Cacti tool configuration

Step 1:

install packages required:

yum -y install mysql-server php php-cli php-mysql net-snmp-utils rrdtool php-snmp gcc mysql-devel net-snmp-devel autoconf automake libtool dos2unix

Step 2:

make sure webserver and the database are automatically starting up after a reboot. Use the following commands to enable these:

#/etc/init.d/httpd start; chkconfig httpd on

#/etc/init.d/mysqld start; chkconfig mysqld on

#/etc/init.d/crond start; chkconfig crond on

step 3: install cacti

Download the cacti  from below command

#cd /var/www/html             #wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz                 #tar -xzvf cacti-0.8.8a.tar.gz

               

Step 4: change cacti version if it is useful :

                #ln -s cacti-0.8.8a cacti

Create the system “cacti” user now:

                #adduser cacti

Step 5:

edit cron  job for cacti , 5 minute polling interval by uncommenting the command in file /etc/cron.d/cacti

echo "*/5 * * * * cacti php /var/www/html/cacti/poller.php &>/dev/null" >> /etc/cron.d/cacti

Step 6:

 make sure that the permissions on the log and rra directories are set:

                #cd /var/www/html/cacti

                #chown -R cacti.apache rra log 

                #chmod 775 rra log

Step 7: MySQL CONFIGURATION

            #mysql -u root -p

#create database cacti;                      #GRANT ALL ON cacti.*                 #TO cacti@localhost             #IDENTIFIED BY 'techmark';             #flush privileges;              #exit Copy cacti sql dump file to new cacti database              # mysql -u cacti cacti  < cacti.sql -p

Step 8: setting the database credentials

Before going to the web-based installation set database credentials within the Cacti config file:

            #cd /var/www/html/cacti/include/

            #vi config.php

Change the $database_ lines to fit your new settings:

           

#$database_type = "mysql";             #$database_default = "root";             #$database_hostname = "localhost";             #$database_username = "root";             #$database_password = "Password";             #$database_port = "3306";             #$database_ssl = false;

at the end of the file you should also uncomment the following line in the above file

            #$url_path = "/cacti/";

Step 9: WEB –BASED INSTALLER
