1 cacti運行環境准備
cacti需要php+apache+mysql+snmp+RRDTool，以及cacti本身。cacti本體是用php開發的網站，通過snmp對遠端設備信息進行采集。apache+mysql+php在以前已經做過了，鏈接如下：

這里只對剩余的部分進行安裝。
2 安裝snmp
yum install -y net-snmp*
vi /etc/snmp/snmpd.conf
com2sec notConfigUser default public //將default修改為127.0.0.1
access notConfigGroup"" any noauth exact systemview none none //將systemview改為all
#view all included .1 //去掉#注釋
systemctl start snmpd
systemctl enable snmpd
3 安裝RRDTool
yum install libart_lgpl libart_lgpl-devel
yum install rrdtool.x86_64 rrdtool-devel.x86_64
4 安裝相關lib
yum install gcc glibcglibc-common cairo pango zlib zlib-devel freetype freetype-devel gd gd-devel
5 mysql配置
mysql -uroot -p //登錄mysql
create database cacti CHARSET 'utf8'; //創建cacti用的庫
GRANT ALL ON cacti.* TO cactiuser@'127.0.0.1' IDENTIFIED BY 'cactipass'; //創建cactiuser並賦權
6 下載並安裝cacti
在cacti官網下載cacti-0.8.8f.tar.gz
復制到apache的www目錄並解壓該包
cd /var/www/html/
tar xvf cacti-0.8.8f.tar.gz
mv cacti-0.8.8f cacti //目錄重命名
cd /var/www/html/cacti
mysql cacti <cacti.sql //初始化cacti數據庫
useradd cactiuser //創建cacti user
chown -R cactiuser:cactiuser /var/www/html/log /var/www/html/rra //修改目錄的訪問權限
vim /etc/php.ini
date.timezone =Asia/Shanghai //修改php時區
systemctl restart httpd //重啟apache
7 瀏覽器中輸入
http://ip/cacti 開始cacti的安裝配置
按提示進行配置或包安裝
