HowTo: Cacti 0.8.7g + Plugin Architecture 2.9 + Spine 0.8.7g on CentOS 5.5 i386

Cacti is a web application that will help you monitor the status of your server, CISCO and everything that can send data via the SNMP protocol. You can monitor the server CPU load, see on the chart the average memory load for a period of time, the number of DNS requests coming to the server, the number of letters (spam) coming to the mail server. You can monitor the average load on the network during working hours and much more.



Cacti Plugin Architecture is an add-on for Cacti that extends the capabilities of the standard package by incorporating the installation of third-party plug-ins.



Spine is a fast and high quality poller for Cacti written in C. It is used instead of the standard poller coming in the standard Cacti installation, cmd.php.

Indicative, basic installation Cacti with pribombasy CentOS 5.5 i386. Many elements of the web server security settings are ignored due to the test installation. All actions will be performed under the root.



Let's start with the installation of the LAMP basic web server.



Install the RPMforge repository:

rpm -Uhv apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm



Update the system and reboot:

yum -y update

reboot



Install the standard packages for the web server:

yum install -y mysql mysql-server mysql-devel httpd httpd-devel php php-mysql php-gd phpimap

php-ldap php-odbc php-pear php-xml php-xmlrpc php-mcrypt curl curl-devel perl-libwwwperl

libxml2 php-mbstring phpmyadmin



Setting up MySQL server:

chkconfig mysqld on

service mysqld start

mysql_secure_installation



Enter the last command, carefully read and follow the points of its output. In the end, you will have to set a password for MySQL root, allow external connections to the server, disable anonymous user, remove the test database, update the server records.



Apache configuration, httpd:

chkconfig httpd on

service httpd start





Setting up phpMyAdmin:

vim /etc/httpd/conf.d/phpmyadmin.conf



#

# Web application to manage MySQL

#

#<Directory "/usr/share/phpmyadmin">

# Order Deny,Allow

# Deny from all

# Allow from 127.0.0.1

#

Alias ​​/ phpmyadmin / usr / share / phpmyadmin

Alias ​​/ phpMyAdmin / usr / share / phpmyadmin

Alias ​​/ mysqladmin / usr / share / phpmyadmin



vim /usr/share/phpmyadmin/config.inc.php



Find the following line (in my case it is 17th):

$cfg['blowfish_secret'] = '';



Follow this link and copy the generated secret blowfish. Insert it at the end, between single quotes. Example:

$cfg['blowfish_secret'] = '85NoZZ8_y})SzG5{ys1_#YEQoxwC*sn02%JhcK@WA';



Restart httpd:

service httpd restart





Let's start the installation of Cacti itself.



Install the dependencies needed by Cacti:

yum install -y net-snmp net-snmp-utils rrdtool php-snmp



Add to autoload and run SNMP service:

chkconfig snmpd on

service snmpd start



Download Cacti Packages:

wget www.cacti.net/downloads/cacti-0.8.7g.tar.gz

wget www.cacti.net/downloads/pia/cacti-plugin-0.8.7g-PA-v2.9.tar.gz

wget www.cacti.net/downloads/spine/cacti-spine-0.8.7g.tar.gz



Unzip them:

tar -xzvf cacti-0.8.7g.tar.gz

tar -xzvf cacti-plugin-0.8.7g-PA-v2.9.tar.gz

tar -xzvf cacti-spine-0.8.7g.tar.gz



Create a working Cacti folder on the server:

mkdir /var/www/cacti



Copy the contents of the unpacked folder Cacti to the working folder Cacti:

cp -rf cacti-0.8.7g/* /var/www/cacti/



Create a user system for Cacti and give it the appropriate rights:

useradd -c CactiUser -d /var/www/cacti/ -s /sbin/nologin cactiuser

chown -R root /var/www/cacti ( Cacti )

chown -R cactiuser /var/www/cacti/log /var/www/cacti/rra



Create a database for Cacti with privileges for cactiuser:

mysql -u root -p

Enter password:



Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 55

Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.



mysql> create database cacti;

mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipassword';

mysql> flush privileges;

mysql> quit



Import the Cacti structure into its base:

mysql -u cactiuser -p cacti < /var/www/cacti/cacti.sql

Enter password: (cactipassword)



Set up Cacti's access to its database:

vim /var/www/cacti/include/config.php



$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactipassword";

$database_port = "3306";



Go to the working directory of Cacti and fix the fixes with official patches:

cd /var/www/cacti



wget www.cacti.net/downloads/patches/0.8.7g/data_source_deactivate.patch

wget www.cacti.net/downloads/patches/0.8.7g/graph_list_view.patch

wget www.cacti.net/downloads/patches/0.8.7g/html_output.patch

wget www.cacti.net/downloads/patches/0.8.7g/ldap_group_authenication.patch

wget www.cacti.net/downloads/patches/0.8.7g/script_server_command_line_parse.patch

wget www.cacti.net/downloads/patches/0.8.7g/ping.patch

wget www.cacti.net/downloads/patches/0.8.7g/poller_interval.patch

patch -p1 -N < data_source_deactivate.patch

patch -p1 -N < graph_list_view.patch

patch -p1 -N < html_output.patch

patch -p1 -N < ldap_group_authenication.patch

patch -p1 -N < script_server_command_line_parse.patch

patch -p1 -N < ping.patch

patch -p1 -N < poller_interval.patch



Back in the home directory:

cd



Create cacti.conf to enable web access:

vim /etc/httpd/conf.d/cacti.conf



Alias /cacti /var/www/cacti

<Directory /var/www/cacti/>

DirectoryIndex index.php

Options -Indexes

AllowOverride all

order deny,allow

deny from all

allow from 192.168.1.0/24 (you can do it like "allow from all")

AddType application/x-httpd-php .php

php_flag magic_quotes_gpc on

php_flag track_vars on





Restart Apache:

service httpd restart



Create a cron task for Cacti:

vim /etc/cron.d/cacti

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



From this point on, you can start using the basic Cacti installation in production, but let's install additional, not unnecessary functionality.



Cacti Plugin Architecture.



Copy the .diff patch architecture file to the Cacti working directory:

cp cacti-plugin-arch/cacti-plugin-0.8.7g-PA-v2.9.diff /var/www/cacti/



Go to the working folder Cacti and perform a test patch application, in order to see if there is any interference:

cd /var/www/cacti/



patch -p1 -N --dry-run < cacti-plugin-0.8.7g-PA-v2.9.diff



The test should go bang, except for one line, but this is not a problem:

patching file include / config.php

Hunk # 1 succeeded at 30 with fuzz 1.

After making sure that the patch process should not cause any problems, apply the patch itself:

patch -p1 -N < cacti-plugin-0.8.7g-PA-v2.9.diff



Edit the Cacti configuration file:

vim /var/www/cacti/include/config.php



Find the next line and be sure to enter into it the working directory of Cacti (starting with the root of the web server folder). In our case it will look like this:

$url_path = "/cacti/";



Import additional plugin architecture base schema into the Cacti database:

mysql -u cactiuser -p cacti < /root/cacti-plugin-arch/pa.sql

Enter password: (cactipassword)





Let's go to the installation of Spine.



Install the dependencies needed when compiling Spine:

yum install -y net-snmp-devel



Go to the unzipped Spine folder and start compiling:

cd /root/cacti-spine-0.8.7g

./configure --prefix=

make

make install



Rename the spine configuration file:

mv /etc/spine.conf.dist /etc/spine.conf



Let's allow spine access to the Cacti database:

vim /etc/spine.conf



DB_Host localhost

DB_Database cacti

DB_User cactiuser

DB_Pass cactipassword

DB_Port 3306

DB_PreG 0





At last we will come on a page of our Cacti server / cacti .

We will see a couple of pages of the process of "installation" cacti. Click Next twice and Finish third time.

Login to console: admin / admin



Go to the Settings page, then to the Paths tab.

At the bottom of the page, let us prescribe to the Spine binary. In our case:

/bin/spine







Then go to the tab Poller and set in the graph Poller Type - spine.





To enable Plugin Management, you need to go to the User Management page, the Realm Permissions tab and put the bird next to Plugin Management.

Persist.



And in the end let's try to put one plugin.

Go to the plugins folder in the Cacti directory:

cd /var/www/cacti/plugins



Download and unzip the plugin archive:

wget docs.cacti.net/_media/plugin:settings-v0.7-1.tgz

mv -f plugin:settings-v0.7-1.tgz settings-v0.7-1.tgz

tar -xzvf settings-v0.7-1.tgz





After these steps, go back to the Cacti management console, to the Plugin Management page.

Install and enable the plugin.



That's all.



Thank you for your attention and patience.



UPD .:

This is the standard graphics at the end of our installation. A space in the chart because I didn’t immediately make this screenshot and turned off the virtual machine. Below is a screen from the working system.
