Title: SharDB Author: Ron Rennick Published: 23. Dezember 2009 Last modified: 29. Juni 2014 --- Plugins suchen Dieses Plugin wurde **nicht mit den 3 neuesten Hauptversionen von WordPress getestet**. Es wird möglicherweise nicht mehr gepflegt oder unterstützt und kann bei der Verwendung mit neueren WordPress-Versionen zu Kompatibilitätsproblemen führen. ![](https://s.w.org/plugins/geopattern-icon/shardb.svg) # SharDB Von [Ron Rennick](https://profiles.wordpress.org/wpmuguru/) [Herunterladen](https://downloads.wordpress.org/plugin/shardb.2.8.1.zip) * [Details](https://de.wordpress.org/plugins/shardb/#description) * [Rezensionen](https://de.wordpress.org/plugins/shardb/#reviews) * [Installation](https://de.wordpress.org/plugins/shardb/#installation) * [Entwicklung](https://de.wordpress.org/plugins/shardb/#developers) [Support](https://wordpress.org/support/plugin/shardb/) ## Beschreibung This is intended for larger WordPress Network installs using an existing 1-3 character MD5 hash (by blog id) based multi-DB sharding structure. It supports 16, 256 or 4096 database shards. It also supports a separate database for blog id 1 and multiple VIP databases (home & VIP code contribution by Luke Poland). It should support any plugin that works with (and accesses all data via) the regular WordPress database code. It has been used to power MU version 2.7.1 through WordPress 4.8 sites and upgrade sites from 2.7.1 through to the WordPress 4.8. A detailed [installation guide](http://wpebooks.com/shardb-installation-guide/) can be purchased for a nominal fee. This plugin is based on [HyperDB](https://wordpress.org/extend/plugins/hyperdb) which is the database plugin used by [WordPress.com](http://wordpress.com/). Like HyperDB, this plugin autodetects whether a query is requesting a global or blog table. ## Screenshots * [[ * Site admin blogs screen showing dataset / partition for each blog. ## Installation 1. The database configuration instructions are at the top of db-settings.php. The configuration instructions assume that: 2. a. your databases all have the same database server, user & password. b. your blog shard databases are named according to the same prefix and a suffix of md5 hash, global, home or vipX. 3. Instructions for adding VIP databases are at the bottom of db-settings.php. 4. Once finished editing db-setting.php upload it to the same folder as wp-config. php for your WordPress install. 5. Edit your wp-config.php and add the following line after the database settings are defined: require_once(‚db-settings.php‘); 6. upload shardb-admin.php to /wp-content/plugins/. 7. Network activate the SharDB admin tools in Network Admin -> Plugins. 8. Migrate your data to your DB shards using the SharDB migration screen under Network Admin -> Settings on the main site. 9. upload db.php to /wp-content/. ## FAQ Installation Instructions 1.

April 2019 This plugin was so great, I was using multi-db developed by wpmudev before, but it wasn’t working after php7. So I moved multi-db to shardb.
