MongoDB environments mainly include StandAlone, Replication, and Sharding.

StandAlone: StandAlone environment, usually used for development and testing.

Replication: master-slave structure. One Primary and multiple Secondary may have Arbitry.

Sharding: share nothing structure. Each machine stores only a part of data. The mongod server stores data, and the mongos server routes read/write requests. Metadata is stored in the config database.

Because of the data volume and machine volume, the project eventually uses a Primary, a Secondary, and an Arbitry. My own development environment is Ubuntu and the test environment is CentOS. The 64-bit MongoDB is installed.

Install on Ubuntu

Sudo apt-get install mongodb-10gen

Installation on CentOS

Configure the yum source and create the file:/etc/yum. repos. d/mongodb. repo.

[Mongodb] name = MongoDB Repositorybaseurl = http://downloads-distro.mongodb.org/repo/RedHat/ OS /x86_64/gpgcheck=0enabled=1

Installation command:

Yum install mongo-10gen mongo-10gen-server

Configuration

The configuration file/etc/initd. conf on each machine is changed to the following:

# Database file location (default) dbpath =/var/lib/mongo # log location (default) logpath =/var/log/mongo/mongod. log # pid location (default) pidfilepath =/var/run/mongodb/mongod. pid # keyFile location. The generation method is later (ADD) keyFile =/var/lib/mongo/key # port (default) port = 27017 # logs are appended after each start, logappend = true # Start (ADD) in deamon mode fork = true # open operation logs for fault recovery and persistence (default) journal = true # replica set Name (ADD) replSet = test-set

Run on each machine:

Sudo cmdd-f/etc/cmdd. conf

In my environment, Primary ip: 192.168.1.1, Secondary ip: 192.168.1.2, and Arbitary ip: 192.168.1.3. You can set multiple mongodb ports on a single machine. I have tested it.

Run "mongo" on Primary, open the command line, and Set the Replica Set:

Rs. initiate ({:,: [{:}, {:}, {::,: true}]}); {: "OK": 1}

After the history is successful, wait for a while. He will elect Primary and then check the status of the Replica Set:

Test-set: PRIMARY> rs. status () {: "test-set",: ISODate (),: 7,: [{: 1,:,: 1,: 1,:,: 4086 ,: timestamp (1392972480, 1),: ISODate (),: 0}, {: 2,:,: 1,: 2 ,:,: 3997,: Timestamp (1392972480, 1),: ISODate (),: 0, :}, {: 3 ,:,: 1,: 7,:,: 5781,: true}],: 1}

In this way, the entire replica set is successfully configured, which is relatively simple.
