Simple and practical MongoDB installation Tutorial: Use yum in centos to install MongoDB and server configuration details

Reprinted: View Original

 

I. preparations:

 

Run the yum command to view the MongoDB package information.

[Root @ VM ~] # Yum info mongo-10gen
(No matching information is displayed ,)

It indicates that the yum source in your centos system does not contain MongoDB resources. Therefore, you need to add the yum source before using the yum command to install MongoDB, that is, in/etc/yum. repos. d/Add * to the directory *. repo Yum source configuration file. The following are the configuration content of MongoDB Yum source for 64-bit centos and 32-bit different systems:

We will name this file here:/Etc/yum. Repos. d/10gen. Repo

For 64-bit Yum source Configuration:

VI/etc/yum. Repos. d/10gen. Repo

[10gen]name=10gen Repositorybaseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64gpgcheck=0

For 32-bitYum source configuration:

VI/etc/yum. Repos. d/10gen. Repo

[10gen]name=10gen Repositorybaseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686gpgcheck=0

Select the corresponding configuration content based on your system

Check whether the system is 32-bit or 64-bit:

$ Uname-

If x86_64 is contained, it indicates that it is 64-bit, for example, myCentos6.0 64bitAfter the system executes this command, it displays:

Linux vm.centos6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

 

After configuring the yum source, if the configuration is correct, execute the following command to query MongoDB-related information:

View MongoDB server package information

[Root @ VM ~] # Yum info mongo-10gen-server * (Omitted multi-row unimportant information) * Available packagesname: mongo-10gen-serverArch: x86_64version: 1.8.2release: mongodb_1size: 4.7 mrepo: 10 gensummary:Mongo server, sharding server, and support scriptsURL: http://www.mongodb.orgLicense: agpl 3.0 Description: Mongo (from "Humongous") is a schema-free document-oriented: database.: this package provides the Mongo server software, Mongo sharding: Server softwware, default configuration files, and init. d scripts. [root @ VM ~] #

 

View client tool information

[Root @ VM ~] # Yum info mongo-10genLoaded plugins: fastestmirror ** (omitting multiline unimportant information) ** installed packagesname: mongo-10genArch: x86_64version: 1.8.2release: mongodb_1size: 55 mrepo: 10 gensummary:Mongo client shell and toolsURL: http://www.mongodb.orgLicense: agpl 3.0 Description: Mongo (from "Humongous") is a schema-free document-oriented: database. it features dynamic profileable queries, full indexing,: Replication and fail-over support, efficient storage of large: binary data objects, and auto-sharding.: this package provides the Mongo shell, import/export tools, and: other client utilities. [root @ VM ~] #

 

Ii. Install MongoDB server and client tools

1. Install the server:

[Root @ VM ~] # Yum install mongo-10gen-server [root @ VM ~] # Ls/usr/bin/Mongo(Tab key)Mongo mongod mongodump unzip Export Program Files Export Import mongorestore mongos unzip stat ----------------------------------------------- these are MongoDB Program Files

Because the mongo-10gen-server package depends on the mongo-10gen, there is no need to install the client toolkit mongo-10gen separately after the server is installed.

 

2. Install the client separately:

[root@vm ~]# yum install mongo-10gen

 

3. Check

[root@vm ~]# /etc/init.d/mongodUsage: /etc/init.d/mongod {start|stop|status|restart|reload|force-reload|condrestart}[root@vm ~]# /etc/init.d/mongod statusmongod (pid 1341) is running...[root@vm ~]#

It indicates that the server is already running.

 

4. server configuration:/etc/mongod. conf

The above are some parameters in the default configuration file. For more parameters, run the mongod-H command.
