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

yum -y install net-snmp-devel mysql mysql-devel openssl-devel 安装spine要和cacti的版本相匹配，本文以cacti-0.8.7e-cn-utf8安装为例。

cd /usr/local/src
wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.7e.tar.gz
tar zxvf cacti-spine-0.8.7e.tar.gz 
cd cacti-spine-0.8.7e
./configure
make
make install

#### 提示：configure: error: cannot run /bin/sh config/config.sub yum -y install libtool make #### 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 设置-路径 更改cacti轮询器为spine，Console——Settings——Poller 设置-轮询器 测试spine轮询器：

/usr/local/spine/bin/spine 
SPINE: Using spine config file [spine.conf]
SPINE: Version 0.8.8a starting
SPINE: Time: 0.1167 s, Threads: 1, Hosts: 2

如出现FATAL: Unable to read configuration file! (Spine init)请确认以上配置是否正确。
