Cacti is a popular network graphing tool that allows you to monitor and graph various metrics about your network devices. Here’s how to install and configure Cacti on RedHat and CentOS:<\/p>\n

    \n
  1. Install the necessary packages using the yum<\/code> package manager:\n
    \n
    <\/div>\n
    sudo yum install cacti cacti-spine httpd mariadb-server php php-mysqlnd net-snmp net-snmp-utils php-snmp -y
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  2. Start the mariadb<\/code> service and configure it to start automatically on boot:\n
    \n
    <\/div>\n
    sudo systemctl start mariadb
    \nsudo systemctl enable<\/span> mariadb
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  3. Run the mysql_secure_installation<\/code> script to secure the MariaDB installation and set the root password:\n
    \n
    <\/div>\n
    sudo mysql_secure_installation
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  4. Create a new MySQL database for Cacti:\n
    \n
    <\/div>\n
    mysql -u root -p<\/span>
    \nCREATE DATABASE cacti;
    \nGRANT ALL<\/span> ON cacti.* TO<\/span> cacti@localhost<\/span> IDENTIFIED BY 'password'<\/span>;
    \nFLUSH PRIVILEGES;
    \nexit;
    \n<\/code><\/div>\n<\/div>\n

    Replace ‘password’ with a strong password of your choice.<\/li>\n

  5. Import the default Cacti database schema into the new cacti<\/code> database:\n
    \n
    <\/div>\n
    sudo mysql -u cacti -p cacti < \/usr\/<\/span>share\/doc\/cacti\/cacti.sql<\/span>
    \n<\/code><\/div>\n<\/div>\n

    Enter the password you set for the cacti<\/code> MySQL user in step 4 when prompted.<\/li>\n

  6. Edit the Cacti configuration file \/etc\/cacti\/db.php<\/code> and set the MySQL database credentials:\n
    \n
    <\/div>\n
    sudo vi \/etc\/cacti\/db.php
    \n$database_type<\/span> = \"mysql\"<\/span>;
    \n$database_default<\/span> = \"cacti\"<\/span>;
    \n$database_hostname<\/span> = \"localhost\"<\/span>;
    \n$database_username<\/span> = \"cacti\"<\/span>;
    \n$database_password<\/span> = \"password\"<\/span>;
    \n<\/code><\/div>\n<\/div>\n

    Replace ‘password’ with the password you set for the cacti<\/code> MySQL user in step 4.<\/li>\n

  7. Edit the Apache configuration file \/etc\/httpd\/conf.d\/cacti.conf<\/code> and add the following lines to allow access to the Cacti web interface from the local network:\n
    \n
    <\/div>\n
    <Directory \/usr\/share\/cacti\/>
    \n Options +FollowSymLinks
    \n AllowOverride None<\/span>
    \n Order<\/span> allow,deny
    \n Allow from<\/span> 192.168<\/span>.0.0<\/span>\/24<\/span>
    \n<\/Directory>
    \n<\/code><\/div>\n<\/div>\n

    Replace 192.168.0.0\/24<\/code> with the IP address range of your local network.<\/li>\n

  8. Edit the Cacti configuration file \/etc\/cacti\/cacti.conf<\/code> and set the timezone:\n
    \n
    <\/div>\n
    sudo vi \/etc\/cacti\/cacti.conf<\/span>
    \ndate_default_timezone<\/span> =<\/span> \"Europe\/London\"<\/span>
    \n<\/code><\/div>\n<\/div>\n

    Replace Europe\/London<\/code> with your timezone.<\/li>\n

  9. Start the Cacti and Apache services and configure them to start automatically on boot:\n
    \n
    <\/div>\n
    sudo systemctl start cacti
    \nsudo systemctl enable<\/span> cacti
    \nsudo systemctl start httpd
    \nsudo systemctl enable<\/span> httpd
    \n<\/code><\/div>\n<\/div>\n<\/li>\n
  10. Open your web browser and go to http:\/\/<cacti-server>\/cacti\/<\/code> to access the Cacti web interface. The default login credentials are admin<\/code> \/ admin<\/code>.<\/li>\n<\/ol>\n

    That’s it! You should now be able to use Cacti to monitor and graph various metrics about your network devices.<\/p>\n","protected":false},"excerpt":{"rendered":"
