Cacti是一款非常強大的網(wǎng)絡(luò)流量監(jiān)控工具，它可以收集、存儲和展示各種網(wǎng)絡(luò)指標，要使用Cacti,我們需要先安裝PHP及配置WEB服務(wù)，本文將詳細介紹如何使用手冊安裝PHP及配置WEB服務(wù)。
目前創(chuàng)新互聯(lián)已為成百上千的企業(yè)提供了網(wǎng)站建設(shè)、域名、虛擬主機、網(wǎng)站托管、服務(wù)器托管、企業(yè)網(wǎng)站設(shè)計、興安網(wǎng)站維護等服務(wù)，公司將堅持客戶導向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。
安裝PHP
1、下載PHP安裝包
我們需要從官方網(wǎng)站下載PHP的安裝包，根據(jù)你的操作系統(tǒng)選擇相應(yīng)的版本，下載完成后，上傳到服務(wù)器并解壓。
2、安裝Apache
PHP需要Apache或Nginx等Web服務(wù)器來運行，在這里，我們以Apache為例進行安裝，在終端中輸入以下命令：
sudo apt-get install apache2
3、啟動Apache
安裝完成后，啟動Apache服務(wù)：
sudo service apache2 start
4、測試PHP是否安裝成功
在瀏覽器中輸入以下地址：
http://your_server_ip/phpinfo.php
如果看到PHP的信息頁面，說明PHP已經(jīng)成功安裝。
安裝Cacti
1、下載Cacti安裝包
訪問Cacti官方網(wǎng)站，下載最新版本的Cacti安裝包，上傳到服務(wù)器并解壓。
2、配置數(shù)據(jù)庫
Cacti需要一個數(shù)據(jù)庫來存儲數(shù)據(jù)，這里我們以MySQL為例進行配置，創(chuàng)建一個新的數(shù)據(jù)庫：
CREATE DATABASE cacti;
修改Cacti的配置文件(通常位于/etc/cacti/cacti.conf),設(shè)置數(shù)據(jù)庫相關(guān)信息：
db_name=cacti db_user=root db_password=your_database_password db_host=localhost
3、導入Cacti數(shù)據(jù)庫結(jié)構(gòu)表：
登錄MySQL,執(zhí)行以下命令導入數(shù)據(jù)庫結(jié)構(gòu)表：
mysql -u root -p your_database_password cacti < /path/to/cacti.sql
4、配置Apache虛擬主機
為了能夠訪問Cacti的管理界面，我們需要為Cacti創(chuàng)建一個Apache虛擬主機，編輯Apache的配置文件(通常位于/etc/apache2/sites-available/000-default.conf),添加以下內(nèi)容：
ServerAdmin webmaster@localhost DocumentRoot /var/www/html/cacti ServerName cacti.example.com 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
