    2. 설정파일 수정 
       $> vi /etc/puppet/puppet.conf
 ...
 [agent]
 certname=agent.localdomain
 runinterval = 60
 certname = 에이전트 호스트네임 추가, runinterval은 업데이트 주기(초단위)로 설정하면 됨.
 ...
$>  vi /etc/sysconfig/puppet 
...
PUPPET_SERVER에 마스터 서버 호스트네임 입력
PUPPET_LOG에 에이전트 로그파일 파일명 입력
    3. 서비스 시작 
      $>  /etc/init.d/puppet start
Starting puppet agent:                                     [  OK  ]
$>  ps -ef | grep puppet
root      1072     1  3 16:03 ?        00:00:00 /usr/bin/ruby /usr/bin/puppet agent --server=master.localdomain --logdest=/var/log/puppet/puppet.log
* 프로세스 실핵확인하면 됨

서버 연동하기

  1. 마스터서버에서 인증작업하기
    1. 인증이 필요한 클라이언트 확인 
      $>  puppet cert --sign --list
"agent.localdomain" (SHA256) 52:0D:EF:51:BB:50:99:FE:BC:6D:2F:33:CC:A9:43:73:3B:1C:C6:A1:D6:4C:D2:13:DE:AA:75:E9:7E:D2:2A:E5
* 도메인 옆에 +기호가 붙어있으면 인증이 완료된 에이전트 입니다.
    2. 에이전트 인증작업 수행 
      $>  puppet cert --sign agent.localdomain
Notice: Signed certificate request for agent.localdomain
Notice: Removing file Puppet::SSL::CertificateRequest agent.localdomain at '/var/lib/puppet/ssl/ca/requests/agent.localdomain.pem'
    3. 인증완료여부 확인 
      $>  puppet cert --sign --all --list
+ "agent.localdomain"  (SHA256) 9C:18:CA:26:73:CA:65:96:85:07:B1:F4:B7:A3:2C:43:FA:EE:63:3C:A7:A3:6C:CD:A2:51:5B:81:D2:E5:2D:3F
도메인 옆에 +기호가 생기면 완료.
      • 연동이 잘 되었는지 테스트.
    4. 아래 경로에서 파일생성 
      $> cat /etc/puppet/manifests/site.pp
file {
'/tmp/hello' :
 owner => root,
 group => root,
 mode => 444,
 content => "Hello Pupplet
by Machine\n";
}
      • /tmp/hello 파일이 생성되는데, 생성시 root의 사용자와 그룹으로 지정하여 생성하고 퍼미션은 444(read)생성하되, 텍스트 데이터는 Hello Pupplet라는 데이터로 저장
    5. pupplet 적용하기 
      $>  puppet apply  /etc/puppet/manifests/site.pp
Notice: Compiled catalog for master in environment production in 0.17 seconds
Notice: /Stage[main]/Main/File[/tmp/hello]/content: content changed '{md5}723c9d4525cebf11f4e6171740b15abd' to '{md5}7b1d27a85c9ebf03075ee2150fb4d770'
Notice: Finished catalog run in 0.09 seconds
에이전트)
/tmp/hello파일이 생성되었는지 확인
  2. Agent 작업하기 
    $>  ls -l /tmp/hello
-r--r--r-- 1 root root 25 Sep 14 16:11 /tmp/hello
$>  cat /tmp/hello
Hello Pupplet
by Machine
    • /tmp/hello파일이 생성되었는지 확인
