installation

A yum installation

installation steps

1. Configure yum

Create the file/etc/yum.repos.d/mongodb-org-4.0.repo for yum to install MongoDB

Document Details

[mongodb-org-4.0]name=MongoDB Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/gpgcheck=1enabled=1gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

2. Install MongoDB

Install the latest version of MongoDB using the command

sudo yum install -y mongodb-org

If you want to specify a version of MongoDB to install, you need to specify the version separately for each part after the package name, as shown in the following example

sudo yum install -y mongodb-org-4.0.9 mongodb-org-server-4.0.9 mongodb-org-shell-4.0.9 mongodb-org-mongos-4.0.9 mongodb-org-tools-4.0.9

2. Use compressed package to install

prerequisite

MongoDB.tar.gz archive must be installed to use dependencies

yum install libcurl openssl

step

1. Download the compressed package in MongoDB.tar.gz format

MongoDB Download Center.

2. Extract the downloaded compressed package file

tar -zxvf mongodb-linux-*-4.0.9.tgz

3. Add environment variables to ensure that executable files are listed in the directory

MongoDB executable files are in the bin/zip directory. You can follow these suggestions

Copy these executables into your environment variables directory, such as/usr/local/bin

Create links for these executable files from directories in your environment variables or modify your environment variables to include this directory

For example, you can add an initialization script (e.g. ~/.bashrc) to your shell

export PATH=/bin:$PATH

Replace with your actual MongoDB installation path

use

Many Uni-like operating systems restrict the use of system resources like sessions. These limitations may affect MongoDB operations. See more UNIX ulimit Settings

directory path

Common default path

Usually MongoDB uses these default directories via mongod user accounts and

/var/lib/mongo (data)/var/log/mongodb (log)

If you install through package

default directory will be created and the owner of this directory will be set to mongod

If you download it via zip

Default directories need to be created manually

Tip: Depending on your user privileges, you may need to use super privileges to perform these actions

mkdir -p /var/lib/mongomkdir -p /var/log/mongodb

By default MongoDB runs using the mongod user account. Once created, set the owner and organization of these directories to mongod

chown -R mongod:mongod

Instead of using the default directory, create the directory you want to use and modify the configuration file/etc/mongod.conf

storage.dbPath to specify a new data directory path (e.g. /some/data/directory)systemLog.path to specify a new log file path (e.g. /some/log/directory/mongod.log)

Confirm that running MongoDB has access to these directories

chown -R mongod:mongod

initiation step

1. Open MongoDB

Start MongoDB with the command

sudo service mongod start

Check if MongoDB has been successfully started

The requested URL/var/log/mongodb/mongod.log was not found on this server.

[initandlisten] waiting for connections on port

port Default configuration 27017, configuration location/etc/mongod.conf

You can confirm that MongoDB will track the reboot system by tracking commands

sudo chkconfig mongod on

Stop MongoDB

sudo service mongod stop

Restart MongoDB

sudo service mongod restart

Start using MongoDB

Open a mongo shell on the same host. You can run the mongo shell without any command-line options to connect to your local instance of mongod with default port 27017.

5. Uninstall MongoDB

Unloading will erase data. Please confirm before unloading.

1) Stop MongoDB

sudo service mongod stop

(2) Remove the package

sudo yum erase $(rpm -qa | grep mongodb-org)

(3) Remove the data directory

sudo rm -r /var/log/mongodbsudo rm -r /var/lib/mongo About how to install MongoDB in Centos is shared here. I hope the above content can be of some help to everyone and learn more. If you think the article is good, you can share it so that more people can see it.
