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, Lighttpd, Cherokee or Hiawatha web server * .htaccess support allowing overrides for DirectoryIndex * PHP Version 5.3.7 or greater including - PCRE, DOM, JSON, Session, Sockets, OpenSSL, Mbstring (required) - PHP Data Objects (PDO) with driver for either MySQL, PostgreSQL or SQLite (required) - Libiconv, Zip, Fileinfo (recommended) * PEAR packages distributed with Roundcube or external: - Mail_Mime 1.10.0 or newer - Net_SMTP (latest from https://github.com/pear/Net_SMTP/) - Net_IDNA2 0.1.1 or newer - Auth_SASL 1.0.6 or newer - Net_Sieve 1.3.2 or newer (for managesieve plugin) - Crypt_GPG 1.2.0 or newer (for enigma plugin) * 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 - suhosin.session.encrypt disabled - mbstring.func_overload disabled - magic_quotes_runtime disabled - magic_quotes_sybase disabled - register_globals disabled (PHP < 5.4) * PHP compiled with OpenSSL to use secure (tls/ssl) connections and to use the spell checker * A MySQL (4.0.8 or newer), PostgreSQL, MS SQL Server (2005 or newer) database engine or SQLite support in PHP * One of the above databases with permission to create tables * An SMTP server (recommended) or PHP configured for mail delivery * Composer installed either locally or globally (https://getcomposer.org) INSTALLATION ============ 1. Decompress and put this folder somewhere inside your document root 2. Install dependencies using composer: - get composer from https://getcomposer.org/download/ - rename the composer.json-dist file into composer.json - if you want to use LDAP address books, enable the LDAP libraries in your composer.json file by moving the items from "suggest" to the "require" section (remove the explanation texts after the version!). - run `php composer.phar install --no-dev` 3. Make sure that the following directories (and the files within) are writable by the webserver - /temp - /logs 4. Create a new database and a database user for Roundcube (see DATABASE SETUP) 5. Point your browser to http://url-to-roundcube/installer/ 6. Follow the instructions of the install script (or see MANUAL CONFIGURATION) 7. After creating and testing the configuration, remove the installer directory 8. Check Known Issues section of this file CONFIGURATION HINTS =================== IMPORTANT! Read all comments in defaults.inc.php, understand them and configure your installation to be not surprised by default behaviour. Roundcube writes internal errors to the 'errors' log file located in the logs directory which can be configured in config/config.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. Note: See defaults.inc.php file for examples of DSN configuration. * 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 -------- Versions of sqlite database engine older than 3 aren't supported. Database file and structure is created automatically by Roundcube. Make sure your configuration points to some file location 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 -P roundcube $ createdb -O roundcube -E UNICODE roundcubemail $ psql -U roundcube -f SQL/postgres.initial.sql roundcubemail Note: in some system configurations you might need to add '-U postgres' to createuser and createdb commands. * Microsoft SQL Server ---------------------- Language/locale of the database must be set to us_english (1033). More info on this at http://trac.roundcube.net/ticket/1488918. Database cleaning ----------------- To keep your database slick and clean we recommend to periodically execute bin/cleandb.sh which finally removes all records that are marked as deleted. Best solution is to install a cronjob running this script daily. MANUAL CONFIGURATION ==================== First of all, copy the sample configuration file config/config.inc.php.sample to config/config.inc.php and make the necessary adjustments according to your environment and your needs. More configuration options can be copied from the config/defaults.inc.php file into your local config.inc.php file as needed. Read the comments above the individual configuration options to find out what they do or read 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 SECURE YOUR INSTALLATION ======================== Access through the webserver to the following directories should be denied: /config /temp /logs Roundcube uses .htaccess files to protect these directories, so be sure to allow override of the Limit directives to get them taken into account. The package also ships a .htaccess file in the root directory which defines some rewrite rules. In order to properly secure your installation, please enable mod_rewrite for Apache webserver and double check access to the above listed directories and their contents is denied. NOTE: In Apache 2.4, support for .htaccess files has been disabled by default. Therefore you first need to enable this in your Apache main or virtual host config by with: AllowOverride all 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") } KNOWN ISSUES ============ Installations with uw-imap server should set imap_disabled_caps = array('ESEARCH') in main configuration file. ESEARCH implementation in this server is broken (#1489184).
