Prerequisites

Working noesis of MongoDB.
MongoDB installed on the host workstation.
A general idea of working with command line/trounce commands.
Ubuntu installed every bit the Operating System on the host workstation.

Steps to Install MongoDB on Ubuntu

Yous can Install MongoDB on Ubuntu or your Linux installation using the following steps:

Footstep i: Importing MongoDB Repositories
Step ii: Installing MongoDB Packages
Step 3: Launching MongoDB every bit a Service on Ubuntu
Step 4: Configuring and Connecting MongoDB
Footstep 5: Uninstall MongoDB on Ubuntu

Step 1: Importing MongoDB Repositories

To begin the installation process for MongoDB, you first need to import the Public key leveraged past the Package Management organization associated with your Ubuntu installation.

Ubuntu's Package Management tools help ensure Bundle consistency and authenticity by cross verifying that these are signed using the GPG keys. Yous tin import the MongoDB Public GPG primal using the following line of code:

          > sudo apt-cardinal adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10</span>

One time you've imported the GPGP key, you lot now need to create the Source list for your MongoDB installation. To practice this, you tin employ the following line of code and create the "/etc/apt/sources.list.d/mongodb-org-iii.iv.list" list file as follows:

          > echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.iv multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.iv.listing

With your list file now created, you tin can install the Local Parcel repository. To exercise this, you lot tin use the following line of code:

          > sudo apt-go update

This completes the first step to Install MongoDB on Ubuntu.

Stride ii: Installing MongoDB Packages

You lot now need to install the latest stable version of MongoDB on your system. You tin can use the post-obit command for the same:

          > sudo apt-go install -y mongodb-org

Install a specific release of MongoDB:

In instance you want to install a specific version of MongoDB on your system, you'll need to specify the version for each component package while installing them. You tin refer the following case to implement this:

          > sudo apt-get install -y mongodb-org=3.4 mongodb-org-server=three.four mongodb-org-crush=3.4 mongodb-org-mongos=iii.4 mongodb-org-tools=iii.4

Pace three: Launching MongoDB as a Service on Ubuntu

With MongoDB upwards and running, you now need to create a Unit file, that can help your system understand the process of managing resources. For example, the most commonly leveraged Unit of measurement file helps determine how to get-go, terminate or auto-manage a service.

To do this, you can create a configuration file, "mongodb.service in /etc/systemd/arrangement", that will assistance manage the MongoDB system.

          > sudo vim /etc/systemd/system/mongodb.service

Now, re-create the post-obit data in your configuration file:

#Unit contains the dependencies to be satisfied before the service is started. [Unit of measurement] Description=MongoDB Database After=network.target Documentation=https://docs.mongodb.org/manual # Service tells systemd, how the service should exist started. # Central `User` specifies that the server will run under the mongodb user and # `ExecStart` defines the startup control for MongoDB server. [Service] User=mongodb Group=mongodb ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf # Install tells systemd when the service should be automatically started. # `multi-user.target` means the server will be automatically started during boot. [Install] WantedBy=multi-user.target

In one case you've created your configuration file, you now need to update the organisation service using the following command:

          > systemctl daemon-reload

Now, starting time/enable the updated systemd service for your MongoDB case:

          > sudo systemctl start mongodb

With your MongoDB instance now up, y'all now need to verify if MongoDB started on port 27017. To do this, y'all tin apply the "netstat" command as follows:

          > netstat -plntu

To verify if your MongoDB instance started correctly, y'all can use the status command as follows:

          > sudo systemctl status mongodb

You can now enable the motorcar-start functionality for your system as follows:

          > sudo systemctl enable mongodb

In instance you desire to terminate or restart your MongoDB instance running on your Ubuntu installation, y'all can use the following lines of code:

          > sudo systemctl stop mongodb  > sudo systemctl restart mongodb

This is how you tin can launch your MongoDB service on Ubuntu and consummate another stride to successfully Install MongoDB on Ubuntu.

Footstep 4: Configuring and Connecting MongoDB

One time you've set up MongoDB as a service, you now need to launch your MongoDB installation. To exercise this, open the Mongo Shell and switch to the database admin mode using the following command:

          > mongo > use admin

Now, create a root user for your MongoDB installation and exit the Mongo Trounce as follows:

          > db.createUser({user:"admin", pwd:"password", roles:[{role:"root", db:"admin"}]})

You lot can now connect with your MongoDB, by first restarting MongoDB and then using the following line of code:

          > mongo -u admin -p admin123 --authenticationDatabase admin

You'll now be able to encounter MongoDB set a connection. You tin use the "show dbs" command equally follow to open a list of all available databases:

          > show dbs

This is how you can successfully Install MongoDB on Ubuntu and successfully launch information technology.

Step 5: MongoDB Tuning

Scaling MongoDB is easy and tin can exist done in both ways, horizontally and vertically. It is essential to ensure the optimal performance of the Database. Horizontal scaling is adding server resources such every bit RAM and CPUs while vertical scaling is adding servers to the configuration.

The operation of the MongoDB Database depends on several factors including Memory use, Number of concurrent connections, and WiredTiger Cache amid others. The default storage engine of MongoDB is WiredTiger which preserves 50% memory. This ways 8GB of RAM will take a 0.5*(8-ane) memory preserver for WiredTiger.

For checking the usage stats and determining if changes are required use the following control given below.

          > db.serverStatus().wiredTiger.cache {   'application threads page read from disk to cache count': 6,   'awarding threads page read from disk to cache time (usecs)': 46,   'application threads page write from cache to deejay count': 184,   'awarding threads page write from cache to deejay time (usecs)': 10501,   'bytes allocated for updates': 65768,   'bytes belonging to page images in the enshroud': 30285,   'bytes belonging to the history shop table in the cache': 571,   'bytes currently in the cache': 104652,   'bytes dirty in the cache cumulative': 2813442,   'bytes not belonging to page images in the cache': 74366,   'bytes read into cache': 28042,   'bytes written from enshroud': 1283385,   'cache overflow score': 0,   'checkpoint blocked folio eviction': 0,   'checkpoint of history store file blocked non-history store folio eviction': 0,   'eviction calls to get a page': ii,   'eviction calls to get a page found queue empty': two,   'eviction calls to get a page institute queue empty after locking': 0,   'eviction currently operating in aggressive mode': 0,   'eviction empty score': 0,   'eviction passes of a file': 0,   'eviction server candidate queue empty when topping upwardly': 0,   'eviction server candidate queue not empty when topping up': 0,   'eviction server evicting pages': 0,   'eviction server slept, because nosotros did not brand progress with eviction': 0,   'eviction server unable to reach eviction goal': 0,   'eviction server waiting for a leaf folio': 0,   'eviction land': 64,   'eviction walk target pages histogram - 0-9': 0,   'eviction walk target pages histogram - x-31': 0,   'eviction walk target pages histogram - 128 and higher': 0,   'eviction walk target pages histogram - 32-63': 0,   'eviction walk target pages histogram - 64-128': 0,   'eviction walk target pages reduced due to history shop enshroud pressure level': 0,   'eviction walk target strategy both clean and dirty pages': 0,   'eviction walk target strategy only clean pages': 0,   'eviction walk target strategy only dirty pages': 0,   'eviction walks abased': 0, ..............

From the above effect, some of the central points to note are listed beneath.

wiredTiger.cache.maximum bytes configure
wiredTiger.cache.bytes currently in the cache
wiredTiger.cache.pages read into cache
wiredTiger.cache.pages written from cache
wiredTiger.cache.tracked dirty bytes in the cache

To bank check the usage of WiredTiger Concurrency Read and Write Ticket, follow the command given below.

          > db.serverStatus().wiredTiger.concurrentTransactions {   write: { out: 0, available: 128, totalTickets: 128 },   read: { out: one, available: 127, totalTickets: 128 } }

Step 6: Uninstall MongoDB on Ubuntu (Optional)

Warning: All databases and their respective configurations would be removed after this process is put in place. Ensure that you lot back up all your data and configuration information before proceeding with this process, as it'southward irreversible.

To uninstall MongoDB on Ubuntu, you start demand to remove the MongoDB packages. To practice this, yous tin can finish the MongoDB service and execute the following command to remove the installed packages:

          > sudo apt-get purge mongodb-org*

Y'all can remove your created databases, log files and directories using the post-obit command:

          > sudo rm -r /var/log/mongodb > sudo rm -r /var/lib/mongodb

This is how you tin uninstall MongoDB on Ubuntu.
