========================================================================
  1. Buat user cacti untuk menjalankan database yang nanti akan dibuat untuk keperluan menyimpan database cacti
[root@cacti]# groupadd cacti
[root@cacti]# useradd –g cacti cactiuser
[root@cacti]# passwd cactiuser
Changing password for user cactiuser.
New UNIX password: “cactipassword”
Retype new UNIX password: “cactipassword”
passwd: all authentication tokens updated successfully.
  1. Install cacti ke DirectoryRoot webserver
[root@cacti]# cd /var/www/html/
[root@cacti]# tar –xzvf cacti-0.8.7g
[root@cacti]# mv cacti-0.8.7g cacti
  1. Membuat Database untuk cacti
[root@cacti]# mysqladmin –u root –p create cacti
Masuk ke directory cacti yang baru diinstall tadi
[root@cacti]# cd /var/www/html/cacti
Import database cacti yang sudah ada di directory tersebut ke database cacti yang baru saja dibuat
[root@cacti]# mysql –u root –p cacti < cacti.sql
“bila terjadi error pada saat import database, jalankan perintah berikut”
[root@cacti]# sed –I –e ‘s/TYPE=/ENGINE=/g’ /var/www/html/cacti/cacti.sql
  1. Buat user cacti di mysql untuk memanage database cacti
[root@cacti]# mysql –u root –p
mysql> GRANT ALLL ON cacti.* TO cactiuser@localhost IDENTIFIED BY “passwordnyacacti”;
mysql> flush privileges;
mysql> quit;
  1. Edit file configuration cacti yang berada di /var/www/html/cacti/include/config.php
[root@cacti]# vi /var/www/html/cacti/include/config.php
Pastikan konfigurasinya sama seperti konfigurasi yang dibuat diatas
----------------------------------------------------------------------------------------------------------------------------------
$database_type = “mysql”;
$database_default = “cacti”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “passwordnyacacti”;
$database_port = “3306”;
/* load up old style plugins here */
$plugins = array ();
//$plugins[] = ‘thold’;
$plugins[] = ‘aggregate’;
/*
Edit this to point to the default URL of your Cacti install
ex: if your cacti install as at http://ipserver/cacti/ this would be set to /cacti/
----------------------------------------------------------------------------------------------------------------------------------
  1. Ganti kepemilikan folder rra/ dan log/ menjadi cactiuser (user cacti yang dibuat di atas)
[root@cacti]# cd /var/www/html/cacti
[root@cacti]# chown –R cactiuser rra/ log/
  1. Buat file crontab agar cacti melakukan update setiap 5 menit
[root@cacti]# crontab –e
Isi file dengan:
----------------------------------------------------------------------------------------------------------------------------------
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php
----------------------------------------------------------------------------------------------------------------------------------
Restart httpd
[root@cacti]# /etc/init.d/httpd restart
  1. Saatnya mencoba cacti dari client
Buka browser, masukan alamat http://ipserver/cacti


Click Next > New Install > Next
