Cacti implementation on CentOS AMI

In this article I will show you some graphing solution through RRD tool along with Cacti.I can tell you it require lot of work to get thing going with Cacti for graphing.

So here we go:

For cacti installation on RHEL or CentOS we need below package to be installed in the system:

httpd
php
php-mysql
php-snmp
php-ldap (when using LDAP authentication)
php-xml
mysql
mysql-server
net-snmp (depending on the distro, net-snmp-utils may be required)


Step 1:

Fetch cacti from cacti.net

[bhaskar@Amazon-instances ~]$ wget -c http://www.cacti.net/downloads/cacti-0.8.7g.tar.gz
-2011-04-29 02:18:20- http://www.cacti.net/downloads/cacti-0.8.7g.tar.gz
Resolving www.cacti.net... 140.211.167.231, 173.225.179.10, 209.242.232.5
Connecting to www.cacti.net... connected.
HTTP request sent, awaiting response... 200 OK
Length: 2236916 (2.1M) [application/x-gzip]
Saving to: `cacti-0.8.7g.tar.gz'

2011-04-29 02:18:22 (1.34 MB/s) - `cacti-0.8.7g.tar.gz' saved [2236916/2236916]


Step 2:

Get the required software in the box:

[bhaskar@Amazon-instances ~]$ sudo yum install httpd php php-mysql php-snmp php-xml mysql mysql-server net-snmp

php-common.x86_64 0:5.2.4-RightScale php-pdo.x86_64 0:5.2.4-RightScale

Complete!

Step 3:
Now unzipping the tarball we downloaded from the cacti site:

[bhaskar@Amazon-instances ~]$ tar -xvzf cacti-0.8.7g.tar.gz

[bhaskar@Amazon-instances ~]$ ls
cacti-0.8.7g cacti-0.8.7g.tar.gz


Step 4:

Move the cacti dir to short and convinient name

[bhaskar@Amazon-instances ~]$ mv cacti-0.8.7g cacti

[bhaskar@Amazon-instances ~]$ ls
cacti cacti-0.8.7g.tar.gz


Step 5:

Now move the cacti dir to the document root of the system:

[bhaskar@Amazon-instances ~]$ sudo mv -v cacti /var/www/html/
`cacti' -> `/var/www/html/cacti'


Step 6:

Addming Cacti group and user in the box:

[bhaskar@Amazon-instances ~]$ sudo /usr/sbin/groupadd cacti

Adding users for cacti:

[bhaskar@Amazon-instances ~]$ sudo /usr/sbin/useradd -g cacti amazoncacti

Adding password to the user:

[bhaskar@Amazon-instances ~]$ sudo /usr/bin/passwd amazoncacti
Changing password for user amazoncacti.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.



Step 7:

Chnage the ownership of few dir in the cacti base dir:

[bhaskar@Amazon-instances cacti]$ sudo /bin/chown -R amazoncacti rra/ log/

[bhaskar@Amazon-instances cacti]$ ls -ld rra log
drwxr-xr-x 2 amazoncacti bhaskar 4096 Dec 30 2009 log
drwxr-xr-x 2 amazoncacti bhaskar 4096 May 16 2010 rra


Step 8:

MySql admin password creation:

[bhaskar@Amazon-instances cacti]$ sudo /usr/bin/mysqladmin -u root password somethingsensible

Step 9:

Create Cacti database for use:

[bhaskar@Amazon-instances cacti]$ sudo /usr/bin/mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.0.77 Source distribution

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

mysql> create database cacti;
Query OK, 1 row affected (0.00 sec)


Step 10:

Sourcing the default sql file into cacti database like below:

mysql> source cacti.sql

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec)

Query OK, 1 row affected (0.00 sec

output snipped for the sake of bravity!!!

Step 11:

Now time to grant some priviledge to the cacti user to get into the database and fetch thing from it. From the mysql shell do follow:

mysql> GRANT ALL ON cacti.* TO amazoncacti@localhost IDENTIFIED BY 'somethingsensible';
Query OK, 0 rows affected (0.00 sec)

Refreshing the grant table:

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


Step 12:

Now time for edit some files within cacti directory..

[bhaskar@Amazon-instances cacti]$ sudo vim include/config.php

Here it looks like inside... and I have change the database username and password entry in it:

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "amazoncacti";
$database_password = "somethingsensible";
$database_port = "3306";



Step 13:

I am creating a cron job to polls for the infomration:

[root@Amazon-instances cacti]# crontab -e

[root@Amazon-instances cacti]# crontab -l
*/5 * * * * amazoncacti /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1


Step 14:

Some php tweaking for the betterment:

[root@Amazon-instances cacti]# sudo vim /etc/php.ini

In this file I have changed memory_limit variable 32M to 128M

Step 15:

Now we need to got to the web interface of it,by pressing the following url into the browser:

http://Amazon-instances.amazonaws.com/cacti/

Step 16:

Snmpwalk not found by the cacti installer so go ahead and installed more binaries:

Step 16:

So once the web interface installed the thing we are presented the login page into with default admin/admin username/password .Now I have change that password to like below:

username : admin

password : admin

Step 17:

Adding amazoncacti user to apache group:

[bhaskar@Amazon-instances ~]$ sudo /usr/sbin/usermod -G apache -a amazoncacti
[bhaskar@Amazon-instances ~]$ id amazoncacti
uid=503(amazoncacti) gid=503(cacti) groups=48(apache),503(cacti)


Step 18:

Installing new crontab for user amazoncacti for run the poller.php

[root@Amazon-instances html]# sudo su - amazoncacti
[amazoncacti@Amazon-instances ~]$ crontab -e
no crontab for amazoncacti - using an empty one
crontab: installing new crontab


Step 19:

Step 26:

patching the cacti installation dir for PIA

Upon dry run we get this:

[bhaskar@Amazon-instances cacti]$ sudo patch -p1 -N --dry-run < /home/bhaskar/cacti-plugin-arch/cacti-plugin-0.8.7g-PA-v2.8.diff
patching file auth_changepassword.php

patching file lib/rrd.php
patching file lib/variables.php
patching file plugins/index.php
patching file plugins.php
patching file poller.php
patching file user_admin.php
patching file utilities.php

Step 26:

problem.....we need to get those two file from old location if we go ahed and do the patching

let's go:

[bhaskar@Amazon-instances cacti.orig]$ sudo cp -pv include/top_header.php /var/www/html/cacti/include/
`include/top_header.php' -> `/var/www/html/cacti/include/top_header.php'

[bhaskar@Amazon-instances cacti.orig]$ sudo cp -pv auth_login.php /var/www/html/cacti/
`auth_login.php' -> `/var/www/html/cacti/auth_login.php'


So failed patched files are copied back to modified dir.

Step 27:

Applying patched for PIA in the database

[bhaskar@Amazon-instances cacti-plugin-arch]$ sudo mysql -u amazoncacti -p
Enter password:

Step 28:

Downloading plug ins

[bhaskar@Amazon-instances ~]$ wget -c http://cactiusers.org/downloads/discovery.gzip

2011-05-04 04:58:21 (219 KB/s) - `discovery-0.8.5.tar.gz' saved [30377/30377]


Step 29:

Unzip it

[bhaskar@Amazon-instances ~]$ tar -xvzf discovery-0.8.5.tar.gz
discovery/README
discovery/index.php
discovery/discover.sql
discovery/setup.php
discovery/discover_template.php
discovery/findhosts.php
discovery/discover.php
discovery/images/index.php
discovery/images/tab_discover.gif
discovery/config.php
discovery/LICENSE

Step 30:

move the plug in dir to cacti's plugin dir

[bhaskar@Amazon-instances ~]$ sudo mv -v discovery /var/www/html/cacti/plugins/
`discovery' -> `/var/www/html/cacti/plugins/discovery'


Step 31:

Activate the plug in:

put a line like this in /var/www/html/cacti/include/config.php

$plugins[] = 'discovery';

### For every extra downloaded plug in we need to put up a line like this.

Now time for some graph..disk usage:




Here is another one memory usage:




Here one for the cpu usage;





Here something for eth0 and processes;





Hope this will help. Cacti is certainly not the easiest graphing solutions..but very cool to have one.

Cheers!
Bhaskar
