安全快速更改MySQL数据库名称
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。想要了解更多关于windows,linux的知识可以去《linux就该这么学》看看。
操作方法
- 01
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。
