MongoDB

mongo分片加複製集配置檔案如下：

所有的機器上都有

  1. shard1配置檔案

  1. [root@ip-10-1-2-32 etc]# more shard1.conf 
  2. logpath=/usr/local/mongodb/logs/mongo_shard1.log
    logappend=true # need logrotae scripts
    fork=true
    journal=true
    port=27019
    #vvvvv = true
    #diaglog = 3
    dbpath=/usr/local/mongodb/shard1
    pidfilepath=/usr/local/mongodb/logs/mongo_shard1.pid
    bind_ip=10.1.2.32
    replSet=shard1
    shardsvr=true


shard2配置檔案
  1. [root@ip-10-1-2-32 etc]# more shard2.conf 
    logpath=/usr/local/mongodb/logs/mongo_shard2.log
    logappend=true # need logrotae scripts
    fork=true
    journal=true
    port=27018
    #vvvvv = true
    #diaglog = 3
    dbpath=/usr/local/mongodb/shard2
    pidfilepath=/usr/local/mongodb/logs/mongo_shard2.pid
    bind_ip=10.1.2.32
    replSet=shard2
    shardsvr=true


Config Server配置檔案
  1. [root@ip-10-1-2-32 etc]# more config.conf 
    logpath=/usr/local/mongodb/logs/mongo_config.log
    logappend=true # need logrotae scripts
    fork=true
    journal=true
    port=27000
    dbpath=/usr/local/mongodb/config
    pidfilepath=/usr/local/mongodb/logs/mongo_config.pid
    configsvr=true

  3. (3.2開始的寫法，必須指定config的複製集)
 （3.2之前的寫法）
  1. ##configdb=10.1.2.32:27000,10.1.2.68:27000,10.1.2.175:27000

1.只想做複製集

  1. 三臺機器配置如下

  1. [root@mysql02 yum.repos.d]# more /home/mongodb/etc/config.cnf
  2. logpath=/home/mongodb/logs/mongo_config.log
  3. logappend=true # need logrotae scripts
  4. fork=true
  5. journal=true
  6. port=27000
  7. dbpath=/home/mongodb/config
  8. pidfilepath=/home/mongodb/logs/mongo_config.pid
  9. replSet=replset      ---複製集名稱
 

 選取第一臺主進行配置
  1. 注意：這個id一定要與上面配置檔案的複製集名稱一樣
  2. > config_replset = {_id: 'replset', members: [ {_id: 0, host: '10.168.17.201:27000', priority:1}, {_id: 1, host: '10.168.17.202:27000'}, {_id: 2, host: '10.168.17.203:27000'}] }
  3. {
  4.         "_id" : "replset",
  5.         "members" : [
  6.                 {
  7.                         "_id" : 0,
  8.                         "host" : "10.168.17.201:27000",
  9.                         "priority" : 1
  10.                 },
  11.                 {
  12.                         "_id" : 1,
  13.                         "host" : "10.168.17.202:27000"
  14.                 },
  15.                 {
  16.                         "_id" : 2,
  17.                         "host" : "10.168.17.203:27000"
  18.                 }
  19.         ]
  20. }

2.只想做分片
  1. 一臺機器上做分片配置即可
  2. [root@mysql04 etc]# ll

和分片加複製集的區別不大！


mongodb 執行時新增新的分片複製集
