Cacti安装高效轮询器spine

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cacti0.8.8b安装为例。

1 cd /usr/local/src/
2 wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8b.tar.gz
3 tar -zxvf cacti-spine-0.8.8b.tar.gz
4 cd cacti-spine-0.8.8b

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 [/etc/spine.conf]

SPINE: Version 0.8.8b starting

SPINE: Time: 1.1542 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[0] FATAL: Unable to read configuration file! (Spine init)
