| [4] | Verify Puppet Server and Client work normally to create a test manifest. Puppet clients apply manifests on Puppet server for every 30 minutes by default, so wait for a moment to make sure the setting or if you'd like to make sure at once, reload Puppet Client daemon. |

# create a directory for putting manifests # for the name [production], specify the name set for [environment = ***] parameter in [puppet.conf] root@dlp:~# mkdir -p /etc/puppetlabs/code/environments/production/manifests
root@dlp:~#
vi /etc/puppetlabs/code/environments/production/manifests/site.pp # for example, create a [testgroup]
group { 'testgroup':
ensure => present,
gid => 2000,
}
# on Client host, reload puppet if you like to verify settings immediately root@node01:~# systemctl reload puppet
grep testgroup /etc/group testgroup:x:2000: |
| [5] | If you like to apply manifest manually on localhost, run like follows. |
