Not sure if this is the kind of level you are after but this is what I wrote
up for use in my organisation if we need to perform a complete disaster
recovery of our wiki. This has been tested numerous times for both recovery
on the same server, as well as migrating to another server. I haven't tried
between OS though but don't see there would be any issues with that.
Before doing this, Apache2 needs to be configured in the same manner (ie
same directory root etc), correct php version installed and compiled, etc.
A couple of things: wikidb.servername.$DAY is just a gzipped mysql dump of
the database. wikifiles.$DAY.tbz is simply a tar of the entire directory
structure. I have a cron job run daily to backup both.
Mysql –u root –p
Create database wikidb;
Restore Database files
Cd /<backup location>
Mysql –u root –p wikidb < wikidb.servername.$DAY
Ensure database restored
mysql -u root -p wikidb
<list of tables (about 35 should appear).
Create Wiki User account in MYSQL
Mysql –u root -p
create user 'wikiuser'@'localhost' IDENTIFIED BY 'password to be used:
IMPORTANT make sure this is also the same as in the LocalSettings.php
Grant privileges to wikiuser on wikidb database
Mysql –u root –p
GRANT ALL ON wikidb.* TO wikiuser at localhost IDENTIFIED BY 'password to be
Restore wiki config files and images
Tar –xvjf /<backup location>/wikifiles.$DAY.tbz
Complete restore process complete – to make sure, perform test plan again
Potential things that ** may ** be required are:
/<wiki install>/maintenance/php5 rebuildall.php
Double double check the correct database, username, password are used in the
/<wiki install>/LocalSettings.php file
Make sure apache is set up correctly, and the wiki location set
appropriately in the LocalSettings.php file
