一、 更新系统
yum –y update
二、安装Mono源码安装需要的库
yum -y install gcc gcc-c++ bison pkgconfig glib2-devel gettext make libpng-devel libjpeg-devel libtiff-devel libexif-devel giflib-devel libX11-devel freetype-devel fontconfig-devel cairo-devel bzip2
三、安装Mono需要的GDI+兼容API的库Libgdiplus
cd /usr/local/src/
wget http://120.52.73.80/download.mono-project.com/sources/libgdiplus/libgdiplus-4.2.tar.gz
tar -zxvf libgdiplus-4.2.tar.gz
cd libgdiplus-4.2
./configure --prefix=/usr
make
make install
四、安装 mono
cd /usr/local/src/
wget http://download.mono-project.com/sources/mono/mono-4.4.2.4.tar.bz2
tar -jxvf mono-4.4.2.4.tar.bz2
cd mono-4.4.2
