I would like to share my experience of making a virtual Linux server to serve ASP.NET websites. The procedures aren’t new, but it was somewhat tricky to use multiple information sources and my own experience to achieve this goal. Anyway, this article will serve as a little how-to for myself and hopefully you will find it useful too.
System that has been used: VirtualBox, CentOS 6.5 (x86_64), Apache 2.2, Mono 3.4.0 and ISPConfig 3.0.5.4

Installing the hosting system (optional)
The Perfect Server – CentOS 6.4 x86_64 (Apache2, Dovecot, ISPConfig 3) OR Installing and configuring CentOS 6.3 XFCE mini server

Setting up installation environment
Install all dependencies:
yum install bison gettext glib2 freetype fontconfig libpng libpng-devel libX11 libX11-devel glib2-devel libgdi* libexif glibc-devel urw-fonts java unzip gcc gcc-c++ automake autoconf libtool make bzip2 wget libungif-devel freetype-devel libtiff-devel libjpeg-devel xulrunner-devel perl-TimeDate.noarch expect
Go to root’s directory, make mono folder there, and jump into it:
cd /root
mkdir mono
cd mono

Installation
Installing mod_mono
cd ~/mono/mod_mono-2.10
./configure --prefix=/usr
Output:
Configuration summary for mod_mono * Installation prefix = /usr * Apache version = 2.2 * Apache modules directory = /usr/lib64/httpd/modules * apxs = /usr/sbin/apxs * apr-config = /usr/bin/apr-1-config * apu-config = /usr/bin/apu-1-config * CFLAGS = -g -O2 -I/usr/include/httpd -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -Wformat-security -fno-strict-aliasing -pthread -I/usr/include/apr-1 -pthread -I/usr/include/apr-1 * Verbose logging (debug) = no * GCOV options used = no * Profiling enabled = no * mono prefix = /usr/lib/pkgconfig/../.. * Default MonoApplicationsConfigDir = /etc/httpd/conf/mod-mono-applications
make
make install
ldconfig
Installing libgdiplus
cd ~/mono/libgdiplus-2.10.9
./configure --prefix=/usr
Output:
Configuration summary * Installation prefix = /usr * Cairo = 1.8.8 (system) * Text = cairo * EXIF tags = No. Get it from http://libexif.sourceforge.net/ * Codecs supported: - TIFF: yes - JPEG: yes - GIF: yes - PNG: yes NOTE: if any of the above say 'no' you may install the corresponding development packages for them, rerun autogen.sh to include them in the build.
make
make install
Back to Top
Installing mono
Switch to extracted mono folder:
cd ~/mono/mono-3.4.0
Run following commands to configure and install mono:
./autogen.sh --prefix=/usr
OR ./configure --prefix=/usr
The output you should see:
mcs source: mcs Engine: GC: sgen and bundled Boehm GC with typed GC and parallel mark TLS: __thread SIGALTSTACK: yes Engine: Building and using the JIT oprofile: no BigArrays: no DTrace: no LLVM Back End: no (dynamically loaded: no) Libraries: .NET 2.0/3.5: yes .NET 4.0: yes .NET 4.5: yes MonoDroid: no MonoTouch: no JNI support: IKVM Native libgdiplus: assumed to be installed zlib: system zlib
Continue with setup:
perl -pi -e 's/HAVE_LOCALCHARSET_H 1/HAVE_LOCALCHARSET_H 0/' eglib/config.h
Get the latest version of the monolite distribution, which contains just enough to run the mcs compiler:
make get-monolite-latest
OR make monolite_url=http://storage.bos.xamarin.com/mono-dist-master/bf/bf17a43b31a2be16f462ffdf1ae3d9801b846e90/monolite-110-latest.tar.gz get-monolite-latest
OR make monolite_url=http://storage.bos.xamarin.com/mono-dist-master/latest/monolite-111-latest.tar.gz get-monolite-latest
if previous command doesn’t work.
You may want to run the mono and mcs tests. All tests should pass.
make check
And finally installation:
make -j 8
(may take a while)
make install
Check if you got mono installed successfully:
mono -V
The output:
Mono JIT compiler version 3.4.0 (tarball Thu Apr 24 03:05:33 GMT 2014) Copyright (C) 2002-2012 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com TLS: __thread SIGSEGV: altstack Notifications: epoll Architecture: amd64 Disabled: none Misc: softdebug LLVM: supported, not enabled.

Add the path to your ~/.bash_profile
echo export PKG_CONFIG_PATH=/usr/lib/pkgconfig:$PKG_CONFIG_PATH>>~/.bash_profile
echo export PATH=/usr/bin:$PATH>>~/.bash_profile
source ~/.bash_profile
Should you wish to access mod_mono control panel, add these lines to /etc/httpd/conf/httpd.conf:
<Location /mono> SetHandler mono-ctrl Order deny,allow Deny from all Allow from 192.168.0.2 </Location>
Replace 192.168.0.2 (or add more Allow lines) with the IP address of your own computer so that you can access the control panel.
Restart Apache and now you will be able to access mono control panel via http://yourdomainoripaddress/mono/.
service httpd restart
Back to Top
Installing XSP
Go to xsp folder, configure and install it:
cd ~/mono/xsp-2.10.2
./configure --prefix=/usr
Output:
xsp-2.10.2 Build Environment Install prefix: /usr Datadir: /usr/share Libdir: /usr/lib Build documentation: yes Mono 2.0 compiler: /usr/bin/gmcs Mono 4.0 compiler: /usr/bin/dmcs Target frameworks: .NET 2.0, .NET 4.0 Build SQLite samples: yes
export PKG_CONFIG_PATH=`whereis pkgconfig | awk '{print $2}'`
make
make install
Back to Top
Configuring ISPConfig 3 (optional)
Add line Include /etc/httpd/conf/mod_mono.conf to /etc/httpd/conf/httpd.conf:
vi /etc/httpd/conf/httpd.conf
Here is how it should look like:
[..] Include /etc/httpd/conf/mod_mono.conf # ISPConfig stuff NameVirtualHost *:80 NameVirtualHost *:443 Include /etc/httpd/conf/sites-enabled/
Restart Apache:
service httpd restart
Now in your ISPConfig control panel pick a website that you want to run as ASP.NET and change its settings similar to these (no changes needed in Options tab):
Once you’ve done this, you will have to change the ownership of website’s root directory and subdirectories to apache user/group or otherwise you will get this error “System.UnauthorizedAccessException: Access to the path “/var/www/www.yourdomain.com/web” is denied.“. Please let me know if you found a workaround for this issue.
chown -R apache:apache /var/www/clients/client1/web1/web
Restart Apache:
service httpd restart
Back to Top
Testing
In order to test if Apache serves ASP.NET files, add default.aspx file to your websites root directory with following lines:
Unfortunately, you will have to change the permissions of newly added files every time you upload them…
chown -R apache:apache /var/www/clients/client1/web1/web
Now go to your browser and type the address of your website to see the lovely “Hello, World!” 🙂
If all went fine, that’s all you should see in your /var/log/httpd/error.log:
[Thu Apr 24 04:52:00 2014] [notice] caught SIGTERM, shutting down mod-mono-server received a shutdown message [Thu Apr 24 04:52:03 2014] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) [Thu Apr 24 04:52:03 2014] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?)

Hello Eliot,
Please make sure you’ve typed the path to your configuration files right, as in your error message I can see a space in it.
Hope this helps.

I had problem compiling mono, particularly mod_mono.c. It seems that the following structure have been renamed as per Apache API change log.
unixd_config => ap_unixd_config

Hello,
I have followed this guide, but mod_mono is looking for mono at /usr/local/bin/mono (at runtime). However, /usr/local/bin/mono does not exist. The correct bin directory appears to be: /usr/local/mono/bin.
How can I fix this?
Fred Rester –
May 5, 2014 at 21:44 - 10 years ago
OOPS!
I meant to write: “The correct bin directory appears to be: /usr/bin/mono.”
Does it matter that I installed everything as the root user?
Fred Rester –
May 5, 2014 at 23:20 - 10 years ago
GAH!
It looks like someone else in this comment thread had the same problem, so I tried his fix:
ln -s /usr/bin/mono usr/local/bin/mono
However, now I get this!
Now I just feel bad inside. 🙁
Fred Rester –
May 6, 2014 at 10:30 - 10 years ago
Fixed! I deleted everything “mono” i could find via “find” command. then, I started from step 1. Everything works now. (My issue had to do with old mono installations, and possibly a lack of installing XSP.)
Thank you for making the only CentOS 6 mod-mono tutorial that seems to work!

Hello buddy,
I also run into similar sort of problems last time I’ve tried to setup Mono on a little bit different server configuration, but they happened due to the download error of the latest monolite. I’ll try to repeat the setup again and see what happens.
However, XSP and mod_mono installations worked fine with Mono version 3.2.6.

Hi Donatas,
Thanks for your quick reply. Dont waste your time to reproduce the above error… 🙂
I am able to resolve the above error by linking with below command
ln -s /usr/bin/mono /usr/local/bin/mono
But again I stuck in another error:
Searching a lot I found similar error post but no satisfied solution to overcome with this.
Any luck…!!!
Thanks in advance.

Hello, buddy!
I just optimized the tutorial for version 3.4.0 and everything is working fine now.
