+
+The Wikipedia software was developed collaboratively by
many people, so it's something of a hodgepodge. The
main wiki software itself is written in PHP, and requires
the Apache web server and MySQL database. The optional
which is required to compile them. The test suite is
written in Java, using several external libraries.
-Recommended versions are: Apache 1.3.26 or later; MySQL
-2.23.51 or later; PHP 4.2.2 or later. The installation at
-wikipedia.org also uses the APC caching software, but
+Recommended versions are: Apache 1.3.27 or later; MySQL
+4.0.13 or later; PHP 4.3.2 or later. The installation at
+wikipedia.org also uses PHP Accelerator software, but
that's entirely optional and doesn't affect anything else.
The math rendering functions are more complex, and will
runtime, and ImageMagick requires GhostScript. These are
present in most Linux distributions.

+Scripts install.php and update.php
+----
+
Before installing the software, you must copy the file
"LocalSettings.sample" to "LocalSettings.php", and
"AdminSettings.sample" to "AdminSettings.php", and
customize both of the php files to your local setup
-(things like installation parh, passwords, etc.) The
-script install.php in the maintenance directory can then
-be run to install the software.
+(things like installation path, passwords, etc.) The
+script install.php can then be run to install the
+software. It must be run from the command line with
+PHP: that is, type "php install.php" (you may need to
+specify the path the php executable). You will probably
+need to run as root.
+
+ Hint: If you are using Debian, the PHP interpreter is
+ not part of the "php4" package; you need to install
+ php4-cgi separately (the interpreter will be called
+ php4).
+
+This script will copy all the necessary software over to
+the directories you have specified in the settings files.
+It will then warn you that it is about to create the
+database and give you the chance to exit. If you are
+installing the software to an existing database, you can
+answer "no" here and it will be left alone. The software
+installation will be otherwise complete. If you do choose
+to create a new database, you will need te root password
+to your MySQL installation.
+
+If you are merely updating an existing installation, run
+"php update.php" instead of install. This will copy all
+the software, and also run any database updates that may
+be necessary. These should give appropriate warnings if
+there are any dangerous ones.

+Building from scratch
+----
Here are some more notes on building a system from scratch
the way it was done for the Wikipedia server:
Downloads:
- gcc-2.95.3.tar.gz
- mysql-3.23.51.tar.gz
+ gcc-2.95.3.tar.gz (only if you now have gcc 2.96)
+ mysql-4.0.13.tar.gz (or 3.23.57 should work)
libiconv-1.8.tar.gz
- apache_1.3.26.tar.gz
- php-4.2.1.tar.gz
+ apache_1.3.27.tar.gz
+ php-4.3.2.tar.gz
apc-cvs.tar.gz
And for math support:
- ocaml-3.06.tar.gz
+ ocaml-3.06.tar.gz (3.04 doesn't work)
(TeTeX, ImageMagick, and GhostScript come with most Linux distros)
1. MySQL strongly recommends using gcc 2.95 to compile MySQL.
- RedHat Linux comes with 2.96 by default, so you'll have to install

+ you can skip this step.
2. Install MySQL source; add "mysql" user and group. Make sure the
directory into which you installed gcc 2.95 appears before the
directory of gcc 2.96 in your path. Configure with:
- FLAGS="-O3 -mpentiumpro" CXX=gcc CXXFLAGS="-O3 -mpentiumpro -felide-constructors -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local/mysql --enable-assembler --with-mysqld-ldflags=-all-static --disable-shared --with-extra-charset=complex
+ FLAGS="-O3 -mcpu=i686" CXX=gcc CXXFLAGS="-O3 -mcpu=i686 -felide-constructors -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local/mysql --enable-assembler --with-mysqld-ldflags=-all-static --disable-shared --with-extra-charset=complex
Edit the file myisam/ftdefs.h, changing the define for minimum word
length for fulltext indexing: #define MIN_WORD_LEN 2. Update
FulltextStoplist.php from the MySQL sources if you have customized
MySQL's stop list.
+ If you are running anything other than Wikipedia itself you'll want
+ to make a lot of changes to the LanguageXX.php files so it talks about
+ _your_ site and _your_ license. :)
+
4. Optionally, install libiconv (http://www.gnu.org/software/libiconv/).
This will be used by some language packages for converting
native-charset URLs to and from UTF-8. If you're running an
- English-only wiki, this won't be necessary.
+ English-only wiki, this probably won't be necessary. (Most Linux
+ distributions should come with libiconv anyway, but check for
+ a separate 'dev' package if on RedHat.)
5. Unpack Apache distribution and begin configuring, but don't finish
build yet. Configure with something like:
- OPTIM='-O2 -mpentiumpro' ./configure --with-layout=Apache
+ OPTIM='-O2 -mcpu=i686' ./configure --with-layout=Apache
6. If you'll want to use Apache's mod_rewrite to make page-viewing URLs
look like static links (as wikipedia.org does), install the included

- ./configure --enable-apc --with-mysql=/usr/local/mysql --with-iconv=/usr/local/lib --with-apache=/home/lee/src/apache_1.3.26
+ ./configure --enable-apc --enable-shmop --with-zlib --with-zlib-dir=/usr/lib --with-mysql=/usr/local/mysql --with-iconv=/usr/local/lib --with-apache=/home/lee/src/apache_1.3.26 --with-readline=/lib --enable-sockets
+
+Or for Apache 2.0 module:
+ ./configure --enable-shmop --with-zlib --with-zlib-dir=/usr/lib --with-mysql=/usr/local/mysql --with-iconv --with-apxs2filter=/usr/local/apache/bin/apxs
(using your own local paths, of course). Build and install as
- instructed. Set "register_globals" on in the config file.

- OPTIM='-O2 -mpentiumpro' ./configure --with-layout=Apache --enable-module=rewrite --activate-module=src/modules/php4/libphp4.a
+ OPTIM='-O2 -mcpu=i686' ./configure --with-layout=Apache --enable-module=rewrite --enable-module=mmap-static --enable-module=headers --enable-module=expires --activate-module=src/modules/php4/libphp4.a
Update httpd.conf as needed for your site. For example:
(the "php_admin_flag engine off/on" directives above) to prevent
the uploading and running of malicious scripts.

- installing as a Zend extension.
