环境：windows7 VMware Esxi4+CentOS6.1
第一步：安装配置Cacti环境
#yum install mysql mysql-server httd php php-mysql -y
mysql-server //安装mysql服务
httd //安装apache
php //安装PHP
php-mysql //安装PHP与mysql的……

====================================================
第二步：安装Cacti所需的各种库
#yum install zlib libpng freetype jpeg fontconfig gd libxml -y //zlib一般默认
己安装
====================================================I
nstalled:
freetype.i686 0:2.3.11-6.el6_1.8
gd.i686 0:2.0.35-10.el6 libpng-1.2.46-1.el6_1.i686

libjpeg.i686 0:6b-46.el6 libxcb.i686 0:1.5-1.el6
====================================================
第三步：安装绘图所要用到的rrdtool
#yum install rrdtool -y
现在6.2版本源增加了不少，安装很多软件真是方便呀，以前在5.0的时候用yum无法安装rrdtool只
能用wget
====================================================
Installed:
rrdtool.i686 0:1.3.8-6.el6
Dependency Installed:
cairo.i686 0:1.8.8-3.1.el6 dejavu-fonts-common.noarch
0:2.30-2.el6 dejavu-lgc-sans-mono-fonts.noarch 0:2.30-2.el6

pixman.i686 0:0.18.4-1.el6_0.1
====================================================
===========================================
第四步：安装snmp支持
#yum install net-snmp net-snmp-utils -y
====================================================
Installed:
net-snmp.i686 1:5.5-37.el6_2.1
net-snmp-utils.i686 1:5.5-37.el6_2.1
Dependency Installed:
lm_sensors-libs.i686 0:3.1.1-10.el6
net-snmp-libs.i686 1:5.5-37.el6_2.1
====================================================
第五步：安装Cacti
这一点不爽，为什么还不支持yum来安装cacti，debian和ubuntu都支持apt-get来直接安装
====================================================
#wget -c
--2012-01-31 19:59:36--
Resolving 209.242.232.5, 140.211.167.231, 173.225.179.10

====================================================
tar -xvzf cacti-0.8.7g.tar.gz
mv cacti-0.8.7g cacti //这步可以不做，我只是为了给这个长
文件名改短一点，没有任何意思
cp -a cacti/. /var/www/html/ //同样这步做不做都行，我是为了省事把cacti
目录下的全部文件及子目录拷贝到httpd默认的目录下，懒的改httpd
第六步：为cacti建立用户和库
# service mysqld start
首先为mysql的root设置密码，在安装好mysql后一般默认是没有密码的，这样不安全
#/usr/bin/mysqladmin -u root password 123456
然后登录到mysql
#mysql -uroot -p 123456
mysql>show databases; //查看数据库
mysql>create database cacti; //建立cacti数据库
Query OK, 1 row affected (0.00 sec)
mysql>show databases; //再次查看
第七步：建立用户并授权用户Cacti数据库的全部权限及网络访问权限
GRANT ALL PRIVILEGES ON cacti.* TO cactiuser@localhost IDENTIFIED BY
"11223344";
Query OK, 0 rows affected (0.00 sec)
授权用户网络访问的权限：
GRANT ALL PRIVILEGES ON cacti.* TO cactiuser@"%" IDENTIFIED BY "123456";
Query OK, 0 rows affected (0.00 sec)
GRANT ALL PRIVILEGES ON cacti.* TO cactiuser@[ip address或者“%”] IDENTIFIED
BY "11223344";
ip address是指定ip，如果想在任何地点使用的话可以用通配符"%"注意输入时不要忘记
冒号
# /usr/bin/mysqladmin --user=root create cacti
# mysql -e "GRANT ALL ON cacti.* TO cactidate IDENTIFIED BY 'admin'"
第七步：导入cacti库
mysql -ucactiuser -p11223344 cacti < /var/www/html/cacti.sql
第八步：编辑config.php
vim /var/www/html/include/config.php
====================================================
原内容：
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";
$database_port = "3306";
改为：
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "11223344";
$database_port = "3306";
====================================================
第九步：启动httpd
#/etc/init.d/httpd start
第十步：验证php
建立一个php测试页
vim php.php
phpinfo();
?>
第十一步：配置iptables
如查在安装CentOS时没有特别定制的话，默认是只有TCP22端口是开放的，所以要配置一
下
vim /etc/sysconfig/iptables
====================================================
原有内容：
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
增加几条
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
//http所要用到的端口
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
//mysql所要用到的端口
-A INPUT -p udp -m udp --dport 161 -j ACCEPT
//snmp所要用到的端口
====================================================
配置完成后重启iptables让配置生效
/etc/init.d/iptables restart
第十二步：Cacti的web页面安装
打开浏览器输入： address/
