groupadd mysql
useradd -g mysql mysql
scripts/mysql_install_db
chown -R root /usr/local/mysql
chown -R mysql /usr/local/mysql/var
chgrp -R mysql /usr/local/mysql
rm -f /etc/my.cnf
cp support-files/my-medium.cnf /etc/my.cnf
echo /usr/local/mysql/lib/mysql >> /etc/ld.so.conf

echo
cd /etc/rc3.d/
ln -s ../init.d/mysql S85mysql
ln -s ../init.d/mysql K85mysql
cd /etc/rc5.d/
ln -s ../init.d/mysql S85mysql
ln -s ../init.d/mysql K85mysql
cd /etc/init.d/
chmod 755 mysql

2、apache的安装

cd /cacti-install
tar -zxvf httpd*
cd httpd*
./configure --prefix=/www --enable-so
make
make install
cd /www/bin
cp apachectl /etc/init.d/httpd
y
cd /etc/rc3.d/
ln -s ../init.d/mysql S85mysql
ln -s ../init.d/mysql K85mysql
cd /etc/rc5.d/
ln -s ../init.d/mysql S85mysql
ln -s ../init.d/mysql K85mysql
/www/bin/apachectl start

3、php的安装

cd /cacti-install
tar -zxvf php*
cd php*
./configure --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config-file-path=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlib-dir=/usr/include --with-gd
make
make install
cp php.ini-dist /www/php/php.ini
cp /www/conf/httpd.conf /www/conf/httpd.conf.backup
echo ####################### >> /www/conf/httpd.conf
echo # Added via Lee Carter's Script >> /www/conf/httpd.conf
echo ####################### >> /www/conf/httpd.conf
echo AddType application/x-tar .tgz >> /www/conf/httpd.conf
echo AddType application/x-httpd-php .php >> /www/conf/httpd.conf
echo AddType image/x-icon .ico >> /www/conf/httpd.conf
echo DirectoryIndex index.php index.html index.html.var >> /www/conf/httpd.conf
service httpd stop
service httpd start

4、mysql的设置

cd /cacti-install
groupadd cacti
useradd -g cacti cactiuser
/usr/local/mysql/bin/mysql
mysql> set password for root@localhost=password('rootpw');
mysql> create database cactidb;
mysql> grant all on cactidb.* to root;
mysql> grant all on cactidb.* to root@localhost;
mysql> grant all on cactidb.* to cactiuser;
mysql> grant all on cactidb.* to cactiuser@localhost;
mysql> set password for cactiuser@localhost=password('cactipw');
mysql> exit

5、rrdtool的安装

cd /cacti-install
tar -zxvf rrdtool*
cd rrdtool*
./configure --prefix=/usr/local/rrdtool
make
make install

6、net-snmp的安装

cd /cacti-install
tar -zxvf net-snmp*
cd net-snmp*
./configure
注：configure这一步过程中会要求输入一些数值，参数如下：
Setup Menu:
Default Version of SNMP (3): 1
System Contact Information (root@): New Cacti User
System Location (Unknown): Data Center Rack 2A1
Location to write logfile (/var/log/snmpd.log):
Location to write presistant information (/var/net-snmp):

make
make install

7、cacti的安装

cd /cacti-install
cp cacti* /www/htdocs/
cd /www/htdocs/
tar -zxvf cacti*
mv cacti-0.8.6b cacti/
cd cacti
/usr/local/mysql/bin/mysql --user=root --password=rootpw cactidb < cacti.sql
chown -R cactiuser rra/ log/


8、编辑/www/htdocs/cacti/include/config.php

把config.php中相应的值改成：
$database_defaut = “cactidb”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “cactipw”;

9、编辑/etc/crontab

在文件的最后一行加入：
*/5 * * * * cactiuser /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1
