Sådan downloader og installerer du MongoDB on Windows og Cloud

Installatørerne til MongoDB are available in both the 32-bit and 64-bit format. The 32-bit installers are good for development and test environments. But for production environments you should use the 64-bit installers. Otherwise, you can be limited in the amount of data that can be stored within MongoDB. It is advisable to always use the stable release for production environments.

Hej Verden MongoDB: JavaScript-driver

Chauffører ind MongoDB are used for connectivity between client applications and the database. For example, if you had a Java programmet og krævede det at oprette forbindelse til MongoDB, then you would require to download and integrate the Java driver, så programmet kan arbejde med MongoDB databasen.

Driveren til JavaScript kommer ud af kassen. De MongoDB shell which is used to work with the MongoDB database is actually a JavaScript shell. To access it:

Trin 1) Go to “C:\Program Files\MongoDB\Server\4.0\bin" og dobbeltklik på mongo.exe. Alternativt kan du også klikke på MongoDB desktop item.

Trin 2) Enter the following program into the shell:

var myMessage='Hello World';
printjson(myMessage);

Code Forklaring:

1. Vi erklærer blot en simpel JavaScript variable to store a string called ‘Hello World’.
2. Vi bruger printjson-metoden til at udskrive variablen på skærmen.

Installer Python Chauffør

Trin 1) Sørg Python is installed on the system.

Trin 2) Install the mongo related drivers by issuing the below command:

Trin 6) Keep the privacy settings as default and click “Start Using Compass”.

Trin 7) You will see the home screen with a list of current databases.

MongoDB Konfiguration, import og eksport

Før du starter MongoDB server, det første nøgleaspekt er at konfigurere databiblioteket, hvor alle MongoDB data will be stored. This can be done in the following way:

Ovenstående kommando 'md \data\db' laver en mappe kaldet \data\db på din nuværende placering. MongoDB vil automatisk oprette databaserne på denne placering, fordi dette er standardplaceringen for MongoDB at gemme sine oplysninger. Vi sikrer bare, at mappen er til stede, så det MongoDB kan finde den, når den starter.

Import af data til MongoDB gøres ved at bruge kommandoen "mongoimport". Følgende eksempel viser, hvordan dette kan gøres.

Trin 1) Create a CSV file called data.csv and put the following data in it:

Employeeid,EmployeeName
1,Guru99
2,Mohan
3,Smith

So in the above example, we are assuming we want to import 3 documents into a collection called data. The first row is called the header line, which will become the field names of the collection.

Trin 2) Issue the mongoimport command.

Code Forklaring:

1. We are specifying the db option to say which database the data should be imported to.
2. The type option is to specify that we are importing a csv file.
3. Remember that the first row is called the header line, which will become the field names of the collection; that is why we specify the –headerline option. And then we specify our data.csv file.

Produktion

Outputtet viser tydeligt, at 3 dokumenter blev importeret til MongoDB.

Eksporterer MongoDB is done by using the mongoexport command.

Code Forklaring:

1. Vi angiver db-muligheden for at sige, hvilken database dataene skal eksporteres fra.
2. We are specifying the collection option to say which collection to use.
3. The third option is to specify that we want to export to a csv file.
4. Den fjerde er at angive, hvilke felter i samlingen der skal eksporteres.
5. Indstillingen –out angiver navnet på den csv-fil, som dataene skal eksporteres til.

Produktion

Outputtet viser tydeligt, at 3 poster blev eksporteret fra MongoDB.

Konfiguration MongoDB server med konfigurationsfil

One can configure the mongod server instance to start up with a configuration file. The configuration file contains settings that are equivalent to the mongod command-line options. For example, suppose you wanted MongoDB to store all its logging information to a custom location, then follow the below steps:

Trin 1) Create a file called “mongod.conf” and store the below information in the file.

1. The first line of the file specifies that we want to add configuration for the system log file, that is where the information about what the server is doing goes, in a custom log file.
2. Den anden mulighed er at nævne, at placeringen vil være en fil.
3. This mentions the location of the log file.
4. LogAppend: "true" betyder at sikre, at logoplysningerne bliver ved med at blive tilføjet til logfilen. Hvis du angiver værdien som "false", vil filen blive slettet og oprettet på ny, hver gang serveren starter igen.

Trin 2) Start the mongod server process and specify the above created configuration file as a parameter. The screenshot of how this can be done is shown below.

Once the above command is executed, the server process will start using this configuration file, and if you go to the /etc directory on your system, you will see the mongod.log file created. The below snapshot shows an example of what a log file would look like.
