折騰了十多天，把系統都重裝了，ports調整了幾個時間了，最後找到的問題是，模板要選用ucd/net snmp，我以前用Cisco Router的模板，最近不知道怎麼了，不行了，可能還是因為linux和freebsd的差異導致的。
把我的安裝過程貼一下吧，希望對大家有用。
前提的apache、php、mysql就不多說了，後面的是cacti等的操作。
安裝rrdtool
cd /usr/ports/net/rrdtool
make install clean;
安裝net-snmp
cd /usr/ports/net-mgmt/net-snmp
make install clean;
snmpd_enable="YES"
snmpd_flags="-a /var/run/snmpd.pid"
snmptrapd_enable="YES"
snmptrapd_flags="-a -p /var/run/snmptrapd.pid"
mkdir /usr/local/etc/snmp

導入數據庫
cp -R /usr/local/share/cacti /usr/
cd /usr/cacti
chown -R cacti:cacti rra/
chown -R cacti:cacti log/
cd scripts
chown cacti:cacti *
cd..
mysql -u root –p***** cacti < cacti.sql
ee /usr/cacti/include/db-settings.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "*****";
核對以上幾項是否正確
crontab -u cacti –e
