NAME
mod_mono - apache module that enables ASP.NET pages. Works together with mod-mono-
server.exe
DESCRIPTION
mod_mono is a simple module that works with Apache 2.0 or newer.
It needs mod-mono-server.exe installed on the system. By default, it will attemp to run
mod-mono-server.exe if it doesn't find it's running.
CONFIGURATION DIRECTIVES
All the directives but MonoSetServerAlias accept an optional first argument that is the
mod-mono-server instance alias for which the directive applies. If only one argument is
provided for them, thr directive will apply to the 'default' mod-mono-server instance.
Refer to the monodoc documentation on configuring mod_mono for more examples.
MonoUnixUmask
It accepts an octal number as a parameter. The number must be a valid unix file
creation mask value (see umask(2)). The mask will be applied whenever a directory
or file is created from within an ASP.NET application. Default value: "0077".
MonoUnixSocket
It accepts a file name as argument. That file will be a named pipe used to
send/receive data from/to mod_mono to/from mod-mono-server. You cannot use
MonoListenPort and MonoUnixSocket at the same time. Default value:
"/tmp/mod_mono_server".
MonoListenPort
TCP port on which mod-mono-server should listen/is listening on. Mutually exclusive
with MonoUnixSocket. When this options is specified, mod-mono-server and mod_mono
will use a TCP socket for communication. Default value: none
MonoListenBacklog N
The backlog of connections to set on the listener socket in mod-mono-server. By
default the value is set to 500.
MonoMinThreads N
The minimum number of threads the threadpool allocates in mod-mono-server.
Increase this value to better handle the sudden arrival of connections. The
default value is determined by the mono runtime.
MonoListenAddress
IP address where mod-mono-server should listen/is listening on. Can only be used
when MonoListenPort is specified. Default value: "127.0.0.1"
MonoRunXSP
If the value is True, it tells mod_mono to spawn mod-mono-server.exe if it's not
already running. If set to False, most of these directives are useless. Default
value: True
MonoXSPStartAttempts
Number of times mod_mono will attempt to start a backend which died. Value cannot
be lower than 0. Default value: 3
MonoXSPStartWaitTime
Number of seconds to wait after starting the backend. This is to let the backend
initialize properly before attempting to connect to it. Value cannot be lower than
2. Default value: 2
MonoAutoRestartMode
Set the auto-restart mode for the backend(s). Three modes are available: None - do
not auto-restart, Requests - restart after a configured number of requests served,
Time - restart after the backend has been up for the specified period of time.
Note that if you enable auto-restart you should consider using off-process state
server, since on every restart your application state will be lost. Default value:
None
MonoAutoRestartRequests
Number of requests for a backend to serve before auto-restarting. The value here is
taken into account only when MonoAutoRestartMode is set to Requests. Default
value: 10000
MonoAutoRestartTime
Time after which the backend should be auto-restarted. The time format is:
DD[:HH[:MM[:SS]]]. Default value: 00:12:00:00
MonoExecutablePath (Obsoleted, ignored)
Don't use this. It is ignored and has been left here for compatibility purposes.
Default value: "/usr/bin/mono"
MonoPath
This value will be used to set the MONO_PATH environment variable. Default value:
""
MonoServerPath
The full path to the mod-mono-server script. Default value: "/usr/bin/mod-mono-
server"
MonoTargetFramework
If MonoRunXSP is True, this option selects the .NET framework version to use. This
affects the backend that is started to service the requests. The MonoServerPath
option takes precedence over this setting. Available values are "2.0", "3.5" and
"4.0". Default value: "2.0"
MonoWapiDir
The directory where mono runtime will create the ".wapi" directory used to emulate
windows I/O. It's used to set MONO_SHARED_DIR. Default value: "/tmp"
MonoDocumentRootDir
The directory passed in --root argument when launching mod-mono-server.
MonoMaxCPUTime
If MonoRunXSP is True, CPU time limit in seconds allowed for the spawned mono
process. Beyond that, it will be restarted. If this capability is not available on
your system, the directive will be ignored. Default value: system default
MonoMaxMemory
If MonoRunXSP is True, the maximum size of the process's data segment (data size)
in bytes allowed for the spawned mono process. It will be restarted when the limit
is reached. If this capability is not available on your system, the directive will
be ignored. Default value: system default
MonoApplications
AddMonoApplications
This value will be passed to mod-mono-server.exe in the --applications option. See
xsp(1) manual page for details.
MonoApplicationsConfigFile
The argument passed in --appconfigfile argument to mod-mono-server. Default value:
NULL.
MonoApplicationsConfigDir
The argument passed in --appconfigdir argument to mod-mono-server. Default value:
config/mod-mono-applications
Note that you must specify at least one of MonoApplications, MonoApplicationsConfigFile
and MonoApplicationsConfigDir.
MonoAutoApplication
Enables or disables automatic ASP.NET applications discovery. By default it is
enabled if you have no application configured. Otherwise, it's disabled. The
possible values are 'enabled' or 'disabled'.
MonoDebug
Runs mono in debug mode, which produces stack traces with line numbers. Default
value: False.
MonoSetServerAlias
Takes a server alias name. This is to be used inside <Directory> or <Location>.
Default value: 'default' if the directive is not used.
MonoSetEnv
Takes a string of 'name=value' pairs separated by semicolons. For each pair, it
calls setenv (name, value) before running mod-mono-server.
MonoIOMAP
Takes alias name and a string of the same format and meaning as the MONO_IOMAP
environment variable (see the mono(1) manpage). The effect is that mod_mono
performs the same actions as mono runtime with MONO_IOMAP in effect, as well as
that the MONO_IOMAP variable with the specified value is exported in the backend
environment. This option is necessary when you're using MONO_IOMAP in your
application and there might be static files with mixed case names - in such case
mod_mono attempts to open the file directly and sends it using apache facilities.
Default value: none
MonoMaxActiveRequests
The maximum number of concurrent requests mod_mono will pass off to the ASP.NET
backend. Set to zero to turn off the limit. Default value: 0.
MonoMaxWaitingRequests
The maximum number of concurrent requests mod_mono will hold while the ASP.NET
backend is busy with the maximum number of requests specified by
MonoMaxActiveRequests. Requests that can't be processed or held are dropped with
Service Unavailable. Default value: 150.
MonoCheckHiddenFiles
Do not protect hidden files/directories from being accessed by clients. Hidden
files/directories are those with Hidden attribute on Windows and whose name starts
with a dot on Unix. Any file/directory below a hidden directory is inacessible.
This option turns the default behavior of protecting such locations off. If your
application does not contain any hidden files/directories, you might want to use
this option as the checking process has a per-request cost. Accepts a boolean value
- 'true' or 'false' Default value: true. AppSettings key name:
MonoServerCheckHiddenFiles.
SAMPLE VIRTUAL HOST CONFIGURATION
Note that the configuration below requires the mod_mono module to be loaded by Apache. How
it is done is distribution-specific - please check your distribution documentation for
details.
This one using <Directory>:
Alias /mono "/usr/lib/xsp/test"
AddMonoApplications default "/mono:/usr/lib/xsp/test"
<Directory /usr/lib/xsp/test>
SetHandler mono
<IfModule mod_dir.c>
DirectoryIndex index.aspx
</IfModule>
</Directory>
This one using <Location>:
Alias /demo "/usr/lib/xsp/test"
AddMonoApplications default "/demo:/usr/lib/xsp/test"
<Location /demo>
SetHandler mono
</Location>
If you prefer to .webapp configuration file(s) (see manual page of xsp), you can change
MonoApplications in the above samples by:
MonoApplicationsConfigFile default "/var/www/applications.webapp"
replacing the path to the file with yours.
If you want to use several .webapp files, use this instead:
MonoApplicationsConfigDir default "/var/www/webapp"
and all the .webapp files found in the directory /var/www/webapp will be loaded.
Refer to monodoc documentation on configuring mod_mono for more examples.
THE MOD_MONO CONTROL PANEL
mod_mono provides a simple web-based control panel for restarting the mod-mono-server,
which is useful when assemblies need to be reloaded from disk after they have been
changed. To activate the control panel, place the following in your httpd.conf:
<Location /mono>
SetHandler mono-ctrl
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
The control panel is then accessible at http://yourdomain.com/mono. Clicking the link to
restart mod-mono-server will immediately restart it.
The Order/Deny/Allow access controls above restrict access to the control panel to the
computer with IP address 127.0.0.1. Replace this (or add more Allow lines) with the IP
address of your own computer so that you can access the control panel. You can also use
Apache's htaccess features to password protect it, too.
ENVIRONMENT VARIABLES
It may modify MONO_PATH, PATH and MONO_SHARED_DIR when starting mod-mono-server.
The MOD_MONO_CCV variable may be used to select which component will do client certificate
validity (CCV) checks. By default both Apache and Mono will verify the client
certificates. This can be changed to either "apache" or "mono" to limit the validity check
to either environment. This variable can be set using MonoSetEnv to allow different vhost
to use separate validation techniques.
The MOD_MONO_LOCKING_MECHANISM variable may be used to choose the APR locking mechanism
for the dashboard. The currently defined mechanism names are: DEFAULT, FCNT, FLOCK,
SYSVSEM, PROC_PTHREAD, POSIXSEM. Note that not every mechanism may be available for your
platform. In such case, mod_mono will fallback to using the DEFAULT value which lets the
APR decide which locking mechanism to use. DEFAULT is also the default value for the
option if the environment variable is not set or its value is unknown. This value MUST NOT
be set using MonoSetEnv - it MUST be present in the Apache environment before the module
is initialized and its configuration parsed.
