aka:Mediawiki:Install/Uninstall

インストール

とりあえず、ubuntuのパッケージでインストール
- https://help.ubuntu.com/community/MediaWiki
- http://ubuntuguide.org/wiki/MediaWiki_tips
- 課題: Ubuntuパッケージで入れたMediawikiで、複数Mediawikiサイトを立てられるか
  - 立てられる。
  - http://www.fukudat.com/wiki/ja/mediawiki
  - このサイトにあるとおりやってみる。
    - うまくいかなかった。おそらく、すでに/var/lib/mediawiki/を使ってMediawikiサイトをひとつ作ってしまったからだと思う。具体的には、http://<fqdn>/wiki/ja にブラウザでアクセスするとhttp://<fqdn>/mediawiki/ 以下にリダイレクトされてしまった。

Mediawikiについては、Ubuntuのパッケージを使わずにインストール

http://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Ubuntu

まずLAMPを構成する。ここはUbuntuのパッケージを使う。

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

setting since version 1.2.0. If you have it on, turn it '''off''' if you can.

2012-03-21

This is a maintenance and security release of the MediaWiki 1.18 branch.

Mediawikiの配置

$ pwd
/home/aka/repos
$ sudo cp -pR core /var/lib/wiki1
[sudo] password for aka: 
$

PHPの設定

/etc/php5/apache2/php.ini を調整。

調整例

max_execution_time = 300
upload_max_filesize = 80M
memory_limit = 128M

Apacheの設定
- /etc/apache2/sites-available/default を調整。
- 調整例
```
    Alias /wiki1 /var/lib/wiki1
```
Mediawikiの設定
- テキストブラウザで設定してみようとしたが、うまくいかなかった。
  - elinks: フィールド間のカーソル移動がおかしくて、編集したいフィールドにあたらない。
  - lynx: css+javascriptを使った部分のUIの表示がくずれていて、どこで何を入力したらいいのかわからなくなる。
- 結局普通のブラウザで設定。
- 設定例
  - Database name: wiki1
  - Database user name: wiki1user
  - Name of wiki: wiki1
- 設定後、LocalSetting.phpが生成されて、ブラウザにてDLされる。それを移設。
```
$ sudo mv LocalSettings.php /var/lib/wiki1/
[sudo] password for aka: 
$ 
```
- これでとりあえずMediawikiが動いた。

多少のセキュリティ

Apacheの設定

ベーシック認証をかける。

/etc/apache2/sites-available/default に以下を追加。

        <Directory "/var/lib/wiki1">
                AuthType Basic
                AuthName darkness
                AuthUserFile /usr/www/users
                Require user aka
        </Directory>

Mediawikiの設定

LoalSettings.php

参考: http://ubuntuguide.org/wiki/MediaWiki_tips#Editing_the_LocalSettings.php_configuration_file

管理者だけがユーザを作成できるようにする。

#User restrictions
#Account creation by anonymous users
$wgGroupPermissions['*']['createaccount'] = false;
#Account creation by registered users
$wgGroupPermissions['user']['createaccount'] = false;
#Account creation by sysops
$wgGroupPermissions['sysop']['createaccount'] = true;

匿名ユーザによる編集を禁止する。

#Anonymous user permissions
$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['*']['createpage'] = false;
$wgGroupPermissions['*']['createtalk'] = false;

ファイルアップロードの調整。

#Uploads rules
## To enable image uploads, make sure the 'images' directory
## is writable, then set this to true:
#$wgEnableUploads       = false;
$wgEnableUploads = true;
#Only allow restricted uploads
$wgCheckFileExtensions = true;
$wgStrictFileExtensions = true;
$wgFileExtensions = array('png', 'gif', 'jpg'); 
#Permissions for uploads
#Not for Anonymous
$wgGroupPermissions['*']['upload'] = false;
$wgGroupPermissions['*']['reupload'] = false;
$wgGroupPermissions['*']['reupload-shared'] = false;
#Uploads (but not re-uploads) for Users
$wgGroupPermissions['user']['upload'] = true;
$wgGroupPermissions['user']['reupload']        = false;
$wgGroupPermissions['user']['reupload-shared'] = false;
#Sysops
$wgGroupPermissions['sysop']['upload'] = true;
$wgGroupPermissions['sysop']['reupload'] = true;
$wgGroupPermissions['sysop']['reupload-shared'] = true;

アンインストール
- Ubuntuのパッケージでいれたものをアンインストール
  - 次のコマンドにて。
```
$ sudo aptitude remove mediawiki mediawiki-math mediawiki-extensions
```
    - 設定ファイルも消すときはpurge。
  - MySQLデータベースファイルも消す場合は、
```
$ sudo aptitude purge mysql-server-5.1
```
