Cacti基于Linux的流量监控

Cacti是一个大型网络中使用的很好的监控软件,它既能够在Linux上安装也能够在Windows上进行安装.今天主要讲解一下关于Linux的Cacti的安装过程以及它的相关使用操作:

1.安装apache

#tar xvzf xxxx

#./configure –prefix=/app/apache –enable-module=so && make && make install

#/app/apache/bin/apachectl start

2.安装mysql

#tar….

#./configure –prefix=/app/mysql && make && make install

#./scripts/mysql_install_db

ldconfig

./bin/mysqld_safe –user=root &

./bin/mysqladmin -u root -p password ‘xxxxxx’ #改root密码

./bin/mysql -p

mysql>use mysql;

mysql>show tables;

mysql>exit

#出来表就OK了

3.安装php.(这里面需要安装4.x版,不要5.x)

#tar…

#./configure –prefix=/app/php –with-mysql=/app/mysql –with-apxs2=/app/apache/bin/apxs

#make

#make install

#cp ./php.ini-dist /usr/local/lib/php.ini

#vi /app/apache/conf/httpd.conf #增加一行AddType application/x-httpd-php .php

#/app/apache/bin/apachectl restart

#可以编写一个PHP文件,测试PHP工作正常否.内容

4.安装phpMyadmin(可步可省)

#tar xvzf phpMy…

#mv phpM…. /app/apache/htdocs/phpMyadmin

#vi /app/apache/htdocs/phpMyadmin/config.inc.php

5.安装netsnmp(系统自带的即可,net-snmp-utils-xxx.i386.rpm),

安装rrdtool

tar…

./configure –prefix=/app/rrdtool && make && make install

6.安装cacti

tar…

/app/mysql/bin/mysqladmin –user=root -p create cacti #创建表

/app/mysql/bin/mysql –user=root -p cacti GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY ‘hhjzlp’;

mysql>flush privileges;

mysql>exit

vi ./include/config.php #改密码,其它看着改

adduser cactiuser

passwd cactiuser #设置密码hhjzlp

mv cacti.. /app/apache/htdocs/cacti

cd /app/apache/htdocs/cacti

chown -R cactiuser rra/ log/

然后通过http来安装.

把rrdtool路径改一下.按照上面设的,改成/app/rrdtool/bin/rrdtool

php路径:/app/php/bin/php

默认用户名密码都是admin,需要改密码(强制).

让系统每5分钟收集,需要

crontab -e

5/* * * * * /app/php/bin/php /app/apache/htdocs/cacti/poller.php > /dev/null 2>&1

也可手工跑一次: /app/php/bin/php /app/apache/htdocs/cacti/poller.php

(不要用root用户运行)

cacti配置比较简单.
