选择new install
安装spine

tar xzvf cacti-spine-0.8.7a.tar.gz
cd cacti-spine-0.8.7a

编译需要libtool

rpm -ivh imake-1.0.2-3.i386.rpm
rpm -ivh autoconf-2.59-12.noarch.rpm
rpm -ivh automake-1.9.6-2.1.noarch.rpm
rpm -ivh libtool-1.5.22-6.1.i386.rpm
rpm -ivh libtool-ltdl-1.5.22-6.1.i386.rpm
rpm -ivh libtool-ltdl-devel-1.5.22-6.1.i386.rpm
./configure
make

把spine 和spine.conf copy到/usr/local/spine

mkdir /usr/local/spine
cp spine spine.conf /usr/local/spine

编辑 spine.conf 文件，输入数据库名、数据库用户名和密码等信息.
指定spine的物理路径
Console -> Configuration -> Settings -> Paths -> Alternate Poller Path -> Spine Poller File Path
路径为/usr/local/spine/spine

Cacti Plugins
Cacti插件是对cacti的扩展。
要使用cacti插件必须先扩展cacti架构，来支持插件。
安装cacti插件架构扩展
下载地址：http://cactiusers.org/downloads/
1）.解压下载的tar包，你会得到一个cacti-plugin-arch目录

# tar –zxvf cacti-plugin-arch.tar.gz
# cd cacti-plugin-arch
# ls

2）.安装插件扩展

cp cacti-plugin-0.8.7b-PA-v2.1.diff /usr/local/cacti

//备份cacti目录，以备插件扩展安装失败后能恢复到原状态

cd /usr/local
cp –r cacti ./cacti.bak
cd ./cacti

//首先使用以下命令进行测试

# patch -p1 -N --dry-run < cacti-plugin-0.8.7b-PA-v2.1.diff

//以上命令成功后，使用以下命令进行安装

# patch -p1 -N < cacti-plugin-0.8.7b-PA-v2.1.diff

将pa.sql导入数据库，支持Plugin Management

mysql --user=root --password=123456 cacti < pa.sql

3）.安装后配置，首先查看你的cacti配置文件，看cacti相关的数据库信息是否被覆盖，如果被覆盖请直接从备份中拷贝一份到配置文件目录。

# cp ../include/config.php ./include/config.php

4）.修改global.php以正常访问cacti

vi /usr/local/cacti/include/global.php

将$config['url_path'] = “/”;修改为$config['url_path'] = “/cacti/”;
注：如果cacti安装在 /var/www/html下则不用修改global.php

安装插件 下载地址为：http://cactiusers.org/downloads/
安装Monitor

tar xzvf monitor-0.8.2.tar.gz
mv monitor /usr/local/cacti/plugins/

安装插件，只需要将插件目录拷贝到cacti/plugins/目录下即可。如果是升级安装，只需要完全覆盖原插件目录即可。

vi /usr/local/cacti/include/global.php

在配置中查找$plugins = array();行，在此行下面加入：

$plugins[] = 'monitor';

注意：上面monitor的名字必须与cacti/plugins/目录下插件目录的名字相同。
在console选项卡下，点击左侧菜单中的Settings链接，在右侧出现的web页中点击Misc选项卡来配置Monitor插件。
在console - User Management – admin – 在View Monitoring前打勾

安装thold

tar xzvf thold-0.3.9.tar.gz
mv thold /usr/local/cacti/plugins/
tar xzvf settings-0.5.tar.gz
mv settings /usr/local/cacti/plugins/
vi /usr/local/cacti/include/global.php
$plugins[] = ' thold ';
$plugins[] = ' settings ';

在console – settings里修改thold相关属性
注：thold要和settings一起安装才能使用
用thold插件监控硬盘实现报警功能
适用版本cacti 0.8.7b
在cacti目录下，vi global_arrays.php
搜索custom_data_source_types，修改这一段如下：

$custom_data_source_types = array(
"CURRENT_DATA_SOURCE" => "Current Graph Item Data Source",
"ALL_DATA_SOURCES_NODUPS" => "All Data Sources (Don't Include Duplicates)",
"ALL_DATA_SOURCES_DUPS" => "All Data Sources (Include Duplicates)",
"SIMILAR_DATA_SOURCES_NODUPS" => "All Similar Data Sources (Don't Include Duplicates)",
"SIMILAR_DATA_SOURCES_DUPS" => "All Similar Data Sources (Include Duplicates)",
"CURRENT_DS_MINIMUM_VALUE" => "Current Data Source Item: Minimum Value",
"CURRENT_DS_MAXIMUM_VALUE" => "Current Data Source Item: Maximum Value",
"CURRENT_GRAPH_MINIMUM_VALUE" => "Graph: Lower Limit",
"CURRENT_GRAPH_MAXIMUM_VALUE" => "Graph: Upper Limit",
"VALUE_OF_HDD_TOTAL" => "Value of hdd_total data source");

在cacti界面的Graph Management-cdefs新建cdef模块，名字自己起，添加字段如下：

Item #1 Special Data Source: CURRENT_DATA_SOURCE
Item #2 Custom String: 100
Item #3 Operator: *
Item #4 Special Data Source: VALUE_OF_HDD_TOTAL
Item #5 Operator: /

这样就可以在Threshold Templates里面添加监控硬盘的模块了，我添加的是Host MIB - Hard Drive Space ，最后在Threshold CDEF里面选择刚自定义的cdef，这样就可以正常监控硬盘使用率了。

安装realtime

tar xzvf realtime-0.32.tar.gz
mv realtime /usr/local/cacti/plugins/
vi /usr/local/cacti/include/global.php
$plugins[] = ' realtime ';
mkdir /usr/local/cacti/rcache
chmod a+wx /usr/local/cacti/rcache

在console – settings – Misc 里修改Cache Directory的路径为/usr/local/cacti/rcache
如果安装0.34版则需要修改

1. poller_rt.php
#if (file_exists("./include/global.php")) {
# include("./include/global.php");
#} else {
# include("./include/config.php");
#}
 
include(dirname(__FILE__) . "/../../include/global.php");
 
#include_once($config["base_path"] . "/lib/poller.php");
#include_once($config["base_path"] . "/lib/data_query.php");
#include_once($config["base_path"] . "/lib/graph_export.php");
#include_once($config["base_path"] . "/lib/rrd.php");
 
include_once($config["library_path"] . "/poller.php");
include_once($config["library_path"] . "/data_query.php");
include_once($config["library_path"] . "/graph_export.php");
include_once($config["library_path"] . "/rrd.php");

2. cmd_rt.php

# include("./include/global.php");
#} else {
# include("./include/config.php");
#}
 
include(dirname(__FILE__) . "/../../include/global.php");
 
#include_once($config["base_path"] . "/lib/snmp.php");
#include_once($config["base_path"] . "/lib/poller.php");
#include_once($config["base_path"] . "/lib/rrd.php");
#include_once($config["base_path"] . "/lib/ping.php");
 
include_once($config["library_path"] . "/snmp.php");
include_once($config["library_path"] . "/poller.php");
include_once($config["library_path"] . "/rrd.php");
include_once($config["library_path"] . "/ping.php");

安装syslog
需要的软件syslog-ng 、eventlog 、libol
1. 安装syslog-ng

tar xzvf eventlog-0.2.7.tar.gz
cd eventlog-0.2.7
./configure --prefix=/usr/local/eventlog
make
make install
cd ..
tar xzvf libol-0.3.18.tar.gz
cd libol-0.3.18
./configure --prefix=/usr/local/eventlog/libol
make
make install
cd ..
tar xzvf syslog-ng-2.0.9.tar.gz
cd syslog-ng-2.0.9
export PKG_CONFIG_PATH=/usr/local/eventlog/lib/pkgconfig/
./configure --prefix=/usr/local/syslog-ng
make
make install
mkdir /usr/local/syslog-ng/etc/
cp doc/examples/syslog-ng.conf.sample /usr/local/syslog-ng/etc/syslog-ng.conf

修改syslog-ng.conf文件如下：

需要执行的bash文件如下：（脚本文件放在/usr/local/syslog-ng/sbin下）

安装cacti插件syslog

tar xzvf syslog-0.5.2.tar.gz
mv syslog-0.5.2 /usr/local/cacti/plugins/syslog
vi /usr/local/cacti/include/global.php
$plugins[] = ' syslog ';

将syslog的表导入数据库

mysql –u root –p
use cacti;
source /usr/local/cacti/plugins/syslog/syslog.sql

停止系统自带的syslog

 
pkill -9 syslog

启动syslog-ng

/usr/local/syslog-ng/sbin/syslog-ng

启动bash脚本

nohup /usr/local/syslog-ng/sbin/syslog2mysql.sh

安装advanced ping
0.8.7b本身带有ss_fping.php，需要加入一行

vi /usr/local/cacti/scripts/ss_fping.php
include_once(dirname(__FILE__) . "/../include/global_settings.php");

然后将xml模板导入到Graph Templates即可使用

NTOP

rpm -ivh libpcap-devel-0.9.4-11.el5.i386.rpm
tar xzvf ntop-3.3.6.tar.gz
cd ntop
./autogen.sh
./configure --prefix=/usr/local/ntop --with-rrd-home=/
make
make install
useradd ntop
passwd ntop
chown -R ntop.ntop /usr/local/ntop/share/ntop/
cp packages/RedHat/ntop.conf.sample /usr/local/ntop/etc/ntop/ntop.conf
/usr/local/ntop/bin/ntop -P /usr/local/ntop/share/ntop -u ntop –A
vi /usr/local/ntop/etc/ntop/ntop.conf

#程序运行用户
–user ntop
#设置ntop为服务
–daemon
#数据文件存放目录
–db-file-path /usr/local/ntop/share/ntop
#监控的网卡
–interface eth0
–trace-level 3
#web访问的端口
–http-server 3000
–disable-schedyield
启动ntop服务，指定读取的配置文件，只监控192.168.1.0/24网段
/usr/local/ntop/bin/ntop @/usr/local/ntop/etc/ntop/ntop.conf -m 192.168.1.0/24
设置开机自启动

vi /etc/rc.local
/usr/local/ntop/bin/ntop @/usr/local/ntop/etc/ntop/ntop.conf –m 192.168.1.0/24

Nagios

useradd nagios
passwd nagios
groupadd nagcmd
usermod -G nagcmd nagios
usermod -G nagcmd apache
cd /home/test/
tar xzvf nagios-3.0b6.tar.gz
cd nagios-3.0b6
./configure --prefix=/usr/local/nagios --with-gd-lib=/usr/lib --with-gd-inc=/usr/include
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagios
service httpd restart
cd ..
tar xzvf nagios-plugins-1.4.12.tar.gz
cd nagios-plugins-1.4.12
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
chkconfig --add nagios
chkconfig nagios on
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
If there are no errors, start Nagios.
service nagios start
vi /usr/local/nagios/etc/cgi.cfg

将默认的nagiosadmin修改为nagios
一开始会提示“HTTP WARNING: HTTP/1.1 403 Forbidden ”是因为nagios监控/var/www/html/下面的index.html文件，若没有就会提示错误，创建一个文件即可！
vi /var/www/html/index.html
hello !
wq
NdoUtility

rpm -ivh perl-DBD-MySQL-3.0007-1.fc6.i386.rpm
export PERL5LIB=/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/DBD

vi /usr/local/nagios/etc/ndo2db.cfg
db_user=nagios
db_pass=123456
wq

vi /usr/local/nagios/etc/nagios.cfg
修改如下：

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg
 
event_broker_options=-1
 
check_external_commands=1
 
command_check_interval=10s

启动ndo

/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
service nagios restart

tail –f /var/log/messages | grep ndo 查看log

Nagvis

cd /home/test
tar xzvf nagvis-1.2.2.tar.gz
mv nagvis-1.2.2 /usr/local/nagios/share/nagvis
You should see the directorys etc, nagvis and wui on
ls -l /usr/local/nagios/share/nagvis
cd /usr/local/nagios/share/nagvis
cp etc/nagvis.ini.php-sample etc/nagvis.ini.php
vi etc/nagvis.ini.php

去掉注释
wq
check which unix user account is used to run your webserver (in my case it is apache).

grep -e '^User' /etc/httpd/conf/*
 
chown apache:apache /usr/local/nagios/share/nagvis -R
chmod 664 /usr/local/nagios/share/nagvis/etc/nagvis.ini.php
chmod 775 /usr/local/nagios/share/nagvis/nagvis/images/maps
chmod 664 /usr/local/nagios/share/nagvis/nagvis/images/maps/*
chmod 775 /usr/local/nagios/share/nagvis/etc/maps
chmod 664 /usr/local/nagios/share/nagvis/etc/maps/*

http:///nagvis/config.php

若安装nagvis-1.3需要安装以下rpm用作支持automap
