如何在ISConfig服務器上安裝Cacti

這篇教程將指導我們怎樣一步一步地在ISPConfig服務器上安裝Cacti監測工具。從標準安裝好的ISPConfig服務器或者Apache中安裝Cacti不是件麻煩人，很容易搞定。

In this article I describe how to install and setup the Cacti in a ISPConfig Server. There aren't many differences from installing in other ISP Managers or standalone Apache installations. I tried many others solutions, but Cacti is very simple and fast to implement.

In Cacti website we find: "Cacti is a complete network graphing solution designed to harness the power of cquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices."

I use a Ubuntu Edgy Eft (6.10), and followed the The Perfect Setup - Ubuntu 6.10 Server (Edgy Eft).

I will use as an example:
-          Domain Name: monitor.domain.br
-          MySQL Database Name: web1_db1
-          MySQL Username: web1_u1
-          MySQL User Password: mysqlpassword
-          Website Sytem Folder: /var/www/web1/web/
-          Cacti Version: 0.8.6i

Step 1 - Create a website and a database:

In ISPConfig, create a website via “New site” in the main menu.

On the tab called “Basis” use monitor for the hostname and domain.br for the domain name. Enable MySQL and PHP scripts for this website but disable PHP Safe Mode.

Go to your new website, in tab "Options", In Database click in the New button to create a database web1_db1 and user web1_u1.

Step 2 - Install Cacti dependencies:

To install Cacti, the easy and fast way is use apt-get. Using user with administrative permissions, run in the shell:

sudo apt-get install cacti

The Cacti is installed now, but not the last version. In Ubuntu/Debian respository have the 0.8.6c version, and in the Cacti website has newer version, 0.8.6i.

Now, I will remove only the older Cacti version, not your dependencies:

sudo dpkg -r cacti

To enable the snmp, I will install the snmpd packet:

sudo apt-get install snmpd

Step 3 - Install the new version of Cacti:

Now, I will download Cacti to our website folder:

cd /var/www/web1/web/
sudo wget http://www.cacti.net/downloads/cacti-0.8.6i.tar.gz

Extract Cacti with the command:

sudo tar xzvf cacti-0.8.6i.tar.gz
cd cacti-0.8.6i/
sudo mv * ../
cd ../
sudo rmdir cacti-0.8.6i

Remove the tar.gz files and .htaclearcase/" target="_blank" >ccess files:

sudo rm *.tar.gz
sudo rm .htaccess
sudo rm config/.htaccess

Step 4 - Setup the Cacti database:

Create the MySQL database (If you prefer, you can use the PHPMyAdmin):

sudo mysqladmin --user=web1_u1

Import the default cacti database:

sudo mysql web1_db1 < cacti.sql

Set up database:

sudo mysql --user=web1_u1 mysql
mysql> GRANT ALL ON web_db1.* TO web1_u1@localhost IDENTIFIED BY mysqlpassword;
mysql> flush privileges;

Step 5 - Configure Crontab and Privileges:

To run every five minutes, and get your system stats, we need to add one line in Crontab:

*/5 * * * * php /var/www/cacti/poller.php > /dev/null 2>&1

Set the appropriate permissions on cacti's directories for graph/log generation.

sudo chown -R www-data:www-data rra
sudo chown -R www-data:www-data logs

Step 6 - Plugin Architecture:

The Plugin Architecture for Cacti was designed to be both simple in nature and robust enough to allow freedom to do almost anything in Cacti. Cacti itself is designed nicely enough that integrating into it is fairly easy with very little modifications necessary. Eventually Cacti will come with a standard plugin architecture that will allow you to create addons without the need to modify your installation, but until that time comes (we are working on it) you will need to follow the directions below.

sudo wget http://download.cactiusers.org/downloads/cacti-plugin-arch.gzip
sudo tar xvzf cacti-plugin-arch.tar.gz

In the Architecture extracted folder, I will replace the original files with that new files:

sudo mv cacti-plugin-arch/files-0.8.6i /var/www/web1/web

Once this is done, you will have successfully completed installing the Plugin Architecture. It enable to use many plugins developed by others users.

See this link for information about this plugins: http://cactiusers.org/wiki/Homepage.

Step 7 - Configure Cacti:

In the same folder (/var/www/web1/web/):

editor include/config.php

Edit include/config.php and specify the MySQL user, password and database for your Cacti configuration.

$database_default = "web1_db1";
$database_hostname = "localhost";
$database_username = "web1_u1";
$database_password = "mysqlpassword";

Step 8 - First Access:

Go to http://monitor.domain.br, the login page will show.

Log in the with a username/password of admin. You will be required to change this password immediately. Make sure to fill in all of the path variables carefully and correctly on the following screen.
