Hadoop Mong DB CentOS 6 installs MongoDB and server-side configuration with Yum

There are many ways to install MongoDB, you can install the source code, and you can use the Yum source installation method in CentOS. Since MongoDB is updated more quickly, I prefer to use the Yum source installation method. The installation steps under 64-bit CentOS are as follows:

1. Preparatory work

Run the Yum command to view MongoDB package information [email protected]~]# yum Info Mongo-10gen

(Hint that there is no matching information) that the Yum source in your CentOS system does not contain MONGODB resources, so you need to add the Yum source before installing MongoDB with the Yum command, which means adding *.repo in the/etc/yum.repos.d/directory Yum Source configuration file

2, Vi/etc/yum.repos.d/10gen.repo, enter the following statement:

[10gen]

Name=10gen Repository

Baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64

Gpgcheck=0

After you have configured the Yum source, you can query MongoDB-related information if the configuration correctly executes the following command:

3. Installing MongoDB server side and client tools
[email protected] geffzhang]# Yum install Mongo-10gen-server

[email protected] geffzhang]# Yum install Mongo-10gen

4. Start MongoDB

Service Mongod Start

Updated later, stop MongoDB, execute yum update Mongo-10gen mongo-10gen-server.
