This article is to share with you about how to install MongoDB in Linux, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. Install MongoDB

MongoDB's tar package download address: https://www.mongodb.com/download-center#atlas

Extract the installation package tar-zxvf xxxxxxxxxx.tar

Move to the installation directory mv mongodb-linux-x86_64-xxx / usr/local/mongodb

Add the environment variable echo "export PATH=\ $PATH:/usr/local/mongodb/bin [there will be a directory in the past after decompression, so you need to configure] > / etc/profile.d/mongodb.sh (be careful in this! )

Make the environment variable effective source / etc/profile.d/mongodb.sh

Create Mongodb users and groups useradd-r-M-s / sbin/nologin mongod

* create startup database and startup log mkdir-p / data/mongodb/ {db,log} /

Modify permission chown-R mongod:mongod/data/mongodb/

Configure mongoDB profile: vi / etc/mongod.conf

# mongod.conf

# for documentation of all options, see:

# http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.

SystemLog:

Destination: file

LogAppend: true

Path: / data/mongodb/log/mongod.log

# Where and how to store data.

Storage:

DbPath: / data/mongodb/db

Journal:

Enabled: true

# engine:

# wiredTiger:

# how the process runs

ProcessManagement:

Fork: true # fork and run inbackground

PidFilePath: / var/run/mongodb/mongod.pid # location of pidfile

# network interfaces

Net:

Port: 27017

BindIp: 127.0.0.1 # Listen tolocal interface only, comment to listen on all interfaces.

# security:

# operationProfiling:

# # Enterprise-Only Options

# auditLog:

Note:

If the MongoDB port is not between 27017-27019 and 28017-28019, you need to perform the following steps:

# yum-y install policycoreutils-python

# semanage port-a-t mongod_port_t-p tcp 27017

Create a MongoDB self-startup script vi / etc/init.d/mongod

#! / bin/bash

# mongod-Startup script for mongod

# chkconfig: 35 85 15

# description: Mongo is a scalable, document-oriented database.

# processname: mongod

# config: / etc/mongod.conf

# pidfile: / var/run/mongodb/mongod.pid

. / etc/rc.d/init.d/functions

# things from mongod.conf get there by mongod reading it

# NOTE: if you change any OPTIONS here, you get what you pay for:

# this script assumes all options are in the config file.

Set the MongoDB service to boot automatically

Chmod + x / etc/init.d/mongod

Chkconfig mongod on

Start the MongoDB service

Service mongod start

If the startup is not successful:

Mainly check whether the configured environment variables in the startup script .sh file are correct, and at the same time check whether the permissions of db log are the users and groups configured in the script, and can be executed at the same time.

Verify that the startup was successful:
