Optimize MySQL performance on Linux systems.
Optimize MySQL performance on Linux systems.
Not long ago I set up MySQL with phpMyAdmin (MariaDB) and it’s becoming very sluggish. I’m not a big fan of MySQL, but I need to use it. The database size is around 1GB on Ubuntu 20.04, and I haven’t adjusted any settings. It’s taking a long time to load and can’t handle many writes at once.
Adjust table structures with appropriate primary keys and indexes. Ensure InnoDB buffers are sufficient for your MySQL configuration. Verify memory limits and transaction log sizes in the config file. Prefer InnoDB for most read operations; consider MyISAM only for infrequently modified tables. Use utf8mb4 when handling Unicode data. Analyze slow queries with EXPLAIN or the official analysis tool.
It's referred to as my.cnf. This document outlines available commands in my.cnf: https://getmoven.com/index.php/knowledge...-File.html. Be aware that the settings might not suit your needs, so don't simply copy and paste without understanding their purpose. Focus on parameters like connection limits, memory usage for tables, temporary storage size, sorting options, and RAM allocation—make sure maximum RAM usage is practical for your server's capacity.
Collation details explain what you're seeing. The character set uses UTF8MB4, which supports a wide range of characters and handles things like trailing spaces better than older formats. MariaDB offers collations such as nopad for special cases, like preserving spaces. This article covers recommended settings and updates, especially with new Unicode versions.
