# vi conf/local.php
$conf['userewrite'] = '1';

以下のようにコメントアウトを外してあげる

## Enable this to restrict editing to logged in users only

## You should disable Indexes and MultiViews either here or in the
## global config. Symlinks maybe needed for URL rewriting.
#Options -Indexes -MultiViews +FollowSymLinks

## make sure nobody gets the htaccess, README, COPYING or VERSION files
<Files ~ "^([\._]ht|README$|VERSION$|COPYING$)">
    Order allow,deny
    Deny from all
    Satisfy All
</Files>

## Uncomment these rules if you want to have nice URLs using
## $conf['userewrite'] = 1 - not needed for rewrite mode 2

## If you enable DokuWikis XML-RPC interface, you should consider to

RewriteCond %{HTTPS} !=on
RewriteRule ^lib/exe/xmlrpc.php$      https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

RewriteRule ^_media/(.*)              lib/exe/fetch.php?media=$1  [QSA,L]
RewriteRule ^_detail/(.*)             lib/exe/detail.php?media=$1  [QSA,L]
RewriteRule ^_export/([^/]+)/(.*)     doku.php?do=export_$1&id=$2  [QSA,L]

[userwrite = 2] (Dokuwikiによる設定)から変更する場合は、元のURLリンクからたどると、全部トップページになってしまいます。

上記のURLから下のURLへ
http://dokuwiki.fl8.jp/bash/script/15_awk_for_count

下記の行を入れてあげると、元のURLもそのまま利用できます。

RewriteRule ^doku.php(.*)             doku.php?id=$1  [QSA,L]

こんな感じで

RewriteRule ^_media/(.*)              lib/exe/fetch.php?media=$1  [QSA,L]
RewriteRule ^_detail/(.*)             lib/exe/detail.php?media=$1  [QSA,L]
RewriteRule ^_export/([^/]+)/(.*)     doku.php?do=export_$1&id=$2  [QSA,L]
RewriteRule ^$                        doku.php  [L]
RewriteRule ^doku.php(.*)             doku.php?id=$1  [QSA,L]
RewriteCond %{REQUEST_FILENAME}       !-f
RewriteCond %{REQUEST_FILENAME}       !-d
RewriteRule (.*)                      doku.php?id=$1  [QSA,L]
RewriteRule ^index.php$               doku.php
