i have an issue with Temp table writing on desk with huge number, i have tried many things to avoid this but no luck and i really am giving up but i though i might need some expertise to help solve this issue.
my machine is dedicate to four wordpress site and the server have 8 core and 64GB RAM
every time am running mysqltunner am getting this massage
Temporary tables created on disk: 84% (3K on disk / 3K total)
and the number keep increasing.
from PHPmyadmin i notice this massage :
Issue: Too many sorts are causing temporary tables. Temporary tables average: 1.24 per minute, this value should be less than 1 per hour.
Here is my configuration
[mysqld] log-error=/var/lib/mysql/server.ict-hardware.com.err default-storage-engine=InnoDB performance-schema=ON skip-name-resolve=1 # MyISAM # key-buffer-size = 110M myisam-recover = FORCE,BACKUP join_buffer_size = 4M sort_buffer_size = 4M # SAFETY # max-allowed-packet = 16M max-connect-errors = 1000000 # CACHES AND LIMITS # tmp-table-size = 512M max-heap-table-size = 512M query-cache-type = 0 query-cache-size = 0 max-connections = 500 thread-cache-size = 100 open-files-limit = 65535 table-definition-cache = 8096 table-open-cache = 8096 # INNODB # innodb-flush-method = O_DIRECT innodb-log-files-in-group = 2 innodb-log-file-size = 3075M innodb-flush-log-at-trx-commit = 1 innodb-file-per-table = 1 innodb-buffer-pool-size = 30G innodb_buffer_pool_instances = 30 # LOGGING # log-error = /var/lib/mysql/./mysql-error.log log-queries-not-using-indexes = 1 slow-query-log = 1 slow-query-log-file = /var/lib/mysql/./mysql-slow.log long_query_time = 10 max_allowed_packet=268435456 open_files_limit=2048
