在网上找了好多,没有确定哪个是最终的答案,由于网站在运行中,实在不敢轻易动手,怎么奈我是个菜鸟呢!先把找到的东西简单记录一下,回头再说!

 

还有一个:

首先在数据库里看一下数据库里当前数据文件的存放路径:

mysql> show variables like '%dir%';
+----------------------------+----------------------------+
| Variable_name | Value |
+----------------------------+----------------------------+
| basedir | / |
| character_sets_dir | /usr/share/mysql/charsets/ |
| datadir | /data/mysql/ |
| innodb_data_home_dir | |
| innodb_log_arch_dir | |
| innodb_log_group_home_dir | ./ |
| innodb_max_dirty_pages_pct | 90 |
| slave_load_tmpdir | /tmp/ |
| tmpdir | /tmp/ |
+----------------------------+----------------------------+

如果你觉得这个路径可以的话,就不用去修改了。如果觉得不满意的话,也可以修改。

1:service mysql stop

关闭数据库

2:vi /etc/rc.d/init.d/mysql

3: 把 datadir=/var/lib/mysql 这里改成你想要的。就OK了

4:service mysql start
