2- Configure and Create cacti MySQL database
@ Setting mysql password for root
# mysqladmin -u root password NEWPASSWORD
@ Create cacti MySQL database
#mysql -u root -p -e 'create database cacti'# mysql -u root -pmysql> GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY 'X';mysql> FLUSH privileges;mysql> \q 3- Configure SNMP
# vim /etc/snmp/snmpd.conf
Modify the following Parameters:
com2sec local localhost public
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local
view all included .1 80
access MyRWGroup “” any noauth exact all all none
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
Next
# /etc/init.d/snmpd start ; chkconfig snmpd on
Now we will test snmp:
#snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex
The output Should be like this:
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.196.202.1.8 = INTEGER: 2
.
4- Install and configure Cacti
- Download cacti-version.tar.gz from cacti website then unpack it in /var/www/html
#tar xzvf cacti-version.tar.gz
- Import the default cacti database:
# mysql cacti < cacti.sql –p
- Create cacti user
#useradd cacti -s /sbin/nologin -d /var/www/html/cacti-0.8.7g/
- Edit include/config.php and specify the database type, name, host, user and password for your Cacti configuration:
.
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cacti”;
$database_password = “XXX”;
$database_port = “3306″;
.
@ Set the appropriate permissions on cacti’s directories for graph/log generation. You should execute these commands from inside cacti’s directory to change the permissions.
#Cd /var/www/html/cacti-version/
#Chown -R cactiuser rra/ log/
@ Add a line to your /etc/crontab file similar to: “*/5 * * * * cacti php /var/www/html/cacti-version/poller.php > /dev/null 2>&1″
.
5- Configure Apache
# vim /etc/httpd/conf.d/cacti.conf
#
# Cacti: An rrd based graphing tool
#
Alias /cacti /var/www/html/cacti-version
<Directory /var/www/html/cacti-version>
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24

#/etc/init.d/httpd restart
