Install Mono on CentOS

In addition to Mono website, Mono is available also at http://ftp.novell.com/pub/mono/download-stable/RHEL_5/x86_64/.

First, create a repository description in /etc/yum.repos.d. Create file mono.repo with content

[Mono]
name=Mono Stack (RHEL_5)
type=rpm-md
baseurl=http://ftp.novell.com/pub/mono/download-stable/RHEL_5/
gpgcheck=1
gpgkey=http://ftp.novell.com/pub/mono/download-stable/RHEL_5/repodata/repomd.xml.key
enabled=1

Second, install the Mono “server” stack:
        yum clean all
        yum install monotools-addon-server

Wait for all packages installed. The binary file will be installed at /opt/novell/mono/bin.

To setup the running environment, run
        source /opt/novel/mono/bin/mono-addon-environment.sh

To verify everything is installed:
        mono --version
