Montar un cacti en 2 cliks

te aseguras que en tu repositorio yum tengas, además de lo típico, algo así:

root@localhost ~]# cat /vz/template/centos/5/i386/config/yum.conf
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

# Name: RPMforge RPM Repository for Red Hat Enterprise 5 – dag
# URL: http://rpmforge.net/
[RHEL5-rpmforge]
name = Red Hat Enterprise 5 – RPMforge.net – dag
#baseurl = http://apt.sw.be/redhat/el5/en/i386/dag
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
#gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 0

Luego te montas la maquina con algo del estilo:

vzctl create –ostemplate centos-5-i386-minimal –config split5
vzctl set –onboot yes –save
vzctl set –ipadd a.b.c.d –save
vzctl set –nameserver a.b.c.d –save
vzctl set –hostname cacti.pepep –save
vzctl start

Y con esto, el último paso es:

vzyum install cacti php-eaccelerator mysql-server crontabs joe tar gzip vixie-cron
