从旧版本升级

警告

Never extract the new version over an existing installation of phpMyAdmin, always first remove the old files keeping just the configuration.

This way, you will not leave any old or outdated files in the directory, which can have severe security implications or can cause various breakages.

Simply copy config.inc.php from your previous installation into the newly unpacked one. Configuration files from old versions may require some tweaking as some options have been changed or removed. For compatibility with PHP 5.3 and later, remove a set_magic_quotes_runtime(0); statement that you might find near the end of your configuration file.

请勿 复制 libraries/config.default.php 为 config.inc.php 因为默认配置文件仅对当前版本有效。

The complete upgrade can be performed in a few simple steps:

1. Download the latest phpMyAdmin version from [https://www.phpmyadmin.net/downloads/](https://www.phpmyadmin.net/downloads/)\.
2. Rename existing phpMyAdmin folder (for example to phpmyadmin-old).
3. Unpack freshly downloaded phpMyAdmin to the desired location (for example phpmyadmin).
4. Copy config.inc.php` from old location (phpmyadmin-old) to the new one (phpmyadmin).
5. Test that everything works properly.
6. Remove backup of a previous version (phpmyadmin-old).

If you have upgraded your MySQL server from a version previous to 4.1.2 to version 5.x or newer and if you use the phpMyAdmin configuration storage, you should run the SQL script found in sql/upgrade_tables_mysql_4_1_2+.sql.

If you have upgraded your phpMyAdmin to 4.3.0 or newer from 2.5.0 or newer (<= 4.2.x) and if you use the phpMyAdmin configuration storage, you should run the SQL script found in sql/upgrade_column_info_4_3_0+.sql.

Do not forget to clear the browser cache and to empty the old session by logging out and logging in again.
