　　版本是cacti-0.8.7g、cacti-plugin-0.8.7g-PA-v2.8、rrdtool-1.4.4、net-snmp-5.6
　　一、软件列表及作用
1、安装rrdtool（cacti用来保存数据及绘图形的工具）
2、安装net-snmp（使用snmpget获取数据）
3、安装cacti（php程序，管理界面）
4、安装spine（基于C快速的轮询引擎，用它替代cmd.php作数据采集）
5、安装插件（扩展监控数据等，cacti-plugin扩展cacti架构而支持插件，monitor图形方式显示设备状态，thold设备异常报警，settings邮件报警）
註：apache、mysql、php环境需先安装好，此处忽略。
　　二、安装

make
make install
/usr/local/rrdtool/bin/rrdtool #测试
　　2、安装net-snmp
wget http://nchc.dl.sourceforge.net/project/net-snmp/net-snmp/5.6/net-snmp-5.6.tar.gz
tar -zxvf net-snmp-5.6.tar.gz
cd net-snmp-5.6
./configure --prefix=/usr/local/net-snmp  --enable-developer --with-default-snmp-version="2" --with-sys-contact="admin@admin.com" --with-sys-location="China" --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp"

make
make install
cd /usr/local/spine/etc/
cp spine.conf.dist spine.conf
配置数据库用户名及密码
vi spine.conf
/usr/local/spine/bin/spine #测试spine
　　5、安装插件

/usr/local/mysql/bin/mysql -u root -p
mysql>use cacti;
mysql>set NAMES utf8;
mysql>source /home/htdocs/cacti/cacti-plugin-arch/pa.sql;
　　页面无css而变形，改为cacti对应于web目录下的路径
