RPM包安装方法
文档
http://sourceforge.net/apps/trac/ganglia/wiki/ganglia-web-2#Installation
下载安装包 制作rpm包
cp ../ganglia-3.1.7.tar.gz /usr/src/redhat/SOURCES/
rpmbuild -bb ganglia.spec
cd /usr/src/redhat/RPMS/x86_64
拷贝对应安装包安装，配置同上
rpm -ivh ganglia-3.0.7-1.el5.x86_64.rpm rpm -ivh ganglia-gmond-3.0.7-1.el5.x86_64.rpm
