tar xf cacti-0.8.7g.tar.gz
mv cacti-0.8.7g /data/www/cacti
cd /data/www/cacti
导入cacti数据库
# mysql -ucacti -pcacti888 cacti<cacti.sql
修改配置文件
# vim include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti888";
修改apache配置文件开启虚拟机
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName www.cacti.com
DocumentRoot "/data/www/
DirectoryIndex index.php
<Directory "/data/www">
Options -Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
启动httpd 测试cacti
修改snmpd.conf
# vim snmpd.conf
com2sec notConfigUser 192.168.0.171 nick
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup "" any noauth exact all none none
view all included .1 80
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
重启snmpd服务
# /etc/init.d/snmpd restart
手动执行查询数据，是不是有数据显示
/usr/bin/php /data/www/cacti/poller.php
查看 /data/www/cacti/rra 是不是有数据文件
增加入一个计划任务，使得 cacti 每分钟生成一个监控图表。

添加插件 cacti-plugin 扩展cacti架构
tar xf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
cd cacti-plugin-arch/
cp cacti-plugin-0.8.7g-PA-v2.8.diff /data/www/cacti/
cp pa.sql /data/www/cacti/
cd /data/www/cacti/
打补丁
patch -p1 <cacti-plugin-0.8.7g-PA-v2.8.diff
导入数据
mysql -ucacti -pcacti888 cacti <pa.sql
修改配置文件
vim include/global.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti888";
测试游览器，如果打不开网页修改 include/config.php
$url_path="/"; 修改为 $usl_path="/cact/";
