MariaDB 10.9 : स्थापित करें2023/10/18

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

# [unix_socket] प्रमाणीकरण पर स्विच करें या नहीं
# [unix_socket] प्रमाणीकरण पहले से ही डिफ़ॉल्ट रूप से सक्षम है, इसलिए यह [No] के साथ ठीक है
Switch to unix_socket authentication [Y/n] n
 ... skipping.

You already have your root account protected, so you can safely answer 'n'.

# MariaDB root पासवर्ड सेट करें या नहीं
# [unix_socket] प्रमाणीकरण डिफ़ॉल्ट रूप से सक्षम है, लेकिन
# यदि आप root पासवर्ड सेट करते हैं, तो पासवर्ड प्रमाणीकरण के साथ लॉगिन करना भी संभव है।
# यदि root पासवर्ड सेट नहीं है, तो केवल OS रूट उपयोगकर्ता ही MariaDB रूट उपयोगकर्ता के रूप में लॉगिन कर सकता है
Change the root password? [Y/n] n
 ... skipping.

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

# अनाम उपयोगकर्ताओं को हटाएँ
Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

# root लॉगिन को दूरस्थ रूप से अस्वीकार करें
Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

# परीक्षण डेटाबेस हटाएँ
Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

# विशेषाधिकार तालिकाएँ पुनः लोड करें
Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
