安装Cacti
1、首先要安装Apache+PHP+MySQL+Net-SNMP+RRDTool(MySQL安装、Apache安装、PHP安装)，本文采用YUM命令安装所有cacti依赖软件。过程如下：
-
yum install -y mysql mysql-server mysql-devel php-mysql httpd php php-pdo lm_sensors net-snmp net-snmp-devel openssl-devel php-snmp net-snmp-utils perl-Net-Daemon perl-PlRPC perl-DBI rrdtool perl-rrdtool perl-DBD-MySQL net-snmp-libs libtool ntpdate wget vixie-cron man lrzsz make
//配置SNMP
-
vi /etc/snmp/snmpd.conf
-----------------------------------------------------------------------
com2sec notConfigUser default public #将这行中的“default“改为127.0.0.1
com2sec notConfigUser 127.0.0.1 public
.....
access notConfigGroup "" any noauth exact systemview none none #将这行中的"systemview "改为all
access notConfigGroup "" any noauth exact all none none
.....
#view all included .1 80 将这行的注释"#"号去掉
view all included .1 80
-----------------------------------------------------------------------
//自动同步时间
-
ntpdate us.pool.ntp.org
//修改PHP时区
-
vi /etc/php.ini
-----------------------------------------------------------------------
#date.timezone = #去掉前面的注释并 改为 date.timezone = Asia/Shanghai
date.timezone = Asia/Shanghai
-----------------------------------------------------------------------
//启动snmpd/httpd/mysql服务
-
service snmpd start
-
chkconfig snmpd on
-
service httpd start
-
chkconfig httpd on
-
service mysqld start
-
chkconfig mysqld on
//安装cacti
-
wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz
-
tar zvxf cacti-0.8.8a.tar.gz
-
mv cacti-0.8.8a /var/www/html/cacti
//安装Spine插件
-
wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8a.tar.gz
-
tar -zxvf cacti-spine-0.8.8a.tar.gz
-
cd cacti-spine-0.8.8a
-
./configure --prefix=/var/www/html/cacti/app/spined
-
make
-
make install
//配置Spinecd

-----------------------------------------------------------------------
//添加cacti用户，否则cacti不能写入rrd和log目录，将会无法生成图片
#添加cacti用户
-
useradd cacti
-

-

#将log目录的所有权给cacti用户
-

#将rra目录的所有权给cacti用户
-
chown –R cacti /var/www/html/cacti/rra
//增加入一个计划任务，使得 cacti 每两分钟生成一个监控图表。注意poller.php路径
//安装crontab
# su cacti
# crontab –e

//完成cacti最后的配置，在浏览器输入：http://localhost/cacti
