How to Customize phpMyAdmin Auto Logout Time
phpMyAdmin, a popular MySQL management tool, has a default automatic log out time of 1440 seconds (24 minutes). This may be too short for users who need to stay logged in for extended periods. Here's how to adjust or disable this setting:
Adjust Log Out Time:
To change the log out time specifically for phpMyAdmin, edit the config.inc.php file located in the phpMyAdmin installation directory. Add the following lines:
$sessionDuration = 60*60*24*7; // 60*60*24*7 = one week ini_set('session.gc_maxlifetime', $sessionDuration); $cfg['LoginCookieValidity'] = $sessionDuration;
This code sets the session duration to one week (60 minutes 60 seconds 24 hours * 7 days). You can adjust this value to suit your requirements.
Disable Log In Request:
If you want to remove the automatic log out feature entirely, comment out the following line in the config.inc.php file:
$cfg['LoginCookieValidity'] = $sessionDuration;
This will allow users to stay logged in indefinitely until they manually log out.
Additional Note:
Remember to restart phpMyAdmin after making these changes to apply them. If you encounter any issues, consult the phpMyAdmin documentation for further assistance.

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.
