#chkconfig snmpd on //开机启动
#vi /etc/snmp/snmpd.conf

com2sec local localhost public
com2sec mynetwork 192.168.0.0/24 public //设置可以远程监控主机的网段

group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
Replace with:
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
group MyROGroup v1 mynetwork
group MyROGroup v2c mynetwork
group MyROGroup usm mynetwork

syslocation RHEL6.4

#snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex //test snmp server
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.192.168.1.3 = INTEGER: 2 //这样显示则success

#/etc/init.d/mysqld start
#mysql_secure_installation //添加mysql密码
#mysqladmin -pwestos create cacti //创建cacti库
#cd /var/www/html/cacti
#mysql -pwestos cacti < cacti.sql
>grant all on cacti.* to cacti@localhost identified by 'cacti'; //添加授权用户

#vi /var/www/html/cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti"; //数据库名
$database_hostname = "localhost";
$database_username = "cacti"; //授权用户名
$database_password = "cacti"; //用户密码
$database_port = "3306";
$database_ssl = false;

$url_path = "/cacti/";
$cacti_session_name = "Cacti"; //去掉注释
#useradd cacti
#chown -R cacti /var/www/html/cacti-0.8.8b/
切换至cacti用户：
#crontab -e
*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1
//将标准输出和标准错误输出都收入空设备文件
//1>/dev/null ：首先表示标准输出重定向到空设备文件，也就是不输出任何信息到终端，说白了就是不显示任何信息。
//2>&1 ：接着，标准错误输出重定向到标准输出，因为之前标准输出已经重定向到了空设备文件，所以标准错误输出也重定向到空设备文件。

#crontab -l //查看

使用浏览器访问192.168.1.3/cacti，初始帐号密码均为admin，进入后强制改密码
