-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Control warning line(s) into /var/log/mysql/error.log file
Control error line(s) into /var/log/mysql/error.log file
Restrict Host for user@% to user@SpecificDNSorIp
Reduce your overall MySQL memory footprint for system stability
Dedicate this server to your database for highest performance.
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: LINK
Read this before increasing for MariaDB LINK
This is MyISAM only table_cache scalability problem, InnoDB not affected.
See more details here: https://bugs.mysql.com/bug.php?id=49177
This bug already fixed in MySQL 5.7.9 and newer MySQL versions.
Beware that open_files_limit (5000) variable
should be greater than table_open_cache (400)
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: LINK
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
join_buffer_size (> 64.0M, or always use indexes with JOINs)
tmp_table_size (> 32M)
max_heap_table_size (> 32M)
table_open_cache (> 400)
innodb_log_file_size should be (=2G) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
