Description Michael Kornhuber 2006-01-01 17:55:41 UTC
I'm using: XP SP1, EasyPHP1-8, Mediawiki-1.5.4, HDD is NTFS-formatted
I installed according to "A very simple installation for Mediawiki on your PC" found in 
"http://meta.wikimedia.org/wiki/Newcomers_guide_to_installing_on_Windows"
EasyPHP is running: apache and mysql is shown started (green traffic light)

When I lauch the Webbrowser Opera (ver 8.5 Build 7700) or InternetExplorer (ver 6.0.2800.
1106.xpsp1) and go to "C:\Programme\EasyPHP1-8\www\mediawiki-1.5.4" I just see which 
files are in the directory. gone to subdirectory "/config" there's just "index.php"
Opening it, it shows a long text including message "Can't write config file, aborting". I 
set the attributes of the whole directory (including the files) to writable, but there's 
no "LocalSettings.php" created. Is it a bug, that there's no such file created? What 
could be my mistake, if not? 

Regarding the other reported errors: the 2 magic_quotes_xxx are "OFF" in my inifile "C:
\Programme\EasyPHP1-8\php\php.ini" but reported as "active". Why are they active then?

Thanks for help!
Michael

Can't write config file, aborting

In order to configure the wiki you have to make the config subdirectory writable by the 
web server. Once configuration is done you'll move the created LocalSettings.php to the 
parent directory, and for added safety you can then remove the config subdirectory 
entirely.

To make the directory writable on a Unix/Linux system:

cd /path/to/wiki
chmod a+w config

Site config
Your site name should be a relatively short word. It'll appear as the namespace name for 
'meta' pages as well as throughout the user interface. Good site names are things like 
"Wikipedia" and "OpenFacts"; avoid punctuation, which may cause problems. 
This will be used as the return address for password reminders and may be displayed in 
some error conditions so visitors can get in touch with you. It is also be used as the 
default sender address of e-mail notifications (enotifs). 
Language
 
You may select the language for the user interface of the wiki... Some localizations are 
less complete than others. Unicode (UTF-8 encoding) is used for all localizations. 
Copyright/license metadata
Select one:
ScriptPath}/config/index.php?License=cc&RightsUrl=[license_url]&RightsText=[license_name]
&RightsCode=[license_code]&RightsIcon=[license_button]" ); $icon = urlencode( 
"$wgServer$wgUploadPath/wiki.png" ); $ccApp = htmlspecialchars( "http://creativecommons.
org/license/?partner=$partner&exit_url=$exit&partner_icon_url=$icon" ); print "choose"; ?
> (link will wipe out any other data in this form!) License == "cc" ) { ?> 
RightsIcon ) . "\" alt='icon' />", "hidden" ); ?>
RightsText ), "hidden" ); ?>
RightsCode ), "hidden" ); ?>
RightsUrl ) . "\">" . htmlspecialchars( $conf->RightsUrl ) . "", "hidden" ); ?>
MediaWiki can include a basic license notice, icon, and machine-readable copyright 
metadata if your wiki's content is to be licensed under the GNU FDL or a Creative Commons 
license. If you're not sure, leave it at "none". 
A sysop user account can lock or delete pages, block problematic IP addresses from 
editing, and other maintenance tasks. If creating a new wiki database, a sysop account 
will be created with the given name and password. 
Shared memory caching
Select one:
turck ) { echo "
"; aField( $conf, "Shm", "Turck MMCache", "radio", "turck" ); echo "
"; } ?> eaccel ) { echo "
"; aField( $conf, "Shm", "eAccelerator", "radio", "eaccel" ); echo "
"; } ?> 
Using a shared memory system such as Turck MMCache, eAccelerator, or Memcached will speed 
up MediaWiki significantly. Memcached is the best solution but needs to be installed. 
Specify the server addresses and ports in a comma-separted list. Only use Turck shared 
memory if the wiki will be running on a single Apache server. 
E-mail, e-mail notification and authentication setup
E-mail (general)
Select one:
Use this to disable all e-mail functions (send a password reminder, user-to-user e-mail 
and e-mail notification), if sending e-mails on your server doesn't work. 
User-to-user e-mail
Select one:
Use this to disable only the user-to-user e-mail function (EmailUser). 
E-mail notification
Select one:

E-mail notification sends a notification e-mail to a user, when the user_talk page is 
changed and/or when watch-listed pages are changed, depending on the above settings. When 
testing this feature, be reminded, that obviously an e-mail address must be present in 
your preferences and that your own changes never trigger notifications to be sent to 
yourself.

Users get corresponding options to select or deselect in their users' preferences. The 
user options are not shown on the preference page, if e-mail notification is disabled.

There are additional options for fine tuning in /includes/DefaultSettings.php .
E-mail address authentication
Select one:

E-mail address authentication uses a scheme to authenticate e-mail addresses of the 
users. The user who initially enters or changes his/her stored e-mail address gets a link 
with a token mailed to that address. The stored e-mail address is authenticated at the 
moment the user comes back to the wiki via the link.

The e-mail address stays authenticated as long as the user does not change it; the time 
of authentication is indicated on the user preference page.

If the option is enabled, only authenticated e-mail addresses can receive EmailUser mails 
and/or e-mail notification mails.
Database config
If your database server isn't on your web server, enter the name or IP address here. 
If you only have a single user account and database available, enter those here. If you 
have database root access (see below) you can specify new accounts/databases to be 
created. 

If you need to share one database between multiple wikis, or MediaWiki and another web 
application, you may choose to add a prefix to all the table names to avoid conflicts.

Avoid exotic characters; something like mw_ is good.
Database charset
Select one:
EXPERIMENTAL: You can enable explicit Unicode charset support for MySQL 4.1 and 5.0 
servers. This is not well tested and may cause things to break. If upgrading an older 
installation, leave in backwards-compatible mode. 
You will only need this if the database and/or user account above don't already exist. Do 
not type in your machine's root password! MySQL has its own "root" user with a separate 
password. (It might even be blank, depending on your configuration.) 
 
 
Installation successful! 

To complete the installation, please do the following: 
Download config/LocalSettings.php with your FTP client or file manager
Upload it to the parent directory
Delete config/LocalSettings.php
Start using your wiki! 

If you are in a shared hosting environment, do not just move LocalSettings.php remotely. 
LocalSettings.php is currently owned by the user your webserver is running under, which 
means that anyone on the same server can read your database password! Downloading it and 
uploading it again will hopefully change the ownership to a user ID specific to you.
EOT; } else { echo "

Installation successful! Move the config/LocalSettings.php file into the parent 
directory, then follow this link to your wiki.
