Debian 9 and MongoDB

Debian 9 and MongoDB

This week I upgraded my Mint running under Debian 9.3 (LMDE 3).  

See:

lucio@lucio:~$ cat /etc/debian_version 
9.3

So, I installed Mongo using the default repository. My current version of python 3 is 3.5.3, and I do not want to update python because I'm afraid to break my project - maybe I have to upgrade the pip packages if I did.

Ok... I tried updating python and using it with Mongo 4.0, but the numpy didn't work...and maybe many others too. So, I gave up.

Installing Mongo

lucio@lucio:~$ sudo apt install mongodb

So, this are the versions of my installations.

lucio@lucio:~/desenv/project$ python3 -V
Python 3.5.3

lucio@lucio:~$ mongod --version
db version v3.2.11
git version: 009580ad490190ba33d1c6253ebd8d91808923e4
OpenSSL version: OpenSSL 1.0.2q  20 Nov 2018
allocator: tcmalloc
modules: none
build environment:
    distarch: x86_64
    target_arch: x86_64

It worked fine!

Restoring backups

It's easy restoring backups in Mongo, just use mongorestore - mongorestore <backup path>.

lucio@lucio:~$ mongorestore desenv/project/dump/20190207/

Installing Mongo 4.0

I will record here the step by step to install Mongo 4.0 in Debian 9.

Make sure you have the curl installed. If not, install it.

lucio@lucio:~$ sudo apt install curl

Install the key of mongodb repository.

lucio@lucio:~$ curl https://www.mongodb.org/static/pgp/server-4.0.asc | sudo apt-key add -

Create the file mongodb-org-4.0.list:

lucio@lucio:~$ sudo vim /etc/apt/sources.list.d/mongodb-org-4.0.list

This will open a new blank file. Paste in the following:

deb http://repo.mongodb.org/apt/debian stretch/mongodb-org/4.0 main

Save and close the file, then update your package cache:

lucio@lucio:~$ sudo apt update

Install the mongodb-org package to install the server and some supporting tools:

lucio@lucio:~$ sudo apt install mongodb-org

Finally, enable and start the mongod service to get your MongoDB database running:

lucio@lucio:~$ sudo systemctl enable mongod
lucio@lucio:~$ sudo systemctl start mongod

Check if Mongo is running:

lucio@lucio:~$ sudo systemctl status mongod

That's all!!!
