我把我的文档给你看看吧
Cacti配置文档
所需软件包：
mysql-5.0.27.tar.gz
httpd-2.0.54.tar.gz
php-5.1.4.tar.gz HTML内嵌式的脚本语言，与微软的ASP颇有几分相似
rrdtool-1.2.13.tar.gz 一个强大的绘图的引擎
cacti-0.8.7a.tar.gz 使用rrdtool绘图
放到/home/tools/下
安装步骤:
创建cacti目录
# mkdir /usr/local/cacti
# cd /home/tools
系统默认编码为utf-8汉字会出现乱码，需要vi /etc/sysconfig/i18n文件内容，例：
LANG="zh_CN.GBK"
SUPPORTED="zh_CN.GBK:zh:zh_CN.GB2312:zh:zh_CN.UTF-8:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"
基本安装环境的配置。（apache+php+mysql）
一．mysql的安装
# tar -zxvf mysql-5.0.27.tar.gz
# cd mysql-5.0.27
# ./configure --prefix=/usr/local/cacti/mysql5027 --without-innodb --datadir=/var/lib --sysconfdir=/etc
# make && make install
初始化数据库，在安装包目录下运行：
# cp support-files/my-medium.cnf /etc/my.cnf
# ./scripts/mysql_install_db
# chown -R mysql.mysql /usr/local/cacti/mysql5027/var
二．httpd-2.0.54的安装
# tar zxvf httpd-2.0.54.tar.gz
# cd httpd-2.0.54
#./configure --prefix=/usr/local/cacti/apache2054 --enable-so --enable-rewrite --enable-vhost-alias --enable-deflate --enable-expires --enable-mime-magic --enable-cgid --enable-info
# make && make install
简单配置deflate mod设置：
# vi /usr/local/cacti/apache2054/conf/httpd.conf
加入：AddType application/x-gzip .gz .tgz 836行
AddType application/x-httpd-php .php
将 DirectoryIndex index.html index.html.var更改为: 398行
DirectoryIndex index.shtm index.shtml index.jsp index.php
将 DocumentRoot "/usr/local/cacti/apache2054/htdocs" 307行
DocumentRoot "/usr/local/cacti/cacti-0.8.7a/"
加入：LoadModule php5_module modules/libphp5.so
三．安装php5.1.14
# tar zxvf php-5.1.4.tar.gz
# cd php-5.1.4
#./configure --prefix=/usr/local/cacti/php514 --with-apxs2=/usr/local/cacti/apache2054/bin/apxs --with-apache2=/usr/local/cacti/apache2054 --with-png --with-bz2 --with-zlib --with-gd --with-kerberos --with-gettext --enable-force-cgi-redirect --with-iconv --enable-gd-native-ttf --enable-sockets --with-config-file-path=/usr/local/cacti/php514/lib --with-mysql=/usr/local/cacti/mysql5027
# make clean
# make && make install
# libtool --finish /home/tools/php-5.1.4/libs(在php源码包的目录下执行)
# cp php.ini-dist /usr/local/cacti/php514/lib/php.ini
# vi /usr/local/cacti/php514/lib/php.ini
加入：
memory_limit = 50M
display_errors = Off
log_errors = Off
log_errors_max_len = 10240
error_log = /Data/logs
post_max_size = 30M
upload_max_filesize = 50M
注：可选安装mod
安装modsecurity（mod_security 可以加强apache的安全性特别是在防sql 注入上。
# tar zxvf modsecurity-apache_2.1.0-rc4.tar.gz
# cd modsecurity-apache_2.1.0-rc4/apache2
# /usr/local/cacti/apache2054/bin/apxs -cia mod_security.c
四．安装rrdtool
安装Rrdtool前请安装以下包
安装libart
# tar zxvf libart_lgpl-2.3.17.tar.gz
# cd libart_lgpl-2.3.17
# ./configure
# make && make install
安装 cgilib
# tar zxvf cgilib-0.5.1.tar.gz
# cd cgilib-0.5.1
#./configure
# make && make install
# cd libcgi
# cp libcgi.la /usr/local/lib
# cp cgi.h /usr/include
安装 libpng
# tar zxvf libpng-1.2.10.tar.gz
# cd libpng-1.2.10
#./configure
# make && make install
安装freetype
# tar zxvf freetype-2.1.10.tar.gz
# cd freetype-2.1.10
#./configure
# make && make install
# cd /usr/include
# ln -sf /Data/include
安装 rrdtool
# tar zxvf rrdtool-1.2.13.tar.gz
# cd rrdtool-1.2.13
#./configure --prefix=/usr/local/cacti/rrdtool-1.2.13 --disable-tcl --disable-python
# make && make install
五．修改net-snmp配置文件
# vi /etc/snmp/snmpd.conf
修改如下两行
com2sec notConfigUser 172.20.57.139 example 41行
access notConfigGroup "" any noauth exact all none none 62行
去掉下面几行前面的“#”
com2sec local localhost COMMUNITY 74行
com2sec mynetwork NETWORK/24 COMMUNITY 75行
group MyRWGroup any local 78行
group MyROGroup any mynetwork 79行
view all included .1 80 85行
view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc 89行
access MyROGroup "" any noauth 0 all none none 93行
access MyRWGroup "" any noauth 0 all all all 94行
启动snmpd：
# service snmpd start
六、安装、配置cacti
# tar zxvf cacti-0.8.7a.tar.gz
# mv cacti-0.8.7a /usr/local/cacti/
# cd /usr/local/cacti/cacti-0.8.7a/
# chmod -R 777 rra log rra：图 log：日志
创建并导入cacti库,并授权
# cd /usr/local/cacti/mysql5027/bin
# ./mysqladmin -u root password '123456'
# ./mysqld_safe -umysql &
mysql> create database cacti;
mysql> \q
# cd /usr/local/cacti/cacti-0.8.7a/
# mysql cacti<cacti.sql
# ./ mysqld_safe –umysql &
# mysql> grant all on *.* to root@'%' identified by '123456';
# mysql> flush privileges;
修改cacti配置文件、连接MYSQL
#vi /usr/local/cacti/cacti-0.8.7a/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "xxx";
$database_password = "xxx";
启动apache :
# cd /usr/local/cacti/apache2054/bin/
# ./apachectl start
定时运行cacti采集数据
#/etc/crontab -e
添加一行：
*/5 * * * * /usr/local/cacti/php514/bin/php /usr/local/cacti/cacti/poller.php >/dev/null 2>&1
测试
# /usr/local/cacti/php514/bin/php /usr/local/cacti/cacti-0.8.7a/poller.php
# snmpwalk -c husong -v 1 172.20.57.139
七、初始安装next----new install—配置路径请修改：RRDTool Binary Path：/usr/local/cacti/rrdtool-1.2.13/bin/rrdtool
检查其他的默认路径，确定OK后登陆
注：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。
添加启动脚本
echo "cd /usr/local/cacti/apache2/bin;./apachectl start">>/etc/rc.local
echo "cd /usr/local/cacti/mysql/bin;./mysqld_safe & ">>/etc/rc.local |
