I'm using puppetlabs/apache to install apache. I already created 4
classes, apache24::install, apache24::modules, apache24::default_hosts
and apache::config to ensure the ordering of the installation process.
apache24::install includes apache{}, where I define "mpm_module =>
false," to be able to provide my own mpm_ module.
Then I call apache24::modules to install the appropriate mpm_ and other
modules.
Obviously the installation of cgi(d) checks the installation of a mpm_
module:
Error: Could not retrieve catalog from remote server: Error 400 on
SERVER: Could not find resource 'Class[Apache::Mod::Prefork]' for
relationship on 'Class[Apache::Mod::Cgi]' on node myhost
I therefore need to ensure that before all other modules an appropriate
mpm mpdule is installed
I helped mysqlf with
# mpm must be the first module to install
if /(mpm_.*)/ in $apacheModules {
$mpmModule = [ $1 ]
$apacheModulesTemp = delete($apacheModules, $mpmModule)
} else {
$apacheModulesTemp = $apacheModules
}
[...]
$apacheModulesRevised = concat($mpmModule, $apacheModulesTemp)
but was wondering if there is an easier/cleaner/better solution.
