mysql 5.6与5.7内存参数优化内存占用为30MB左右后端
导读:后端开发后端开发说明:mysql 5.6、5.7默认启动占用内存400多M,如果是vps等小内存应用,mysql内存占用率明显偏高,将会导致崩溃,mysql会自动停止。编辑/e如何seo优化推广网站网站seo优化诊断工具。
说明:mysql 5.6、5.7默认启动占用内存400多M,如果是vps等小内存应用,mysql内存占用率明显偏高,将会导致崩溃,mysql会自动停止。 编辑/etc/my.cnf文件在[mysqld]下增加或修改如下参数
performance_schema_max_table_instances = 200 table_definition_cache = 100 table_open_cache = 100。这个三个参企业网站建设数,调低值后内存能明显减小,现在mysql使用内存约60MB左右,就大大降低默认使用的内存。
进一步调整参数
innodb_buffer_pool_size=2M这个三个参数可以调小。 再进一步调整: mysql 5.6默认启用performance_schema,占用很多内存,可以禁用。
完整配置文件如下,内存占用到22M
我的mysql配置如下,如果你使用的cent网站seo优化培训os6 64位,并且是yum安装的(一键脚本)可以自己按照如下照抄,我的是centos6 64位系统
先ssh登录服务器或VPS,在vi /etc/my.cnf
