Cacti安裝高效輪詢器spine

Cacti默認輪詢器cmd.php執行效率有點低，spine爲C語言編寫的組件，性能要好許多。

編譯安裝spine需如下軟件支持：

1 net-snmp-devel
2 mysql
3 mysql-devel
4 openssl-devel
5 gcc

安裝spine要和Cacti的版本相匹配，本文以最新版cacti0.8.8b安裝爲例。

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

編譯：

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
填寫數據庫信息，即Cacti數據庫。

DB_Host  localhost
DB_Database  cacti
DB_User  root
DB_Pass  cacti
DB_Port  3306

設置spine路徑，Console——Settings——Paths

更改cacti輪詢器爲spine，Console——Settings——Poller
cacti更改輪詢器爲spine

運行：

# /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

說明：spine默認配置文件須要放在/etc纔會生效，不然報以下錯誤： SPINE: Poller[0] FATAL: Unable to read configuration file! (Spine init)
