DBA working skills in MySQL

MySQL is an open source relational database management system that is widely used in Web application development. When developing and operating a MySQL database, the DBA (database administrator) plays a vital role. The DBA must not only provide efficient performance for the database and ensure data security, but also need to have an in-depth understanding of MySQL's internal workflow and techniques. Here are some MySQL DBA work tips.

1. Physical disk partitions and partitions based on RAID technology

In order to obtain better performance and reliability, DBAs need to pay close attention to MySQL server hardware issues. Partitioning of a physical disk can divide the disk capacity into multiple virtual partitions, and each partition will provide better file storage management for the MySQL server. In addition, partitions based on RAID (Redundant Array of Independent Disks) technology can provide a more stable hardware environment for the MySQL server, thereby improving the performance and reliability of the server.

2. Database backup and recovery

DBA needs to spend a lot of time on database backup and recovery, and also needs to ensure the durability and recoverability of the database. MySQL provides a variety of methods to back up and restore databases, including physical backups and logical backups. Physical backup copies the database files directly to the backup target, which is more powerful, but requires more operations and space during recovery; logical backup writes data into the backup file through SQL statements, and the operation is relatively simple.

3. Database Performance Monitoring

DBA needs to constantly monitor the performance of the MySQL database to ensure its stable operation. To do this, you need to use some tools, such as MySQL's own monitor, and third-party tools, such as MySQL Tuner and MySQL Enterprise Monitor. These tools can provide detailed operating indicators, such as server load, response speed and disk I/O, etc., helping DBAs improve database performance.

4. Database Security

Security is the core of any database system. DBAs need to regularly audit the database to ensure its security. In addition, other measures such as encryption, SSL/TLS encryption, IP restrictions and user authorization are also needed to protect data. In addition, DBAs also need to identify risky behaviors and events, such as internal or external hijacking, illegal access and security vulnerabilities, to avoid security issues.

5. Database Maintenance

The DBA needs to pay attention to whether the different components and parts of the MySQL database are functioning properly. Each MySQL module interacts with other components. To do this, aspects such as file systems, access management, and quotas need to be maintained.

In short, MySQL DBA needs to continue to pay attention to the security and performance aspects of the MySQL database, including audits of hardware, network, backup and recovery operations, performance tuning, security and maintenance. If DBA management is carried out properly, the MySQL database will become more reliable, efficient and secure.
