MediaWiki Successfully Updated

update completed: 10:02 PM Tuesday, January 28, 2014

Prior to updating the mediawiki, a few things need to be determined.

First, read MediaWiki Upgrade April 2011 for notes on the last mediawiki upgrade.

Refer to Manual:Upgrading

Determine the current version of MediaWiki. You can find the MediaWiki version on your server in the file includes/DefaultSettings.php. It should be a variable assigned somewhere in the first 50 lines or so. (see Upgrade - need to find version)

Determine the MySQL version. Since the last upgrade the MySQL server was independently updated, as was PHP, Apache, and the OS (kernel_

HowTo Backup and Upgrade XXXXXXXXXXXX in MediaWiki

The unedited version of this guide is called versions.txt and stored on roachnet secure.

steps

1. check requirements, all LAMP versions

2. lock mediawiki from writes

  vi /xxxxx/LocalSettings.php

  add the line:
  $wgReadOnly = 'Dumping Database, Access will be restored shortly';
  (the funny thing is that this line did nothing on version 1.16.4)

3. backup wiki files and database

  mysqldump --opt xxxxx --lock-tables -p | gzip > xxxxx2014012801.sql.gz
  php ./dumpBackup.php  --full | gzip > /mediawiki-xxxxx-xmldump.xml.gz
  tar -sp -zcvf /xxxxx/mysql2014012801.tgz /xxxxx/mysql
  tar -sp -zcvf /mediawiki2014012801.tgz /xxxxx/mediawiki

4. download latest mediawiki version

  wget http://download.wikimedia.org/mediawiki/xxx/mediawiki-xxxxx.tar.gz

5. extract to correct path

  tar xzvf mediawiki-xxxxx.gz -C /xxxxx/

6. copy/overwrite some config files

  ln -s mediawiki-xxxxx mediawiki
  cp mediawiki-xxxxx/LocalSettings.php ./mediawiki
  cp -r /xxxxx/mediawiki-xxxxx/images /xxxxx/mediawiki
  xxxxx
  cp -r /xxxxx/mediawiki-xxxxx/extensions /xxxxx/mediawiki (answer "no" to overwrite individual files)
      (the update.php script wouldn't work without copying these extensions first)

7. Run the update script

  php /xxxxx/mediawiki/maintenance/update.php     (this will take awhile)

8. Unlock the wiki

  vi /xxxxx/mediawiki/LocalSettings.php

  remove the line:
  $wgReadOnly = 'Dumping Database, Access will be restored shortly';

9. Once the upgrade has been completed, browse to the wiki and check that the following operations work as expected:

  Viewing pages
  Editing pages
  Uploading a file
  Visit Special:Version and check that the version shown is correct and that the extensions are present.

Testing
