tar zxvf rrdtool-1.2.11.tar.gz

cd rrdtool-1.2.11

./configure --prefix=/usr/local/rrdtool-1.2.11 \

--disable-tcl \

--disable-python

make

make install

3、 安装net-snmp、snmpwalk和snmpget

SNMP安装和配置

          (1).windows server 2003

                   打开控制面板——添加或删除程序——添加或删除windows组件，选择“管理和监视工具”中的“简单网络管理协议(SNMP)”，点确定，点下一步进行安装，安装完之后要打开控制面板——管理工具——服务，打开SNMP Service的属性，在安全选项卡里的“接受团体名称”中添加一个权限为只读的irunnet团体，然后选择“接受来自任何主机的SNMP数据包”点确定，重新启动SNMP Service服务

         (2).windows 2000

                  打开控制面板——添加或删除程序——添加或删除windows组件，选择“管理和监视工具”中的“简单网络管理协议”，点确定，点下一步进行安装，安装完之后要打开控制面板——管理工具——服务，打开SNMP Service的属性，在安全选项卡里的“接受团体名称”中把public改成irunnet，重新启动SNMP Service服务

         (3).redhat

         如果系统安装的时候没有安装可以先装一个apt,然后用apt-get install net-snmp来安装

修改配置文件

       vi /etc/snmp/snmpd.conf

       修改如下两行

         com2sec notConfigUser  default       irunnet

access  notConfigGroup ""      any       noauth    exact  mib2 none none

去掉下面几行前面的“#”

com2sec local     localhost       COMMUNITY

com2sec mynetwork NETWORK/24      COMMUNITY

group MyRWGroup  any        local

group MyROGroup  any        mynetwork

view all    included  .1                               80

view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc

access MyROGroup ""      any       noauth    0      all    none   none

access MyRWGroup ""      any       noauth    0      all    all    all

开启：

setup

在system service选中snmp

         (4).freebsd

         Vi /usr/local/share/snmp/snmpd.conf添加如下一行

rocommunity  irunnet

4、 安装、配置cacti

(1). 解压

cd /usr/local/apps/www/

wget http://www.cacti.net/downloads/cacti-0.8.6g.tar.gz

tar zxvf cacti-0.8.6g.tar.gz

mv cacti-0.8.6g cacti

cd cacti

(2).打补丁

wget http://www.cacti.net/downloads/patches/0.8.6g/short_open_tag_parse_error.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/graph_properties_zoom.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/script_server_snmp_auth.patch

wget http://www.cacti.net/downloads/patches/0.8.6g/mib_file_loading.patch

patch -p1 -N < short_open_tag_parse_error.patch

patch -p1 -N < graph_properties_zoom.patch

patch -p1 -N < script_server_snmp_auth.patch

patch -p1 -N < mib_file_loading.patch

(3)建cacti库

[root@irunnet cacti]#mysqladmin --user=root create cacti

(4)导入cacti.sql

[root@irunnet cacti]#mysql cacti < cacti.sql

(5)对cacti库授权

      [root@irunnet cacti]# mysql --user=root mysql

      mysql> GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY 'cacti';

      mysql> flush privileges;

(6)修改cacti配置文件、连接MYSQL

编辑cacti/include/config.php

/* make sure these values refect your actual database/host/user/password */

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = "cacti";

(7)对cacti中rra,log文件夹权限稍加修改

 [root@irunnet cacti]# chown -R cacti rra/ log/[请事先在OS中添加cacti用户]

  (8) 定时运行cacti采集数据

       /etc/crontab -e

       添加一行：

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

(9) 测试

[root@irunnet cacti]cd include

[root@localhost include]# /usr/local/php/bin/php /usr/local/data/www/cacti/poller.php

OK u:0.00 s:0.01 r:2.03

OK u:0.01 s:0.01 r:6.15

OK u:0.01 s:0.01 r:6.15

OK u:0.01 s:0.01 r:7.16

12/08/2005 12:24:02 AM - SYSTEM STATS: Time:7.2343 Method:cmd.php Processes:1 Threads:N/A Hosts:3 HostsPerProcess:3 DataSources:27 RRDsProcessed:21

说明正常，已经开始采集数据

当测试时候出现如下错误时候

PHP Warning:  mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /usr/local/apps/www/cacti/lib/adodb/drivers/adodb-mysql.inc.php on line 340

…………………………………………………………………………..

等主要是和mysql连接出现故障，将mysql.sock连接到/var/lib/mysql/mysql.sock即可 [注意写全路径，mysql默认安装sock在/tmp下]

ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

(10)监控页面初始配置

http://www.irunnet.com/******/cacti

初始安装next----new install—配置路径[请修改：RRDTool Binary Path：/usr/local/rrdtool-1.2.11/bin/rrdtool，其他的默认路径都应该OK]—登陆[默认用户名密码都是admin]

进去之后请更改settings选项中的几个参数

RRDTool Utility Version默认是RRDTool 1.0.x请改为RRDTool 1.2.x

SNMP Version默认是Version 1请改为Version 2

SNMP Community 请设置为你自己想要的如irunnet

(11)如何进行监控，参考http://www.cacti.net/downloads/docs/html/basics.html

Step 4:添加启动脚本

echo "cd /usr/local/apache2/bin;./apachectl start">>/etc/rc.local

echo "cd /usr/local/mysql/bin;./mysqld_safe & ">>/etc/rc.local
