下面应该是数据存放路径:

我找了半天也没找到my.cnf文件在哪(windows是my.ini,linux是my.cnf)。请问各路高人,是否也遇到过这情况?我怎么才能自定义配置我的数据库啊???谢谢过了!!!

------解决方案--------------------
/etc/my.cnf
------解决方案--------------------
关于linux下my.ini配置文件的加载顺序,

(linux下,/etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

如果这几个位置都找不到呢?
ps -ef | grep mysql
看看mysql进程的详细命令里指向的是哪个配置文件
