Example configuration file for Prosody

Below is the example configuration file included in the Prosody source releases. Adapt and modify to suit, according to the list of options in the main configuration page.

⚠️ It is recommended to use the configuration file provided with the packages for your platform, if possible, as they may contain ready-configured default options specific to your platform.

-- Prosody Example Configuration File
--
-- If it wasn't already obvious, -- starts a comment, and all 
-- text after it on a line is ignored by Prosody.
--
-- The config is split into sections, a global section, and one 
-- for each defined host that we serve. You can add as many host 
-- sections as you like.
--
-- Lists are written
_ = { "like", "this", "one" } 
-- Lists can also be of { 1, 2, 3 } numbers, etc. 
-- Either commas, or semi-colons; may be used
-- as separators.
--
-- A table is a list of values, except each value has a name. An 
-- example would be:
--
example_ssl = { key = "keyfile.key", certificate = "certificate.crt" }
--
-- Whitespace (that is tabs, spaces, line breaks) is mostly insignificant, so 
-- can 
-- be placed anywhere
-- that   you deem fitting.
--
-- Tip: You can check that the syntax of this file is correct
-- when you have finished by running this command:
--     prosodyctl check config
-- If there are any errors, it will let you know what and where
-- they are, otherwise it will keep quiet.
--
-- The only thing left to do is rename this file to remove the .dist ending, and fill in the
-- blanks. Good luck, and happy Jabbering!


---------- Server-wide settings ----------
-- Settings in this section apply to the whole server and are the default settings
-- for any virtual hosts

-- This is a (by default, empty) list of accounts that are admins
-- for the server. Note that you must create the accounts separately
-- (see https://prosody.im/doc/creating_accounts for info)
-- Example: admins = { "user1@example.com", "user2@example.net" }
admins = { }

-- This option allows you to specify additional locations where Prosody
-- will search first for modules. For additional modules you can install, see
-- the community module repository at https://modules.prosody.im/
--plugin_paths = {}

-- This is the list of modules Prosody will load on startup.

-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled = {
    -- "offline"; -- Store offline messages
    -- "c2s"; -- Handle client connections
    -- "s2s"; -- Handle server-to-server connections
    -- "posix"; -- POSIX functionality, sends server to background, etc.
}


-- Server-to-server authentication
-- Require valid certificates for server-to-server connections?
-- If false, other methods such as dialback (DNS) may be used instead.

s2s_secure_auth = true

-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using other methods instead,
-- even when s2s_secure_auth is enabled.

--s2s_insecure_domains = { "insecure.example" }

-- Even if you disable s2s_secure_auth, you can still require valid
-- certificates for some domains by specifying a list here.

--s2s_secure_domains = { "jabber.org" }


-- Rate limits
-- Enable rate limits for incoming client and server connections. These help
-- protect from excessive resource consumption and denial-of-service attacks.

limits = {
    c2s = {
        rate = "10kb/s";
    };
    s2sin = {
        rate = "30kb/s";
    };
}

-- Authentication
-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.
-- For more information see https://prosody.im/doc/authentication

authentication = "internal_hashed"

-- Many authentication providers, including the default one, allow you to
-- create user accounts via Prosody's admin interfaces. For details, see the
-- documentation at https://prosody.im/doc/creating_accounts


-- Storage
-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.

--storage = "sql" -- Default is "internal"

-- For the "sql" backend, you can uncomment *one* of the below to configure:
--sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }


-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.

archive_expires_after = "1w" -- Remove archived messages after 1 week

-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam


-- Audio/video call relay (STUN/TURN)
-- To ensure clients connected to the server can establish connections for
-- low-latency media streaming (such as audio and video calls), it is
-- recommended to run a STUN/TURN server for clients to use. If you do this,
-- specify the details here so clients can discover it.
-- Find more information at https://prosody.im/doc/turn

-- Specify the address of the TURN service (you may use the same domain as XMPP)
--turn_external_host = "turn.example.com"

-- This secret must be set to the same value in both Prosody and the TURN server
--turn_external_secret = "your-secret-turn-access-token"


-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
    info = "prosody.log"; -- Change 'info' to 'debug' for verbose logging
    error = "prosody.err";
    -- "*syslog"; -- Uncomment this for logging to syslog
    -- "*console"; -- Log to the console, useful for debugging when running in the foreground
}


-- Uncomment to enable statistics
-- For more info see https://prosody.im/doc/statistics
-- statistics = "internal"


-- Certificates
-- Every virtual host and component needs a certificate so that clients and
-- servers can securely verify its identity. Prosody will automatically load
-- certificates/keys from the directory specified here.
-- For more information, including how to use 'prosodyctl' to auto-import certificates
-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates

-- Location of directory to find certificates in (relative to main config file):
certificates = "certs"

----------- Virtual hosts -----------
-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
-- Settings under each VirtualHost entry apply *only* to that host.

VirtualHost "localhost"
-- Prosody requires at least one enabled VirtualHost to function. You can
-- safely remove or disable 'localhost' once you have added another.


--VirtualHost "example.com"

------ Components ------
-- You can specify components to add hosts that provide special services,
-- like multi-user conferences, and transports.
-- For more information on components, see https://prosody.im/doc/components

---Set up a MUC (multi-user chat) room server on conference.example.com:
--Component "conference.example.com" "muc"
--- Store MUC messages in an archive and allow users to access it
--modules_enabled = { "muc_mam" }

---Set up a file sharing component
--Component "share.example.com" "http_file_share"

---Set up an external component (default component port is 5347)
--
-- External components allow adding various services, such as gateways/
-- bridges to non-XMPP networks and services. For more info
-- see: https://prosody.im/doc/components#adding_an_external_component
--
--Component "gateway.example.com"
--  component_secret = "password"


---------- End of the Prosody Configuration file ----------
-- You usually **DO NOT** want to add settings here at the end, as they would
-- only apply to the last defined VirtualHost or Component.
--
-- Settings for the global section should go higher up, before the first
-- VirtualHost or Component line, while settings intended for specific hosts
-- should go under the corresponding VirtualHost or Component line.
--
-- For more information see https://prosody.im/doc/configure
