Installing mod-mono on CentOS

[proxies]

I am very new in linux environment as well as mod_mono. I installed mod mono on a CentOS server and it seems that I am having problem. I follow the step by step instruction on this site http://openhelp.net/?p=584. The only change with the steps stated on the site I've given is that I have used the latest mod_mono which is Mono 2.4.2.3. Below are the error message I am receiving when restarting apache using the command /sbin/service httpd restart :

[b][Mon Oct 12 10:46:33 2009] [crit] (2)No such file or directory: Failed to create shared memory segment for backend '/usr/local/bin/mod-mono-server2' at '/tmp/mod_mono_dashboard_/usr/local/bin/mod-mono-server2_2'.[/b]

Here is my mod_mono.conf:

LoadModule mono_module /usr/local/apache/modules/mod_mono.so


#MonoServerPath /usr/local/bin/mod-mono-server2 .verbose
MonoServerPath /usr/local/bin/mod-mono-server2 -verbose

And here is what I added on my httpd.conf:

LoadModule mono_module modules/mod_mono.so

I can run $ xsp command on the directory where I have my aspx pages. The page runs smoothly with xsp command but it stop the service as soon as I close my shell. My only problem is that, how can I keep it alive without the use of that command? Or is there a way to automatically start the xsp command on that directory when I restart my apache? Hoping for your response guys.

Thanks,
Alvin

Welcome to the CentOS fora. Please do the [url=http://www.centos.org/modules/newbb/viewforum.php?forum=47]required reading[/url] including [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=14408&forum=47]Installing Software[/url] and note the advice about [url=http://wiki.centos.org/PackageManagement/SourceInstalls]source installs[/url] - the procedure (unfortunately) recommended by the document you followed.

The above will lead you to the [url=http://wiki.centos.org/Repositories]repositories page[/url] that covers the CentOS extras repository among other repos. Note the warnings and advice about installing and configuring [url=http://wiki.centos.org/PackageManagement/Yum/Priorities]yum-priorities[/url]. Non-core repos should have a higher numeric value, which is a lower priority. Lower is "better" as in golf scores.

Mono is available from [extras] and there is a group definition, so after removing the broken source install (may be non-trivial) and configuring the repo[code]
yum groupinstall Mono
[/code]

Thanks for the response.

Does this means I have to uninstall what I have installed? and just use yum groupinstall Mono. Does this group install already have mod_mono? sorry I'm really new to this.

That's what I meant by "after removing the broken source install (may be non-trivial)". May be as easy as "make uninstall" and remove the old source directory. If you don't remove it then which version is found will depend on path ordering, and may lead to errors and confusion.

If not, then just follow by "yum install mod_mono".

Thanks for the reply pschaff.

I have tried the method that you suggested but it seems that the mod_mono was not installed properly.

Here is the step by step procedure I did:

1. I uninstalled mod_mono, mono and XSP using the [b]make uninstall [/b] command Afterwards, I deleted the directory using [b]rm -rf "directoryname"[/b].

After cleaning the previously installed application I make use of the command

2. [b]yum groupinstall Mono[/b]
3. [b]yum install mod_mono[/b]
4. [b]yum install xsp[/b]

Then after the installation, I used XSP command on the directory wherein I have my aspx pages but it seems that mod_mono is not installed. I hope you can guide me more on how will I be able to install mod_mono on my server without having the need of using XSP command and also removing the port 8080 on the url.

Your help will be highly appreciated. :-)

Thanks in advance.

I suspect there are still after-effects of your source install in /usr/local/... and the environment and other changes in the procedures you followed. Might want to evaluate the option of doing a fresh install and not corrupting it with source installs and associated configuration, versus spending a lot of time fixing the damage.
