To start the MongoDB server: On a Unix system, run the mongod command. On Windows, run the mongod.exe command. Optional: Set the configuration using the --dbpath, --port, --auth, or --replSet options. Use the mongo command to verify that the connection is successful.
How to start MongoDB
To start a MongoDB database server, follow these steps:
On Unix systems:
- Open a terminal window.
- Navigate to the MongoDB installation directory. By default, it is located in
/usr/local/mongodb/bin. - Run the following command:
<code class="bash">mongod</code>
On Windows systems:
- Open a command prompt.
- Navigate to the MongoDB installation directory. By default, it is located in
C:\Program Files\MongoDB\Server\4.4\bin. - Run the following command:
<code class="bash">mongod.exe</code>
Setting options:
You can also start MongoDB by specifying the following options:
- --dbpath : Specifies the path to the data directory.
- --port : Specifies the port to which MongoDB listens (default is 27017).
- --auth : Enable authentication.
- --replSet : Create a replication set.
Verification starts:
To verify that MongoDB has been started successfully, run the following command:
<code class="bash">mongo</code>
If the connection is successful, you will see the following prompt:
<code class="bash">MongoDB shell version: connecting to: mongodb://127.0.0.1:27017 Server has startup warnings: > 2023-04-04T17:07:38.096 08:00 I NETWORK [initandlisten] Detected data files in /Users/username/mongodb-data created by MongoDB 6.0.8, this version of MongoDB may upgrade these files to a newer format that is not compatible with version 6.0.8. > 2023-04-04T17:07:38.096 08:00 I NETWORK [initandlisten] Detected data files in /Users/username/mongodb-data created by MongoDB 6.0.8, this version of MongoDB may upgrade these files to a newer format that is not compatible with version 6.0.8.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
