This tutorial outlines the basic installation process for deploying MongoDB on Red Hat Enterprise Linux, CentOS Linux, Fedora Linux and related systems. This procedure uses .rpm packages as the basis of the installation. 10gen publishes packages of the MongoDB releases as .rpm packages for easy installation and management for users of CentOS, Fedora and Red Hat Enterprise Linux systems. While some of these distributions include their own MongoDB packages, the 10gen packages are generally more up to date.
This tutorial includes: an overview of the available packages, instructions for configuring the package manager, the process install packages from the 10gen repository, and preliminary MongoDB configuration and operation.

The 10gen repository contains four packages:
mongo-10gen
This package contains MongoDB tools from latest stable release. Install this package on all production MongoDB hosts and optionally on other systems from which you may need to administer MongoDB systems.
mongo-10gen-server
This package contains the mongod and mongos daemons from the latest stable release and associated configuration and init scripts.
mongo18-10gen
This package contains MongoDB tools from previous release. Install this package on all production MongoDB hosts and optionally on other systems from which you may need to administer MongoDB systems.
mongo18-10gen-server
This package contains the mongod and mongos daemons from previous stable release and associated configuration and init scripts.
The MongoDB tools included in the mongo-10gen packages are:
Create a /etc/yum.repos.d/10gen.repo file to hold information about your repository. If you are running a 64-bit system (recommended,) 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/x86_64
gpgcheck=0
enabled=1
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
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! Continue for configuration and start-up suggestions.
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/mongo and its log files in /var/log/mongo, and run using the mongod user account.
注解
If you change the user that runs the MongoDB process, you will need to modify the access control rights to the /var/lib/mongo and /var/log/mongo directories.
警告
With the introduction of systemd in Fedora 15, the control scripts included in the packages available in the 10gen repository are not compatible with Fedora systems. A correction is forthcoming, see SERVER-7285 for more information, and in the mean time use your own control scripts or install using the procedure outlined in 在Linux上安装.
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
Stop the mongod process by issuing the following command (as root, or with sudo):
service mongod stop
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.
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 mongodb script referenced above to derive your own mongos control script.
You must SELinux to allow MongoDB to start on Fedora systems. Administrators have two options:
Among the tools included in the mongo-10gen package, is the mongo shell. 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()
