Replicate Multiple WordPress Accounts


Replicate multiple WordPress accounts to one or many databases.

CData Sync for WordPress is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple WordPress connections. In this article we show how to use the CLI to replicate multiple WordPress accounts.

Configure WordPress Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple WordPress accounts, use multiple configuration files. Below is an example configuration to replicate WordPress to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>Url=http://www.yourwordpresshost.com;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>Url=http://www.yourwordpresshost.com;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

See the Getting Started guide in the CData driver documentation for more information.

Configure Queries for Each WordPress Instance

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the WordPress API. The statement below caches and incrementally updates a table of WordPress data:

REPLICATE Categories;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple WordPress accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Categories SELECT * FROM Categories

Alternatively, you can use a different schema:

REPLICATE PROD.Categories SELECT * FROM Categories

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

WordPressSync.exe -g MyProductionWordPressConfig.xml -f MyProductionWordPressSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar WordPressSync.jar -g MyProductionWordPressConfig.xml -f MyProductionWordPressSync.sql
