MongoDB複製集之：安裝部署

準備工作

軟體環境

OS：Oracle Linux 6.5

MongoDB:mongodb3.2.3

 

部署架構

類比有三台伺服器

10.1.5.123:28001 主節點

10.1.5.123:28002 從節點

10.1.5.123:28003 選舉節點

 

複製集架構：一主，一從，一選舉節點

 

下載安裝

mongodb-linux-x86_64-rhel62-3.2.3.tgz

  部署步驟 1.建立目錄及使用者

[root@devtest mongodb]# mkdir conf data log

[root@devtest data]# mkdir 28001 28002 28003

--建立mongo使用者

[root@devtest conf]# groupadd mongod

[root@devtest conf]# useradd -g mongod mongod

  2.建立設定檔

--配置三個執行個體的設定檔（修改相應的連接埠號碼即可）

--節點1

$ vi /home/mongod/mongodb3.2.3/conf/28001.conf

port=28001

bind_ip=10.1.5.123

logpath=/home/mongod/mongodb3.2.3/log/28001.log

dbpath=/home/mongod/mongodb3.2.3/data/28001/

logappend=true

pidfilepath=/home/mongod/mongodb3.2.3/data/28001/28001.pid

fork=true

oplogSize=1024

replSet=MyMongo

 

--節點2

$ vi /home/mongod/mongodb3.2.3/conf/28002.conf

port=28002

bind_ip=10.1.5.123

logpath=/home/mongod/mongodb3.2.3/log/28002.log

dbpath=/home/mongod/mongodb3.2.3/data/28002/

logappend=true

pidfilepath=/home/mongod/mongodb3.2.3/data/28002/28002.pid

fork=true

oplogSize=1024

replSet=MyMongo

 

--節點3

$ vi /home/mongod/mongodb3.2.3/conf/28003.conf

port=28003

bind_ip=10.1.5.123

logpath=/home/mongod/mongodb3.2.3/log/28003.log

dbpath=/home/mongod/mongodb3.2.3/data/28003/

logappend=true

pidfilepath=/home/mongod/mongodb3.2.3/data/28003/28003.pid

fork=true

oplogSize=1024

replSet=MyMongo

  3.啟動mongo複製集

$ mongod -f /home/mongod/mongodb3.2.3/conf/28001.conf

$ mongod -f /home/mongod/mongodb3.2.3/conf/28002.conf

$ mongod -f /home/mongod/mongodb3.2.3/conf/28003.conf

  4.初始化複製集

[mongod@devtest ~]$ mongo 10.1.5.123:28001/admin

MongoDB shell version: 3.2.3

connecting to: 10.1.5.123:28001/admin
