Recover a MySQL database

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:

The output of the command indicates which approach (A or B) is used by the installation, and will allow you to identify the paths, configuration and commands to use in this guide. Refer to the FAQ for more information on these changes.

Check logs

Before trying to recover a MySQL database, you should check the exact error in the log file. To check the latest entries in the MySQL log file, run the command below:

  • For Bitnami installations following Approach A (using Linux system packages):

  • For Bitnami installations following Approach B (self-contained installations):

Restart and repair the database

Assume the following error in the log file:

MySQL

  • The MySQL database is configured to use InnoDB engine by default. You can add the innodb_force_recovery=1 option in the main MySQL configuration file at /opt/bitnami/mysql/etc/my.cnf to try and fix the database:

  • Start the MySQL database with the following command:

  • Open a new console and try to log in to the database:

  • In this case, the error was related to the mysql.user table. Run these commands:

If the table is recovered, you should see “OK” in the mysql.user status table. Do not forget to remove the innodb_force_recovery option from the my.cnf file and restart the MySQL server again.

If you find a different error or cannot fix an issue, we can try to help at http://community.bitnami.com.

NOTE: We are in the process of modifying the configuration for many Bitnami stacks. On account of these changes, the file paths and commands stated in this guide may change depending on whether your Bitnami stack uses MySQL or MariaDB. To identify which database server is used in your stack, run the command below:

The output of the command indicates which database server (MySQL or MariaDB) is used by the installation, and will allow you to identify which guides to follow in our documentation for common database-related operations.

Check logs

Before trying to recover a MariaDB database, you should check the exact error in the log file. To check the latest entries in the MariaDB log file, run the command below:

Start or stop services on Windows

Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and MacOS) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.

Bitnami native installers include a graphical tool to manage services. This tool is named manager-windows.exe on Windows and is located in the installation directory. To use this tool, double-click the file and then use the graphical interface to start, stop or restart services. Server log messages can be checked in the “Server Events” tab.

Management tool

The Windows native installer creates shortcuts to start and stop services created in the Start Menu, under “Programs -> Bitnami APPNAME Stack -> Bitnami Service”. Servers can also be managed from the Windows “Services” control panel. Services are named using the format APPNAMESERVICENAME, where APPNAME is a placeholder for the application name and SERVICENAME is a placeholder for the service name. For example, the native installer for the Bitnami WordPress Stack installs services named wordpressApache and wordpressMariaDB.

These services will be automatically started during boot. To modify this behaviour, refer to the section on disabling services on Windows.
