  • 快速搭建MongoDB分布式集群

    目录

    1. Prerequisites

    Suppose:
    (1) you have deploy a functioning network to install mongodb cluster.
    (2) you have gained the latest releases of MongoDB from 10gen.
    (3) you have installed mongodb in the path $MongoHome.
    (4) there are three folders, that are bin,dbs,logs, in $MongoHome folder.
    (5) there are four servers here to make four shards in the cluster.
    (6) their IP4 addresses are:
        +pc3:192.168.0.104
        +pc2:192.168.0.103
        +pc1:192.168.0.102
        host:192.168.0.100

    2. Steps to follow

    #1 biuld up mongod instance on every node.
        using the following CMD in Terminal on every shard marchine:
        -bash bash-install-shard...files.

    bash-install-shard

    #2 set up mongod instance of config server
        using the following CMD in Terminal on every config server marchine:
        -bash bash-install-config

    bash-install-config

    #3 initiate every replica set
        ssh every shard server, run mongo to login its local mongod instance,
        then write a config file for the relica set, and run rs.initate(config).
        see "shard initialize"file for more information.

    shard-initialize

    #4 start mongos server
        using the following CMD in Terminal on every mongos server marchine:
        -bash bash-install-mongos

    bash-install-mongos

    #5 add shards to the cluster
        login one of the mongos, use sh.addShard("shard1/192.168.0.100:27020") CMD to add every shard.
        see "Add shards to the cluster" file for more information.

    Up to now a distributed MongoDB cluster with replica set has established, and its architecture may go like this:
