cacti安装与配置（转）。

一、准备所需要的软件包

Apache http://www.apache.org/

Mysql http://www.mysql.com/

Php http://www.php.net

Rrdtool http://oss.oetiker.ch/rrdtool/

Net-snmp http://www.net-snmp.org/

Cacti http://www.cacti.net/

其中apache、mysql、php通过yum安装

二、安装所需要的软件

1.安装LAMP

[[email protected] ~]# yum -y install httpd mysql-server php php-mysql mysql-devel

[[email protected] ~]# chkconfig httpd on

[[email protected] ~]# chkconfig mysqld on

[[email protected] ~]# /etc/init.d/httpd start

[[email protected] ~]# /etc/init.d/mysqld start

安装完成后，可通过以下程序测试

[[email protected] html]# cat inex.php

<?php

phpinfo();

2.安装rrdtool

Rrdtool安装需要cairo、libxml2、pango库支持，可通过yum安装

[[email protected] ~]# yum -y install cairo-devel libxml2-devel pango-devel

[[email protected] ~]# tar zxvf rrdtool-1.4.7.tar.tar

[[email protected] ~]# cd rrdtool-1.4.7

[[email protected] rrdtool-1.4.7]# ./configure --prefix=/usr/local/rrdtool

[[email protected] rrdtool-1.4.7]# make && make install

[[email protected] rrdtool-1.4.7]# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/

3.安装net-snmp

[[email protected] ~]# tar zxvf net-snmp-5.6.1.1.tar.gz

[[email protected] ~]# cd net-snmp-5.6.1.1

[[email protected] net-snmp-5.6.1.1]# ./configure --prefix=/usr/local/net-snmp

[[email protected] net-snmp-5.6.1.1]# make && make install

[[email protected] net-snmp-5.6.1.1]# cp EXAMPLE.conf /etc/snmpd.conf

[[email protected] ~]# ln -s /usr/local/net-snmp/bin/* /usr/local/bin/

[[email protected] ~]# vim /etc/snmpd.conf

rocommunity public localhost #去掉注释

[[email protected] ~]# /usr/local/net-snmp/sbin/snmpd -c /etc/snmpd.conf

加入开机启动

[[email protected] ~]# echo "/usr/local/net-snmp/sbin/snmpd -c /etc/snmpd.conf " >>/etc/rc.local

(这里可以通过yum安装net-snmp）

4.安装cacti

[[email protected] ~]# tar zxvf cacti-0.8.7i-PIA-3.1.tar.gz

[[email protected] ~]# mv cacti-0.8.7i-PIA-3.1/* /var/www/html/ (这里不是要拷贝到/var/www/html，而是要在html下建立一个cacti文件夹，然后把所有内容全部拷贝过去 cp -rf cacti-0.8.7i-PIA-3.1/* /var/www/html/cacti/）

#将cacti中的内容移到 web目录

[[email protected] ~]# chown -R apache:apache /var/www/html/

[[email protected] ~]# mysql -uroot

#连接到mysql创建数据库

mysql> create database cacti;

#创建cacti数据库

mysql> insert into mysql.user(host,user,password) values ('localhost','cacti',password('cacti123'));

#建立用户cacti，密码cacti123

mysql> flush privileges;

#重载mysql授权表

mysql> grant all on cacti.* to [email protected]'localhost' identified by 'cacti123';

#把数据库cacti授权于用户cacti
