    Hi. I make what is missing?
    http://prntscr.com/ba6os9
    Images do not appear :/

    • Ravi Saive says:

      @Volkan,

      Thanks for sharing the screenshot, I think it’s due to SELinux, could you disable it and check again?

      • Volkan says:

        Thank you Ravi. I could not find a solution, and erased everything :D Now I’ll try to install again. (CentOS 6.8 64BIT)

        • Ravi Saive says:

          @Volkan,

          Good luck, and make sure to follow instructions carefully, if you stuck somewhere around while installing Cacti, do comment here, I will love to help you out..

          • Volkan says:

            Thank you Ravi. I found my mistake.;
            #*/5 * * * * cacti /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1
            I delete the # sign :D
            Now it is running smoothly.
            I’ll try to build add-ons. (plugins)

          • Ravi Saive says:

            @Volkan,

            I am glad that finally you found the mistake yourself and corrected, good luck for rest of things..

    HI Ravi,

    Just want to know why my graph all show “rrd file does not exist”?

    • Ravi Saive says:

      @Dennis,

      Please let me know what’s the group:owner permission of rrd files and directory? it should be apache:apache to function properly..

      • Dennis says:

        [root@hpdcentos3 ~]# ls -l /usr/share | grep rrd
        drwxr-xr-x. 2 root root 6 Nov 21 2015 rrdtool
        [root@hpdcentos3 ~]# ls -l /usr/share/cacti/lib | grep rrd
        -rw-r–r–. 1 root root 91557 Feb 8 03:26 rrd.php

        • Ravi Saive says:

          @Dennis,

          It should be user/group apache, change the rrd directory and files ownership to apache recursively as shown

          # chown -R apache:apache path-to-rrd-directory

  4. Gabriel says:

    After installing and doing all the steps of the guide I go to my cacti page and see just a blank page. Please your help I’m trying to install this server for 2 weeks now.

    Thanks

    • Ravi Saive says:

      @Gabriel,

      Sorry to hear that, may I know on which Linux distributions you’re trying? and you’ve followed cacti installation instructions correctly, could you give a try again? or else give me access to your server, let me setup for you for free.

  5. Plaza says:

    I followed all the steps and all I see is a blank page, please your help with this.

    • Ravi Saive says:

      @Plaza,

      Please let me know on which Linux distributions you’re trying to install cacti? have you installed all required packages correctly?
