cacti yum安装

1.配置好yum源、关掉selinux
# setenforce 0


2.安装所要工具组件：
# yum install httpd php php-mysql php-snmp mysql mysql-server perl-DBD-MySQL php-pdo net-snmp net-snmp-libs net-snmp-utils net-snmp-devel ruby ruby-devel


3.配置启动apache mysql snmp服务
# service httpd start
# chkconfig httpd on

# service mysqld start
# mysqladmin -u root password 'root'
# mysql -uroot -proot
mysql> use mysql
mysql> delete from user where host='';
# chkconfig mysqld on

# service snmpd start
# chkconfig snmpd on


4.安装rrdtools，需要用到rrdtool-1.4.4-1.el5.wrl.i386.rpm、rrdtool-perl-1.4.4-1.el5.wrl.i386.rpm、rrdtool-ruby-1.4.4-1.el5.wrl.i386.rpm rrdtools.zip   
# yum localinstall --nogpgcheck rrdtool-*.rpm


5.配置snmp
# vim /etc/snmp/snmp.conf
将com2sec   notConfigUser    default  public
改为 com2sec   notConfigUser   192.168.0.0/16  public //此处是修改监控目标

将access  notConfigGroup ""      any       noauth    exact   systemview none none
改为access  notConfigGroup ""      any       noauth    exact  all  systemview none none

#view  all  included  .1  80
将前面的#注释去掉。

# service snmpd restart


6.安装cacti数据库以及模板
1）配置mysql数据库
# mysql
mysql> CREATE DATABASE cacti;
mysql> grant all privileges on cacti.* to cacti@localhost identified by 'cacti';
mysql> grant all ptivileges on cacti.* to cacti@127.0.0.1 identified by 'cacti';
mysql> grant all ptivileges on cacti.* to cacti@192.168.0.0 identified by 'cacti';
mysql> flush privileges;
mysql> quit

2）安装cacti
# tar zxvf cacti-0.8.7g.tar.gz
# mv cacti-0.8.7g /var/www/html/cacti
# cd  /var/www/html/cacti
# mysql -ucacti -pcacti cacti < /var/www/html/cacti/cacti.sql
# vim /var/www/html/cacti/include/config.php
修改成：
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
# useradd cacti
# passwd cacti
# chown -R cacti  /var/www/html/cacti/rra  /var/www/html/cacti/log
# crontab -e
*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1

3）访问
第一次登陆user password 都为admin，并且需要强行修改
第一次绘图比较慢，需要一定的时间，请耐心等待
