- How to backup and restore database after mysql installation
- There is no absolutely optimal MySQL database backup and recovery solution, and it needs to be selected based on the amount of data, business importance, RTO and RPO. 1. Logical backup (mysqldump) is simple and easy to use, suitable for small databases, but slow and huge files; 2. Physical backup (xtrabackup) is fast, suitable for large databases, but is more complicated to use. The backup strategy needs to consider the backup frequency (RPO decision), backup method (data quantity and time requirement decision) and storage location (off-site storage is more secure), and regularly test the backup and recovery process to avoid backup file corruption, permission problems, insufficient storage space, network interruption and untested issues, and ensure data security.

- How to optimize database performance after mysql installation
- MySQL performance optimization needs to start from three aspects: installation configuration, indexing and query optimization, monitoring and tuning. 1. After installation, you need to adjust the my.cnf file according to the server configuration, such as the innodb_buffer_pool_size parameter, and close query_cache_size; 2. Create a suitable index to avoid excessive indexes, and optimize query statements, such as using the EXPLAIN command to analyze the execution plan; 3. Use MySQL's own monitoring tool (SHOWPROCESSLIST, SHOWSTATUS) to monitor the database health, and regularly back up and organize the database. Only by continuously optimizing these steps can the performance of MySQL database be improved.
