mod_mono(8) ASP.NET Support for Apache mod_mono(8) 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 ar- gument that is the mod-mono-server instance alias for which the direc- tive applies. If only one argument is provided for them, thr directive will apply to the 'default' mod-mono-server instance. Refer to the mon- odoc 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-restart- ing. The value here is taken into account only when MonoAu- toRestartMode 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 compat- ibility purposes. Default value: "/usr/bin/mono" MonoPath This value will be used to set the MONO_PATH environment vari- able. 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 ser- vice 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" direc- tory 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 --appli- cations 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, MonoAppli- cationsConfigFile 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. De- fault 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 re- quests specified by MonoMaxActiveRequests. Requests that can't be processed or held are dropped with Service Unavailable. De- fault value: 150. MonoCheckHiddenFiles Do not protect hidden files/directories from being accessed by clients. Hidden files/directories are those with Hidden at- tribute on Windows and whose name starts with a dot on Unix. Any file/directory below a hidden directory is inacessible. This op- tion turns the default behavior of protecting such locations off. If your application does not contain any hidden files/di- rectories, 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: Mono- ServerCheckHiddenFiles. 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 exam- ples. 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 con- trol 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.
