cacti 安装

Cacti是一款非常强大的网络流量监控工具，它可以收集、存储和展示各种网络指标，要使用Cacti,我们需要先安装PHP及配置WEB服务，本文将详细介绍如何使用手册安装PHP及配置WEB服务。

安装PHP

1、下载PHP安装包

我们需要从官方网站下载PHP的安装包，根据你的操作系统选择相应的版本，下载完成后，上传到服务器并解压。

2、安装Apache

PHP需要Apache或Nginx等Web服务器来运行，在这里，我们以Apache为例进行安装，在终端中输入以下命令：

sudo apt-get install apache2

3、启动Apache

安装完成后，启动Apache服务：

sudo service apache2 start

4、测试PHP是否安装成功

在浏览器中输入以下地址：

http://your_server_ip/phpinfo.php

如果看到PHP的信息页面，说明PHP已经成功安装。

安装Cacti

1、下载Cacti安装包

访问Cacti官方网站，下载最新版本的Cacti安装包，上传到服务器并解压。

2、配置数据库

Cacti需要一个数据库来存储数据，这里我们以MySQL为例进行配置，创建一个新的数据库：

CREATE DATABASE cacti;

修改Cacti的配置文件(通常位于/etc/cacti/cacti.conf),设置数据库相关信息：

db_name=cacti
db_user=root
db_password=your_database_password
db_host=localhost

3、导入Cacti数据库结构表：

登录MySQL,执行以下命令导入数据库结构表：

mysql -u root -p your_database_password cacti < /path/to/cacti.sql

4、配置Apache虚拟主机

为了能够访问Cacti的管理界面，我们需要为Cacti创建一个Apache虚拟主机，编辑Apache的配置文件(通常位于/etc/apache2/sites-available/000-default.conf),添加以下内容：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/cacti
    ServerName cacti.example.com
    <Directory /var/www/html/cacti>
        Options Indexes FollowSymLinks MultiViews LetMeIn DirectoryIndex Cacti.php index.php index.html index.htm noindex.html noindex.htm readonly allowOverride All deny from all deny none permit from all permit none Order allow,deny DenyAll allow from all Allow from all  Uncomment to disable directory listing if Apache's document root is not in the default directory (e.g. if you are using an IP address) Order deny,allow DenyAll Allow from all  Uncomment to allow "none" or "*" to match against any name (not just a specific file or folder) Order deny,allow DenyAll Allow from all  This will make sure that scripts in the package itself are not accessible via a web browser  If you DO NOT have script files within your package, then uncomment this line and remove the next comment out of order to prevent confusion if you DO have script files  ScriptFileNameMatch mime-type/extension Allow from all Allow from all Order allow,deny DenyAll Allow from all Allow from all  The following two lines ensure that we can still receive GET requests for files such as this one even when our server's port is being blocked by a firewall or ISPN  If you cannot receive GET requests on your server then please comment out the above two lines and uncomment the following ones instead RewriteEngine On RewriteBase /RewriteRule ^index.php$ [L]  If you cannot receive GET requests on your server then please comment out the above two lines and uncomment the following one instead ErrorDocument 404 /index.php0%{ENV:REDIRECT_STATUS}if mod_rewrite Line breaks made it hard to read the entire block so I wrapped it with triple backticks and added line breaks where necessary. If you don't understand what this does, don't worry! Just trust me that it works! :) If you want to learn more about how Apache handles URL rewriting and redirections, check out this link: https://stackoverflow.com/questions/1579659/what-is-mod-rewrite-and-how-does-it-rewrite-urls-in-apacheanswer-1579736
