Hi all,
In my datacenter I've a configuration like this:
class apache2 ($max_fork=100, $monitor=true) {
# some implementation that utilize $max_fork and $monitor
variables
}
class mysql ($max_conn=200, $monitor=true) {
# some implementation that utilize $max_conn and $monitor
variables
}
class php ($max_execution_time=10){
# some implementation that utilize $max_execution_time variable
}
class webserver ($max_fork=100,$max_execution_time=10, $monitor=true)
{
class { 'apache2' :
max_fork => $max_fork,
monitor => $monitor
}
class { 'php' :
max_execution_time => $max_execution_time
}
}
class db ($max_conn=200, $monitor=true) {
class { 'mysql' :
max_conn => $max_conn,
monitor => $monitor
}
}
class completeserver ($max_fork, $max_execution_time, $max_conn,
$monitor) {
class { 'webserver' :
max_fork => $max_fork,
max_execution_time => $max_execution_time,
monitor => $monitor
}
class { 'db' :
max_conn => $max_conn,
monitor => $monitor
}
}
node example {
$max_fork=200
$max_execution_time=30
$max_conn=500
$monitor=false
class { 'completeserver':
max_fork => $max_fork,
max_conn => $max_conn,
max_execution_time => $max_execution_time,
monitor => $monitor
}
}
This configuration works fine and allows me to override all parameters
in classes apache2, mysql, php directly on the node definition.
The problem is that I have to report any parameter present in every
base class through every classes that includes it. The result is that
completeserver class has all defined parameters and if I need to add
another parameter, for example, in apache2 class, I have to add this
parameter also in webserver class and completeserver class and this is
not so useful.
Has someone solved the same problem in a more elegant way?
Thanks in advance,
Fx
