安全快速更改MySQL資料庫名稱
導讀MySQL似乎沒有更改資料庫名稱的語句(也許是我不知道),如果你有資料庫伺服器的系統管理權限,可以直接更改一下目錄名即可,但如果沒有許可權,可以通過更改表名達到修改資料庫名的目的。下面是把centos資料庫更改為centos_old。1、建立資料庫centos_old.
mysql > create database centos_old;
2、使用select concat拼成所有rename table的語句。 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開啟rename_mysql_name.sql,把第一行刪除。
rename_mysql_name.sql內容大概為:
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、執行rename語句mysql -uroot -p < rename_mysql_name.sql
這樣就完成了centos資料庫名更改為centos_old的操作。
