Mongo DB: Failed to connect on Laravel Homestead - laravel

Question

I need to create a new Laravel project and I need to use Mongo DB as a database server. Following the Homestead documentation I added this in my Homeasted.yaml file:
mongodb: true
From what I see in the logs the mongo database is created:
homestead-7: Running: script: Creating Mongo Database: homestead
But after this I received this message:
homestead-7: Running: script: Creating Mongo Database: homestead
homestead-7: MongoDB shell version v3.6.3
homestead-7: connecting to: mongodb://127.0.0.1:27017/homestead
homestead-7: 2019-06-03T10:01:52.103+0000 W NETWORK [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: Connection refused
homestead-7: 2019-06-03T10:01:52.104+0000 E QUERY [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed :
homestead-7: connect#src/mongo/shell/mongo.js:251:13
homestead-7: #(connect):1:6
homestead-7: exception: connect failed
The SSH command responded with a non-zero exit status.
From what I found on the internet it can be that the mongo service is not started. I restarted the box without provisioning this time but with the same result. Command:
vagrant#homestead:~$ mongo
Also, I found some solutions that involve changing of some files on an Ubutu O.S but in my case it will not work because the box will start as a fresh instance.
Any idea how to fix this? Thanks in advance!
Laravel version: 5.8.
Homestead: 8.4.0
MongoDB shell: v3.6.3
LATER EDIT
After the VM has started I executed this command:
sudo apt-get install mongodb
After installation I can execute the "mongo" command:
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.3
Welcome to the MongoDB shell.

Strange, so actually Mongo DB isn't installed?! Even if I added the flag. Now I need to figure how to add it every time when the VM is started.

Answer 1

I managed to fix my problem after hours of searching so I will post the fix.
Because I didn't find anything that could help me I started to check the Homestead scripts in order to understand how Mongo is installed and in homestead.rb I found this line:
# Install MongoDB If Necessary
if settings.has_key?('mongodb') && settings['mongodb']
config.vm.provision 'shell' do |s|
s.name = 'Installing MongoDb'
s.path = script_dir + '/install-mongo.sh'
end
end
So I searched were "install-mongo.sh" is called and I found this condition:
if [ -f /home/vagrant/.mongo ]
then
echo "MongoDB already installed."
exit 0
fi
So Mongo DB is not installed every time only if the "/home/vagrant/.mongo" file doesn't exist. At this point I realized that maybe Mongo failed to be installed but this file was written.
So the solution was to destroy the Vagrant box and recreate it from scratch:
vagrant destroy
vagrant up --provision

Answer 2

In Homestead.yaml under features: add -mongodb: true
and run vagrant reload --provision, that is same as what #NicuVlad has suggested but little bit easier.
