[1] | MariaDB सर्वर स्थापित करें। |
[root@www ~]#
dnf module -y install mariadb:10.9/server
[root@www ~]#
vi /etc/my.cnf.d/charset.cnf # नया निर्माण # डिफ़ॉल्ट वर्णसेट सेट करें # यदि सेट नहीं है, तो डिफ़ॉल्ट [latin1] है # 4 बाइट्स UTF-8 के मामले में, निर्दिष्ट करें [utf8mb4] # 3 बाइट्स UTF-8 के मामले में, [utf8mb3] निर्दिष्ट करें (अप्रत्याशित) # [utf8] ⇒ [utf8mb3] का उपनाम [mysqld] character-set-server = utf8mb4 [client] default-character-set = utf8mb4 systemctl enable --now mariadb |
[2] | यदि Firewalld चल रहा है और आप दूरस्थ होस्ट से MariaDB सर्वर तक पहुंचने की अनुमति देना चाहते हैं, तो सेवा की अनुमति दें। MariaDB [3306/TCP] का उपयोग करता है। |
[root@www ~]# firewall-cmd --add-service=mysql success [root@www ~]# firewall-cmd --runtime-to-permanent success |

[root@www ~]# mysql_secure_installation 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.
