#### Quick setup
Setup apache to point to /usr/share/wordpress. See the examples/apache.conf
Database and filesystem setup can be done with the help of a script in
examples/setup-mysql. Beware: it assumes that you want to install your
files in /srv/www/.
#### WordPress configuration file
The Debian package installs a wp-config.php script that will
try to load the real configuration from /etc/wordpress/config-$HOST.php
or /etc/wordpress/config-$DOMAIN.php (if the URL is "http://blog.example.com",
$HOST will be "blog.example.com" and $DOMAIN will be "example.com").
If none of those files exist, it will try /etc/wordpress/config-default.php.
Failing that, it will return an error 404.
This was initially developed to host multiple blogs on the same server
but since then, WordPress has grown a "multisite" feature of its own.
If you want to learn more about those configuration files, you should
check /usr/share/wordpress/wp-config-sample.php and
http://codex.wordpress.org/Editing_wp-config.php
#### Managing plugins, themes and uploaded files
To respect the FHS and to to let you add supplementary plugins and themes,
the default configuration sets WP_CONTENT_DIR to
/var/lib/wordpress/wp-content. This implies that your Apache configuration
should override the default wp-content directory (within the DocumentRoot)
with this directory. You can do this with an alias directive:
Alias /wp-content /var/lib/wordpress/wp-content
The subdirectories "uploads" and "blogs.dir" should be owned by www-data
by default. This ensures that you can upload media files from within
WordPress.
The subdirectories "themes" and "plugins" are where you can drop
non-packaged themes and plugins.
Note that if you want WordPress to be able to edit themes and to update
plugins, you have to ensure that all the themes and plugins are owned
by the webserver user (www-data). This is easy to do for the themes
and plugins that you have installed in /var/lib/wordpress/wp-content/:
$ sudo chown -R www-data /var/lib/wordpress/wp-content
But the default themes and plugins (installed in
/usr/share/wordpress/wp-content/) are owned by the root user. If you want
those to be editable, you should remove the corresponding symlink in
/var/lib/wordpress/wp-content/ and put there a full copy of the default
themes and plugins. Then you should re-run the previous chown command.
If despite all this, you can't get the plugin upgrade feature to work, you
can try to add the following parameter to your configuration file:
define( 'FS_METHOD', 'direct' );
#### Hosting multiple blogs
## With WordPress multisite
With WordPress multisite, you have a single instance of WordPress
(one database, one configuration file) that is able to manage multiple
blogs.
It is thus recommended to put your WordPress configuration in
/etc/wordpress/config-default.php. Then you should enable the
"Multisite" feature in the web interface directly through
Administration > Tools > Network Setup.
More information:
http://codex.wordpress.org/Create_A_Network
Note that the default configuration of the Debian package already includes
WP_ALLOW_MULTISITE set to true.
## With separate configurations
If you don't want to use the multisite feature, you can create
multiple configuration files corresponding to your various blogs.
Each configuration file can point to a dedicated MySQL database (or
they can share the same database but then they must use different
$table_prefix to ensure that they use different tables within
the same database).
#### Upgrading to a new Wordpress version
The package upgrade doesn't automatically update the Wordpress database,
you have to login to the administration page of your Wordpress instance
to complete this part of the upgrade.
Until you do this, your website might be broken and inaccessible. This is
only required when you switched to a new major release (like 3.4 → 3.5)
not when you installed a new minor version (like 3.5.1 → 3.5.2).
