INTRODUCTION ============ This file describes the basic steps to install RoundCube Webmail on your web server. For additional information, please also consult the project's wiki page at http://trac.roundcube.net/wiki REQUIREMENTS ============ * The Apache or Lighttpd Webserver * .htaccess support allowing overrides for DirectoryIndex * PHP Version 5.2 or greater including - PCRE, DOM, JSON, XML, Session, Sockets (required) - libiconv (recommended) - mbstring, fileinfo, mcrypt (optional) * PEAR packages distributed with Roundcube or external: - MDB2 2.5.0 or newer - Mail_Mime 1.6.0 or newer - Net_SMTP 1.4.2 or newer * php.ini options (see .htaccess file): - error_reporting E_ALL & ~E_NOTICE (or lower) - memory_limit > 16MB (increase as suitable to support large attachments) - file_uploads enabled (for attachment upload features) - session.auto_start disabled - zend.ze1_compatibility_mode disabled - suhosin.session.encrypt disabled - mbstring.func_overload disabled * PHP compiled with OpenSSL to connect to IMAPS and to use the spell checker * A MySQL (4.0.8 or newer), PostgreSQL, MSSQL database engine or the SQLite extension for PHP * 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") }
