MongoDB has been continuously increasing in recent years as a NoSQL Database. More and more enterprises are trying to replace the original Database with MongoDB. MongoDB also performs well in clusters, sharding, and replication. I will introduce various MongoDB deployment experiments.

Article 1 MongoDB master-slave replication experiment master/slave, divided into five parts

System Environment Introduction:

Ubuntu 12.04. LTS 64bit Server

Simple MongoDB Installation

Add the 10gen source to the source. list file.

~ Vi/etc/apt/source. list
Deb dist 10gen
~ Sudo apt-get update
~ Sudo apt-get install mongodb-10gen

Initialize the file directory (MongoDB storage)

~ Pwd
/Home/conan/dbs

~ Mkdir master slave
~ Ls-l
Drwxrwxr-x 2 conan 4096 May 31 13:54 master/
Drwxrwxr-x 2 conan 4096 May 31 14:04 slave/

Start master

~ Mongod -- dbpath/home/conan/dbs/master -- port 10000 -- master -- rest -- nojournal -- fork -- logpath/home/conan/dbs/master. log
About to fork child process, waiting until server is ready for connections.
Forked process: 4827
All output going to:/home/conan/dbs/master. log
Child process started successfully, parent exiting

Start slave

~ Mongod -- dbpath/home/conan/dbs/slave -- port 10001 -- slave -- source localhost: 10000 -- rest -- nojournal -- fork -- logpath/home/conan/dbs/slave. log
About to fork child process, waiting until server is ready for connections.
Forked process: 5062
All output going to:/home/conan/dbs/slave. log
Child process started successfully, parent exiting

Insert data to the master for testing

~ Mongo localhost: 10000
MongoDB shell version: 2.4.3
Connecting to: localhost: 10000/test
> Db. master. insert ({uid: 1000 })
> Db. master. find ()
{"_ Id": ObjectId ("51a83e979d113ea810e6ddbd"), "uid": 1000}

Query data in slave

~ Mongo localhost: 10001
MongoDB shell version: 2.4.3
Connecting to: localhost: 10001/test
> Db. master. find ()
{"_ Id": ObjectId ("51a83e979d113ea810e6ddbd"), "uid": 1000}

In slave, we found the data, which was synchronized from the master. The experiment is complete!

The master-slave experiment is the simplest deployment experiment for MongoDB.
