This article mainly introduces "the installation and configuration steps of mongodb". In the daily operation, I believe many people have doubts about the installation and configuration steps of mongodb. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "installation and configuration steps of mongodb". Next, please follow the editor to study!

1. Mongodb installation

1. Download:

Https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.4.10.tgz

2. Installation

[root@node1 mongodb] # tar-xzvf mongodb-linux-x86_64-rhel62-3.4.10.tgz

[root@node1 mongodb] # mv mongodb-linux-x86_64-rhel62-3.4.10 / usr/local/mongodb

[root@node1 mongodb] # vi ~ / .bash_profile

PATH=$PATH:$HOME/bin:/usr/local/mongodb/bin

Export PATH

[root@node1 mongodb] # source ~ / .bash_profile

3. Configuration

(1) creation of data and log directories

[root@node1 mongodb] # mkdir-p / home/mongodb/data

[root@node1 mongodb] # mkdir / home/mongodb/logs

(2) launch configuration file creation

[root@node1 mongodb] # touch / home/mongodb/mongo.conf

Click (here) to collapse or open

Port = 27017

Fork = true

Pidfilepath = / home/mongodb

Dbpath = / home/mongodb/data

Logpath = / home/mongodb/logs/mongodb.log

Logappend = true

OplogSize = 1000

MaxConns = 5000

Profile = 1

Slowms = 5

Shardsvr = true

StorageEngine = wiredTiger

(3) start service configuration

[root@node1 mongodb] # vi / etc/init.d/mongod

[root@node1 mongodb] # chmod uplix / etc/init.d/mongod

[root@node1 mongodb] # chkconfig-- add / etc/init.d/mongod

Click (here) to collapse or open

#! / bin/sh

# chkconfig:-64 36

# description:mongod

Case $1 in

Start)

/ usr/local/mongodb/bin/mongod-f / home/mongodb/mongo.conf

Stop)

/ usr/local/mongodb/bin/mongo 127.0.0.1:27017/admin-- eval "db.shutdownServer ()"

Status)

/ usr/local//mongodb/bin/mongo 127.0.0.1:27017/admin-- eval "db.stats ()"

Esac

4. Start

(1) Command line startup

Do not start http access, listen on port 27017

[root@node1 mongodb] # mongod-dbpath / home/mongodb/data-port 27017-logpath / home/mongodb/logs-logappend

Start http access, http listens on port 28017

[root@node1 mongodb] # mongod-- dbpath / home/mongodb/data-- rest

(2) configuration file startup

[root@node1 mongodb] # mongod-f / home/mongodb/mongo.conf

About to fork child process, waiting until server is ready for connections.

Forked process: 16357

Child process started successfully, parent exiting

(3) Service startup

[root@node1 mongodb] # service mongod start

About to fork child process, waiting until server is ready for connections.

Forked process: 16814

Child process started successfully, parent exiting

5. Close

(1) > use admin

Switched to db admin

> db.shutdownServer ()

Server should be down...

(2) or close directly through the kill command

(3) service mongod stop

6. Connect mongodb

The default port is 27017 and the listening IP address is 127.0.0.1

(1) Direct connection

[root@node1 ~] # mongo

(2) specify connection IP, port, user, and password connection

(3)

II. Daily management of Mongodb

1. Mongodb tool

Bsondump

Mongod

Mongoexport

Mongoimport

Mongoperf

Mongorestore

Mongostat

Mongo

Mongodump

Mongofiles

Mongooplog

Mongoreplay

Mongos

Mongotop

2. Mongodb common commands

(1) View the database

> show dbs # # View all databases

Admin 0.000GB

Local 0.000GB

> db # # View the current database

Test

(2) switch databases

> use admin # # switch to admin database

Switched to db admin

(3)

III. Concept

1. Data comparison

The basic concepts in mongodb are documents, collections and databases.

SQL terminology / concept MongoDB terminology / concept explanation / explanation

Database database database

Table collection database tables / collections

Row document data record rows / documents

Column field data Fields / domains

Index index index

Table joins table join, not supported by MongoDB

Primary key. MongoDB automatically sets the _ id field as the primary key.

-- sysinfo # print some diagnostic system information

-- upgrade # if you need to upgrade the database * Replicaton parameter

-- fastsync # enables the slave library replication service from a dbpath whose database is a snapshot of the master library and can be used to quickly enable synchronization

-- autoresync # if the synchronization data between the slave library and the master database is much worse, it will be resynchronized automatically.

-- oplogSize arg # set the size of oplog (MB) * master / slave parameters

-- master # main library mode
