* One of the above databases with permission to create tables
|
* An SMTP server (recommended) or PHP configured for mail delivery
|
|
|
INSTALLATION
|
============
|
|
1. Decompress and put this folder somewhere inside your document root
|
2. Make sure that the following directories (and the files within)
|
are writable by the webserver
|
- /temp
|
- /logs
|
3. Create a new database and a database user for RoundCube (see DATABASE SETUP)
|
4. Point your browser to http://url-to-roundcube/installer/
|
5. Follow the instructions of the install script (or see MANUAL CONFIGURATION)
|
6. After creating and testing the configuration, remove the installer directory
|
7. Done!
|
|
|
CONFIGURATION HINTS
|
===================
|
|
RoundCube writes internal errors to the 'errors' log file located in the logs
|
directory which can be configured in config/main.inc.php. If you want ordinary
|
PHP errors to be logged there as well, enable the 'php_value error_log' line
|
in the .htaccess file and set the path to the log file accordingly.
|
|
By default the session_path settings of PHP are not modified by Roundcube.
|
However if you want to limit the session cookies to the directory where
|
Roundcube resides you can uncomment and configure the according line
|
in the .htaccess file.
|
|
|
DATABASE SETUP
|
==============
|
|
Note: Database for RoundCube must use UTF-8 character set.
|
|
* MySQL
|
-------
|
Setting up the mysql database can be done by creating an empty database,
|
importing the table layout and granting the proper permissions to the
|
roundcube user. Here is an example of that procedure:
|
|
# mysql
|
> CREATE DATABASE roundcubemail /*!40101 CHARACTER SET utf8 COLLATE utf8_general_ci */;
|
> GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost
|
IDENTIFIED BY 'password';
|
> quit
|
|
# mysql roundcubemail < SQL/mysql.initial.sql
|
|
Note 1: 'password' is the master password for the roundcube user. It is strongly
|
recommended you replace this with a more secure password. Please keep in
|
mind: You need to specify this password later in 'config/db.inc.php'.
|
|
|
* SQLite
|
--------
|
You need sqlite 2 (preferably 2.8) to setup the sqlite db
|
(sqlite 3.x also doesn't work at the moment). Here is
|
an example how you can setup the sqlite.db for roundcube:
|
|
# sqlite -init SQL/sqlite.initial.sql sqlite.db
|
Loading resources from SQL/sqlite.initial.sql
|
SQLite version 2.8.16
|
Enter ".help" for instructions
|
sqlite> .exit
|
# chmod o+rw sqlite.db
|
|
Make sure your configuration points to the sqlite.db file and that the
|
webserver can write to the file and the directory containing the file.
|
|
|
* PostgreSQL
|
------------
|
To use RoundCube with PostgreSQL support you have to follow these
|
simple steps, which have to be done as the postgres system user (or
|
which ever is the database superuser):
|
|
$ createuser roundcube
|
$ createdb -O roundcube -E UNICODE roundcubemail
|
$ psql roundcubemail
|
|
roundcubemail =# ALTER USER roundcube WITH PASSWORD 'the_new_password';
|
roundcubemail =# \c - roundcube
|
roundcubemail => \i SQL/postgres.initial.sql
|
|
All this has been tested with PostgreSQL 8.x and 7.4.x. Older
|
versions don't have a -O option for the createdb, so if you are
|
using that version you'll have to change ownership of the DB later.
|
|
|
MANUAL CONFIGURATION
|
====================
|
|
First of all, rename the files config/*.inc.php.dist to config/*.inc.php.
|
You can then change these files according to your environment and your needs.
|
Details about the config parameters can be found in the config files.
|
See http://trac.roundcube.net/wiki/Howto_Install for even more guidance.
|
|
You can also modify the default .htaccess file. This is necessary to
|
increase the allowed size of file attachments, for example:
|
php_value upload_max_filesize 2M
|
|
|
UPGRADING
|
=========
|
|
If you already have a previous version of RoundCube installed,
|
please refer to the instructions in UPGRADING guide.
|
|
|
OPTIMISING
|
==========
|
|
There are two forms of optimisation here, compression and caching, both aimed
|
at increasing an end user's experience using RoundCube Webmail. Compression
|
allows the static web pages to be delivered with less bandwidth. The index.php
|
of RoundCube Webmail already enables compression on its output. The settings
|
below allow compression to occur for all static files. Caching sets HTTP
|
response headers that enable a user's web client to understand what is static
|
and how to cache it.
|
|
The caching directives used are:
|
* Etags - sets at tag so the client can request is the page has changed
|
* Cache-control - defines the age of the page and that the page is 'public'
|
This enables clients to cache javascript files that don't have private
|
information between sessions even if using HTTPS. It also allows proxies
|
to share the same cached page between users.
|
* Expires - provides another hint to increase the lifetime of static pages.
|
|
For more information refer to RFC 2616.
|
|
Side effects:
|
-------------
|
These directives are designed for production use. If you are using this in
|
a development environment you may get horribly confused if your webclient
|
is caching stuff that you changed on the server. Disabling the expires
|
parts below should save you some grief.
|
|
If you are changing the skins, it is recommended that you copy content to
|
a different directory apart from 'default'.
|
|
Apache:
|
-------
|
To enable these features in apache the following modules need to be enabled:
|
* mod_deflate
|
* mod_expires
|
* mod_headers
|
|
The optimisation is already included in the .htaccess file in the top
|
directory of your installation.
|
|
If you are using Apache version 2.2.9 and later, in the .htaccess file
|
change the 'append' word to 'merge' for a more correct response. Keeping
|
as 'append' shouldn't cause any problems though changing to merge will
|
eliminate the possibility of duplicate 'public' headers in Cache-control.
|
|
Lighttpd:
|
---------
|
With Lightty the addition of Expire: tags by mod_expire is incompatible with
|
the addition of "Cache-control: public". Using Cache-control 'public' is
|
used below as it is assumed to give a better caching result.
|
|
Enable modules in server.modules:
|
"mod_setenv"
|
"mod_compress"
|
|
Mod_compress is a server side cache of compressed files to improve its performance.
|
|
$HTTP["host"] == "www.example.com" {
|
|
static-file.etags = "enable"
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Etag.use-mtimeDetails
|
etag.use-mtime = "enable"
|
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModSetEnv
|
$HTTP["url"] =~ "^/roundcubemail/(plugins|skins|program)" {
|
setenv.add-response-header = ( "Cache-Control" => "public, max-age=2592000")
|
}
|
|
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModCompress
|
# set compress.cache-dir to somewhere outside the docroot.
|
compress.cache-dir = var.statedir + "/cache/compress"
|
|
compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css", "text/xml", "image/gif", "image/png")
|
}
