1、查看mono最新版本
http://download.mono-project.com/sources/mono
2、安装依赖环境
sudo yum install cmake automake libtool libgdiplus libpango1.-dev libatk1.-dev libgtk2.-dev libglade2-dev gcc gcc-c++ gcc autoconf -y
3、下载安装
wget http://download.mono-project.com/sources/mono/mono-4.8.0.382.tar.bz2 tar -xvf mono-4.8.0.382.tar.bz2 cd mono-4.8.0.382 ./configure --prefix=/usr/local make make install
