Puppet : How to use [service Resource]2023/10/17

	This is the examples for [service] resource.
[1]	It manages the configuration to keep [httpd] is running.

[root@dlp ~]#

vi /etc/puppetlabs/code/environments/production/manifests/svc01.pp

service { 'httpd':
  name   => 'httpd',
  ensure => running,
}

[2]	It manages the configuration to keep [httpd] is running. However, if [httpd] is not installed, [httpd] can not start of course, so it manages the configuration to keep [httpd] is installed with [require] parameter like follows.

[root@dlp ~]#

vi /etc/puppetlabs/code/environments/production/manifests/pkg01.pp

package { 'httpd':
  provider => yum,
  ensure   => installed,
}

[root@dlp ~]#

vi /etc/puppetlabs/code/environments/production/manifests/svc01.pp

service { 'httpd':
  name    => 'httpd',
  ensure  => running,
  require => Package['httpd'],
}

[3]	It manages the configuration to keep Nginx is not running. If running, it stops.

[root@dlp ~]#

vi /etc/puppetlabs/code/environments/production/manifests/svc02.pp

service { 'nginx':
  name   => 'nginx',
  ensure => stopped,
}

[4]	It restarts [httpd] when the file [/etc/httpd/conf.d/security.conf] is updated.

[root@dlp ~]#

vi /etc/puppetlabs/code/environments/production/manifests/svc03.pp

file { '/etc/httpd/conf.d/security.conf':
  ensure => file,
  owner  => 'root',
  group  => 'root',
  mode   => '0644',
  source => 'puppet://dlp.srv.world/extra_files/security.conf',
  notify => Service['httpd'],
}

[root@dlp ~]#

vi /etc/puppetlabs/puppet/files/security.conf
