MySQL Server Administration Basics

Study Notes

MySQL server administration is crucial for database operation, security, and performance optimization.
Administrators manage users, backups, and performance tuning to maintain data integrity and availability.

Access controls and authentication prevent unauthorized access and malicious activities.
Data validation and constraints ensure data accuracy and consistency.
Backup and recovery procedures protect against data loss.
Server performance monitoring proactively identifies and addresses potential issues affecting data integrity and availability.

Unauthorized access due to weak user management and access controls allows unauthorized users to access or manipulate sensitive data.
Data breaches and leakage result from improper security configurations like inadequate encryption or a lack of auditing.

Configuring database servers to handle increasing workloads and user activity.
Implementing indexing, caching, and query optimization improves query execution speed.
Monitoring system performance metrics identifies opportunities for capacity planning and scaling.
Using replication and clustering solutions distribute workload and improve fault tolerance.

Configuration of user privileges for specific tables in MySQL Workbench is possible.
Accessing the "Users and Privileges" section, selecting the user, and navigating to "Schema Privileges" allows for fine-grained control of user access to specific data tables.
Specifying privileges for individual tables within the selected database schema provides granular user access control.
SQL injection attacks occur due to insufficient input validation and improper handling of SQL queries and lead to data manipulation or theft.
Denial of Service (DoS) attacks may occur if configurations are poorly optimized or inadequate resource management is practiced. This can disrupt service availability.
