How to install MongoDB in ubuntu

In this topic, we will learn how to install MongoDB in ubuntu and start the server. We can also install different versions of the MongoDB community as per our requirements.

For installing MongoDB in Ubuntu first, we need to install prerequisite packages. So, install the packages by using this command:

sudo apt-get install libcurl4 openssl liblzma5

Now, download the MongoDB by using this link:

After clicking on this link, you will go to the official website of MongoDB from where you can download

• From version dropdown, select the version of MongoDB that you want to download.
• From platfrom dropdown, select your opearing system version and architecture.
• From package dropdown, choose tgz.
• Now, click on download button.

After Successfully downloading, we need to follow some steps to install in our machine:

• With the help of tar command extract the files.

tar -zxvf mongodb-linux-*-5.0.2.tgz

Note that, If you download different releases of MongoDB then modify the command.

• Now copy all the binaries in your PATH environment variable.

sudo cp <mongodb-install-directory>/bin/* /usr/local/bin/

This step is optional because first, you check manually that all the binaries all listed or not. If not then with the help of this command you can do it easily.

• Now, we need to install MogoDB shell(Mongosh) to connect deployment.
• You can download by using this link

After downloading, you need to follow these steps to run MongoDB:

• Create the data and log directories

• For storing the data, create a directory to store data

sudo mkdir -p /var/lib/mongo

• For string the log, create a directory to store its log

sudo mkdir -p /var/log/mongodb

• Now we need to provide the read write permission to these directories so that user can easily start MongoDB process

sudo chown `whoami` /var/lib/mongo     
sudo chown `whoami` /var/log/mongodb

• MongoDB Run

mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log --fork

Note that, here –dbpath means, the directory where MongoDB stores its data and –logpath means, it will send all the logging information to a log file instead of to the host syslog system.

• MongoDB started successfully and we can also checking the process output by following line in the log file: /var/log/mongodb/mongod.log:

[initandlisten] waiting for connections on port 27017

• We can start using MongoDB by using this command

mongosh

This command will connect to a mongod that is running on localhost with default port 27017.

In this, We learned how we can install MongoDB in Ubuntu and how easily we can run this in our local system.

How to install MongoDB in macOS

In this topic, we will learn how to install MongoDB in macOS and start the server. We can also install different versions of the MongoDB community as per our requirements.

macOS 10.14 or later, we can use for MongoDB 5.0 Community Edition. Now, follow these steps to install MongoDB :

• First of all, download the MongoDB by using this link.

After clicking on this link, you will go to the official website of MongoDB from where you can download

• From version dropdown, select the version of MongoDB that you want to download.

tar -zxvf mongodb-macos-x86_64-5.0.tgz

• Now, check all the binaries in a PATH environment variable, if not then all are binaries are in bin/ directory
• In the PATH variable, copy all the binaries by usig this command

sudo cp /path/to/the/mongodb-directory/bin/* /usr/local/bin/

• The directory listed in your PATH variable, create a symbolic links to the binaries

sudo ln -s  /path/to/the/mongodb-directory/bin/* /usr/local/bin/

Follow these steps to Run MongoDB Community Edition:

• First create the data directory

sudo mkdir -p /usr/local/var/mongodb

You must have to create a directory so that mongod will write the data.

• After the data directory, you must have to create the log directory in mongod process write its log file

sudo mkdir -p /usr/local/var/log/mongodb

• We also need to provide user account mongod toread and write permission for these two directories

sudo chown my_mongodb_user /usr/local/var/mongodb
sudo chown my_mongodb_user /usr/local/var/log/mongodb

Note that, if you are running mongod your own user account and all also create above two directories then you don’t need to provide the ownership because they already having the permission to access the user.

• Run mongod process at the system prompt to run MongoDB by using this command

mongod --dbpath /usr/local/var/mongodb --logpath /usr/local/var/log/mongodb/mongo.log --fork

• On system prompt, run mongod with configuration file with config parameter

mongod --config /usr/local/etc/mongod.conf

• With the help of this command we can verify that MongoDB has successfully started

ps aux | grep -v grep | grep mongod

Note that, if the mongod process is not running, then you can check the log file for any error.

• We can start using MongoDB by using this command

mongosh

After executing this comm This command will connect to a mongod that is running on localhost with default port 27017.

In this, We learned how we can install MongoDB in macOS and how easily we can run this in our local system.
