    Can you give step for cacti configuration.

      Hi Manish

      * Once you have all the rpm’s downloaded install them using this command: rpm -i ‘filename’
      If you run into problems installing the rpms you can do rpm -i –force ‘filename’ to force the install.
      rpm -q file – will display the current version of the rpm installed. Rpm -e ‘filename’ will remove the rpm.

      * Once all the rpms are install go ahead and unzip Cacti and RRDtool. Use the following command: tar -zxvf ‘filename’

      5. Follow the instructions that come with RRDtool to install RRDtool.

      6.Follow the instructions that come with Cacti to install Cacti.

      * Create a new user account called ‘cactiuser’ on your box.

      * Once you have RRDtool and cacti installed do the following:
      a. Go into the directory where you have cacti – usually /var/www/html/cacti
      b. Once there create the mysql database:
      shell> mysqladmin –user=root create cacti
      shell> mysql cacti mysql –uer=root mysql

      mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY ‘somepassword’;

      mysql> flush privileges;

      * Edit the config.php file. Located in the cacti/include directory.
      Change the database name, house, username, password as you specified above.

      $database_default = “cacti”;
      $database_hostname = “localhost”;
      $database_username = “cactiuser”;
      $database_password = “cacti”;

      * As root change the permissions the /rra and /log Directories.

      shell> chown cactiuser rra/ log/

      * Change user to the user account cactiuser that you created in step 7.

      * Create a crontab which will run the cmd.php every five mintues.

      shell > crontab -e
      Then press ‘insert’ on the keyboard – this allows you to type.
      */5 * * * * cactiuser php /var/www/html/cacti/cmd.php > /dev/null 2>&1
      Then press ESC – this remove your typing capability.
      press: Shift ZZ – this will save and exit the crontab.

      *Point your web browser to and follow the directions:

  17. Vishal Vyas June 28, 2011 at 6:52 am #

    rpm –help or…

    rpm -qa :- Display list all installed packages

    rpm -qi ftp :- Display installed information along with package version and short description

    rpm -qf /etc/passwd :- Find out what package a file belongs to i.e. find what package owns the file

    rpm -qc httpd :- Display list of configuration file(s) for a package

    rpm -qa –last :- Display list of all recently installed RPMs

    rpm -qR bash :- Find out what dependencies a rpm file has
