RHEL5.4下cacti及相關外掛的編譯安裝
一、概述
1. Cacti 是用php 語言實現的一個軟體，它的主要功能是用snmp 服務獲取資料，
然後用rrdtool 儲存和更新資料，當用戶需要檢視資料的時候用rrdtool 生成圖表
呈現給使用者。因此，snmp 和rrdtool 是cacti 的關鍵。snmp 關係著資料的收集，
rrdtool 關係著資料儲存和圖表的生成。
2. Mysql 配合PHP 程式儲存一些變數資料並對變數資料進行呼叫，如：主機名、主
機ip、snmp 團體名、埠號、模板資訊等變數。
3. snmp 抓到資料不是儲存在mysql 中，而是存在rrdtool 生成的rrd 檔案中（在
cacti 根目錄的rra
理，rrd 檔案是大小固定的檔案檔案（Round Robin Archive），它能夠儲存的資料筆數
在建立時就已經定義。
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
· Web服務 例如：Apache 或者 IIS
· net-snmp
php編譯配置時需要新增下列模組：(可用php –m檢視這些模組是否安裝)
· mysql
· snmp
· xml
· session
· sockets
· gd (安裝一些外掛時需要)
· LDAP (當用LDAP認證時需要,非必須)
安裝過程步驟：
1.安裝必需元件
yum install –y fontconfig* autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel
2. 安裝mysql
檢視系統中是否已經安裝了MySQL，如果是解除安裝所有以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 //新增如下兩行
#description:http server
#chkconfig: 2345 83 17
chkconfig --add httpd
chkconfig httpd on
新增php支援
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並建立cacti資料庫
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 [email protected] identified by "cactiuser";
mysql>flush privileges;
mysql cacti < /usr/local/cacti/apache/htdocs/cacti/cacti.sql //匯入資料庫
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
設定完後用http://serverIP/cacti/登入,預設使用者名稱和密碼都是admin,第一次登入要求強制修改密碼
安裝後的Settings設定,需要注意net-snmp,roodtool的版本號.spine路徑,poller type,如下:
以下是一些外掛的安裝，用於擴充套件功能
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 儲存
重新整理頁面，左側configuratin的Settings下面會顯示Plugin Managemnet
11.settings外掛的安裝
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，新增
$plugins[] = 'settings';
$plugins[] = 'weathermap';
$plugins[] = 'monitor';
$plugins[] = 'thold';
$plugins[] = 'ntop';
$plugins[] = 'syslog';
$plugins[] = 'discovery';
點選左側--->Plugin Management-->在新開啟的視窗中會顯示剛安裝的settings外掛，如圖:
必須Install再Enable才能使用
13.weathermap外掛的安裝
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，新增
$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';
$ignore_cacti = FALSE;
將editor.php中的ENABLED=false改為true，否則weathermap點選Editor時會報錯
vim /usr/local/cacti/apache/htdocs/cacti/plugins/weathermap/editor.php
//$ENABLED=false; 將false改為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，新增
$plugins[]='monitor';新增
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，新增
$plugins[]='thold';新增
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

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，新增
$plugins[]='ntop';新增
User Management-->admin-->View NTop
17.syslog安裝，可以做為日誌伺服器
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，新增
$plugins[]='syslog';新增
vim /usr/local/cacti/apache/htdocs/cacti/plugins/syslog/config.php
$syslogdb_type = 'mysql';
$syslogdb_default = 'syslog';
$syslogdb_hostname = 'localhost
$syslogdb_username = 'cactiuser';
$syslogdb_password = 'cactiuser';
//建立syslog資料庫及用syslog.sql建表等
/usr/local/bin/mysql
mysql> create database syslog;
mysql> quit;
/usr/local/bin/
mysql> grant all privileges on syslog.* to [email protected] identified by "cactiuser";
mysql> flush privileges;
mysql> exit;
service syslog stop
安裝rpm -ivh syslog
vi /etc/syslog-ng/syslog-ng.conf
# 在檔案末尾新增如下內容
source net {
udp();
};
destionation d_mysql{
pipe("/tmp/mysql.pipe”)
template("INSERT INTO
'$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
點選syslog標籤會有php的警告資訊，經查詢，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($syslog_config["graphtime"] ? "./lib/timespan_settings.php
"plugins/syslog/html/syslog_timespan_settings.php"); //改為上面的路/*include($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，新增
$plugins[]='discovery';新增
