3、测试net-snmp
# service snmpd start
# snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux cronos 2.4.28#2 SMP ven jan 14 14:12:01 CET 2005 i686
三、安装LAMP
yuminstall httpd php php-mysql php-snmp php-xml php-gd mysql mysql-server
service httpd start
service mysqld start
mysqladmin -uroot password yourpassword
mysqladmin --user=root --password reload

tar xzf cacti-0.8.8a.tar.gz
mv cacti-0.8.8a /var/www/html/cacti
cd /var/www/html/cacti
2、创建数据库
mysqladmin --user=root -p create cacti
3、导入数据库
mysql -uroot -p cacti < cacti.sql
4、创建数据库用户
shell> mysql -uroot -p mysql
mysql> GRANT ALL ON cacti.* TO cactiuser@localhostIDENTIFIED BY 'cactipassword';
mysql> flush privileges;
5、配置include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactipassword";
/* load up old style plugins here */
$plugins = array();
//$plugins[] = 'thold';
/*
Edit this to point to the default URL of your Cactiinstall
ex: if your cacti install as at http://serverip/cacti/this
would be set to /cacti/
*/
$url_path = "/cacti/";
/* Default session name - Session name must containalpha characters */
#$cacti_session_name = "Cacti";
6、设置目录权限
chown -R cactiuser rra/ log/
cactiuser为系统存在的用户，为了收集数据。
