Installering af MongoDB Community Edition på Ubuntu 18.04

Før installation

Denne guide viser installationen af MongoDB på Ubuntu version 18.04 og er ikke kompatibel med andre Ubuntu versioner.

Før installationen af MongoDB er det en god ide at have NodeJS installeret. NodeJS arbejder godt sammen med MongoDB hvis man skal vise en Webside med indhold fra MongoDB.

Tip for at indsætte tekst i Ubuntu terminalen tryk på Ctrl + Shift + v.

Installation af MongoDB

  1. Importer den offentlige nøgle brugt af MongoDB

Den offentlige nøgle bliver brugt til at verificere at den pakke der bliver modtaget er en umodificeret version af MongoDB. Kommandoen til den offentlige nøgle er.

wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add –

Så burde der komme en respons som siger ok.

Hvis der i stedet kommer en fejlbesked er det fordi gnupg ikke er installeret.

Gnupg er et værktøj der håndterer kryptering af data over internettet og offentlige nøgler. Gnupg er brugt til at holde forbindelsen sikker imens pakkerne bliver hentet fra internettet. Hvis gnupg ikke er installeret kan Ubuntu ikke verificere pakkerne og vil derfor ikke hente dem.

For at installere gnupg skriv

sudo apt-get install gnupg

derefter prøv at importer nøglen igen.

  1. Lav en list fil til MongoDB

For at lave en list fil til Ubuntu skriv denne kommando.

echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list

  1. Forny den lokale pakke database

For at fornye den lokale pakke database i Ubuntu skriv kommandoen.

sudo apt-get update

  1. Installere den seneste version af MongoDB

For at installere den seneste stabile version af MongoDB skriv Kommandoen.

sudo apt-get install -y mongodb-org


Basale MongoDB kommandoer

  • Start MongoDB

For at starte mongod skriv kommandoen.

sudo service mongod start

  • Verificere at MongoDB har startet

For at verificere at mongod er startet skriv kommandoen.

sudo service mongod status

  • Stop MongoDB

Stop MongoDB ved at skrive kommandoen.

sudo service mongod stop

  • Genstart MongoDB

Genstart MongoDB ved at skrive kommandoen.

sudo service mongod restart

  • Skriv i MongoDB

For at skrive i MongoDB brug kommandoen. mongo

For at komme tilbage til terminalen tryk på Ctrl + c efter det kommer der en besked der siger ”bye” og så er du tilbage i terminalen. Denne kommando stopper ikke MongoDB, den går kun ud af MongoDB terminalen.

MQTT Protocol

MQTT is a handy protocol for sending/receiving lightweight data.

What is MQTT

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

V5.0 and v3.1.1 are OASIS standards (v3.1.1 is also a standard for ISO)

Protocol

The standard ports for MQTT to use.

TCP/IP port 1883 is reserved with IANA for use with MQTT.
TCP/IP port 8883 is also registered, for using MQTT over SSL.

What security does MQTT support.

You can pass a user name and password with an MQTT packet in V3.1 of the protocol. Encryption across the network can be handled with SSL, independently of the MQTT protocol itself (it is worth noting that SSL is not the lightest of protocols, and does add significant network overhead). Additional security can be added by an application encrypting data that it sends and receives, but this is not something built-in to the protocol, in order to keep it simple and lightweight.

Installere XAMPP på Linux

De kender måske XAMPP installations pakke til Windows fra Bitnami. Det er forbavsende nemt at installere en lignende pakke på Ubuntu Linux.

Skriv følgende kommandoer for at download og installere:

wget https://www.apachefriends.org/xampp-files/5.6.20/xampp-linux-x64-5.6.20-0-installer.run
sudo su
chmod +x xampp-linux-x64-5.6.20-0-installer.run
./xampp-linux-x64-5.6.20-0-installer.run

Er du allerede hjemmevant i XAMPP kan du sandsynligvis springe resten over. Er du alligevel nysgerrig, lad os kigge på de forskellige knapper og deres funktioner.
