nullnullHow to Install Cacti on Ubuntu

在写这篇文章之前，xxx已经写过了几篇关于改nullnull主题的文章,想要了解的朋友可以去翻一下之前的文章

    

    Installation prerequisite

    

    The following packages are required to run Cacti properly

    Apache2

# apt-get install apache2
# apt-get install php5 php5-cli php5-mysql php5-snmp

    MYSQL

# apt-get install mysql-server mysql-client

    SNMP

# apt-get install snmp snmpd

    RRDTool

    

# apt-get install rrdtool

    Cacti User

# useradd -d /home/cactiuser -m cactiuser

    Installation

    Download and decompress Cacti Package

# cd /usr/share
# wget http://www.cacti.net/downloads/cacti-0.8.7i.tar.gz
# gzip -d cacti-0.8.7i.tar.gz
# tar -xvf cacti-0.8.7i.tar
# mv cacti-0.8.7i cacti

    Create cacti DB

#mysql -p
mysql> create database cacti

    Import the default DB

mysql --user=root --password cacti < /usr/share/cacti/cacti.sql

    Create Cacti user and set the right privileges to the database

# mysql --user=root --password
 
mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipwd';
mysql> flush privileges;
mysql> exit

    每日一道理
试试看——不是像企鹅那样静静的站在海边，翘首企盼机会的来临，而是如苍鹰一般不停的翻飞盘旋，执著的寻求。 试试看——不是面对峰回路转、杂草丛生的前途枉自嗟叹，而是披荆斩棘，举步探索。 试试看——不是拘泥于命运的禁锢，听凭命运的摆布，而是奋力敲击其神秘的门扉，使之洞开一个新的天地。微笑着，去唱生活的歌谣。

    Configure Cacti with DB user and pwd

# vim /usr/share/cacti/include/config.php
 
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactipwd";
$database_port = "3306";
$database_ssl = false;

    Create Cacti Apache configuration file

# vim /etc/apache2/conf.d/cacti.conf
 
Alias /cacti /usr/share/cacti
<Directory /usr/share/cacti >
Options None
Allow from 127.0.0.1
Allow from All
</Directory>

    Restart the apache webserver

#/etc/init.d/apache2 restart

    Finally We can log into cacti website:

    http://IP/cacti

    (use "admin" as the default username and password)

    Add a line to your /etc/crontab file similar to

# vim /etc/cron.d/cacti
*/5 * * * * cactiuser php /usr/share/cacti/poller.php > /dev/null 2>&1

    

    Configure SNMP

    For easy to let cacti to access and monitor other hosts we use below simple way to configure snmp file.

# vim /etc/snmp/snmpd.conf
rocommunity public
syslocation "Your Location"
syscontact [e-mail]

    Try to add host into Cacti and see the result.  Good luck!

    

    

文章结束给大家分享下程序员的一些笑话语录： IBM和波音777
　　波音777是有史以来第一架完全在电脑虚拟现实中设计制造的飞机，所用的设备完全由IBM公司所提供。试飞前，波音公司的总裁非常热情的邀请IBM的技术主管去参加试飞，可那位主管却说道:“啊，非常荣幸，可惜那天是我妻子的生日，So..”..
　　波音公司的总载一听就生气了:“胆小鬼，我还没告诉你试飞的日期呢!”
