Download Installation

Download Address: Https://www.mongodb.org/downloads

Mongodb-linux-x86_64-rhel62-3.2.3.tgz

Deployment Steps 1. Create Directories and Users

[Root@devtest mongodb]# mkdir conf data log

[Root@devtest data]# mkdir 28001 28002 28003

--Create MONGO user

[Root@devtest conf]# Groupadd Mongod

[Root@devtest conf]# useradd-g Mongod Mongod

2. Create a configuration file

--Configure three instance configuration files (modify the corresponding port number)

--Node 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

--Node 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

--Node 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. Start MONGO replication set

$ 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. Initializing the replica set

[Mongod@devtest ~]$ MONGO 10.1.5.123:28001/admin
