Installing Cacti v0.8.7 and Spine v0.8.7 on CentOS 5.1
Howto install Cacti on a CentOS v5.1 VM
"Cacti is a complete network graphing solution designed to harness the power of RRDTool's data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices."
Standard prerequisites from a minimal CentOS 5.1 installation:
# yum update # yum install postfix vixie-cron crontabs screen mlocate man which logrotate
For CentOS 5, Cacti is available from the EPEL repostory and the DAG repository. The Cacti Spine package is only available from the DAG repostory. So that a consistent install is achieved, we don't install the EPEL repository.
Install the DAG RPM repository.
# rpm -Uhv http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
Install cacti and dependencies:
# yum install cacti cacti-spine mysql-server net-snmp-utils
Since the database is only required by local processes, ensure it only listens on the loopback interface in '/etc/my.cnf':
[mysqld] bind-address = localhost
Enable and start services (Note: Cacti runs with apache httpd out of the box).
# for A in httpd mysqld ; do chkconfig $A on ; service $A start ; done
Bootstrap and configure the
database
# mysqladmin create cacti # mysql mysql> GRANT USAGE ON *.* TO 'cactiuser'@'localhost' IDENTIFIED BY 'cactiuser'; mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, LOCK TABLES, ALTER ON cacti.* TO 'cactiuser'@'localhost'; mysql> flush privileges; # mysql cacti -u cactiuser -pcactiuser < /var/www/cacti/cacti.sql
The default configuration values are in '/usr/share/cacti/include/config.php' (change username cactiuser, password cactiuser to the values above), and for Spine in '/etc/spine.conf'.
Change the pooler to 'spine' (on the poller settings tab) and set the path to spine (on the paths tab).
Browse to http://cacti.lucidsolutions.co.nz/cacti. The default username 'admin', password 'admin'.
