2、yum安装必要的软件包：
yum -y install httpd php php-mysql mysql mysql-server mysql-devel php-snmp net-snmp-utils rrdtool rrdtool-devel rrdtool-php
service mysqld start
chkconfig mysqld on
service httpd start
chkconfig httpd on
修改mysql root密码：
mysqladmin -uroot password '123456'
3、安装cacti：
yum -y install php-devel php-common net-snmp net-snmp-utils \
zlib libpng freetype libjpeg fontconfig gd libxml2 patch wget rrdtool xinetd \
gd gd-devel openssl-devel
cd /usr/local/src/cacti
tar zxvf cacti-0.8.8b.tar.gz
cp cacti-0.8.8b/* /var/www/html -R
chown -R apache:apache /var/www/html/
启动mysql为cacti创建数据库和用户
service mysqld start
mysql -uroot -p
Enter password: #密码为空
mysql> create database cacti;
mysql> grant all privileges on cacti.* to [email protected] identified by 'cacti123';
mysql> flush privileges;
导入cacti的数据库：
mysql -ucacti -pcacti123 cacti < /var/www/html/cacti.sql
修改cacti的配置文件并保存
vi /var/www/html/include/config.php
/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti123";
$database_port = "3306";
vi /var/www/html/include/global.php
/* Default database settings*/
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti123";
$database_port = "3306";
$database_ssl = false;
设置crontab定时任务:
chkconfig snmpd on
chkconfig httpd on
chkconfig mysqld on
chkconfig crond on
service httpd restart
service snmpd restart
service mysqld restart
service crond restart
web页完成安装
http://xxx.xxx.xxx.xxx
Next >> Next >> Finish
用户名和密码为：admin/admin，之后输入新的密码，就完成了最基本的安装。
开启插件管理：在cacti 页面点console–>User Management->admin->在Plugin Management上打钩->Save
sed -i 's/^;date.timezone =/date.timezone =PRC/g' /etc/php.ini
service httpd restart
crontab -e #增加如下计划任务
*/5 * * * * php /var/www/html/poller.php > /dev/null 2>&1
安装Linux系统下snmp服务
确保本机已经安装了snmp服务
# rpm -qa |grep snmp
net-snmp-libs-5.1.2-11.EL4.7
net-snmp-5.1.2-11.EL4.7
#yum -y install net-snmp*
snmpd.conf文件配置
按照如下方式修改snmpd.conf文件
A、修改默认的community string
com2sec notConfigUser default public
将public修改为你才知道的字符串
B、把下面的#号去掉
#view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
C、把下面的语句
access notConfigGroup "" any noauth exact systemview none none
改成：
access notConfigGroup "" any noauth exact mib2 none none
重启snmpd服务
#service snmpd restart
完成snmpd的配置
#chkconfig snmpd on

eof
导入配置文件：
（1）通过手工编辑的配置文件导入方法：
拷贝老的备份文件到 /usr/local/nagios/etc/nagiosql/import/ 目录
登录http://ip/nagiosql -->管理-->域-->localhost点修改-->修改为自己的目录后点保存,应该显示数据成功写入数据库。-->
工具-->导入数据，选择要导入的配置文件，点导入按钮-->nagios控制-->写入检测数据-->写入其他数据-->检查配置文件-->检查通过后，重新启动Nagios-->结束
（2）通过nagiosql生成的配置文件导入方法：
如果是导入以前的nagiosql管理的配置文件，可以备份以前的nagiosql的数据库（默认数据库名是db_nagiosql_v3），然后覆盖新nagiosql的数据，在登录web管理页面
执行工具-->导入数据，选择要导入的配置文件，点导入按钮-->nagios控制-->写入检测数据-->写入其他数据-->检查配置文件-->检查通过后，重新启动Nagios-->结束
