Migrating From One Deki Instance To Another
Table of contents
First, create a fresh install of MindTouch Deki on a server (installation guides can be found at wiki.mindtouch.com).
Backing up your database
You can do this from command line by issuing the following command:
# mysqldump -udbusername -p db_name > db_name.sql
Note: If you have a multi-tenant installation of Deki, you have multiple databases and will need to back up each database separately.
Backing up your attachments
# cd /path/to/dekiwiki/; # tar cvzpf attachments.tar.gz attachments
Move files to new instance
Copy the backed-up files via scp to the new server:
# scp /path/to/db_name.sql root@destination.server:/path/to/deki # scp /path/to/attachments.tar.gz root@destination.server:/path/to/deki # scp /path/to/dekiwiki/LocalSettings.php root@destination.server:/var/www/dekiwiki/ # scp /etc/dekiwiki/mindtouch.deki.startup.xml root@destination.server:/etc/dekiwiki/
Restoring your database
First, you will need to drop the default database:
mysqladmin -udbusername -pdbuserpassword drop db_name;
Recreate the database, and restore the backup by typing the following commands:
# mysql -udbusername -pdbuserpassword mysql> create database wikidb default charset utf8;
Exit mysql, and restore the database by entering the following:
# mysql -udbusername -p db_name < db_name.sql
Note: If you have a multi-tenant installation of Deki, you have multiple databases and will need to restore each database separately.
After restoring it, a little cleanup work is necessary.
# mysql -udbusername -pdbuserpassword wikidb
mysql> UPDATE config SET config_value='fs' where config_key='storage/type';
mysql> INSERT INTO config (config_key, config_value) VALUES ('storage/fs/path', '/var/www/dekiwiki/attachments');
Exit mysql, and change directory to /var/www/dekiwiki/maintenance, and run the following:
# php update-db.php
Rebuild the stored procedures by entering the following command:
# cat /var/www/dekiwiki/maintenance/archives/funcs-util.sql | sed -e 's/{$wgDBadminuser}/wikiuser/' | mysql -udbusername -pdbuserpassword wikidb
Restoring your attachments
# cd /path/to/deki/; # tar xvzpf attachments.tar.gz # chown -R dekiwiki /var/www/dekiwiki/attachments
Finally, restart Deki:
# /etc/init.d/dekiwiki restart
