backup Mediawiki

Problem

How to move mediawiki from ubuntu to wsl?

Solution

Notation

[wikifolder]: where your wiki locate
[wikidb]: database wiki uses
[wikidb_user]: user of database
Assuming we have two servers:
Server 1
[wikifolder]: /var/www/html
[wikidb]: wikidb
[wikidb_user]: root
Server 2
[wikifolder]: /var/www/html
[wikidb]: wikidb
[wikidb_user]: wikiuser

Old mediawiki is in Server 1. We'd like to back up it, then scp to Server 2, finally restore from it in Server 2.

backup database in Service 1

First insert the following line into LocalSettings.php

$wgReadOnly = 'Dumping Database, Access will be restored shortly';

this can be removed as soon as the dump is completed.

mysqldump --default-character-set=binary -u root -p -h localhost --opt wikidb > wikidb-backup.sql

For more, See Mysqldump_from_the_command_line, and Back up in schedule

backup website in Service 1

tar czpvf mediawiki-1.23.13-backup.tar.gz /var/www/html

Restore in Service 2

Import the database backup

On the server on which you are restoring MediaWiki, ensure you have

a correctly-working instance of MySQL
a MySQL user with appropriate permissions, if you can't use MySQL user root

mkdir mediawiki_backup && cd mediawiki_backup/
cp /mnt/c/Users/chencanyi/Videos/wikidb-backup.sql ~/mediawiki_backup/ # or you can use scp

If a database exists and you want to entirely replace it from the backup. To destroy the database:

mysqladmin -u wikiuser -p drop wikidb

Then to create a new database and restore from backup:

mysqladmin -u wikiuser -p create wikidb
mysql -u wikiuser -p wikidb < wikidb-backup.sql
php /var/www/html/maintenance/update.php

Import the MediaWiki files

Assuming you are in Service 1.

scp ubuntu@Service1:~/mediawiki_backup/mediawiki-1.23.13-backup.tar.gz ~/mediawiki_backup/
cd ~/mediawiki_backup/
tar -xvzf mediawiki-1.23.13-backup.tar.gz
rm -fR [wikifolder]/
mv ./var/www/html [wikifolder]

Restart apache2 & mysql

sudo service apache2 restart
sudo service mysql restart

Check the configuration file

Something more

where to find database configure?

cd /var/www/html
vi LocalSettings.php
# Something like 
## Database settings
$wgDBtype = "mysql";
$wgDBserver = "localhost";
$wgDBname = "wikidb";
$wgDBuser = "root";
$wgDBpassword = "***";
