Mongodb is used for many projects now, it is quite fast. I given full detailed information about How to install Mongodb on linux box. Before installing the Mongodb on linux box you need to install following packages on box.

How to install Mongodb on linux

[root@sonyk-pc Download]# sudo yum -y install git tcsh scons gcc-c++ glibc-devel
[root@sonyk-pc Download]# sudo yum -y install boost-devel pcre-devel js-devel readline-devel
[root@sonyk-pc Download]# sudo yum -y install boost-devel-static readline-static ncurses-static

For 32bit user use following command

[root@sonyk-pc Download]# wget http://fastdl.mongodb.org/linux/mongodb-linux-i686-1.6.2.tgz

For 64bit use following command

[root@sonyk-pc Download]# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.6.2.tgz
[root@sonyk-pc Download]# tar xzf mongodb-linux-i686-1.6.2.tgz
[root@sonyk-pc Download]#  cd mongodb-linux-i686-1.6.2

Mongo stores database in data/db folder. so we need to create those folder using following command.

[root@sonyk-pc mongodb-linux-i686-1.6.2]# sudo mkdir -p /data/db/
[root@sonyk-pc mongodb-linux-i686-1.6.2]# sudo chown `id -u` /data/db

[root@sonyk-pc mongodb-linux-i686-1.6.2]# ./bin/mongod
./bin/mongod --help for help and startup options
Thu Sep  9 13:10:55 MongoDB starting : pid=22159 port=27017 dbpath=/data/db/ 32-bit
** NOTE: when using MongoDB 32 bit, you are limited to about 2 gigabytes of data
**       see http://blog.mongodb.org/post/137788967/32-bit-limitations

If you want to create mongodb service in linux then use following steps:

[root@sonyk-pc Download]# wget http://fastdl.mongodb.org/linux/mongodb-linux-i686-1.6.2.tgz
[root@sonyk-pc Download]# tar xzf http://fastdl.mongodb.org/linux/mongodb-linux-i686-1.6.2.tgz
[root@sonyk-pc Download]# mv mongodb-linux-i686-1.6.2 /opt/mongodb
[root@sonyk-pc Download]# mkdir -p /srv/db/mongodb
[root@sonyk-pc Download]# touch /srv/db/mongodb.log
[root@sonyk-pc Download]# mkdir /opt/bin/
[root@sonyk-pc Download]# mkdir /opt/config/

create the File: /opt/bin/mongodb-stop
Put following code in that file:

#!/bin/bash
pid=`ps -o pid,command ax | grep mongod | awk '!/awk/ && !/grep/ {print $1}'`;
if [ "${pid}" != "" ]; then
kill -2 ${pid};
fi

create the File: /opt/bin/mongodb-start
Put following code in that file:

#!/bin/sh
/opt/mongodb/bin/mongod --config /opt/config/mongodb \
## --upgrade \ ##runs a database upgrade option if needed \

File: /opt/config/mongodb
Put following code in that file:

# Configuration Options for MongoDB
#
# For More Information, Consider:
# - Configuration Parameters: http://www.mongodb.org/display/DOCS/Command+Line+Parameters
# - File Based Configuration: http://www.mongodb.org/display/DOCS/File+Based+Configuration
dbpath = /srv/db/mongodb
logpath = /srv/db/mongodb.log
logappend = true
bind_ip = 127.0.0.1
port = 27017
fork = true
auth = true
# noauth = true

Do that file as linux executable
chmod +x /opt/bin/mongodb-start
chmod +x /opt/bin/mongodb-stop
We’ve also created a very basic “init script” as a wrapper around the mongodb-start and mongo-stop scripts described above. You will still need to modify and manage the configuration of your MongoDB server in the files above. This script only provides a means for ensuring that MongoDB will start at boot. Issue the following commands:
wget http://library.linode.com/databases/mongodb/reference/init-rpm.sh
mv init-rpm.sh /etc/rc.d/init.d/mongodb
chmod +x /etc/rc.d/init.d/mongodb /etc/init.d/mongodb
chkconfig –add mongodb
chkconfig –level 35 mongodb on
You will also need to create a user and group for mongodb; issue the following command:

useradd -M -r --home-dir /opt/mongodb mongodb

Now issue the following command to ensure that the MongoDB user you just created will have access to all required files in the /srv/db/ hierarchy:
chown mongodb:mongodb -R /srv/db/
To start and stop MongoDB using the init script, issue the appropriate command from the following:
/etc/init.d/mongodb start
/etc/init.d/mongodb stop
