CentOS-5: rpm -ivh http://apt.sw. be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.i386.rpm yum install rrdtool -y CentOS-6: rpm -ivh http://apt.sw. be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.i686.rpm yum install rrdtool -y二、安装配置net-snmp
1、安装net-snmp
yum install net-snmp net-snmp-libs net-snmp-utils
2、配置net-snmp
修改：
view systemview included .1.3.6.1.2.1.1
为：
view systemview included .1.3.6.1.2.1
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 i686
三、安装LAMP
yum install 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
四、安装cacti
1、下载cacti
cd /tmp
wget http://www.<cite class="highlight" highlight="true" style="background-p_w_picpath: none; background-position: initial initial; background-repeat: initial initial; ">cacti. net</cite>/downloads/cacti-0.8.8a.tar.gz
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@localhost IDENTIFIED 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 Cacti install
ex: if your cacti install as at http://serverip/cacti/ this
would be set to /cacti/
*/
$url_path = "/cacti/";
/* Default session name - Session name must contain alpha characters */
#$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。
7、配置计划任务
echo "*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1">>/etc/crontab
service crond restart
