I recently migrated my development system to a new server. Instead of exporting and importing some very large SQL dumps, I thought I'd save some time by just moving my development database files from my old virtual machine to my new one. I had a bugger of a time getting the database to work properly, as trying to read the tables gave me the error “Table doesn't exist in engine.” Here was the solution (using MariaDB on Debian 10, interfacing via phpMyAdmin).
On the new system, stop the mySQL service, for example:
> /etc/init.d/mysql stop
Back up the new system's database files so that if you screw up you can always start over, for example:
> mv /var/lib/mysql /var/lib/mysql.backup
Copy your old database files to the new system at /var/lib/mysql/
.
Change ownership of the database files to mysql
:
> chown -R mysql:mysql /var/lib/mysql/
MySQL likes permissions to look like -rw-rw-???
. Most likely you will only need to add group-write permission:
> chmod -R g+w /var/lib/mysql/
Restart the mysql service, e.g.
> /etc/init.d/mysql start
Log into mysql from the command line as root
.
Create a database called phpmyadmin
if it doesn't already exist.
Create a user called pma
and set the “host” to the hostname or IP address of your web server (or localhost
if applicable), make a note of the password, and grant the new user full control over the phpmyadmin
database. It is recommended that this user does not have access to anything other than this database. Example query:
GRANT ALL PRIVILEGES ON phpmyadmin.* TO 'pma'@'localhost';
Go to the phpMyAdmin installation directory and find sql/create_tables.sql
, most likely located at /usr/share/phpmyadmin/sql/create_tables.sql
. (On some installations, you may have to extract create_tables.sql
from /usr/share/phpmyadmin/sql/create_tables.sql.gz
.) Open create_tables.sql
in a text editor and copy all text (it's a bunch of SQL queries).
In phpMyAdmin, select the phpmyadmin
database and click on the “SQL” tab. Paste the entire text from create_tables.sql
into the text box, and run the query.
Open the config.inc.php
file in the phpMyAdmin install directory (e.g. /usr/share/phpmyadmin/config.inc.php
), and make sure the following lines are present and configured accordingly:
/* User used to manipulate with storage */ $cfg['Servers'][$i]['controlhost'] = 'localhost'; //$cfg['Servers'][$i]['controlport'] = ''; // Uncomment and fill in if needed $cfg['Servers'][$i]['controluser'] = 'pma'; $cfg['Servers'][$i]['controlpass'] = '[Your database password for user `pma`]'; /* Storage database and tables */ $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin'; // Uncomment the following lines $cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark'; $cfg['Servers'][$i]['relation'] = 'pma__relation'; $cfg['Servers'][$i]['table_info'] = 'pma__table_info'; $cfg['Servers'][$i]['table_coords'] = 'pma__table_coords'; $cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages'; $cfg['Servers'][$i]['column_info'] = 'pma__column_info'; $cfg['Servers'][$i]['history'] = 'pma__history'; $cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs'; $cfg['Servers'][$i]['tracking'] = 'pma__tracking'; $cfg['Servers'][$i]['userconfig'] = 'pma__userconfig'; $cfg['Servers'][$i]['recent'] = 'pma__recent'; $cfg['Servers'][$i]['favorite'] = 'pma__favorite'; $cfg['Servers'][$i]['users'] = 'pma__users'; $cfg['Servers'][$i]['usergroups'] = 'pma__usergroups'; $cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding'; $cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches'; $cfg['Servers'][$i]['central_columns'] = 'pma__central_columns'; $cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings'; $cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';
Save the file.
Restart the mysql service, e.g.
> /etc/init.d/mysql restart
Log out and back into phpmyadmin to ensure changes take effect. (For good measure, it's not a bad idea to clear the server's cookies.)
You should now be able to read tables in your migrated databases without any issues.
