Install MongoDB on FC6

http://docs.mongodb.org/manual/tutorial/install-mongodb-on-red-hat-centos-or-fedora-linux/

install MongoDB

1. configure package management system(YUM)

Create a /etc/yum.repos.d/10gen.repo file to hold information about your repository.

if you are running a 32-bit system, which isn’t recommended for production deployments, place the following configuration in /etc/yum.repos.d/10gen.repo file:

[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
gpgcheck=0
enabled=1

change [10gen] to [updates]

Install Packages¶

Issue the following command (as root or with sudo) to install the latest stable version of MongoDB and the associated tools:

yum install mongo-10gen mongo-10gen-server

When this command completes, you have successfully installed MongoDB!

when it prompts error info, you can change the "gpgcheck=1" to "gpgcheck=0" in /etc/yum.conf

Package mongo-10gen-2.4.4-mongodb_1.i686.rpm is not signed

if the previous solution does not solve the issue above, please use the rpm command as below.

rpm -ivh mongo-10gen-2.4.4-mongodb_1.i686.rpm

rpm -ivh mongo-10gen-server-2.4.4-mongodb_1.i686.rpm

Configure MongoDB¶

These packages configure MongoDB using the /etc/mongod.conf file in conjunction with the control script. You can find the init script at/etc/rc.d/init.d/mongod.

This MongoDB instance will store its data files in the /var/lib/mongoand its log files in /var/log/mongo, and run using the mongod user account.

Start MongoDB¶

Start the mongod process by issuing the following command (as root, or with sudo):

service mongod start

You can verify that the mongod process has started successfully by checking the contents of the log file at /var/log/mongo/mongod.log.

You may optionally, ensure that MongoDB will start following a system reboot, by issuing the following command (with root privileges:)

chkconfig mongod on

How to monitor the mongod process.

[root@lx updates]# netstat -lanp | grep "27017"
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 5098/mongod
unix 2 [ ACC ] STREAM LISTENING 21364 5098/mongod /tmp/mongodb-27017.sock
[root@lx updates]#

Stop MongoDB¶

Stop the mongod process by issuing the following command (as root, or with sudo):

service mongod stop

Restart MongoDB¶

You can restart the mongod process by issuing the following command (as root, or with sudo):

service mongod restart

Follow the state of this process by watching the output in the/var/log/mongo/mongod.log file to watch for errors or important messages from the server.

Control `mongos`¶

As of the current release, there are no control scripts for mongos.mongos is only used in sharding deployments and typically do not run on the same systems where mongod runs. You can use the mongodbscript referenced above to derive your own mongos control script.

SELinux Considerations¶

You must SELinux to allow MongoDB to start on Fedora systems. Administrators have two options:

enable access to the relevant ports (e.g. 27017) for SELinux. See Interfaces and Port Numbers for more information on MongoDB’s default ports.
disable SELinux entirely. This requires a system reboot and may have larger implications for your deployment.

Using MongoDB¶

Among the tools included in the mongo-10gen package, is the mongoshell. You can connect to your MongoDB instance by issuing the following command at the system prompt:

mongo

This will connect to the database running on the localhost interface by default. At the mongo prompt, issue the following two commands to insert a record in the “test” collection of the (default) “test” database and then retrieve that document.

> db.test.save( { a: 1 } )
> db.test.find()

[root@lx updates]# mongo
MongoDB shell version: 2.4.4
connecting to: test
