Cacti安装高效轮询器spine(转)
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：
1 net-snmp-devel
2 mysql
3 mysql-devel
4 openssl-devel
5 gcc
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。
1 cd /usr/local/src/
2 wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8a.tar.gz
3 tar -zxvf cacti-spine-0.8.8a.tar.gz
4 cd cacti-spine-0.8.8a
编译：
5 ./configure
6 make && make instatll
配置spine：
1 cd /usr/local/spine/etc/
2 mv spine.conf.dist/etc/spine.conf
3 vi 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 cacti
DB_Port 3306
设置spine路径，Console——Settings——Paths
cacti设置spine路径
/usr/local/spine/bin/spine
更改cacti轮询器为spine，Console——Settings——Poller
cacti更改轮询器为spine
运行：
#/usr/local/spine/bin/spine
SPINE: Using spine config file
SPINE: Version 0.8.7g starting
SPINE: Time: 0.2410 s, Threads: 5, Hosts: 2
说明：spine默认配置文件需要放在/etc才会生效，否则报如下错误：
SPINE: Poller FATAL: Unable to read configuration file! (Spine init)
