Hi, all
I have some questions about the execution sequence in puppet.
*The background:*
I want to install mysql package and configure /etc/my.cnf according to
the version of mysql. So I wrote an user defined function to get mysql rpm
version. Codes are as follows.
------------------------------------------------
class mysql {
package { 'mysql':
ensure => latest,
}
$mysql_version = get_pkg_version("mysql")
file { '/etc/my.cnf':
ensure => present,
mode => '0644',
content => template('mysql/mysql.cnf'),
require => Package['mysql'],
}
}
Note: get_pkg_version is the user defined function to get mysql rpm
version.
-------------------------------------------------------------------------------------------
*Issue:*
The first time I execute *puppet agent -t*, the variable
*mysql_version*couldn't get the version of mysql. And I found it was executed
before the
installation of mysql package. And the second time I execute *puppet agent
-t*, the variable *mysql_version* got the version of mysql installed after
the first time.
So, my question is that are variables assignment executed before the
resources such as Package, Service, File..etc?
Is there any method can make *$mysql_version = get_pkg_version("mysql")
*executed
after *Package['mysql']*?
Really looking forward to your answers!
