cacti如何配置，网上好多教程讲的都不全，配置都不成功

cacti0.8.7e安装：

1、必备的人品吗安装包：

httpd、mysql-server、php、php-mysql、rrdtool、gd、net-snmp、php-snmp、net-snmp-utils、net-snmp-devel、mysql-devel、openssl-devel

2、各个RPM安装包的作用：

httpd：WEB服务器apache

mysql-server：mysql数据库

php：php环境

php-mysql：使php支持mysql

rrdtool：用来生成cacti图像

gd：rrdtool绘制图像需要的图形库

net-snmp：安装snmp

php-snmp：php支持snmp

net-snmp-utils：一些snmp扩展命令，如snmpwalk，snmpget等，cacti需要

net-snmp-devel、mysql-devel、openssl-devel： cactid/spine需要

3.安装时可以使用yum进行安装

4.安装完成后启动相关服务

service httpd start

service mysqld start

service snmpd start

chkconfig httpd on

chkconfig mysqld on

chkconfig snmpd on

二、mysql数据配置

启动并初始化mysql数据库

#service mysqld start

为root用户设置密码(以linuxpad为例)，并更改登录权限，默认密码为空

#mysql –u root –p 回车后输入密码(空)

mysql>use mysql

mysql>update user set password=password(‘linuxpad’) where user=‘root’

mysql>grant all privileges on *.* to root@localhost identified by ‘linuxpad’ with grant option

mysql>flush privileges

添加cacti库和cacti用户，并为其设置权限

mysql>create database cacti default character set utf8 //数据库字符集设置utf8，否则乱码

mysql>grant all privileges on cacti.* to cacti@localhost identified by ‘linuxpad’ with grant option

mysql>flush privileges

三、安装cacti

1、

cd /root

wget http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz

2、解压到/var/www/html下

#cd /root

#tar zxvf cacti-0.8.7e.tar.gz

#mv cacti-0.8.7e /var/www/html/cacti-0.8.7e

修改配置文件

#vi /var/www/html/cacti0.8.7e/include/config.php

修改内容如下

$database_type = "mysql"

$database_default = "cacti"

$database_hostname = "localhost"

$database_username = "cacti"

$database_password = "linuxpad"

添加一个cacti用户，更改rra和log目录属主为cacti，

chown -R cacti /var/www/html/cacti-0.8.7e/log

chown -R cacti /var/www/html/cacti-0.8.7e/rra

然后在cacti用户环境下设置crontab，crontab -e

内容为:

*/5 * * * * php /var/www/cacti/poller.php >/dev/null &2>1

apache2.2.8+mysql5.0.51+php5.2.5+snmp5.14+rrdtool+cacti 配置

OS fedora7 安装选包定制

全选开发包

服务器 一个没选

安装 mysql

所有安装程序 在 /usr/local下

[root@localhost usr]# groupadd mysql

[root@localhost usr]# useradd -g mysql mysql

[root@localhost usr]# cd /usr/local

[root@localhost local]# tar -zxvf mysql-5.0.51.tar.gz

[root@localhost local]# cd mysql-5.0.51

[root@localhost mysql-5.0.51# ./configure --prefix=/usr/local/mysql

[root@localhost mysql-5.0.51]# make

[root@localhost mysql-5.0.51]# make install

[root@localhost mysql-5.0.51]# cd ../mysql

[root@localhost mysql]# scripts/mysql_install_db --user=mysql

[root@localhost mysql]# chown -R root .

[root@localhost mysql]# chown -R mysql var

[root@localhost mysql]# chgrp -R mysql .

[root@localhost mysql]# ./bin/mysqld_safe --user=mysql &

[root@localhost mysql]# ./bin/mysqladmin -uroot password mysql

[root@localhost mysql]# cp ../mysql-5.0.51/support-files/my-large.cnf /etc/my.cnf

[root@localhost mysql]# cp ../mysql-5.0.51/support-files/mysql.server /etc/rc.d/init.d/mysqld

[root@localhost mysql]# chkconfig --add mysqld

[root@localhost mysql]# chkconfig --level mysqld 345 on

[root@localhost mysql]# chkconfig --list mysqld

[root@localhost mysql]#

Mysql 安装结束

安装apache

[root@localhost usr]# tar -zxvf httpd-2.2.8.tar.gz

[root@localhost usr]# cd httpd-2.2.8

[root@localhost httpd-2.2.8]# ./configure --prefix=/usr/local/apache --enable-mods-shared=all --enable-so

[root@localhost httpd-2.2.8]# makemake install

[root@localhost httpd-2.2.8]# cp /usr/local/apache/bin/apachectl /etc/init.d/httpd

[root@localhost httpd-2.2.8]# cd /etc/rc3.d

[root@localhost rc3.d]# ln -s /etc/init.d/httpd S85httpd

[root@localhost rc3.d]# ln -s /etc/init.d/httpd K85httpd

[root@localhost rc3.d]# /usr/local/apache/bin/apachectl star

Apache 安装完毕

mysql>create database cactidb

mysql>grant all on cactidb.* to root

mysql>grant all on cactidb.* to root@localhost

Mysql设置完毕

检测apache + php + mysql

[root @tsai usr]# cd /www/htdocs

[root @tsai htdocs]# touch info.php

[root @tsai htdocs]# vi info.php

<?

phpinfo( )

?>

保存退出 ：wq

[root @tsai htdocs]# touch mydqltest.html

[root @tsai htdocs]# vi mysqltest.html

<?}?>

</body>

</html>

保存退出 ：wq

重启mysql + apache 服务

[root @localhost htdocs]# service mydql restart

[root @localhost htdocs]# service httpd restart

进入浏览器检查

http://192.168.1.254/info.php 和 http://192.168.1.254/mysqltest.html

安装rrdtool

[root@localhost usr]# tar zxvf rrdtool-1.0.50.tar.gz

[root@localhost usr]# cd rrdtool-1.0.50

[root@localhost rrdtool-1.0.50]# ./configure

[root@localhost rrdtool-1.0.50]# make &&make install

我的是fedora 7,用下面的方法。

[root@localhost usr] yum install rrdtool

Rrdtool安装完毕

安装net-snmp、snmpwalk和snmpget命令

[root@localhost usr]# rpm -qa | grep net-snmp

net-snmp-5.0.9-2.30E.15

net-snmp-devel-5.0.9-2.30E.15

net-snmp-libs-5.0.9-2.30E.15

net-snmp-utils-5.0.9-2.30E.15

[root@localhost usr]# vi /etc/snmp/snmpd.conf

更改 1、com2sec notConfigUser default public

改为：com2sec notConfigUser 127.0.0.1 public

2、access notConfigGroup "" any noauthexact systemview none none

改为：access notConfigGroup "" any noauthexact all none none

3、#view allincluded .1 80

将前面的 # 注释 去掉。

保存退出 :wq

[root@localhost usr]# service snmpd restart

使用yum安装更方便：

[root@localhost usr]# yum install net-snmp

[root@localhost usr]# yum update net-snmp

配置还是使用上面的方法修改。

或者使用：net-snmp-5.1.4.tar.gz安装

[root@localhost local]# tar -zxvf net-snmp-5.1.4.tar.gz

[root@localhost local]# cd net-snmp-5.1.4

[root@localhost local]# ./configure

[root@localhost local]# make

[root@localhost local]# make install

运行snmpconf -g basic_setup，会在当前目录下生成一个snmpd.conf配置文件：

[root@localhost local]# snmpconf -g basic_setup

运行后会出现一个询问菜单，按如下步骤进行回答：CODE:[Copy to clipboard]Do you want to configure the information returned in

the system MIB group (contact info, etc)? (default = y): y

Do you want to configure the agents ability to monitor file sizes? (default = y): n（如果想监控文件的大小，可以选y）

4．运行net-snmp：

# snmpd -c /path/snmpd.conf (要上面生成的绝对路径)

测试一下看看net-snmp是否配置成功：

#snmpwalk -v 1 -c public localhost .1 (是否可以从.1开始采集服务器数据)

#snmpwalk -v 1 -c public localhost dskPercent.1 (看看刚配置过的硬盘监测是否成功)

如果有数据了，恭喜你snmp安装成功了。

注：如果你机器内没有snmpwalk和snmpge命令，请到安装盘里查找 net-snmp-utils 包，rpm -ivh net-snmp-utils-*.rpm 只后这两个命令就

在系统里了。其他包也都在安装盘里 确保安装这四个包就OK

安装/ 配置cacti

[root@localhost usr]# useradd cactiuser -g users

[root@localhost usr]# passwd cactiuser (pwd:cactipw)

[root@localhost usr]# cp cacti-0.8.7.tar.gz /var/www/html

[root@localhost usr]# cd /var/www/html

[root@localhost html]# tar -zxvf cacti-0.8.7.tar.gz

[root@localhost html]# mv cacti-0.8.6g cacti

[root@localhost html]# cd cacti

[root@localhost cacti]# /usr/local/mysql/bin/mysql -u root -p cactidb <cacti.sql

passwork:

[root@localhost cacti]# chown -R cactiuser rra/ log/

[root@localhost cacti]# cd scripts

[root@localhost scripts]# chown cactiuser:users *

[root@localhost scripts]# vi /www/htdocs/cacti/include/config.php

$database_type = “mysql”

$database_default = “cactidb”

$database_hostname = “localhost”

$database_username = “cactiuser”

$database_password = “cactipw”

更改用户、密码 等项 与上面给出的对应 保存退出

[root@localhost scripts]# crontab -u cactiuser -e

加入

*/5 * * * * /usr/local/php/bin/php /var/www/html/cacti/poller.php >/dev/null 2>&1

保存退出：wq

全部设置完毕。

打开浏览器 http://192.168.1.254/cacti 进入cacti的初始设置页面

第一次默认登陆账号：admin 密码 admin

登陆后在新改个密码就OK

需要说明的还有路径

snmpwalk Binary Path ： /usr/bin/snmpwalk

snmpget Binary Path： /usr/bin/snmpget

RRDTool Binary Path： /usr/bin/rrdtool

PHP Binary Path： /usr/local/php/bin/php

Cacti Log File Path： /var/www/html/cacti/log/cacti.log

Cactid Poller File Path：/var/www/html/cacti/poller.php

如果你是按我的步骤做的 那上面的路径一定不会错。

注：此时graphs还不能显示图形，需要将服务重新启动一下

[root@localhost scripts]# service snmpd restart

[root@localhost scripts]# service mysql restart

[root@localhost scripts]# service httpd restart

如果在CACTI里安装了NAGIOS的插件，那么在NASGIS里添加完的主机会直接出现CACTI里。反之则不可以。另外，CACTI主要功能是做数据统计，NAGIOS主要是做系统状态预警。

防止入侵，如果是WINDOWS里策略里加审核就行了，在非指定的用户进入系统后，自动触发一封邮件出来，或自动发送一条TRAP到CACTI或NAGIOS.
