载Mongodb linux64二进制发行版本

https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.0.tgz

2、安装MongoDB

（1）解压MongoDB

[root@bogon softwares]# tar -zxvf mongodb-linux-i686-2.6.0.tgz

（2）修改环境变量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）验证环境变量是否生效

[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）创建目录/data/db并且给予读写权限

[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、启动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

4、验证mongo是否正常运行

[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

5、开放端口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启动结果

[root@bogon bin]# netstat -pan|grep 27017
