Kuidas alla laadida ja installida MongoDB on Windows ja Pilv

Paigaldajad jaoks 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.

Tere maailm MongoDB: JavaSkripti draiver

Autojuhid sisse MongoDB are used for connectivity between client applications and the database. For example, if you had a Java programm ja nõudis sellega ühenduse loomist MongoDB, then you would require to download and integrate the Java draiver, et programm saaks koos töötada MongoDB andmebaas.

Juht jaoks JavaScript tuleb karbist välja. The MongoDB shell which is used to work with the MongoDB database is actually a JavaScript shell. To access it:

Step 1) Go to “C:\Program Files\MongoDB\Server\4.0\bin” ja topeltklõpsake failil mongo.exe. Teise võimalusena võite klõpsata ka MongoDB desktop item.

Step 2) Enter the following program into the shell:

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

Code Selgitus:

1. Me kuulutame lihtsalt välja lihtsa JavaScript variable to store a string called ‘Hello World’.
2. Kasutame muutuja ekraanile printimiseks printjsoni meetodit.

paigaldama Python juht

Step 1) Tagama Python is installed on the system.

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

pip install pymongo

Installige Ruby draiver

Step 1) Ensure Ruby is installed on the system.

Step 2) Ensure gems is updated by issuing the command:

gem update --system

Step 3) Install the mongo related drivers by issuing the below command:

gem install mongo

paigaldama MongoDB Compass - MongoDB Haldustööriist

1. Full power of the Mongo shell
2. Mitu kestat
3. Mitu tulemust

Step 1) Mine link and click download.

Step 2) Enter details in the popup and click submit.

Step 3) Double click on the downloaded file.

Step 4) Installation will auto-start.

Step 5) Compass will launch with a Welcome screen.

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

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

MongoDB Konfigureerimine, import ja eksport

Enne MongoDB server, esimene võtmeaspekt on konfigureerida andmekataloog, kus kõik MongoDB data will be stored. This can be done in the following way:

Ülaltoodud käsk 'md \data\db' loob teie praeguses asukohas kataloogi nimega \data\db. MongoDB loob sellesse asukohta andmebaasid automaatselt, kuna see on vaikekoht MongoDB selle teabe salvestamiseks. Me lihtsalt tagame kataloogi olemasolu MongoDB leiab selle, kui see algab.

Andmete importimine MongoDB tehakse käsu "mongoimport" abil. Järgmine näide näitab, kuidas seda teha.

Step 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.

Step 2) Issue the mongoimport command.

Code Selgitus:

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.

Väljund

Väljund näitab selgelt, et imporditi 3 dokumenti MongoDB.

Eksport MongoDB is done by using the mongoexport command.

Code Selgitus:

1. Täpsustame suvandi db, et öelda, millisest andmebaasist andmed eksportida.
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. Neljas on määrata, millised kogu väljad tuleks eksportida.
5. Valik –out määrab selle csv-faili nime, kuhu andmed eksportida.

Väljund

Väljund näitab selgelt, et 3 kirjet eksporditi MongoDB.

Seadistamine MongoDB server koos konfiguratsioonifailiga

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:

Step 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. Teine võimalus on mainida, et asukohaks on fail.
3. This mentions the location of the log file.
4. LogAppend: "tõene" tähendab tagamist, et logiteavet lisatakse logifaili pidevalt. Kui määrate väärtuseks "false", siis fail kustutatakse ja luuakse värskena, kui server uuesti käivitab.

Step 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.

Kuidas paigaldada MongoDB pilves (AWS, Google, Azure)

You do not need to install the MongoDB server and configure it. You can deploy a MongoDB Atlase server pilves sellistel platvormidel nagu AWS, Google Cloudja Azure, and connect to the instance using a client. Below are the detailed steps:
