安装RedHat AS 4原始系统,不要选择Web服务器的所有包,选择Mysql开头的所有包,选择开发工具上面的所有包.

安装Apache
tar -zvxf httpd-2.2.tar.gz
cd httpd-2.2
./configure --prefix=/usr/local/apache --enable-so
make
make install

安装Net-snmp
在disk 2上执行
# rpm -ivh lm_sensors-2.8.7-2.i386.rpm
在disk 2,disk 4上执行
# rpm -ivh net-snmp*
# rpm -qa | grep net-snmp
net-snmp-libs-5.1.2-11
net-snmp-perl-5.1.2-11
net-snmp-5.1.2-11
net-snmp-devel-5.1.2-11
net-snmp-utils-5.1.2-11
# vi /etc/snmp/snmpd.conf
更改 1、com2sec notConfigUser default public
改为：com2sec notConfigUser 127.0.0.1 public
2、access notConfigGroup "" any noauth exact systemview none none
改为：access notConfigGroup "" any noauth exact all none none
3、#view all included .1 80
将前面的 # 注释 去掉。
保存退出 :wq
# service snmpd restart
# service mysqld start
/usr/local/apache/bin/apachectl start
chkconfig --level 345 snmpd on
chkconfig --level 345 mysqld on

rrdtool 1.2.12 中文化 Patch , 若不懂 patch 请先研究用法
(建议手动修改源代码)
新版的 rrd (1.2.x) 调用 FT (freetype2) 做 TTF 输出
所以程序用 1.0.x 版完全不能适用哦,切记

打完补丁后,继续
cd /tmp/rrdbuild/rrdtool-1.2.12/rrdtool-1.2.12
./configure --prefix=$INSTALL_DIR --disable-python --disable-tcl
make clean
make
make install

PHP:
cd $BUILD_DIR
wget
tar zxvf php-5.1.2.tar.gz
cd php-5.1.2

make
make install
cp ./php.ini-dist /usr/local/lib/php.ini

修改httpd.conf
#vi /usr/local/apache/conf/httpd.conf
加载php模块，去掉注释“＃”，如没有此行，请加上。
LoadModule php5_module modules/libphp5.so
加上此两行
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps

DirectoryIndex index.html
在后面加上 index.php
如下:
DirectoryIndex index.html index.php
重启Apache生效

Cacti:
cp cacti-0.8.6g.tar.gz /usr/local/apache/htdocs
cd /usr/local/apache/htdocs
tar zxvf cacti-0.8.6g.tar.gz
mv cacti-0.8.6g cacti
cd cacti
mysqladmin -uroot create cacti
mysql -uroot cacti < cacti.sql
创建帐号:
mysql -uroot
grant all privileges on cacti.* to cactiuser@localhost identified by 'cacti';
flush privileges;
exit
useradd cactiuser
chown –R cactiuser rra/ log/
vi ./include/config.php
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “cacti”;
vi /etc/crontab
*/5 * * * * cactiuser /usr/local/bin/php /usr/local/apache/htdocs/cacti/poller.php > /dev/null 2>&1

我们发现，如果将一个device以中文命名，会在devices页面出现乱码，而且图像也会出现乱码。为了解决这些问题，实现使用中文的目的，我们需要修改cacti和rrdtool的代码，以让其支持中文。
注意：我这里所说的“支持中文”只是让cacti能显示中文，而不是将cacti全部汉化。如果有朋友有兴趣想要为cacti的汉化出一份力的话，可以联系其作者。

软件版本：
cacti-0.8.6g
rrdtool-1.2.12
支持中文环境的linux

最后在cacti的“setting”－》“Paths”－》“RRDTool Default Font Path”中填上中文的fonts，比如：“/usr/share/fonts/zh_CN/TrueType/gbsn00lp.ttf”。

在支持中文环境的linux上能成功实现中文显示。
