Cacti默认轮询器cmd.php执行效率有点低，spine为C语言编写的组件，性能要好许多。
编译安装spine需以下软件支持：
net-snmp-devel
mysql
mysql-devel
openssl-devel安装spine要和Cacti的版本相匹配，本文以最新版cacti0.8.8a安装为例。
cd /usr/local/src
wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8a.tar.gz
tar zxvf cacti-spine-0.8.8a.tar.gz
cd cacti-spine-0.8.8a
./configure
make
make install配置spine：
cd /usr/local/spine/etc/
mv spine.conf.dist spine.conf
vim spine.conf填写数据库信息，即Cacti数据库。
DB_Host localhost
DB_Database cacti
DB_User root
DB_Pass passwd
DB_Port 3306设置spine路径，Console——Settings——Paths
更改cacti轮询器为spine，Console——Settings——Poller
测试spine轮询器：
/usr/local/spine/bin/spine
