-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.

authentication = "internal_hashed"

-- 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" (Note: "sql" requires installed
-- lua-dbi RPM package)

-- 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


-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
    -- Log everything of level "info" and higher (that is, all except "debug" messages)
    -- to /var/log/prosody/prosody.log and errors also to /var/log/prosody/prosody.err
    info = "/var/log/prosody/prosody.log"; -- Change 'info' to 'debug' for verbose logging
    error = "/var/log/prosody/prosody.err"; -- Log errors also to file
    -- error = "*syslog"; -- Log errors also to syslog
    -- "*console"; -- Log to the console, useful for debugging with daemonize=false
}


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


-- Certificates

-- Location of directory to find certificates in (relative to main config file):
certificates = "/etc/pki/prosody/"

-- HTTPS currently only supports a single certificate, specify it here:
--https_certificate = "/etc/prosody/certs/localhost.crt"

-- POSIX configuration
-- For more info see https://prosody.im/doc/modules/mod_posix
pidfile = "/run/prosody/prosody.pid";
--daemonize = false -- Default is "true"


----------- 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 "example.com"
--    certificate = "/path/to/example.crt"

----------- Virtual host: foo.net  -----------

VirtualHost "foo.net"

-- XEP-0045 Multi User Chat
Component "conference.foo.net" "muc"
    name = "The foo.net chatrooms server"
    restrict_room_creation = false

modules_enabled = {
    "muc_mam", -- XEP-0313: Message Archive Management (Multi-User Chat)
    "vcard_muc" -- XEP-0153 vCard-Based avatar
}

-- XEP-0363: HTTP File Upload
Component "upload.foo.net" "http_file_share"

http_file_share_daily_quota = 1024 * 1024 * 200 -- 500 MB
http_file_share_expires_after = 60 * 60 * 24 * 7 -- a week in seconds


----------- Virtual host: bar.net -----------

    name = "The bar.net chatrooms server"

------ Additional config files ------
-- For organizational purposes you may prefer to add VirtualHost and
-- Component definitions in their own config files. This line includes
-- all config files in /etc/prosody/conf.d/

-- Include "conf.d/*.cfg.lua"
