Cacti<\/strong>\u00a0tool is an open source web based network monitoring and system monitoring graphing solution for\u00a0IT<\/strong>business. Cacti enables a user to poll services at regular intervals to create graphs on resulting data using\u00a0RRDtool<\/strong>. Generally, it is used to graph time-series data of metrics such as\u00a0network bandwidth utilization<\/strong>,\u00a0CPU load<\/strong>,\u00a0running processes<\/strong>,\u00a0disk space<\/strong>\u00a0etc.<\/p>\n

    Installing Cacti Required Packages on RHEL \/ CentOS \/ Fedora<\/h3>\n

    First, we need to install following dependency packages one-by-one using\u00a0YUM<\/strong>\u00a0package manager tool.<\/p>\n

    Recently,\u00a0RedHat<\/strong>\u00a0makes a new transaction from MySQl to MariaDB, as MariaDB is the default implementation of MySQL in\u00a0RHEL\/CentOS 7.x<\/strong>\u00a0and\u00a0Fedora 19<\/strong>\u00a0onwards..<\/p>\n

    Configuring Apache Server for Cacti Installation<\/h3>\n
    Open file called\u00a0\/etc\/httpd\/conf.d\/cacti.conf<\/strong>\u00a0with your choice of editor.<\/p>\n
    # vi \/etc\/httpd\/conf.d\/cacti.conf\r\n<\/pre>\n
    You need to enabled access to\u00a0Cacti<\/strong>\u00a0application for your local network or per IP level. For example we’ve enabled access to our local LAN network\u00a0172.16.16.0\/20<\/strong>. In your case, it would be different.<\/p>\n
    Alias \/cacti    \/usr\/share\/cacti\r\n\u00a0\r\n<Directory \/usr\/share\/cacti\/>\r\n        Order Deny,Allow\r\n        Deny from all\r\n        Allow from 172.16.16.0\/20<\/strong>\r\n<\/Directory>\r\n<\/pre>\n
    In latest version of Apache (ex:\u00a0Apache 2.4<\/strong>), you may need to change according to the following settings.<\/p>\n
    Alias \/cacti    \/usr\/share\/cacti\r\n\r\n<Directory \/usr\/share\/cacti\/>\r\n        <IfModule mod_authz_core.c>\r\n                # httpd 2.4\r\n                Require all granted<\/strong>\r\n        <\/IfModule>\r\n        <IfModule !mod_authz_core.c>\r\n                # httpd 2.2\r\n                Order deny,allow\r\n                Deny from all\r\n                Allow from all\r\n        <\/IfModule>\r\n<\/Directory>\r\n<\/pre>\n
    Finally, restart the\u00a0Apache<\/strong>\u00a0service.<\/p>\n
    [root@tecmint ~]# service httpd restart\t\t\t\t[On RHEL\/CentOS 6.x\/5.x and Fedora 18-12]\r\n\r\n[root@tecmint ~]# systemctl restart httpd.service\t\t[On RHEL\/CentOS 7.x and Fedora 19 onwards]\r\n<\/pre>\n
