2.安装rrdtool
Rrdtool安装需要cairo、libxml2、pango库支持，可通过yum安装
# yum -y install cairo-devel libxml2-devel pango-devel
# tar zxvf rrdtool-1.4.7.tar.tar
# cd rrdtool-1.4.7
# ./configure --prefix=/usr/local/rrdtool
# make && make install
# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/
3.安装net-snmp
# tar zxvf net-snmp-5.6.1.1.tar.gz
# cd net-snmp-5.6.1.1
# ./configure --prefix=/usr/local/net-snmp
# make && make install
# cp EXAMPLE.conf /etc/snmpd.conf
# ln -s /usr/local/net-snmp/bin/* /usr/local/bin/
# vim /etc/snmpd.conf
rocommunity public localhost #去掉注释
# /usr/local/net-snmp/sbin/snmpd -c /etc/snmpd.conf
加入开机启动
# echo "/usr/local/net-snmp/sbin/snmpd -c /etc/snmpd.conf " >>/etc/rc.local
4.安装cacti
# tar zxvf cacti-0.8.7i-PIA-3.1.tar.gz
# mv cacti-0.8.7i-PIA-3.1/* /var/www/html/
#将cacti中的内容移到 web目录
# chown -R apache:apache /var/www/html/
# mysql -uroot
#连接到mysql创建数据库
mysql> create database cacti;
#创建cacti数据库
mysql> insert into mysql.user(host,user,password) values ('localhost','cacti',password('cacti123'));
#建立用户cacti，密码cacti123
mysql> flush privileges;
#重载mysql授权表
mysql> grant all on cacti.* to cacti@'localhost' identified by 'cacti123';
#把数据库cacti授权于用户cacti
# cd /var/www/html/
# mysql -ucacti -pcacti123 cacti<cacti.sql #将cacti数据库导入
修改网站配置文件，使用正确连接数据库参数
# vim include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti123";
$database_port = "3306";
使用浏览器打开http://192.168.209.130/install/
会看到安装向导，点下两个NEXT之后，出现以下：

http://ysp68d76dbea889a1a0.yunshipei.cn/dHlwZT1mdyZzaXplPTY0MCZzcmM9YUhSMGNDVXpRU1V5UmlVeVJtbHRaekV1TlRGamRHOHVZMjl0SlRKR1lYUjBZV05vYldWdWRDVXlSakl3TVRJd05DVXlSakk0SlRKR05EUXlPVE16WHpFek16VTJNVGt3TURVelZqbDBMbXB3Wnc9PQ==
默认用户名和密码admin,第一次登录会要求更改密码
5.设置cacti数据采集轮询时间
# crontab –e
*/5 * * * * env LANG=C /usr/bin/php /var/www/html/poller.php
三、常用插件安装
最新版本cacti-0.8.7i-PIA-3.1 集成了plugin架构扩展，所以可以直接开启后就可以安装其他插件

Cacti轮询时间
Cacti默认的轮询时间为5分钟，可通过安装spine将时间变成一分钟
下载：http://cacti.net/spine_download.php
1.安装spine
# tar zxvf cacti-spine-0.8.7i.tar.gz
# cd cacti-spine-0.8.7i
# ./configure --prefix=/usr/local/cacti-spine --with-snmp=/usr/local/net-snmp/
# make && make install
# cd /usr/local/cacti-spine/etc/
# cp spine.conf.dist spine.conf
# vim spine.conf
DB_Host localhost
DB_Database cacti
DB_User cacti
DB_Pass cacti123
DB_Port 3306
DB_PreG 0
这里修改对应的mysql用户名和密码，以及连接参数
打开“console”----“settings”----“Paths” 中填写spine的路径,然后“save”
http://ysp68d76dbea889a1a0.yunshipei.cn/dHlwZT1mdyZzaXplPTY0MCZzcmM9YUhSMGNDVXpRU1V5UmlVeVJtbHRaekV1TlRGamRHOHVZMjl0SlRKR1lYUjBZV05vYldWdWRDVXlSakl3TVRJd05DVXlSakk0SlRKR05EUXlPVE16WHpFek16VTJNVGt3TVROM2VuaG9MbXB3Wnc9PQ==
2.选择轮询模式
打开“console”----“settings”----“Poller”---“save”
http://ysp68d76dbea889a1a0.yunshipei.cn/dHlwZT1mdyZzaXplPTY0MCZzcmM9YUhSMGNDVXpRU1V5UmlVeVJtbHRaekV1TlRGamRHOHVZMjl0SlRKR1lYUjBZV05vYldWdWRDVXlSakl3TVRJd05DVXlSakk0SlRKR05EUXlPVE16WHpFek16VTJNVGt3TVRkWlRuTTRMbXB3Wnc9PQ==
添加“每分钟”流量视图
打开“console”---“Data Templates”——“Interface - Traffic”
http://ysp68d76dbea889a1a0.yunshipei.cn/dHlwZT1mdyZzaXplPTY0MCZzcmM9YUhSMGNDVXpRU1V5UmlVeVJtbHRaekV1TlRGamRHOHVZMjl0SlRKR1lYUjBZV05vYldWdWRDVXlSakl3TVRJd05DVXlSakk0SlRKR05EUXlPVE16WHpFek16VTJNVGt3TVRoaWVrdzBMbXB3Wnc9PQ==
http://ysp68d76dbea889a1a0.yunshipei.cn/dHlwZT1mdyZzaXplPTY0MCZzcmM9YUhSMGNDVXpRU1V5UmlVeVJtbHRaekV1TlRGamRHOHVZMjl0SlRKR1lYUjBZV05vYldWdWRDVXlSakl3TVRJd05DVXlSakk0SlRKR05EUXlPVE16WHpFek16VTJNVGt3TWpCNWRVMTZMbXB3Wnc9PQ==
其他模板做相应修改。
最后修改crontab中的
* * * * * env LANG=C /usr/bin/php /var/www/html/poller.php>/dev/null 2>&1 。。。。。 不错！ 学习了，可以实践一下 为何图片显示不出来，LZ图片上传方式不对。配置学习一下
