This guide provides a step-by-step tutorial on how to install MongoDB community edition on CentOS 8. MongoDB<\/a> is a cross-platform document-oriented and a NoSQL database program.<\/p>\n\n\n\n

Installing MongoDB Community Edition on CentOS 8<\/h3>\n\n\n\n

Run system update.<\/h4>\n\n\n\n
dnf update<\/code><\/pre>\n\n\n\n
Create MongoDB RPM Repository<\/h4>\n\n\n\n
As of this writing, the official MongoDB rpm repos for centOS 8 are not yet released and thus the repos providing test MongoDB packages are  available.<\/p>\n\n\n\n
To create the MongoDB rpm repository file, run the command below and enter content below;<\/p>\n\n\n\n
The repository created below is for installing MongoDB 4.2 on CentOS 8.<\/p>\n\n\n\n
<\/code><\/pre>\n\n\n\n
\ncat > \/etc\/yum.repos.d\/mongodb.repo << 'EOL'\n[mongodb-org-4.2]\nname=MongoDB Repository\nbaseurl=https:\/\/repo.mongodb.org\/yum\/redhat\/8\/mongodb-org\/testing\/x86_64\/\ngpgcheck=1\nenabled=1\ngpgkey=https:\/\/www.mongodb.org\/static\/pgp\/server-4.2.asc\nEOL\n<\/code><\/pre>\n\n\n\n
You can as well use the official repos for previous CentOS releases. For example, to use the RPM repos for CentOS 7;<\/p>\n\n\n\n
\ncat > \/etc\/yum.repos.d\/mongodb.repo << 'EOL'\n[mongodb-org-4.2]\nname=MongoDB Repositorybaseurl=https:\/\/repo.mongodb.org\/yum\/redhat\/7\/mongodb-org\/4.2\/x86_64\/\ngpgcheck=1\nenabled=1\ngpgkey=https:\/\/www.mongodb.org\/static\/pgp\/server-4.2.asc\nEOL\n<\/code><\/pre>\n\n\n\n
Once the MongoDB repository, you can install the MongoDB and associated packages by running the command;<\/p>\n\n\n\n
dnf install mongodb-org<\/code><\/pre>\n\n\n\n

Once the installation is done, you can verify the installed version by running the command below;<\/p>\n\n\n\n
mongod --version<\/code><\/pre>\n\n\n\n
\ndb version v4.2.1-rc0\ngit version: edf6d45851c0b9ee15548f0f847df141764a317e\nOpenSSL version: OpenSSL 1.1.1 FIPS  11 Sep 2018\nallocator: tcmalloc\nmodules: none\nbuild environment:\n    distmod: rhel80\n    distarch: x86_64\n    target_arch: x86_64\n<\/code><\/pre>\n\n\n\n
Running MongoDB on CentOS 8<\/h3>\n\n\n\n
MongoDB runs as a non-privileged mongod<\/code> user and it uses the \/var\/lib\/mongo<\/code> (the data directory) and \/var\/log\/mongodb<\/code> (the log directory) default directories.<\/p>\n\n\n\n
MongoDB daemon is managed by systemd. Hence, you can start it by executing the command below;<\/p>\n\n\n\n
systemctl start mongod<\/code><\/pre>\n\n\n\n
To check if MongoDB has run successfully, check its log file, \/var\/log\/mongodb\/mongod.log<\/code><\/strong>. You should be able to see a line indicating the MongoDB is ready and waiting for the connections.<\/p>\n\n\n\n
tail \/var\/log\/mongodb\/mongod.log<\/code><\/pre>\n\n\n\n

Enable MongoDB to run on system boot.<\/p>\n\n\n\n
systemctl enable mongod<\/code><\/pre>\n\n\n\n
Using MongoDB on CentOS 8<\/h3>\n\n\n\n
Once the installation completes, you can now start using MongoDB. MongoDB listens on local address on port 27017 by default. Hence, from the localhost, you can simply login to MongoDB shell by running;<\/p>\n\n\n\n
mongo<\/code><\/pre>\n\n\n\n
...\nMongoDB shell version v4.2.1-rc0\nconnecting to: mongodb:\/\/127.0.0.1:27017\/?compressors=disabled&gssapiServiceName=mongodb\nImplicit session: session { \"id\" : UUID(\"1f77f765-eb9f-414c-9a33-d40d4ad3c2dd\") }\nMongoDB server version: 4.2.1-rc0\nWelcome to the MongoDB shell.\nFor interactive help, type \"help\".\n...\n><\/code><\/pre>\n\n\n\n
From the MongoDB shell, you can run your database management commands. For example to list available databases;<\/p>\n\n\n\n
> db\ntest<\/code><\/pre>\n\n\n\n
To use a specific MongoDB database, simply run;<\/p>\n\n\n\n
use database-name<\/code><\/pre>\n\n\n\n
To create MongoDB database, simply switch to a new database (non-existing databases) by specifying the name of the database to create and insert data into it.<\/p>\n\n\n\n
> use testdatabase\nswitched to db testdatabase<\/code><\/pre>\n\n\n\n
You can now insert data into your new database.<\/p>\n\n\n\n
db.userdetails.insertOne(\n   { \"F_Name\" : \"fname\",\n     \"L_NAME\" : \"lname\",\n     \"ID_NO\" : \"12345\",\n     \"AGE\" : \"19\",\n     \"TEL\" : \"654321\"\n   }\n)<\/code><\/pre>\n\n\n\n
Press Enter to insert the data.<\/p>\n\n\n\n
{\n\t\"acknowledged\" : true,\n\t\"insertedId\" : ObjectId(\"5da6036c387fad741503e4a1\")\n}<\/code><\/pre>\n\n\n\n
To list database collections;<\/p>\n\n\n\n
show collections<\/code><\/pre>\n\n\n\n
To show the data contained in a MongoDB database collection;<\/p>\n\n\n\n
db.NAME-OF-COLLECTION<\/strong>.find().pretty()<\/code><\/pre>\n\n\n\n
Take for example, to list the content of the collection created above;<\/p>\n\n\n\n
> use testdatabase\nswitched to db testdatabase<\/code><\/pre>\n\n\n\n
> show collections\nuserdetails<\/code><\/pre>\n\n\n\n
> db.userdetails.find().pretty()\n{\n\t\"_id\" : ObjectId(\"5da6036c387fad741503e4a1\"),\n\t\"F_Name\" : \"fname\",\n\t\"L_NAME\" : \"lname\",\n\t\"ID_NO\" : \"12345\",\n\t\"AGE\" : \"19\",\n\t\"TEL\" : \"654321\"\n}\n><\/code><\/pre>\n\n\n\n
To create MongoDB database user with read\/write privileges.<\/p>\n\n\n\n
use testdatabase<\/code><\/pre>\n\n\n\n
db.createUser(\n   {\n     user: 'testuser',\n     pwd: 'P@ssWord',\n     roles: [ { role: 'readWrite<\/strong>', db: 'testdatabase' } ]\n   }\n );<\/code><\/pre>\n\n\n\n
Press Enter to add the user.<\/p>\n\n\n\n
Successfully added user: {\n     \"user\" : \"testuser\",\n     \"roles\" : [\n         {\n             \"role\" : \"readWrite\",\n             \"db\" : \"testdatabase\"\n         }\n     ]\n }<\/code><\/pre>\n\n\n\n
To list database users;<\/p>\n\n\n\n
db.getUsers()<\/code><\/pre>\n\n\n\n
\n[\n\t{\n\t\t\"_id\" : \"testdb.testuser\",\n\t\t\"userId\" : UUID(\"e0e3911b-c2b3-4580-b043-1c044b0f51f5\"),\n\t\t\"user\" : \"testuser\",\n\t\t\"db\" : \"testdb\",\n\t\t\"roles\" : [\n\t\t\t{\n\t\t\t\t\"role\" : \"readWrite\",\n\t\t\t\t\"db\" : \"testdatabase\"\n\t\t\t}\n\t\t],\n\t\t\"mechanisms\" : [\n\t\t\t\"SCRAM-SHA-1\",\n\t\t\t\"SCRAM-SHA-256\"\n\t\t]\n\t}\n]\n<\/code><\/pre>\n\n\n\n
If you want to create an administrator for a single database;<\/p>\n\n\n\n
use testdatabase<\/code><\/pre>\n\n\n\n
db.createUser(\n  {\n    user: 'testadmin',\n    pwd: 'P@ssW0rd',\n    roles: [ { role: 'userAdmin<\/strong>', db: 'testdatabase' } ]\n  }\n);<\/code><\/pre>\n\n\n\n
To create an overall database admin with all administrative rights on all databases, use the administrative database and create admin user as follows;<\/p>\n\n\n\n
use admin<\/code><\/pre>\n\n\n\n
db.createUser(\n  {\n    user: 'admin',\n    pwd: 'P@ssW0rd',\n    roles: [ { role: 'userAdminAnyDatabase<\/strong>', db: 'admin' } ]\n  }\n);<\/code><\/pre>\n\n\n\n
