安装如下：

英文地址：http://www.cyberciti.biz/faq/fedora-rhel-install-cacti-monitoring-rrd-software/

1:安装关联软件

yum install mysql-server mysql php-mysql php-pear php-common php-gd php-devel php php-mbstring php-cli php-snmp php-pear-Net-SMTP php-mysql httpd

yum源更换：http://www.cnblogs.com/tommyli/p/3179753.html

yum源的epel：https://fedoraproject.org/wiki/EPEL/zh-cn

yum命令：http://www.cyberciti.biz/faq/rhel-centos-fedora-linux-yum-command-howto/

2：配置mysql

mysqladmin -u root password NEWPASSWORD

如何更改mysql的root密码：http://www.cyberciti.biz/faq/mysql-change-root-password/

3：创建cacti数据库

mysql -u root -p -e 'create database cacti'

创建账户{u:cacti p:zYn95ph43zYtq}

mysql -u root -p
GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY 'zYn95ph43zYtq';
FLUSH privileges;
\q

4：安装snmpd

yum install net-snmp-utils php-snmp net-snmp-libs

修改snmpd的配置

vi /etc/snmp/snmpd.conf

添加如下选项

com2sec local     localhost           public
group MyRWGroup v1         local
group MyRWGroup v2c        local
group MyRWGroup usm        local
view all    included  .1                               80
access MyRWGroup ""      any       noauth    exact  all    all    none
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root  (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat

开启snmpd服务

/etc/init.d/snmpd start
chkconfig snmpd on

确认下服务运行

snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex

可能的输出

IP-MIB::ipAdEntIfIndex.10.10.29.68 = INTEGER: 2
IP-MIB::ipAdEntIfIndex.67.yy.zz.eee = INTEGER: 3
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1

5：安装cactl{yum要epel支持，见小节1，否则找不到这个安装包}

yum install cacti

初始化cactl数据库

rpm -ql cacti | grep cacti.sql

可能的输出

/usr/share/doc/cacti-0.8.7d/cacti.sql

初始化（版本可能和我的不一样）

mysql -u cacti -p cacti < /usr/share/doc/cacti-0.8.7d/cacti.sql

修改cacti数据库配置

vi /etc/cacti/db.php

替换

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "zYn95ph43zYtq";
$database_port = "3306";

修改httpd的配置

vi /etc/httpd/conf.d/cacti.conf

替换

Alias /cacti    /usr/share/cacti
 
<Directory /usr/share/cacti/>
        Order Deny,Allow
        Deny from all
        Allow from 10.0.0.0/8
</Directory>

启动httpd服务

service httpd restart

创建cacti cronjob

vi /etc/cron.d/cacti

去掉第一行的注释

*/5 * * * *     cacti   /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

浏览cacti

http://your.server.ip.address/cacti/

第一次强制修改密码的，初始账号和密码都是admin

6：如何创建snmp数据采集源

1：点击Devices
2：选择Localhost
3：选定SNMP（下面可选snmp的版本）
4：save

7：如何创建snmp图

1：Click on "Create Graphs for this Host" link on top right side.
2：Select SNMP - Interface Statistics
3：Select a graph type (such as In/Out bytes with total bandwidth)
4：Finally, click on Create button.
