RHEL5.4下cacti及相關插件的編譯安裝

一、概述

1. Cacti 是用php 語言實現的一個軟件，它的主要功能是用snmp 服務獲取數據，

然後用rrdtool 儲存和更新數據，當用戶需要查看數據的時候用rrdtool 生成圖表

呈現給用戶。因此，snmp 和rrdtool 是cacti 的關鍵。snmp 關係着數據的收集，

rrdtool 關係着數據存儲和圖表的生成。

2. Mysql 配合PHP 程序存儲一些變量數據並對變量數據進行調用，如：主機名、主

機ip、snmp 團體名、端口號、模板信息等變量。

3. snmp 抓到數據不是存儲在mysql 中，而是存在rrdtool 生成的rrd 文件中（在

cacti 根目錄的rra 文件夾下）。rrdtool 對數據的更新和存儲就是對rrd 文件的處

理，rrd 文件是大小固定的檔案文件（Round Robin Archive），它能夠存儲的數據筆數

在創建時就已經定義。

二、Cacti的架構及工作流程

1. Cacti 的架構

2. Cacti 的工作流程

 

安裝需求：(cacti相關包下載地址：http://www.cacti.net/downloads/)

        ·         RRDTool 1.2.x 或者更高

·         MySQL 4.1.x or 5.x 或者更高

·         PHP 4.3.6 或者更高（推薦5.3以下，否則會報很多錯誤） php-mysql  php-snmp

·         Web服務 例如：Apache 或者 IIS

·         net-snmp

php編譯配置時需要添加下列模塊：(可用php –m查看這些模塊是否安裝)

·         mysql

·         snmp

·         xml

·         session

·         sockets

·         gd (安裝一些插件時需要)

·         LDAP (當用LDAP認證時需要,非必須)

 

安裝過程步驟：

1.安裝必需組件

yum install –y  fontconfig* autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel libart_lgpl* pango* libtool* ncurses ncurses-devel curl curl-devel openssl openssl-devel  perl*  net-snmp*

 

2. 安裝mysql

查看系統中是否已經安裝了MySQL，如果是卸載所有以mysql 開頭的包。

yum remove –y mysql*

tar -zxvf mysql-5.1.44.tar.gz  -C /usr/local/src

useradd mysql

cd  /usr/local/src/mysql-5.1.44

./configure --prefix=/usr/local/cacti/mysql  --enable-local-infile --with-charset=gbk

 --with-low-memory  --with-mysqld-user=mysql --enable-thread-safe-client

make && make install

cp /usr/local/src/mysql-5.1.44/support-files/my-medium.cnf  /etc/my.cnf

chown -R mysql:mysql   /usr/local/cacti/mysql/

/usr/local/cacti/mysql/bin/mysql_install_db --user=mysql

/usr/local/cacti/mysql/bin/mysqld_safe --user=mysql &

echo "/usr/local/cacti/mysql/lib/mysql" >> /etc/ld.so.conf

cp  /usr/local/src/mysql-5.1.44/support-files/mysql.server  /etc/init.d/mysqld

ln -s /usr/local/cacti/mysql/bin/mysql  /usr/local/bin/mysql

ldconfig -v | grep mysql

chmod 755 /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld on

 

3.安裝Apache

tar -zxvf httpd-2.2.15.tar.gz  -C /usr/local/src

cd  /usr/local/src/httpd-2.2.15

./configure --prefix=/usr/local/cacti/apache --enable-so --enable-rewrite  --enable-ssl --with-ssl=/usr/bin/openssl --with-zlib --enable-mods-shared=all --enable-track-vars --with-mysql=/usr/local/cacti/mysql

make && make install

/usr/local/cacti/apache/bin/apachectl start

ln -s /usr/local/cacti/apache/bin/apachectl  /etc/init.d/httpd 

vi /etc/init.d/httpd  //添加如下兩行

#description:http server

#chkconfig: 2345 83 17

chkconfig --add httpd

chkconfig httpd on

添加php支持

vi /usr/local/cacti/apache/conf/httpd.conf

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

<IfModule dir_module>

DirectoryIndex index.php index.html

</IfModule>

 

4.安裝php

tar -zxvf php-5.2.8tar.gz  -C  /usr/local/src

cd /usr/local/src/php-5.2.8

./configure   --prefix=/usr/local/cacti/php --with-config-file-path=/usr/local/cacti/php

--with-apxs2=/usr/local/cacti/apache/bin/apxs --with-zlib --with-bz2 --with-freetype-dir --enable-mbstring --with-mysql=/usr/local/cacti/mysql --with-mysqli=/usr/local/cacti/mysql/bin/mysql_config --with-gd --with-libxml-dir --with-png-dir --with-jpeg-dir --enable-sockets --with-snmp

make && make install

cp php.ini-dist  /usr/local/cacti/php/php.ini

ln -s /usr/local/cacti/php/bin/php  /usr/bin

vim  /usr/local/cacti/apache/htdocs/index.php

<?

phpinfo();

?>

 

5.安裝rrdtool

yum install –y intltool   //先更新intltool

tar -zxvf rrdtool-1.3.9.tar.gz

cd rrdtool-1.3.9

./configure --prefix=/usr/local/cacti/rrdtool

make && make install

 

6.安裝spine

tar -zxvf cacti-spine-0.8.7e.tar.gz

cd cacti-spine-0.8.7e

./configure --prefix=/usr/local/cacti/spine --with-mysql=/usr/local/cacti/mysql

make && make install

cat  /usr/local/cacti/spine/etc/spine.conf

DB_Host localhost

DB_Database cacti

DB_User cactiuser

DB_Pass cactiuser

DB_Port 3306

 

7.安裝cacti並創建cacti數據庫

tar -zxvf cacti-0.8.7e.tar.gz

mv cacti-0.8.7e /usr/local/cacti/apache/htdocs/cacti

chown –R  root:root /usr/local/cacti/apache/htdocs/cacti

cat  /usr/local/cacti/apache/htdocs/cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactiuser";

$database_port = "3306";

cat  /usr/local/cacti/apache/htdocs/cacti/include/global.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactiuser";

$database_port = "3306";

useradd cactiuser

/usr/local/bin/mysql

mysql> create database cacti;

mysql> grant all privileges on cacti.* to cactiuser@localhost identified by "cactiuser";

mysql>flush privileges;      

mysql cacti < /usr/local/cacti/apache/htdocs/cacti/cacti.sql   //導入數據庫

 

8.定時執行

crontab -e

*/5 * * * *  php /usr/local/cacti/apache/htdocs/cacti/poller.php > /dev/null 2>&1

9.在瀏覽器中輸入http://serverIP/cacti 安裝配置cacti

設置完後用http://serverIP/cacti/登錄,默認用戶名和密碼都是admin,第一次登錄要求強制修改密碼

 

安裝後的Settings設置,需要注意net-snmp,roodtool的版本號.spine路徑,poller type,如下:

以下是一些插件的安裝，用於擴展功能

10.安裝Plugin Architecture

unzip cacti-plugin-0.8.7e-PA-v2.5.zip

/usr/local/bin/mysql cacti < pa.sql

cp cacti-plugin-0.8.7e-PA-v2.5.diff /usr/local/cacti/apache/htdocs/cacti/

cd /usr/local/cacti/apache/htdocs/cacti/

patch -p1 -N < cacti-plugin-0.8.7e-PA-v2.5.diff

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

$config['url_path']='/';改成

$config['url_path']='/cacti/';

User Management-->admin-->選中Plugin Management 保存

刷新頁面，左側configuratin的Settings下面會顯示Plugin Managemnet

11.settings插件的安裝

tar -zxvf settings-0.5.tgz

mv settings-0.5 /usr/local/cacti/apache/htdocs/cacti/plugins/settings

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

$plugins=array();找到這一項，添加

$plugins[] = 'settings';

$plugins[] = 'weathermap';

$plugins[] = 'monitor';

$plugins[] = 'thold';

$plugins[] = 'ntop';

$plugins[] = 'syslog';

$plugins[] = 'discovery';

點擊左側--->Plugin Management-->在新打開的窗口中會顯示剛安裝的settings插件，如圖:

必須Install再Enable才能使用

 

13.weathermap插件的安裝

unzip php-weathermap-0.97.zip

mv weathermap/ /usr/local/cacti/apache/htdocs/cacti/plugins/weathermap

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

$plugins=array();找到這一項，添加

$plugins[]='weathermap';

cd /usr/local/cacti/apache/htdocs/cacti/plugins/weathermap

chown cactiuser output

cp editor-config.php-dist editor-config.php

ps -aux | grep httpd

chown daemon configs/

chmod u+w configs/

vi editor-config.php

$cacti_base = "/usr/local/cacti/apache/htdocs/cacti";

$cacti_url = "http://192.168.0.161/cacti/";

$mapdir= $cacti_base.'/plugins/weathermap/configs';

$ignore_cacti = FALSE;

將editor.php中的ENABLED=false改爲true，否則weathermap點擊Editor時會報錯

vim /usr/local/cacti/apache/htdocs/cacti/plugins/weathermap/editor.php

//$ENABLED=false; 將false改爲true

$ENABLED=true;

 

14.monitor的安裝

tar -zxvf monitor-latest.tgz

mv monitor-0.9/ /usr/local/cacti/apache/htdocs/cacti/plugins/monitor

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

$plugins=array();找到這一項，添加

$plugins[]='monitor';添加

 

15.thold的安裝

tar -zxvf thold-latest.tgz

mv thold-0.41/ /usr/local/cacti/apache/htdocs/cacti/plugins/thold

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

$plugins=array();找到這一項，添加

$plugins[]='thold';添加

在Plugin Managment中，將剛安裝的monitor,thold Install-->Enable 就可以看到monitor thold的標籤了

16. notp的安裝

安裝ntop之前要安裝libpcap和rrdttool

tar -zxvf libpcap-1.1.1.tar.gz

cd libpcap-1.1.1

./configure

make && make install

tar -zxvf ntop-3.3.tar.gz

cd ntop-3.3

./autogen.sh --with-rrd-home=/usr/local/cacti/rrdtool --disable-snmp

./configure --prefix=/usr/local/ntop --with-rrd-home=/usr/local/cacti/rrdtool --disable-snmp

make && make install

cp packages/RedHat/ntop.conf.sample /etc/ntop.conf

配置ntop

groupadd ntop

useradd ntop -g ntop

mkdir /var/log/ntop

chown -R ntop.ntop /usr/local/share/ntop

chown -R ntop.ntop /var/log/ntop

mkdir /usr/local/var/ntop/rrd

chmod -R 777 /usr/local/var/ntop/rrd/

ln -s /usr/lib64/libpcap.so.0.9.4 /lib64/libpcap.so.1

ldconfig

/usr/local/ntop/bin/ntop -A

echo "/usr/local/ntop/bin/ntop -p /var/log/ntop & 2>1 1> /dev/null" >> /etc/rc.local

配置完成.

IP輸入: http://192.168.0.200:3000 就OK 了.

tar -zxvf ntop-0.1.tar.gz

mv ntop /usr/local/cacti/apache/htdocs/cacti/plugins/ntop

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

 

$plugins=array();找到這一項，添加

$plugins[]='ntop';添加

User Management-->admin-->View NTop

 

17.syslog安裝，可以做爲日誌服務器

tar -zxvf syslog-0.5.2.tar.gz

mv syslog /usr/local/cacti/ap

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

$plugins=array();找到這一項，添加

$plugins[]='syslog';添加

 

vim /usr/local/cacti/apache/htdocs/cacti/plugins/syslog/config.php

$syslogdb_type = 'mysql';

$syslogdb_default = 'syslog';

$syslogdb_hostname = 'localhost

$syslogdb_username = 'cactiuser';

$syslogdb_password = 'cactiuser';

//建立syslog數據庫及用syslog.sql建表等

/usr/local/bin/mysql

mysql> create database syslog;

mysql> quit;

/usr/local/bin/

mysql> grant all privileges on syslog.* to cactiuser@localhost identified by "cactiuser";

mysql> flush privileges;

mysql> exit;

 

service syslog stop

安裝rpm -ivh syslog

vi /etc/syslog-ng/syslog-ng.conf

# 在文件末尾添加如下內容

source net {

udp();

};

destionation d_mysql{

pipe("/tmp/mysql.pipe”)

template("INSERT INTO

'$FACILITY', '$PRIORITY', '$YEAR-$MONTH-$DAY', '$HOUR:$MIN:$SEC', '$MSG' );\n") template-escape(yes)

);

};

log { source(net); destination(d_mysql); }

log { source(s_sys); destination(d_mysql); }

shell配置

vim  /sbin/syslogtomysql

#!/bin/bash

if [ ! -e /tmp/mysql.pipe];then

mkfifo /tmp/mysql.pipe

fi

while[-e /tmp/mysql.pipe]

do

   mysql –u cactiuser –password=cactiuser syslog </tmp/mysql.pipe

done

chmod 755 /sbin/syslogtomysql

echo "/sbin/syslogtomysql &" >> /etc/rc.local

/sbin/syslogtomysql &

service syslog-ng restart

service mysqld restart

chkconfig syslog off

chkconfig --del syslog

chkconfig syslon-ng on

chkconfig --add syslog-n

點擊syslog標籤會有php的警告信息，經查找，是syslog.php中timespan_settings.php的路徑不對，懷疑是版本問題導致

vim /usr/local/cacti/apache/htdocs/cacti/plugins/syslog/syslog.php

include($syslog_config["graphtime"] ? "./lib/timespan_settings.php

"plugins/syslog/html/syslog_timespan_settings.php"); //改爲上面的路/*include($syslog_config["graphtime"] ? "./include/html/inc_timespan_settings.

"plugins/syslog/html/syslog_timespan_settings.php");*/

18.discovery的安裝

tar -zxvf discovery-0.8.5.tar.gz

mv discovery /usr/local/cacti/apache/htdocs/cacti/plugins/discovery

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

$plugins=array();找到這一項，添加

$plugins[]='discovery';添加
