mysql 5.6 數據庫 佔用 內存 過多 的 解決方案

原創 花2不谢 2020-02-24 16:02
下載了mysql5.6.12 ,默認佔用內存達400多M,  而原來使用的5.0 只有30M..


 修改 

 進入   /etc下面   執行vim ./my.cnf



解決方案:調整以下參數 
----------------
performance_schema_max_table_instances=600
table_definition_cache=400
table_open_cache=256






這樣下來,mysql5.6.12就只使用  40---60M左右的內存了.






以下是5.6默認的設置
performance_schema_max_table_instances 12500
table_definition_cache 1400
table_open_cache 2000
