Install cacti in yum under CentOS 6

Brief description: It was originally compiled and installed. Because there are too many library files associated during the compilation process, the installation files must be sequential and there are too many errors. When rrdtool is started, it says that everything cannot be installed, due to time issues, I chose yum for installation. for compilation and installation, this is much simpler. She automatically installed all the associated files, saving a lot of trouble, the following describes how to install yum:
First, deploy the yum environment. There are many yum sources in China, such as sohu, 163, and HKUST. The configuration is very simple. You can check the configuration on the Internet.
Deployment environment: (LAMP + RRDTool + snmp + cacti)

1. Configure the LAMP Environment
