Discuz Database Storage Path and Configuration Tutorial: Detailed Analysis of MySQL and MariaDB

Discuz Database Storage Path Explained

Discuz is a widely used open-source forum software, and its database is the key component for storing all forum data. Understanding the database storage path is very important when setting up a forum with Discuz. This article will explain the Discuz database storage path in detail and provide some specific code examples to help readers better understand and apply the configuration.

Basic Concept of Database Storage Path

In Discuz, the database storage path refers to the specific location where the database files are stored on the server. Typically, the database storage path is determined by parameters in the database server’s configuration file. Common database servers used with Discuz include MySQL and MariaDB.

MySQL Database Storage Path Configuration

For MySQL databases, the storage path is specified by the datadir parameter in the my.cnf configuration file. The datadir parameter defines the directory for MySQL’s data files. By default, the datadir parameter is usually set to /var/lib/mysql.

If you need to change the MySQL database storage path, follow these steps:

• Open the MySQL configuration file my.cnf, typically located at /etc/mysql/my.cnf.
• Find the datadir parameter and change it to a new storage path, such as: datadir = /newpath/mysql.
• Save and close the configuration file, and then restart the MySQL database service to apply the changes.

Example code:

<span class="fun">sudo nano /etc/mysql/my.cnf</span>

Find and change the datadir parameter to the new path:

<span class="fun">datadir = /newpath/mysql</span>

Restart MySQL service:

<span class="fun">sudo systemctl restart mysql</span>

MariaDB Database Storage Path Configuration

MariaDB is a fork of MySQL, and its database storage path configuration is similar to MySQL. In MariaDB, the database storage path is also specified in the my.cnf configuration file.

Similar to MySQL, the storage path for MariaDB can be configured using the same steps mentioned above.

The example code for MariaDB configuration is similar to MySQL, and will not be repeated here.

Important Notes on Database Storage Path

• Before changing the database storage path, make sure to back up important data to avoid data loss.
• After changing the database storage path, you need to restart the database service for the changes to take effect.
• Pay attention to permissions to ensure the database server has the necessary access rights to read the new storage path.

Conclusion

Through this article, readers can better understand the Discuz database storage path configuration and how to modify the storage path of their database. In practical use, knowing how to configure the database storage path is very important for maintaining and managing forum data. We hope that readers, through learning from this article, can operate the Discuz database more proficiently, ensuring the safety and stability of forum data.
