Настоятельно рекомендуется архивировать базу данных на регулярной основе и перед обновлением блога.
В этом случае становится возможным восстановить базу данных из резервной копии, если что-то пойдёт не так.
phpMyAdmin — это программа для выполнения операций с базой данных.
If you wanted, you could download a backup in each of the compression formats. Your choice. For example: None and "zipped":
Remember - you have NOT backed up the files and folders - such as images - but all your posts and comments are now safe.phpMyAdmin не справляется с большими базами данных, в этом случае поможет использование MySQL напрямую.
1. Перейдите в директорию, в которую вы хотите сохранить бэкап:
user@linux:~> cd files/blog
2. Используйте команду mysqldump
для выгрузки всех таблиц базы данных. Чтобы выгрузить только некоторые таблицы из базы данных, укажите их имена в конце команды как (имя_таблицы имя_таблицы имя_таблицы)
, только не вводите круглые скобки ( )
. (За более подробным описанием, обратитесь к man mysqldump
.):
user@linux:~/files/blog> mysqldump --add-drop-table -h mysqlhostserver -u mysqlusername -p databasename (tablename tablename tablename) | bzip2 -c > blog.bak.sql.bz2 Enter password: (введите ваш пароль mysql) user@linux~/files/blog>
Пример: mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp | bzip2 -c > blog.bak.sql.bz2 Enter password: my-password user@linux~/files/blog>
Команда bzip2 -c
после | (pipe, конвейер) означает, что бэкап будет сжат на лету, а > blog.bak.sql.bz2
отсылает вывод bzip
в файл под названием blog.bak.sql.bz2
. То же самое можно сделать с помощью двух последовательно выполненных команд:
mysqldump --add-drop-table -h db01.example.net -u dbocodex -p dbwp > blog.bak.sql bzip2 blog.bak.sql
MySQL Administrator is a program for performing administrative operations, such as configuring your MySQL server, monitoring its status and performance, starting and stopping it, managing users and connections, performing backups, restoring backups and a number of other administrative tasks. You can perform most of those tasks using a command line interface such as that provided by mysqladmin or mysql, but MySQL Administrator is advantageous in the following respects:
MySQL Administrator is designed to work with MySQL servers versions 4.0 and above.
MySQL Admin may be downloaded from the MySQL.Com site. Installation binaries and documentation may also be found there.
This assumes you have already installed MySQL Admin and set it up so that you can login to the MySQL Database Server either locally or remotely. Refer to the documentation that comes with the installation package of MySQL Admin for your platform for installation instructions.
1. Open the MySQL Admin client and login as you had previously set up to do.
2. From the icon menu on the left hand side of the client window select Backup.
3. If you have not already created a Backup Project, do this now by clicking on the "New Project" button at the lower part of the window and type in a name for the Backup Project where prompted.
4. Select one or more databases that you want to Backup (in the MySQL Admin client these are called a "Schema" (pl. "Schemata")). Add them to the Backup Content window on the right using the right-pointing arrow button.
5. When you have selected the Schema(ta), you can save the Backup Project. Or you may simply choose to Backup Now using the button on the lower right of the window.
6. A dialogue will come up asking you where to put the Backup. Enter the pathname or browse to the location using the dialogue.
7. Assuming all is correct (and you have write permissions in the directory to which you are writing the Backup), the backup will complete shortly.
1. Open the MySQL Admin client and login as you had previously set up to do.
2. From the icon menu on the left hand side of the client window select Restore.
3. Click the "Open Backup File" button on the lower right of the window.
4. Type in or browse to the Schema(ta) backup file and select. Click "Open".
5. The Target Schema(ta) will most likely be the "Original Location", or you may choose an alternate location using the drop-down menu.
6. Click the "Start Restore" button on the lower right of the window. The database restore will commence.
