安装完后发现，内存和虚拟内存占用都很大。 我的vps总共才1G内存，不需要mysql那么大的内存。 1、关闭innodb使用MYISAM存储引擎 参考http://docs.oracle.com/c

1、关闭innodb使用MYISAM存储引擎
参考http://docs.oracle.com/cd/E17952_01/refman-5.6-en/innodb-turning-off.html
2、添加配置
performance_schema_max_table_instances=200
table_definition_cache=200
table_open_cache=128
==================================================================================
mysql 启动命令 /etc/init.d/mysql start
/etc/my.cnf配置如下
