Centos5 Upgrade Mono

I Use Centos5 as my Linux system operation. Default mono-core installed in centos is mono-core-1.2.4-2.el5.centos. This version is to old and I want to install or upgrade mono. This is a method how to install or upgrade mono in Centos5.

• Create a new repo config file. vim /etc/yum.repos.d/mono.repo and add the following text :

[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

• Save this file and update repo list with command : yum clean all
• install the mono server stack with command : yum install monotools-addon-server
• set up shell environtment so that it finds mono, mcs and the other mono tools. Use this command : cp /opt/novell/mono/bin/mono-addon-environtment.sh /etc/profile.d
• edit file /etc/profile.d/mono-addon-environtment.sh and change this line PS1=”[mono-addon] $PS1″ with #PS1=”[mono-addon] $PS1″
• Log off your computer and after login again, check mono version with this command : mono –version. This is output from my computer :

[toto@localhost ]$ mono --version
