Cacti是一个开源的绘图和网络监控工具，用作行业标准的数据记录和RRD工具。本文介绍在Ubuntu 20.04 Linux系统上安装Cacti Spine轮询器的方法。现在，Cacti和Spine已经包含在许多Linux发行版中，所以安装它们很容易。在安装前，系统中要有Cacti。

安装Cacti Spine轮询器的步骤

步骤1、在Ubuntu 20.04上下载Cacti Spine轮询器

使用以下命令：

sudo apt install <cacti-spine-package>

但这种方法的唯一问题是，不能保证您使用最新版本的Spine。

从官方Cacti下载页面下载最新版本的Spine，地址在https://files.cacti.net/spine/。或者使用Wget下载最新版本的Cacti-spine：

sudo apt install wget

wget https://www.cacti.net/downloads/spine/cacti-spine-latest.tar.gz

步骤2、在Ubuntu 20.04上安装Cacti Spine轮询器

一旦下载，我们就可以安装它了。对于本文，我们将从源代码构建它。因此，我们将安装以下所需的软件包：

sudo apt install build-essential autoconf automake dos2unix gzip help2man m4 make wget libtool libsnmp-dev libmariadb-dev libmariadbclient-dev

提取下载的Cacti-spine文件：

tar zxvf cacti-spine-latest.tar.gz

导航到提取的文件目录：

cd cacti-spine-*/

现在，通过运行引导文件创建配置脚本，如下所示：

sudo ./bootstrap

样本输出：

INFO: Removing cache directories

INFO: Running auto-tools to verify buildability

  To compile and install Spine using MySQL versions previous to 5.5

  please do the following:

  ./configure --with-reentrant

  make

  make install

  chown root:root /usr/local/spine/bin/spine

  chmod +s /usr/local/spine/bin/spine

现在运行configure脚本来检测以下可用内容：

sudo ./configure

使用以下命令将Cacti spine安装到默认的/usr/local/spine目录中：

sudo make

sudo make install

样本输出：

make[1]: Entering directory '/home/thor/cacti-spine-1.2.19'

 /usr/bin/mkdir -p '/usr/local/spine/bin'

  /bin/bash ./libtool   --mode=install /usr/bin/install -c spine '/usr/local/spine/bin'

libtool: install: /usr/bin/install -c spine /usr/local/spine/bin/spine

 /usr/bin/mkdir -p '/usr/local/spine/etc'

 /usr/bin/install -c -m 644 spine.conf.dist '/usr/local/spine/etc'

 /usr/bin/mkdir -p '/usr/local/spine/share/man/man1'

 /usr/bin/install -c -m 644 spine.1 '/usr/local/spine/share/man/man1'

make[1]: Leaving directory '/home/thor/cacti-spine-1.2.19'

将二进制文件的所有权分配给root，如下所示：

sudo chown root:root /usr/local/spine/bin/spine 

sudo chmod +s /usr/local/spine/bin/spine

创建Spine配置文件：

sudo cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf

编辑配置文件并添加数据库详细信息：

sudo vi /usr/local/spine/etc/spine.conf

在文件中，添加数据库详细信息，如下所示：

DB_Host 'localhost'

DB_Database 'cacti'

DB_User 'cacti_user'

DB_Pass 'strongpassword'

DB_Port '3306'

步骤3、使用Cacti Spine轮询器

登录到您的Cacti站点并导航到Configuration->Settings：

现在更新您的Cacti配置如下：

Spine Binary File Location : /usr/local/spine/bin/spine

Spine Config File Path : /usr/local/spine/etc/spine.conf

在路径下，应按以下方式填充：

保存所做的更改并将Poller更新为Cacti-spine，如图所示：

现在，使轮询器能够从受监控的设备收集数据，添加一个新的crontab，以便能够通过SNMP查询设备：

sudo crontab -u www-data -e

选择所需的编辑器并继续将以下行添加到文件中：

*/5 * * * * /usr/bin/php /var/www/html/poller.php

给它几分钟时间，然后在图形->默认树（Graphs -> Default Tree）下进行检查。您应该能够看到收集的数据，如下所示：

至此，已经成功的在Ubuntu 20.04上安装了Cacti Spine轮询器。
