UbuntuServer Apache2.4 DocumentRoot変更とモジュール有効化

デフォルトのDocumentRootが/var/www/htmlだったので
/etc/apache.confに「DocumentRoot /var/www」と書き込んでみたが適応されない。
mod_rewriteも適応させようとLoadModuleを/etc/apache.confに書き込んでみたけど適応しない。
うーむ2.2から2.4でちょっとした仕様変更があったようです。

• 設定ファイルのディレクトリ構造

# ls /etc/apache2/


apache2.conf  conf-available/  conf-enabled/
envvars  magic  mods-available/  mods-enabled/  ports.conf
sites-available/  sites-enabled/


*-available/に利用可能な設定ファイルなどが入っており、
*-enabled/にそのファイルのリンクを張ることで有効化されるという形のようです。
とりあえずやってみましょう。


• DocumentRootの変更

sites-available/000-default.confを改変してsites-enabledにリンクを張ります。
# cd /etc/apache2/
# vi sites-available/000-default.conf


<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>


# ln -s /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-enabled/


• mod_rewriteの適応

# cd /etc/apache2

有効なmodsとやらを覗いてみると.loadやら.confやら
# ls mods-available

ファイルの中身を覗いてみる
# cat mods-available/rewrite.load


LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so


これは2.2までapache.confに書き込んでいた書式ですね。

modsを有効化するにはsitesと同じくmods-availableからmods-enabledにリンクを張ればおｋ
# ln -s /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/

そして再起動で適応
# service apache2 restart
