Server and Client

In server, install following packages:

$ sudo apt-get install puppet puppetmaster

In client, only install puppet is enough.
After installation, added the each other’s name into /etc/hosts, let them ping each other via name rather than via ip address.

Sign

In client, do following:

$ clouder@pc121:/etc/puppet$ puppet agent --test --server=pc119
Exiting; no certificate found and waitforcert is disabled

Then in server, listed all of the certification request:

root@pc119:~/Code/herokublog# sudo puppet cert list
  "pc121" (SHA256) 28:23:36:3C:E4:8B:3A:15:D2:B0:8C:A2:BC:E9:A1:E5:6A:6F:76:0E:40:73:29:1F:8F:8C:D4:83:1F:92:4F:C7

sign the cert:

root@pc119:~/Code/herokublog# sudo puppet cert sign pc121
Notice: Signed certificate request for pc121
Notice: Removing file Puppet::SSL::CertificateRequest pc121 at '/var/lib/puppet/ssl/ca/requests/pc121.pem'

Verify it in the client:

clouder@pc121:/etc/puppet$ puppet agent --test
