<table> 
 <tbody> 
  <tr> 
   <td style="padding:5px 12px; width:25px; font-size:22px; text-align:center; background:#E8E8E8; line-height:30px; color:#999"> 导读</td> 
   <td style="padding:10px 10px 12px; line-height:20px"><strong>MySQL似乎没有更改数据库名称的语句（也许是我不知道），如果你有数据库服务器的管理权限，可以直接更改一下目录名即可，但如果没有权限，可以通过更改表名达到修改数据库名的目的。下面是把centos数据库更改为centos_old。</strong></td> 
  </tr> 
 </tbody> 
</table>

**1、新建数据库centos\_old.**

mysql > create database centos_old;

**2、使用select concat拼成所有rename table的语句。**

mysql -uroot -p -e "select concat('rename table centos.',table_name,' to centos_old.',table_name,';') from information_schema.TABLES where TABLE_SCHEMA='centos';" > rename_mysql_name.sql

打开rename\_mysql\_name.sql，把第一行删除。

rename\_mysql\_name.sql内容大概为：

rename table centos.wp_commentmeta to centos_old.wp_commentmeta;
        rename table centos.wp_comments to centos_old.wp_comments;
        rename table centos.wp_forum_forums to centos_old.wp_forum_forums;
        rename table centos.wp_forum_groups to centos_old.wp_forum_groups;
        rename table centos.wp_forum_posts to centos_old.wp_forum_posts;
        rename table centos.wp_forum_threads to centos_old.wp_forum_threads;
        rename table centos.wp_forum_usergroup2user to centos_old.wp_forum_usergroup2user;
        rename table centos.wp_forum_usergroups to centos_old.wp_forum_usergroups;
        rename table centos.wp_links to centos_old.wp_links;
        rename table centos.wp_options to centos_old.wp_options;
        rename table centos.wp_postmeta to centos_old.wp_postmeta;
        rename table centos.wp_posts to centos_old.wp_posts;
        rename table centos.wp_term_relationships to centos_old.wp_term_relationships;
        rename table centos.wp_term_taxonomy to centos_old.wp_term_taxonomy;
        rename table centos.wp_terms to centos_old.wp_terms;
        rename table centos.wp_usermeta to centos_old.wp_usermeta;
        rename table centos.wp_users to centos_old.wp_users;

**3、执行rename语句**

mysql -uroot -p < rename_mysql_name.sql

这样就完成了centos数据库名更改为centos\_old的操作。
