mysql バックアップと復元

Last updated at Posted at 2014-05-06

データベースのバージョン管理ェ…

SQLベースでのバックアップ

# 全てのデータベースをバックアップ
$ mysqldump -u root -x --all-databases > dump.sql
# 特定のデータベースのみバックアップ
$ mysqldump -u root <database_name> > dump.sql
# 複数のデータベースをバックアップする場合はdatabasesオプションを
$ mysqldump -u root --databases DB1 DB2 DB3

mysqldump [OPTIONS] database [tables]とかいう書式でテーブル名も指定できるみたいだ。

SQLベースで復元

普通にmysqlコマンドに渡せばOK

$ mysql -u root -p < dump.sql 
$ mysql -u root database < dump.sql 

メモ

u : user name
p : password
P : port
h : host

d : DDLだけ
