cacti 网络流量监测图形分析工具

 Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。

安装方法

一、安装rrdtool

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 2005 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-image: 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

 

  8、完成cacti的安装

 

  1) 在浏览器中输入:http://www.yourdomain. com/cacti/

 

  默认用户名:admin 密码:admin

 

  2) 更改密码

 

  3)设置cacti用到的命令路径
