The option \term{modules} defines the list of modules that will be loaded after
|
||||
\ejabberd{}'s startup. Each entry in the list is a tuple in which the first
|
||||
element is the name of a module and the second is a list of options for that
|
||||
module.
|
||||
|
||||
The option \term{modules} defines the modules that will be started
|
||||
for each virtual host, and the module options.
|
||||
The syntax is:
|
||||
\esyntax{\{modules, [ \{ModuleName, ModuleOptions\}, ...]\}.}
|
||||
|
||||
Each module is started for each virtual host with the same options.
|
||||
If you want a module to be started in a specific host with a different configuration,
|
||||
use \term{host\_config} with \term{add} as explained in section~\ref{virtualhost}.
|
||||
|
||||
If you configure ejabberd to serve millions of virtual hosts,
|
||||
you may want that each module is started only once, and let it serve all the hosts.
|
||||
Those modules are started statically when ejabberd starts,
|
||||
and cannot be reconfigured until the next server start.
|
||||
The option \term{static\_modules} defines the modules that will be started statically.
|
||||
The syntax is:
|
||||
\esyntax{\{static\_modules, [ \{ModuleName, ModuleOptions\}, ...]\}.}
|
||||
|
||||
Examples:
|
||||
\begin{itemize}
|
||||
\item In this example only the module \modecho{} is loaded and no module
|
||||
options are specified between the square brackets:
|
||||
\item Start three modules for each vhost.
|
||||
They can be reconfigured or stopped dynamically, for example with WebAdmin.
|
||||
Remark that, besides the last entry, all entries end with a comma:

{mod_time, []},

{mod_version, []}
|
||||
]}.
|
||||
\end{verbatim}
|
||||
\item In the second example the modules \modecho{}, \modtime{}, and
|
||||
\modversion{} are loaded without options. Remark that, besides the last entry,
|
||||
all entries end with a comma:
|
||||
\item Start MUC for each vhost, and the other three modules for all the vhosts:
